SOA is designed to enable the development of software that can be reused across different applications or services. In SOA, services are self-contained units that can be accessed remotely over a network. These services can communicate using standard messaging protocols, which makes them highly interoperable, even if they are built on different technologies or programming languages. SOA emphasizes the integration of various applications and systems, promoting organizational agility and simplified system updates. It supports education of distributed systems by promoting loose coupling between components, which makes the systems easier to develop and manage over time.
