Building RESTful Web services with Go

Using an API Gateway to Monitor and Metricize REST API

Once we have developed our API, we need to expose it to the outside world. In that journey, we deploy them. But is that sufficient? Don't we need to track our API? Which clients are connecting? What is the latency of requests, and so on and so forth? There are many other post-API development steps that one should follow to make their API production grade. They are authentication, logging, rate limiting, and so on. The best way to add those features is to use an API gateway. In this chapter, we will explore an open-source API gateway called Kong. Open-source software is preferable to cloud providers because of the reduced risk of vendor lock. All the API gateways differ in the implementation ...
