Essential communication patterns

When building microservices, we mostly need a single point of entry for our clients to consume the services that we develop. You may think about it like a decorator or wrapper over your services. Clients talk to your app through a simple door (API gateway) instead of needing to know the messy inner workings (microservices). The gateway intelligently routes incoming requests to the appropriate microservices based on factors such as URL patterns, path variables, or headers.

An important component of microservice architecture is an API gateway. This API offers several features to help manage and expose common functionalities across multiple microservices. Often, a client request might require data from multiple microservices. The gateway acts as an orchestrator, fetching data from relevant services, aggregating it (if necessary), and returning a cohesive response to the client. In short, API gateways are essential components of microservice architecture...
