Build a Microservice Architecture with NestJS

NestJS simplifies building microservice architectures by breaking large applications into smaller, independent services. Key advantages include improved scalability, faster development, fault isolation, and technology flexibility. The article demonstrates creating simple Math and String microservices using NestJS, along with a client application to communicate with them. Best practices for microservices include focusing on small, independent services, maintaining loose coupling, and using an API gateway. NestJS's built-in support for various communication protocols facilitates creating powerful distributed systems.
