Thus, as the number of software solutions increases, the need for robust security also increases. 8. Wide Use of PWA in the Future of Software Development PWA is an acronym for Progressive Web Applications. This app is made using web tools that we are all familiar with and enjoy, such as HTML, CSS, and JS, but with the feel and functionality of a native application. So users get easy access to their web pages. This implies that you can create a PWA rather rapidly than developing native software. Additionally, you may provide all of the functionality found in native applications, such as push notifications and offline support. It is undoubtedly one of the most cost-effective approaches for creating mobile apps that work on various platforms. 9. Need for Implementation of Cybersecurity Cybersecurity continues to be a significant responsibility for businesses that must safeguard sensitive data to protect their projects from cybercriminal attacks. Traditional security measures are becoming obsolete over time. Financial organizations, in particular, have to be able to reassure their clients that their data is safe behind an impenetrable digital lock, which is why the cybersecurity business continues to be a hot development topic. Cyber assaults are growing cleverer and more imaginative, which implies that security should be beefed up to protect enterprises from them. Cybersecurity will almost certainly play a significant role in the future of software development and engineering. 10. Application of Deep Learning Libraries Due to the impact of deep learning in data mining and pattern identification, industry practitioners and academics have been increasingly integrating deep learning into SE problems in recent years, being a software development trend. Deep learning enables SE participants to extract required data from natural language text, produce source code, and anticipate software flaws, among other things. Here are two prominent frameworks used to implement deep learning in software development. Google’s TensorFlow: TensorFlow 2.0 included a dynamic graph, Python compatibility, and other modifications. Additionally, it includes TensorFlow.js, which enables browser-based usage of the AI framework. TensorFlow’s other breakthrough is TensorFlow Lite, which enables the deployment of TensorFlow on mobile and web platforms. Additionally, TensorFlow announced TensorFlow Extended. It is a platform for deploying machine learning pipelines in SE. Facebook’s PyTorch: PyTorch is another widely used AI package that made Dynamic Graph and Python first-class citizens. It is more developer-friendly and offers PyTorch Mobile, which enables users to utilize PyTorch on Android/iOS smartphones. It provides increased developer friendliness when used with PyTorch Profiler to debug AI models. 11. Prevalent Use of Multi-Model and Multi-Purpose Databases A multi-model database is a database management system that enables the organization of many NoSQL data models using a single backend. A unified query language and API is offered that supports all NoSQL models and allows for their combination in a single query. Multi-model databases effectively prevent fragmentation by providing a uniform backend that supports a diverse range of goods and applications. Multi-model databases may be built using polyglot persistence. One disadvantage of this method is that many databases are often required for a single application. There is a growing trend toward databases offering many models and supporting several use cases. These databases are forerunners of Azure CosmosDB, PostgreSQL, and SingleStore. Additionally, in 2024, we should see other databases that support several models and purposes. 12. API Technology in the Mainstream For decades, the application programming interface (API) has been a critical component of software development developed for a particular platform, like Microsoft Windows. Recent platform providers, ranging from Salesforce to Facebook and Google, have introduced developer-friendly APIs, creating a developer reliance on these platforms. Here are the three most popular API technologies that will rule the future world. REST: REST is the earliest of these technologies, having been created around 2000. Client-server communication is accomplished using the World Wide Web and HTTP technologies. It is the most established and commonly utilized. gRPC: gRPC was developed by Google as a server-to-server data transfer API based on the legacy Remote Procedure Call technology. Each request is organized like a function call in this case. Unlike REST, which communicates using a textual format, gRPC communicates using a protocol buffer-based binary format. Consequently, gRPC is more efficient and speedier than REST regarding service-to-service data transfer. GraphQL: The Web client-to-server connection will include several round trips if the data structure is complicated. To address this problem, Facebook created the GraphQL API. Each client may describe the form of the data structure for a particular use case and get all the data in a single trip using GraphQL. Wrapping Up About the Future of Software Development Software development is considered a fascinating and lucrative business. It has been indispensable in the development of billion-dollar brands. The possibilities projected by cloud computing, AI, and all other aspects of the future software development trends. However, writing software has its challenges. In the previous 40 years, major advancements have occurred in hardware, software, and technology that underpin these two dualities. Entrepreneurs and businesses who were inventive and stayed current with trends flourished, whereas those that were complacent fell behind and were forgotten. Understanding the condition of software development today and what is the future of software development might be the difference between success and failure for your business. It enables you to adopt processes, strategies, financing, and other changes that will increase earnings, industry leadership, and commercial success.

In today's highly competitive landscape, businesses must be able to gather, process, and react to data in real-time in order to survive and thrive. Whether it's detecting fraud, personalizing user experiences, or monitoring systems, near-instant data is now a need, not a nice-to-have. However, building and running mission-critical, real-time data pipelines is challenging. The infrastructure must be fault-tolerant, infinitely scalable, and integrated with various data sources and applications. This is where leveraging Apache Kafka, Python, and cloud platforms comes in handy. In this comprehensive guide, we will cover: An overview of Apache Kafka architecture Running Kafka clusters on the cloud Building real-time data pipelines with Python Scaling processing using PySpark Real-world examples like user activity tracking, IoT data pipeline, and support chat analysis We will include plenty of code snippets, configuration examples, and links to documentation along the way for you to get hands-on experience with these incredibly useful technologies. Let's get started! Apache Kafka Architecture 101 Apache Kafka is a distributed, partitioned, replicated commit log for storing streams of data reliably and at scale. At its core, Kafka provides the following capabilities: Publish-subscribe messaging: Kafka lets you broadcast streams of data like page views, transactions, user events, etc., from producers and consume them in real-time using consumers. Message storage: Kafka durably persists messages on disk as they arrive and retains them for specified periods. Messages are stored and indexed by an offset indicating the position in the log. Fault tolerance: Data is replicated across configurable numbers of servers. If a server goes down, another can ensure continuous operations. Horizontal scalability: Kafka clusters can be elastically scaled by simply adding more servers. This allows for unlimited storage and processing capacity. Kafka architecture consists of the following main components: Topics Messages are published to categories called topics. Each topic acts as a feed or queue of messages. A common scenario is a topic per message type or data stream. Each message in a Kafka topic has a unique identifier called an offset, which represents its position in the topic. A topic can be divided into multiple partitions, which are segments of the topic that can be stored on different brokers. Partitioning allows Kafka to scale and parallelize the data processing by distributing the load among multiple consumers. Producers These are applications that publish messages to Kafka topics. They connect to the Kafka cluster, serialize data (say, to JSON or Avro), assign a key, and send it to the appropriate topic. For example, a web app can produce clickstream events, or a mobile app can produce usage stats. Consumers Consumers read messages from Kafka topics and process them. Processing may involve parsing data, validation, aggregation, filtering, storing to databases, etc. Consumers connect to the Kafka cluster and subscribe to one or more topics to get feeds of messages, which they then handle as per the use case requirements. Brokers This is the Kafka server that receives messages from producers, assigns offsets, commits messages to storage, and serves data to consumers. Kafka clusters consist of multiple brokers for scalability and fault tolerance. ZooKeeper ZooKeeper handles coordination and consensus between brokers like controller election and topic configuration. It maintains cluster state and configuration info required for Kafka operations. This covers Kafka basics. For an in-depth understanding, refer to the excellent Kafka documentation. Now, let's look at simplifying management by running Kafka in the cloud. Kafka in the Cloud While Kafka is highly scalable and reliable, operating it involves significant effort related to deployment, infrastructure management, monitoring, security, failure handling, upgrades, etc. Thankfully, Kafka is now available as a fully managed service from all major cloud providers: Service Description Pricing AWS MSK Fully managed, highly available Apache Kafka clusters on AWS. Handles infrastructure, scaling, security, failure handling etc. Based on number of brokers Google Cloud Pub/Sub Serverless, real-time messaging service based on Kafka. Auto-scaling, at least once delivery guarantees. Based on usage metrics Confluent Cloud Fully managed event streaming platform powered by Apache Kafka. Free tier available. Tiered pricing based on features Azure Event Hubs High throughput event ingestion service for Apache Kafka. Integrations with Azure data services. Based on throughput units The managed services abstract away the complexities of Kafka operations and let you focus on your data pipelines. Next, we will build a real-time pipeline with Python, Kafka, and the cloud. You can also refer to the following guide as another example. Building Real-Time Data Pipelines A basic real-time pipeline with Kafka has two main components: a producer that publishes messages to Kafka and a consumer that subscribes to topics and processes the messages. The architecture follows this flow: We will use the Confluent Kafka Python client library for simplicity. 1. Python Producer The producer application gathers data from sources and publishes it to Kafka topics. As an example, let's say we have a Python service collecting user clickstream events from a web application. In a web application, when a user acts like a page view or product rating, we can capture these events and send them to Kafka. We can abstract the implementation details of how the web app collects the data. Python from confluent_kafka import Producer import json # User event data event = { "timestamp": "2022-01-01T12:22:25", "userid": "user123", "page": "/product123", "action": "view" } # Convert to JSON event_json = json.dumps(event) # Kafka producer configuration conf = { 'bootstrap.servers': 'my_kafka_cluster-xyz.cloud.provider.com:9092', 'client.id': 'clickstream-producer' } # Create producer instance producer = Producer(conf) # Publish event producer.produce(topic='clickstream', value=event_json) # Flush