This post introduces building microservices using Python and Couchbase, providing a fully scalable solution. Microservices architecture splits application components into small, independently scaled pieces that serve one functional area of the overall application. A good microservice should be lightweight, stateless, and designed for failure, with APIs such as RESTful interfaces working well in this environment. Couchbase is used to store user profile data due to its performance, scalability, and ease of use. Python is chosen as the programming language due to its accessibility, ease of learning, and scalability with multiprocessing. A sample application walkthrough demonstrates how to create a simple RESTful interface using Python and Couchbase, showcasing the concept of microservices architecture in practice.
