Following my post, I decided to take on an action and learn Go.

As everyone told me it was an easy task and since then I have already deployed two Go services to production on Kubernetes.

Here are my thoughts, bare with me and let me know what you think:

Pros

  • Very easy to learn
  • Lightweight (memory & footprint)
  • High performance
  • Implementation is pretty straightforward
  • Typed language

Cons

GOPATH

Tips

  • Use alpine or even scratch as a base docker image (my docker image is only 10MB )
  • Make sure to use circuit breakers and timeouts for every third party call (external services, database, etc...). My favorite is afex/hystrix-go , I also tried sony/gobreaker but it has some performance overhead.
  • Use uber-go/automaxprocs for automatically setting GOMAXPROCS according to the resources quota of Kubernetes
  • To mock functions declare them as variables
  • I use the builtin net/http router, usually it is more than enough for a simple microservice

Currently I am having fun writing Go and feeling confident with the outcome. I will keep it going for a while and see how it goes :stuck_out_tongue_winking_eye:
