Microservices
Microservices is an architectural style that structures an application as a collection of loosely coupled, independently deployable services, each focused on a specific business capability. It enables teams to develop, test, and scale components separately, often using lightweight communication protocols like HTTP/REST or messaging queues. This approach contrasts with monolithic architectures, promoting agility, resilience, and technology diversity in large-scale systems.
Developers should learn microservices when building complex, scalable applications that require frequent updates, high availability, or team autonomy, such as e-commerce platforms, streaming services, or enterprise SaaS products. It's particularly useful for organizations adopting DevOps practices, as it facilitates continuous delivery and independent scaling of components based on demand, reducing bottlenecks and improving fault isolation.
