How to design & develop REST microservices in Golang (Go)
In this second part of the series I'm working with MySQL, Cassandra and Elasticsearch as persistence layers and we're going to create 3 different microservices using different design patterns: MVC, featured MVC and Domain Driven Development implementing the Hexagonal architecture.
