The Kubernetes, an open-source container orchestration platform, allows us to deploy the containerized microservice application in public, private, or hybrid cloud infrastructure.
A microservice is built around business capability and DDD provides a framework for building microservices around business capabilities. Likewise, Event storming is a workshop-style, lightweight DDD framework. This article explains a recipe for building a microservice application using Spring Boot, DDD, Event Storming, and API-first design.
An API Gateway or Backend for frontend (BFF) is an important design pattern for building applications based on microservices architecture. This reduces chattiness between clients and services by aggregating multiple requests into a single request. We can build specialized BFF services(s) to handle different interfaces for browser and mobile applications. The API Gateway can also be used to offload cross-cutting concerns such as authentication, authorization, rate limiting to a proxy.
