Microserviciu

Microserviciu is an architectural style that structures an application as a collection of small, autonomous services, each running in its own process and communicating with lightweight mechanisms. This approach contrasts with the traditional monolithic architecture, where an entire application is built as a single, unified unit.

Each microserviciu is designed around a specific business capability. This means that a single service is responsible for one distinct function or domain within the larger application. For example, in an e-commerce application, you might have separate microserviciu for user management, product catalog, order processing, and payment handling.

Key characteristics of microserviciu architecture include independent deployability, technology diversity, and resilience. Because services are independent, they can be developed, deployed, and scaled individually without affecting other parts of the application. This allows teams to use different programming languages, databases, and tools best suited for their specific service. If one microserviciu fails, it ideally should not bring down the entire application, as other services can continue to function.

Communication between microserviciu typically occurs over a network, often using lightweight protocols like HTTP/REST or message queues. This distributed nature introduces complexities in managing inter-service communication, distributed transactions, and overall system observability. However, the benefits of agility, scalability, and resilience often outweigh these challenges for many modern applications.
