Provide a flexible, scalable, and cost-effective way to develop distributed applications

Web services are software components that can be accessed over the internet using standard protocols and formats. They enable interoperability and integration among different applications and systems. Web services design and development involves defining the functionality, interface, and quality of service of the web service, as well as implementing, testing, and deploying it. Enterprise Service Bus (ESB) is a middleware technology that facilitates communication and coordination among web services and other components in a distributed architecture. ESB provides features such as routing, transformation, mediation, orchestration, security, and monitoring of web service interactions.
