In web services, the Enterprise Service Bus can fail as a single point and impact an entire system.

Communication
Every service is communicating through the ESB, therefore if a service slows down, it could build up traffic requests for that service.

Microservices, on the other hand, have lower errors. It could manage a memory fault better because only the microservice with a fault will be affected. Every other microservices will function continually, handling requests.

4. Function
Microservices are a self-sustained group of china mobile database small applications developed to solve problems for large systems. System implementation is facilitated by dividing it into small modules for better understanding and development of the software. These small modules can be worked on, tested, and deployed independently.

A WS supports the easy integration of applications more than before its existence. It slashes the cost of doing e-businesses transactions by the facilitation of direct application-to-application interaction using internet standards and protocols.

5. Structure
Microservices are an architectural style built usually for business capabilities. At the same time, it can be integrated into a web service. Nevertheless, microservices can be a stand-alone service or a function that has its own database and can be implemented and deployed independently of other services.

A web service is a service provided from one application to another through the World Wide Web. As an API representation through HTTP, it is an abstraction layer that separates between a platform and the specific programming details of how the application code is really called to function.
