Some architects, cloud engineers, and DevOps folks often say, “Microservices are small monoliths.” This stems from the complexity of dealing with a number of services, especially managing and configuring their network rules and security aspects.
When clients make requests to microservices spread over multiple clusters and clouds in a distributed system, tracking each request to ensure security and proper routing rules becomes tedious. Ideally, backend services should not be doing that, as they should be left alone with delivering the business logic. This is where an API gateway, a single entry point for all requests, comes in. Let us see what an API gateway is and what features and benefits it offers.
