Microservices

Microservices are architectural style in which large & complex software applications are composed of one or more smaller services.

Microservices are design principles for an application

Four main characteristics:

1. Loosely Coupled: The microservices are not tightly dependent on each other
2. Small & Focused: Each microservice focus on smaller & single task
3. Language Neutral: One microservice can be written in JAVA for performance benefits and other in Python for quicker deployment
