Both Micro and gRPC came out on top in the evaluation, but for slightly different reasons. Micro is ready to use in a production system out of the box if the majority of your estate is Go. The development on Micro is continuing, and the current focus is on that of performance, which, to be honest, is already pretty impressive. That said, with some work around the missing elements that are essential for microservice development, gRPC is a real contender. The polyglot nature and the throughput are excellent, and it is continuously improving.
In this chapter, we have looked at a few different frameworks, and I hope they will have given you a taster of some of the key features needed if you ever have to make a decision yourself. In the next chapter, we are going to look at logging and metrics, which are essential techniques for running microservices in production.