and close producer producer.flush() producer.close() This publishes the event to the clickstream topic on our cloud-hosted Kafka cluster. The confluent_kafka Python client uses an internal buffer to batch messages before sending them to Kafka. This improves efficiency compared to sending each message individually. By default, messages are accumulated in the buffer until either: The buffer size limit is reached (default 32 MB). The flush() method is called. When flush() is called, any messages in the buffer are immediately sent to the Kafka broker. If we did not call flush(), and instead relied on the buffer size limit, there would be a risk of losing events in the event of a failure before the next auto-flush. Calling flush() gives us greater control to minimize potential message loss. However, calling flush() after every production introduces additional overhead. Finding the right buffering configuration depends on our specific reliability needs and throughput requirements. We can keep adding events as they occur to build a live stream. This gives downstream data consumers a continual feed of events. 2. Python Consumer Next, we have a consumer application to ingest events from Kafka and process them. For example, we may want to parse events, filter for a certain subtype, and validate schema. Python from confluent_kafka import Consumer import json # Kafka consumer configuration conf = {'bootstrap.servers': 'my_kafka_cluster-xyz.cloud.provider.com:9092', 'group.id': 'clickstream-processor', 'auto.offset.reset': 'earliest'} # Create consumer instance consumer = Consumer(conf) # Subscribe to 'clickstream' topic consumer.subscribe(['clickstream']) # Poll Kafka for messages infinitely while True: msg = consumer.poll(1.0) if msg is None: continue # Parse JSON from message value event = json.loads(msg.value()) # Process event based on business logic if event['action'] == 'view': print('User viewed product page') elif event['action'] == 'rating': # Validate rating, insert to DB etc pass print(event) # Print event # Close consumer consumer.close() This polls the clickstream topic for new messages, consumes them, and takes action based on the event type - prints, updates database, etc. For a simple pipeline, this works well. But what if we get 100x more events per second? The consumer will not be able to keep up. This is where a tool like PySpark helps scale out processing. 3. Scaling With PySpark PySpark provides a Python API for Apache Spark, a distributed computing framework optimized for large-scale data processing. With PySpark, we can leverage Spark's in-memory computing and parallel execution to consume Kafka streams faster. First, we load Kafka data into a DataFrame, which can be manipulated using Spark SQL or Python. Python from pyspark.sql import SparkSession # Initialize Spark session spark = SparkSession.builder \ .appName('clickstream-consumer') \ .getOrCreate() # Read stream from Kafka 'clickstream' df = spark.readStream \ .format("kafka") \ .option("kafka.bootstrap.servers", "broker1:9092,broker2:9092") \ .option("subscribe", "clickstream") \ .load() # Parse JSON from value df = df.selectExpr("CAST(value AS STRING)") df = df.select(from_json(col("value"), schema).alias("data")) Next, we can express whatever processing logic we need using DataFrame transformations: from pyspark.sql.functions import * # Filter for 'page view' events views = df.filter(col("data.action") == "view") # Count views per page URL counts = views.groupBy(col("data.page")) .count() .orderBy("count") # Print the stream query = counts.writeStream \ .outputMode("complete") \ .format("console") \ .start() query.awaitTermination() This applies operations like filter, aggregate, and sort on the stream in real-time, leveraging Spark's distributed runtime. We can also parallelize consumption using multiple consumer groups and write the output sink to databases, cloud storage, etc. This allows us to build scalable stream processing on data from Kafka. Now that we've covered the end-to-end pipeline let's look at some real-world examples of applying it. Real-World Use Cases Let's explore some practical use cases where these technologies can help process huge amounts of real-time data at scale. User Activity Tracking Many modern web and mobile applications track user actions like page views, button clicks, transactions, etc., to gather usage analytics. Problem Data volumes can scale massively with millions of active users. Need insights in real-time to detect issues and personalize content Want to store aggregate data for historical reporting Solution Ingest clickstream events into Kafka topics using Python or any language. Process using PySpark for cleansing, aggregations, and analytics. Save output to databases like Cassandra for dashboards. Detect anomalies using Spark ML for real-time alerting. IoT Data Pipeline IoT sensors generate massive volumes of real-time telemetry like temperature, pressure, location, etc. Problem Millions of sensor events per second Requires cleaning, transforming, and enriching Need real-time monitoring and historical storage Solution Collect sensor data in Kafka topics using language SDKs. Use PySpark for data wrangling and joining external data. Feed stream into ML models for real-time predictions. Store aggregate data in a time series database for visualization. Customer Support Chat Analysis Chat platforms like Zendesk capture huge amounts of customer support conversations. Problem Millions of chat messages per month Need to understand customer pain points and agent performance Must detect negative sentiment and urgent issues Solution Ingest chat transcripts into Kafka topics using a connector Aggregate and process using PySpark SQL and DataFrames Feed data into NLP models to classify sentiment and intent Store insights into the database for historical reporting Present real-time dashboards for contact center ops This demonstrates applying the technologies to real business problems involving massive, fast-moving data. Learn More To summarize, we looked at how Python, Kafka, and the cloud provide a great combination for building robust, scalable real-time data pipelines.

