Microservices architecture is an approach to software development that structures an application as a collection of small, independent services that communicate with each other through APIs. Microservices architecture aims to improve scalability, resilience, and flexibility of software systems, by reducing complexity and allowing for independent deployment and scaling of services. Popular microservices frameworks include Spring Boot, Micronaut, and Quarkus.
