Microservices architecture is an architectural style in which the application is loosely coupled; it is divided into components based on business capability or domain, and scales independently without affecting other services or components of the application. This contrasts with the monolithic architecture, where a full application is deployed on a server or a Virtual Machine (VM) and scaling out is not a cost-effective or easy solution. For each scale-out operation, a new VM instance has to be cloned and the application needs to be deployed.
The following diagram shows the architecture of a monolithic application, where most of the functionality is isolated within a single process and scaling out to multiple servers requires the full deployment of the application on the other server:
The following is a representation of microservices architecture,...