Improving an organization's overall data capabilities enables teams to operate more efficiently. Emerging technologies have brought real-time data closer to business users, which plays a critical role in effective decision-making. In data analytics, the "hot path" and "cold path" refer to two distinct processing routes for handling data. The hot path involves real-time or near-real-time processing of data, where information is analyzed and acted upon immediately as it arrives. This path is crucial for time-sensitive applications, enabling quick responses to emerging trends or events. On the other hand, the cold path involves the batch processing of historical or less time-sensitive data, allowing for in-depth analysis, long-term trends identification, and comprehensive reporting, making it ideal for strategic planning and retrospective insights in data analytics workflows. In typical analytics solutions, the integration of incoming telemetry data with corresponding meta-data related to entities such as devices, users, or applications is a prerequisite on the server side before effective visualization in an application can occur. In this article, we will explore innovative methodologies for seamlessly combining data from diverse sources so that an effective dashboard can be built. The Event-Driven Architecture for Real-Time Anomalies Let's explore a real-time dashboard wherein administrators meticulously monitor network usage. In this scenario, live data on network usage from each device is transmitted in real-time, undergoing aggregation on the server side, inclusive of associating the data with respective client names before refreshing the user's table. In such use cases, the implementation of Event-Driven architecture patterns emerges as the optimal approach for ensuring seamless data processing and real-time insights. Event-driven design seamlessly orchestrates data flow between disparate microservices, enabling the aggregation of critical data points. Through clearly defined events, information from two distinct microservices is aggregated, ensuring real-time updates. The culmination of this event-driven approach provides a comprehensive and up-to-date representation of key metrics and insights for informed decision-making. In the depicted scenario, the telemetry data is seamlessly transmitted to the service bus for integration into the Dashboard service. Conversely, device metadata exhibits infrequent changes. Upon receipt of new telemetry events, the Dashboard service dynamically augments each record with all relevant metadata, presenting a comprehensive dataset for consumption by APIs. This entire process unfolds in real-time, empowering administrators to promptly identify network anomalies and initiate timely corrective measures. This methodology proves effective for those real-time scenarios, characterized by frequent incremental data ingestion to the server and a resilient system for processing those events. The Materialized View Architecture for Historical Reports For a historical report dashboard, adopting an event-driven approach might entail unnecessary effort, given that real-time updates are not imperative. A more efficient strategy would involve leveraging PostgreSQL Materialized Views, which is particularly suitable for handling bursty data updates. This approach allows for scheduled data crunching at predefined intervals, such as daily, weekly, or monthly, aligning with the periodic nature of the reporting requirements. PostgreSQL Materialized Views provide a robust mechanism for persistently storing the results of complex joins between disparate tables as physical tables. One of the standout advantages of materialized views is their ability to significantly improve the efficiency of data retrieval operations in APIs, as a considerable portion of the data is pre-computed. The incorporation of materialized views within PostgreSQL represents a substantial performance boost for read queries, particularly beneficial when the application can tolerate older, stale data. This feature serves to reduce disk access and streamline complex query computations by transforming the result set of a view into a tangible physical table. Let’s look at the above example with Device telemetry and metadata tables. The mat view can be created by the command below in SQL. SQL CREATE MATERIALIZED VIEW device_health_mat AS SELECT t.bsod_count, t.storage_used, t.date FROM device_telemetry t INNER JOIN device d ON t.ID = d.ID WITH DATA; Materialized views are beneficial in data warehousing and business intelligence applications where complex queries, data transformation, and aggregations are the norms. You can leverage materialized views when you have complex queries powering user-facing visualizations that need to load quickly to provide a great user experience. The only bottleneck with them is that the refresh needs to be explicitly done when the underlying tables have new data and can be scheduled with the command below. SQL REFRESH MATERIALIZED VIEW device_health_mat; (or) REFRESH MATERIALIZED VIEW CONCURRENTLY device_health_mat; In conclusion, while both aforementioned use cases share a dashboard requirement, the selection of tools and design must be meticulously tailored to the specific usage patterns to ensure the effectiveness of the solution.

