Microservices is an architectural style that structures an application as a collection of loosely coupled, independently deployable, and small services.

Each service in a microservices architecture runs a specific business capability, such as user management, product catalog, or payment processing, and communicates with other services through a well-defined interface, typically using APIs.

This approach offers several benefits, including:

• Improved scalability, as each service can be deployed and scaled independently
• Better fault tolerance, as the failure of one service does not affect the overall system
• Improved deployment frequency, as services can be deployed and updated independently
• Improved resource utilization, as services can be developed in different languages or technology stacks to best suit their specific needs.

Microservices architecture is commonly used in cloud-based applications, where the flexible and scalable nature of the architecture is well-suited to the dynamic and constantly evolving needs of modern software applications.
