In this section, we will explore the different approaches to ensuring that a deployment will be resilient and have low latency when deployed. As with other IoT networks, ensuring that the configuration we have for our networks is optimal is of utmost importance. First, we will be looking at the different strategies for resilience in IoT deployments. Afterward, we will look at how we can design and architect for it and see how it’s put into practice through a case study.
Strategies for resilience
For a successful IoT deployment, resilience is paramount. Ensuring that systems remain operational, even in the face of challenges, demands a multifaceted approach. The following are six pivotal strategies, each playing a unique role in fortifying the robustness and efficiency of IoT systems. These components, when implemented meticulously, not only safeguard against potential disruptions but also enhance the overall performance, scalability, and cost-effectiveness of IoT deployments.
Multi-region deployment
This strategy focuses on deploying your IoT infrastructure across multiple regions to ensure that if one region becomes unavailable, the others will continue to function and provide service. This helps ensure high availability and low latency.
Message queues and streams
Message queues and streams help ensure that data is processed in a reliable and efficient way. This is tantamount to high-throughput IoT deployments where data is sent and received in large volumes.
Edge computing
Edge computing, which you are already familiar with, allows us to process the data closer to the source of the data. This helps to reduce latency and improve the performance of our IoT deployment. Using Greengrass for this as described previously, for example, helps a lot with this.
Autoscaling
Configuring autoscaling helps with scaling the number of resources based on the amount of demand, ensuring that there is always enough capacity to handle traffic and keeping latency low, all while saving costs.
Load balancing
Load balancing distributes the incoming traffic across multiple instances to ensure that no instance is overwhelmed and availability is maintained. Therefore, load testing is often done on different instances to test the maximum capacity they can handle and assign loads based on either manual work or through load balancing algorithms accordingly.
Cloud-native services
Using services such as AWS IoT Core, AWS IoT Greengrass, or AWS IoT Analytics can help improve the efficiency, scalability, and security of your IoT deployment.
Now that we have seen the different strategies, we can look at how we can put them into practice when designing and architecting our solutions.
Designing and architecting your solutions
Now, let’s discuss how you can design and architect your own use cases as part of AWS deployments for your IoT networks.