Across diverse industries, spanning from manufacturing to healthcare, an abundance of sensors and other IoT devices diligently gather information and produce insightful data every day. Oftentimes, this data then needs to be passed down to some storage, processed accordingly, and acted upon if needed. In recent years, with the rise of cloud computing in the software industry, cloud platforms are becoming the central hub for such purposes, and the terms cloud computing and the Internet of Things are being mentioned together more and more frequently. In this article, you'll gain insights into the advantages, challenges, and pivotal role of cloud computing in the IoT ecosystem. Explanation of IoT and Cloud Computing Let’s start with the basics. Cloud computing delivers computing services, such as servers, storage, databases, networking, software, and more, over the Internet (‘the cloud’). The Internet of Things describes the network of physical objects embedded with sensors, software, and other technologies to connect and exchange information with other devices and systems over the Internet. The Internet of Things technology tends to build an ecosystem of devices that generate data and can communicate with one another. On the other hand, cloud computing allows to store, process, and accessing the collected data from anywhere, at any time. Combining these two technologies has brought a new term to our lives — Cloud Internet of Things. In simple terms, the Cloud Internet of Things is an IoT infrastructure connected to cloud services. It uses cloud computing services to collect and process information from IoT devices and manage these devices remotely. Since the cloud systems are scalable, it’s possible to process large amounts of data simultaneously. How Does IoT Cloud Computing Generally Work? Cloud IoT is an architecture that connects all the necessary IoT devices to cloud-based servers, resulting in real-time data analytics, data-driven decision-making, optimization, and risk mitigation. In practice, IoT cloud computing basically means there is a network of IoT devices that gather data and transmit it to the cloud for further processing, analysis, and storage. This can be broken down into the following steps: Data gathering (via IoT devices) Transmission to the cloud Data processing Data analysis Decision making Possible feedback loop back to the IoT devices if certain action needs to be taken based on the previous step. Data storage Note that “decision making,” “data analysis,” and “data storage” are not strictly ordered. In fact, even “transmission to the cloud” and “data processing” can switch places if one utilizes edge computing, whereby some data is processed and aggregated on the level of IoT devices or within the IoT network before sending the already processed (or partially processed) and aggregated data to the cloud, which ultimately saves the network bandwidth and decreases latency since the volume of the outgoing data is being decreased. On the cloud, there is some application/service that collects the gathered data, processes it (if needed), performs on-the-fly analysis, and/or stores the data in the database. This data can later be accessed for further analytics or monitoring purposes. If we, for instance, have sensors that gather some metrics about devices in some factory, we could later monitor this data on the cloud to check for potential malfunctioning of any devices or anomalies of any kind. This process can, of course, be fully automated. Another simplified example can be a data center facility with some temperature sensors that send data to the cloud. Then, if the temperature rises, the cloud application could notice it, make a decision, and send a command back to the facility to spin up more fans for better cooling, as well as a notification to the staff. Cloud vs. On-Premises Solutions When talking about the cloud, we typically mean solutions provided by cloud providers. Another option is to operate the entire infrastructure similar to that of a cloud yourself on the premises of the company (typically referred to as on-prem solutions). The difference between the two is obvious: in the former case, the data is sent to external cloud providers, and in the latter, we have to manage everything ourselves internally. The above-mentioned fact might raise some concerns and questions: whether it makes sense to transfer the data to a third party, especially in terms of security, data privacy, and peace of mind. The fact is that on-premises solutions can, in principle, have the same level of functionality and should, in theory, have superior security than third-party cloud services since the data never leaves the company. However, an important thing is to understand that on-premises solutions can achieve a higher security level only if security is done right. We have to take into account that security is hard, and implementing everything yourself can result in many hidden vulnerabilities. On the other hand, well-established cloud providers service thousands of companies and invest heavily in their security, trying to incorporate many industry standards and best practices. They also typically provide readily available, highly customizable, and easily scalable web services that can be configured to the particular