What is Web Service?
Web Service is a way to expose the functionality of an application to other application, without a user interface. It is a service which exposes an API over HTTP.
Web Services allow software applications developed in different technologies to communicate with each other through a common format like XML, Jason, etc. Web services are not tied to any one operating system , programming languages or user device software platforms. For example, an application developed in Java can communicate with the one developed in C#, Android, etc., and vice versa.
Web Service is a connection technology, a way to connect other services together into a Service Oriented Architecture (SOA) and also represents web application’s functionality.
There are mainly two types of web services – SOAP (Simple Object Access Protocol and REST (Representational State Transfer).
What is Microservice?
Microservice architecture is an independently deployable service modeled around a business domain having its own database. It is a method of breaking large software applications into loosely coupled modules, in which each service runs a unique process and communicates through APIs. It can be developed using messaging or event-driven APIs, or using non-HTTP backed RPC mechanisms.
Microservices are designed to cope with failure and breakdowns of large applications. Since multiple unique services are communicating together, it may happen that a particular service fails, but the overall larger applications remain unaffected by the failure of a single module. For ERP, CRM, automobile, banking and other financial services Microservices is the most suitable architecture.

Why use Microservices and Web Services?
Web services support modules and feature independence, but microservices support independence at nearly all levels, including server instance, application, module, feature, and function. The more your independence, the easier it is to expand an application’s functional capabilities and give service to a wider user base.
Why use Web Services?
Web services enable independence from monolithic programmes with no additional expense in terms of server instances, as the same number will be required. Although the time required to create apps using a web services architecture is little and adds expense to the project, it is worth the effort because every application will require minor modifications and fixes in the future. The web services enable you to expand the functionality of individual application modules without affecting the operation of other modules.

Why use Microservices?
Microservices give greater freedom than web services but at the expense of development and maintenance. Microservices is an architectural style that enables you to scale the functional capabilities of your application and the user base it can support indefinitely. While microservices may operate on many server instances and utilise cross-region replication to minimise application latency, this software architecture also aids in disaster recovery management and load balancing by directing requests to replicas in different geographical areas.
