Web services utilizes a standardized medium to propagate communication between a client and server application on the world wide web. Web services are software modules designed to perform a certain task. Web services provides common platform that allows applications built with different programming languages to communicate with each other. There are 2 types of web services including SOAP web services and RESTFul web service.

It invokes services by calling the RPC method; and doesn’t return human readable result. Transfer is mainly over HTTP , the standard web protocol as well as SMTP/FTP protocols SOAP performance is not as great as REST.
Microservices is a service-oriented architecture construct where applications are built as a collection of independent service units. It is a software engineering approach that uses decomposing to bring an application in to a single functional module. There are several tools that can be used to provide Microservices such as Docker, Hystrix, and Wiremock. A distributed system, it is inherently complex model that requires effective management and teamwork to deliver a perfect result.
