What is SOA/Microservices?

SOA (Service-Oriented Architecture) is an architectural style that structures an application as a collection of loosely coupled services. These services communicate with each other, often over a network, using well-defined interfaces, typically web services. SOA promotes reusability, flexibility, and interoperability. It is commonly used in enterprise-level systems to integrate different applications and business processes. Microservices, on the other hand, is an architectural approach that structures an application as a collection of small, autonomous services, modeled around a business domain. Each microservice is independently deployable, scalable, and can be developed using different technologies. Microservices are often used to build complex applications that require high availability, scalability, and rapid development cycles. While SOA focuses on service reusability and integration, microservices prioritize autonomy and independent deployment.
