API Management Overview

API Management - the art of funnelling traffic from an API client through to the background service and taking care of things like authentication, rate-limiting, logging, auditing etc. 
 There are lots of solutions out there - both FOSS and commercial. 
 Google Solutions 
 Google have three solutions that they discuss on their cloud platform docs site ( mirror ): 
 
 ApiGee - looks like the super expensive enterprisey option not really an option for new products 
 API Gateway - seems to just provide a gateway that allows the internet to 
 Cloud Gateway - seems to be a really customisable/complex version of API Gateway 
 
 
 Seems like API Gateway might be useful if you are running cloud functions. Apigee is SOO SOO expensive - it starts at $700/month. 
 FOSS Solutions 
 Started exploring from this list ( mirror ) : 
 
 Looked at API Umbrella - it seems like they haven't; made any releases since 2019 and I'm not sure how maintained it is so staying away for now. 
 Started playing with Kong Gateway - it is lightweight, stores data in Postgres and looks easy to use with docker-compose.