needs of your business and would be very challenging for a smaller company to implement on their own. This is to underline the idea that a lot of smaller companies can benefit from using the existing cloud platforms that provide vast functionality and rigorous security. In comparison, bigger companies with a lot of resources might consider investing in implementing an on-premise solution specifically tailored to all the requirements and policies they might have. Benefits of Cloud Computing for IoT Now that we have established a distinction between cloud and on-premise computing for IoT let’s consider some important benefits of the cloud IoT platforms: 1. Ease of Implementation As mentioned in the previous section, the main benefit of cloud platforms is not having to spend additional time and resources on developing the data collection and processing infrastructure. Cloud offerings provide many out-of-the-box features suitable for a wide range of use cases. 2. Data Accessibility and Mobility Data on the cloud can be easily accessed from anywhere, anytime, without the need for a VPN to be configured, which also allows you to hook in additional services to your cloud that will consume this data for their purposes. In addition, clouds can be accessed from any device, increasing the convenience of use and providing the ability to control and monitor your IoT fleet from mobile devices. What’s also important is that the collected data can usually be distributed, transferred to a different server (which might be geographically closer for example), or be easily moved to some other service within the cloud. 3. Integration With Other Services Apart from being able to integrate your own or external services with the cloud, cloud platforms themselves offer a vast array of additional solutions for processing real-time data, predictive analytics, automated responses, and AI-driven decision-making. 4. Scalability Many cloud services feature extensive scaling capabilities that can be configured and enabled for your systems, ensuring higher performance in cases of traffic volume growth. 5. Data Security and Reliability Well-reputed cloud providers take security seriously and provide a lot of relevant features and safety measures. Many of these features have to, of course, be used and correctly configured by the customers, but the general set is extensive enough to provide comprehensive security for your systems without many pitfalls associated with implementing security on your own from scratch. 6. Cost-Effectiveness When using cloud services, you usually pay for what you utilize, which might be much more cost-effective than the high investments into developing and maintaining your own computing, analytics, and storage infrastructures. 7. Resilience Many clouds feature distributed solutions with high availability that make sure there is no single point of failure, enhancing resilience. On top of that, it is usually possible to configure automated backups of your data to ensure its safety. 8. Maintenance and Updates Cloud providers regularly update and maintain their systems and hardware, which is something that can be easily overlooked or neglected by individual companies. If you have your own software running on the cloud, you would, of course, have to update it yourself, but the underlying systems and infrastructure are typically kept up to date for you. 9. Deployment Speed Once the cloud system has been configured, it’s typically much faster and easier to deploy the system again, for example, to a different location or to set up a similar system by exporting the cloud configuration and applying it in subsequent deployment. The ease of this process, of course, depends on a particular cloud provider and service and can not always apply to cases of migrating from one provider to another, but a general deployment flexibility is still enhanced in many cases when using the cloud, and many providers advertise and pride themselves on such features. Existing Solutions for Cloud Internet of Things In order to be more practical, here are some examples of well-known services provided by popular cloud providers that can accommodate and work with IoT data: Amazon Web Services (AWS) AWS IoT Analytics: This AWS service is able to process, enrich (with metadata), store, and analyze large volumes of IoT data with the ability to query and visualize the results. Amazon Kinesis: Amazon Kinesis was developed to collect, process, and analyze real-time streaming data, enabling IoT applications to work with data as it arrives. Amazon Redshift: Redshift is a highly scalable data warehouse service that can be utilized for running sophisticated analytical queries on large volumes of IoT data. Google Cloud BigQuery: BigQuery is Google's serverless data warehouse that enables scalable analysis over massive amounts of data using SQL-like syntax. Dataflow: A stream and batch data processing service suitable for processing and analyzing IoT data in real time. Microsoft Azure Azure IoT Hub: Azure IoT Hub is a central message hub that facilitates communication between IoT applications and devices and allows for monitoring and control of your IoT infrastructure. Azure Stream Analytics: A real-time analytics service that can process vast amounts of streaming data rapidly flowing