Writing web services in Go is terrific! The language is natively compiled and therefore is wicked fast; concurrency is a first class language feature in Go; and there are mature web service frameworks in Go. One of those webservice frameworks in Goa. It is a design first web services framework that generates most of the glue and scaffolding needed to run services in Go for you and lets you concentrate on the business logic.
AWS Serverless Technology
I ended up developing what I call the AWS API to Lambda Shim. The ReadMe describes in great detail how to use it to server up a simple API so I will not repeat that here. However, the possibilities here are amazing. Go has such a quick startup time that even with no “warming”, the service returns in milliseconds. Once warmed, I expect performance to be quite good. I will be conducting some stress testing on this in the future and I promise to report the results here. The lambda function can backup any number of API endpoints. Amazon maintains a very robust Go implementation of their API allowing the Go based Lambda functions to perform a myriad of functions in the AWS ecosystem.
