Summary

In this chapter, you got a close look at the Go kit toolkit, the overall Delinkcious system and its microservices, and got to drill down into the social graph component of Delinkcious. The main theme of this chapter is that Go kit provides clean abstractions, such as services, endpoints and transports, and generic functionality for breaking microservices into layers. Then, you add your code for a consistent system of loosely-coupled yet cohesive microservices. You also followed the path of a request from the client, all the way to the service and back through all the layers. At this point, you should have a general grasp of how Go kit helps shape the Delinkcious architecture and how it would benefit any other system. You may be a little overwhelmed by all of this information, but remember that the complexity it neatly packaged and that you can ignore it most of the time, focus on your application, and just reap the benefits.

In the next chapter, we'll address a very critical part of any modern microservices-based system – the CI/CD pipeline. We'll create a Kubernetes cluster, configure CircleCI, deploy the Argo CD continuous delivery solution, and see how to deploy Delinkcious on Kubernetes.
