Microservices is a software architecture in which an application is divided into a collection of small, independent services, with each service responsible for a specific business function. Instead of building and deploying the entire application as one large system, individual services can be developed, updated, scaled, and maintained independently while communicating with one another through well-defined interfaces.
For example, an e-commerce platform might use separate services for customer accounts, product catalogs, payments, inventory, and order processing. If the inventory service needs additional computing resources during a period of high demand, it can be scaled without scaling the entire application. Microservices can improve development flexibility, scalability, fault isolation, and deployment speed, making the architecture particularly useful for large, continuously evolving applications and cloud-native systems.
