API Gateway Cache With Kong's Proxy Cache Plugin
In applications built on a system of microservices, developers should always be on the lookout for opportunities to eliminate unnecessary use of resources, such as database queries, network hops or service requests. API gateway cache (or response caching) is an excellent place to start. For many microservices, identical requests sent within a window of time will yield identical responses. For example, consider a request to an Orders API for the list of orders submitted yesterday.