in from the IoT devices and more. Azure Data Lake Storage and Analytics: This service offers a scalable data store for handling large data volumes and running extensive analytics. Oracle Cloud Oracle IoT Cloud Service: This offering allows you to collect and analyze the data from your IoT devices in real time with the ability to integrate it with other Oracle services. Oracle Data Integration Platform Cloud: Assists in transforming, managing, and integrating data from various sources, including IoT devices, and provides analytics capabilities. This is, of course, not a complete list of possible offerings, and there are more options on the market to suit anyone’s needs. Challenges and Concerns When Integrating Cloud Computing With IoT Even when using a good and easy-to-use cloud solution, integrating your IoT network can prove to be a challenging task. Here are some general points to take note of when considering such an integration. Security Concerns Data Exposure When large amounts of data are being transferred from the end devices to the cloud, the risk of exposing sensitive data during transit increases. Mitigation: authentication and secure data transfer protocols have to be employed. Remember that clouds usually provide security mechanisms, but those still need to be explicitly used by the end users. For example, certificate or username-password-based authentication, MQTTS, etc. The typical process of configuring transport security and MQTTS usually involves generating certificates for your broker and applying them in configuration files (though, in some cases, depending on the broker of choice and the cloud provider, the steps might differ significantly). Vulnerable Devices If data is securely transferred and stored on the cloud, then the end IoT devices themselves might become the weakest link in the security chain, being potentially susceptible to attacks (and side-channel attacks in particular). Mitigation: Apart from the use of secure communication protocols, devices' firmware should be regularly updated and any unnecessary functions disabled. Additionally, regular security audits should be performed. Device Issues and Standardization Device Maintenance and Replacement Old IoT devices need to be replaced and regularly maintained. Failure to do so might lead to service disruptions, introduction of vulnerabilities, etc. Mitigation: use device management solutions that provide over-the-air updates and remote diagnostics to monitor the device's "health." Also, the logic of user applications and data processing solutions needs to account for potential device replacement downtimes. Standardization of IoT Devices Different IoT devices might use different protocols and data formats, which would make it hard to gather all the data into a single data store. Mitigation: Use open protocols and standards or gateway devices (and/or applications) that will translate device-specific protocols into open protocols (a typical industry standard would be to conform to MQTT protocol). Device Limitations Some IoT devices are too limited in their resources to support data formats or encryption techniques required by data processing solutions from the cloud. Mitigation: Again, make use of gateway/intermediary devices/applications that will aggregate and translate the data into appropriate format and/or use a required level of encryption. Latency Issues When using cloud solutions, data might arrive at the processing point a bit later than when compared to on-premise set-ups, especially if data centers for cloud computing are geographically very far from the IoT devices or if there are network disruptions. This might be a potential concern for time-critical IoT applications that require real-time data. However, in the real world, for most general applications, it is not such a common issue. Mitigation: Choose closer data centers and/or apply edge computing to decrease the volume of the data being sent, which will save some bandwidth. Other Concerns Other concerns include many less prominent and more obvious considerations, like the need to enable and properly set up the service’s autoscaling if scalability is needed or configuring backups, monitoring, and managing the data. All these concerns are usually addressed by the cloud providers, but it is typically up to the user to configure the provided solutions to suit the needs of their application. Hence, the most important thing to note is that even though clouds provide many features in regard to security, performance, and scalability, most of these have to be first properly and meaningfully configured to give the expected results. Apart from that, never forget that your physical devices also need to implement security and be regularly maintained. Summary In conclusion, combining IoT and cloud computing creates an unparalleled ecosystem where real-time data collection meets massive computational power, reshaping the fundamentals of how businesses operate and innovate. By interlinking the vast network of IoT devices with the expansive capabilities of the cloud, organizations get a lot of benefits. This allows for more innovative, data-driven decision-making and fosters a proactive approach to business challenges, including predictive analytics, automated responses, and AI-driven strategies.

