What is Microservices?

Microservices describes an architectural paradigm in software engineering where applications are structured as a suite of small, independently deployable services. Each service typically performs a distinct business function and communicates with others via lightweight protocols, such as HTTP or messaging queues. This modular approach contrasts with traditional monolithic architectures, offering greater flexibility, resilience, and scalability. As organizations seek to deliver features to market more efficiently, many opt for microservices to facilitate continuous delivery and rapid iteration. By decoupling components, teams can develop, deploy, and scale services independently, minimizing interdependencies and reducing risks associated with system-wide changes. According to industry resources, this approach is especially appealing for complex applications with evolving requirements. The adoption of microservices is also closely linked to the use of containerization and orchestration tools, which streamline deployment and management. For those interested in distributed system concepts, exploring service discovery mechanisms provides deeper insight into how microservices coordinate efficiently.
