This is it.
You’ve perfected the hardware solution for your IoT product. You’ve implemented best practice provisioning mechanisms to secure your product network. A team of web and mobile developers have created and tested an application that you’ve deemed miraculous.
Now all that is left is to launch your product and let your users marvel in your creation. Everything seems to be going great. As you monitor systems status you slowly start realizing that your users are experiencing long load times, and even worse, application outage.
Oh no! How could this be? You’ve done everything right up until this point.
If the experience described above sounds familiar, don’t worry; this is a sign of growing pains that your application is experiencing. Most IoT designs demand a heavy read load on backends in order to populate an application with useful information for end users such as status, alerts, charts, graphs, revenue, etc.
The good news is that there is a simple and economical solution to this problem. Before you make a knee jerk reaction that may cost you big time in the end read on to learn about the benefits of read replicas.
Read replicas are copies of master database instances and are commonly used to read requests or analytics traffic from the master. You can create multiple read replicas for a single master instance.
The illustration below provides an example of how a read replica would integrate into an existing IoT network infrastructure.
Creating a read replica is one of the many common practices to improve performance for your IoT application. Performance gains stem from distributing read and write operations across multiple machines. Most common cloud services offer a streamlined way of implementing read replicas and it is a useful technique to service read intensive applications.
