In the GoLang we use interfaces everywhere. But we also should understand the rules and idioms how GoLang interfaces works. Let’s read about them 😉; part one:

Everybody use dependencies and third-party packages but what is the best way to use it? GopherAcademy helps to understand best practice for the vendor folder organization. Of course, code examples and theory points are included 🙂

Interesting step-by-step guide about design and development API with Docker containers, Swarm cluster and Traefik (HTTP reverse proxy and load balancer).

In this article you’ll know how to configure the Traefik in the Docker environment with 3 following nodes: one manager and two workers

https://nil.csail.mit.edu/6.824/2016/notes/gomem.pdf

Here is a must-read article about memory management in the GoLang about the following important points:
- stack, heap and the data segment explanation;
- escape analysis;
- garbage collector;
And good performance optimization advices 😉

Great article about the architecture inside of Golang microservice, based on the Bob's Clean Architecture Concept (https://8thlight.com/blog/uncle-bob/2012/08/13/the-clean-architecture.html)

Main points: Your GoLang microservice has 4 layers:
- Models, data structures, and their methods;
- Repository, the provider of DB operations and data management,
- Usecase for business logic implementation;
- Delivery, protocol, and algorithms for message handling (HTTP, gRPC, etc).

Each layer should be independent and be available for mocking, for internal communications between application layers.

An example project here: https://github.com/bxcodec/go-clean-arch
