What are Microservices?

Microservices represent a modern approach to software architecture that emphasizes breaking down an application into smaller, independent services. Each service focuses on a specific business function and operates separately. Unlike traditional monolithic applications, which tightly integrate all functionalities into a single large codebase, microservices are modular and loosely coupled, allowing them to be developed, deployed, and scaled independently.

Why Use Microservices with ASP.NET Core?

ASP.NET Core is a robust, high-performance framework ideal for building microservices. Here’s why:

• High Performance: ASP.NET Core is known for its speed and performance, making it ideal for building scalable microservices.
• Cross-Platform Support: ASP.NET Core is cross-platform, which allows us to develop and deploy microservices on Windows, Linux, or macOS.
• Modern Development Practices: ASP.NET Core uses Model Features such as dependency injection, middleware, and other features essential for microservices architecture.
• Containerization Support: Easily integrate with other technologies and frameworks, including Docker and Kubernetes.
• Security: Built-in features for authentication and authorization ensure your microservices are secure.
• Modular and Lightweight: ASP.NET Core’s modular architecture ensures that you only include the necessary components, keeping your services lightweight.
