The idea to apply circuit breaker pattern is to give protection and control over latency and failure, in order to stop cascading failure in a distributed environment. In addition, it provides a fail fast and rapid recovery for our services.
In a environment where number of instances and network locations changes dynamically, a client needs a discovery mechanism to determine the location of a service instance, in order to send a request to it.
API monitoring is essential because APIs are the only interaction mechanism between your services and outside world.

Logging means nothing if you cannot collect and analyze it.
Every application needs logging. Logging is very important, so you can consider it as a first class citizen. Therefore, application cannot be deployed to production without logging implementation.
This article will show how to create micro-services using Golang programming language and Go-kit as its framework. The service will be exposed via gRPC protocol.
In this article, I will create a simple micro-service using Go programming language and go-kit as a standard micro-services library. The service will be exposed via REST endpoint.
