When building a microservices system, configuring events to trigger additional logic using an event stream is highly valuable. One common use case is receiving notifications when errors are seen in one of your APIs. Ideally, when errors occur at a specific rate or frequency, you want your system to detect that and send your DevOps team a notification. Since AWS APIs often use stateless functions like Lambdas, you need to include a tracking mechanism to send these notifications manually.

In modern cloud architecture applications are broken down into independent building blocks usually as microservices. These microservices allow teams to be more agile and deploy faster. Microservices form distributed systems in which communication between them is critical in order to create the unified system. A good practice for such communication is to implement an event-driven architecture.

Microservices are the future of software development. This approach serves as a server-side solution to development where services remain connected but work independently from each other. More developers are using microservices to improve performance, precision, and productivity, and analytical tools provide them with valuable insights about performance and service levels.

In this article, we are going to look at Microservice architectures, their benefits, what makes them different from traditional monolithic architectures, and how to go about setting up monitoring and alerting for them. MetricFire is a Hosted Graphite, Grafana, and Prometheus service, where we help you set up and manage these open-source tools.

When it comes to conversations around application architecture or working with integrations between applications, you’ve likely heard a couple terms pop up a few times: microservice and APIs. You might also have run across the common misconception that microservices are just a way to implement APIs so they can communicate with each other. As you’ll see in this article, there are alternative ways to architect our microservice applications.
