Microservices Design Patterns in .NET - Second Edition
By :
In this chapter, we dove deep into the critical role of API gateways and the BFF pattern in modern microservices architectures. First, we revisited why building a microservices application can quickly become overwhelming, with clients needing to track multiple API endpoints. To address this, we can introduce an API gateway to simplify client interaction by exposing a single, unified API while handling complex backend orchestration, security, logging, and aggregation concerns.
We explored what an API gateway is and that it does more than just route traffic. It can centralize cross-cutting concerns, such as authentication, rate limiting, caching, monitoring, and service discovery. This makes the client app much simpler and more maintainable because it only needs to interact with one gateway, rather than needing to know the details of every microservice.
As helpful as API gateways are, they aren’t a silver bullet. If they aren’t properly designed for redundancy...
