Microservices architecture has emerged as a popular solution for building complex and scalable applications. In a microservices architecture, an application is broken down into a collection of loosely coupled, independently deployable services that communicate with each other via APIs. This approach offers many benefits, including improved scalability, reliability, and flexibility.
However, managing the APIs in a microservices architecture can be challenging, especially as the number of services grows. This is where API versioning comes in. API versioning is the practice of creating multiple versions of an API to support different clients and use cases. It helps ensure that changes to an API don't break existing clients and provides a way to evolve the API over time.
