What are microservices?

Microservices are an architectural style of software development where an application is broken down into a set of small, independent services. Each microservice is responsible for a specific business function and interacts with others through well-defined APIs, most often over a network.

Main characteristics of microservices:

• Modularity: each service implements a separate functionality.
• Independence: services are developed, deployed, and scaled independently.
• Decentralization: data and logic are distributed among services.
• Resilience: failure of one service does not lead to the failure of the entire application.

Example: an online store can consist of microservices for product catalog, order management, payment, and notifications, each of which is developed and scaled independently.
