What are Microservices?

Microservices is an architectural style in which an application is structured as a collection of loosely coupled, independently deployable services. Each service is responsible for a specific business capability and communicates with others through well-defined APIs. This architecture enables greater flexibility, scalability, and maintainability compared to traditional monolithic systems.

Why Use Microservices with ASP.NET Core Web API?

ASP.NET Core is a modern, high-performance, cross-platform framework ideally suited for building microservices due to its:

• Cross-Platform Support: Deploy on Windows, Linux, or macOS
• Modern Development Features: Built-in dependency injection, middleware, minimal APIs, etc.
• Container-Friendly: Excellent compatibility with Docker and container orchestration tools.
• High Performance: Optimized for speed and efficiency.
• Modular Architecture: Use only what you need to keep microservices lightweight