AI holds significant promise for the IoT, but running these models on IoT semiconductors is challenging. These devices’ limited hardware makes running intelligent software locally difficult. Recent breakthroughs in neuromorphic computing (NC) could change that. Even outside the IoT, AI faces a scalability problem. Running larger, more complex algorithms with conventional computing consumes a lot of energy. The strain on power management semiconductors aside, this energy usage leads to sustainability and cost complications. For AI to sustain its current growth, tech companies must rethink their approach to computing itself. What Is Neuromorphic Computing? Neuromorphic computing models computer systems after the human brain. As neural networks teach software to think like humans, NC designs circuits to imitate human synapses and neurons. These biological systems are far more versatile and efficient than artificial “thinking” machines, so taking inspiration from them could lead to significant computing advancements. NC has been around as a concept for decades but has struggled to come to fruition. That may not be the case for long. Leading computing companies have come out with and refined several neuromorphic chips over the past few years. Another breakthrough came in August 2022, when researchers revealed a neuromorphic chip twice as energy efficient than previous models. These circuits typically store memory on the chip — or neuron — instead of connecting separate systems. Many also utilize analog memory to store more data in less space. NC is also parallel by design, letting all components operate simultaneously instead of processes moving from one point to another. How Neuromorphic Computing Could Change AI and IoT As this technology becomes more reliable and accessible, it could forever change the IoT semiconductor. This increased functionality would enable further improvements in AI, too. Here are a few of the most significant of these benefits. More Powerful AI Neuromorphic computing’s most obvious advantage is that it can handle much more complex tasks on smaller hardware. Conventional computing struggles to overcome the Von Neumann bottleneck — moving data between memory and processing locations slows it down. Since NC collocates memory and processing, it avoids this bottleneck. Recent neuromorphic chips are 4,000 times faster than the previous generation and have lower latencies than any conventional system. Consequently, they enable much more responsive AI. Near-real-time decision-making in applications like driverless vehicles and industrial robots would become viable. These AI systems could be as responsive and versatile as the human brain. The same hardware could process real-time responses in power management semiconductors and monitor for cyber threats in a connected energy grid. Robots could fill multiple roles as needed instead of being highly specialized. Lower Power Consumption NC also poses a solution to AI’s power problem. Like the human brain, NC is event-driven. Each specific neuron wakes in response to signals from others and can function independently. As a result, the only components using energy at any given point are those actually processing data. This segmentation, alongside the removal of the Von Neumann bottleneck, means NCs use far less energy while accomplishing more. On a large scale, that means computing giants can minimize their greenhouse gas emissions. On a smaller scale, it makes local AI computation possible on IoT semiconductors. Extensive Edge Networks The combination of higher processing power and lower power consumption is particularly beneficial for edge computing applications. Experts predict 75% of enterprise data processing will occur at the edge by 2025, but edge computing still faces several roadblocks. Neuromorphic computing promises a solution. Conventional IoT devices lack the processing capacity to run advanced applications in near-real-time locally. Network constraints further restrain that functionality. By making AI more accessible on smaller, less energy-hungry devices, NC overcomes that barrier. NC also supports the scalability the edge needs. Adding more neuromorphic chips increases these systems’ computing capacity without introducing energy or speed bottlenecks. As a result, it’s easier to implement a wider, more complex device network that can effectively function as a cohesive system. Increased Reliability NC could also make AI and IoT systems more reliable. These systems store information in multiple places instead of a centralized memory unit. If one neuron fails, the rest of the system can still function normally. This resilience complements other IoT hardware innovations to enable hardier edge computing networks. Thermoset composite plastics could prevent corrosion in the semiconductor, protecting the hardware, while NC ensures the software runs smoothly even if one component fails. These combined benefits expand the IoT’s potential use cases, bringing complex AI processes to even the most extreme environments. Edge computing systems in heavy industrial settings like construction sites or mines would become viable. Remaining Challenges in NC NC’s potential for IoT semiconductors and AI applications is impressive, but several obstacles remain. High costs and complexity are the most obvious. These brain-mimicking semiconductors are only effective with more recent, expensive memory and processing components. On top of introducing higher costs, these technologies’ newness means limited data on their efficacy in real-world applications. Additional testing and research will inevitably lead to breakthroughs past these obstacles, but that will take time. Most AI models today are also designed with conventional computing architectures in mind. Converting them for optimized use on a neuromorphic system could lower model accuracy and introduce additional costs. AI companies must develop NC-specific models to use this technology to its full potential. As with any AI application, neuromorphic computing may heighten ethical concerns. AI poses serious ethical challenges regarding bias, employment, cybersecurity, and privacy. If NC makes IoT semiconductors capable of running much more advanced AI, those risks become all the more threatening. Regulators and tech leaders must learn to navigate this moral landscape before deploying this new technology. Neuromorphic Computing Will Change the IoT Semiconductor Neuromorphic computing could alter the future of technology, from power management semiconductors to large-scale cloud data centers. It’d spur a wave of more accurate, versatile, reliable, and accessible AI, but those benefits come with equal challenges. NC will take more research and development before it’s ready for viable real-world use. However, its potential is undeniable. This technology will define the future of AI and the IoT. The question is when that will happen and how positive that impact will be.
