That's it for this chapter, we have just written our first microservice in Go and only using the standard library, you should now have an appreciation of just how powerful the standard library is providing us with many of the features we need to write RESTful and RPC-based microservices. We have also looked at encoding and decoding data using the encoding/json package and how we can create light weight messaging by using gobs.
As you progress through this book, you will see how the many, wonderful open source packages build on these foundations to make Go such a fantastic language for microservice development, and by the end of the book you will have all the knowledge required for successfully building microservices in Go.
