What is a microservice?

Microservices are modular, loosely-coupled services that provide a fine-grained protocol. They physically separate concerns and allow us to design, develop, test, and deploy them independently.

Due to their modular capabilities, they can be created by small cross-functional teams that are embracing the benefits of agile methodologies and the DevOps culture. They are also an ideal candidate for continuous delivery and deployment.

They are easy to understand and connect well with other services, making integration of complex applications a lightweight task. They can be scaled, monitored, and controlled independently so that they fully benefit cloud architectures.
