Application builds when broken down into multiple smaller service components, are known as microservices. When compared to the traditional Monolithic way, a Microservice Architecture treats each microservice as a standalone entity/module, essentially helping to ease the maintenance of its code and related infrastructure. Each microservice of an application can be written in a different technology stack, and further be deployed, optimized and managed independently.
Though in theory, a Microservice Architecture specifically benefits build of complex large-scale applications, however, it is also widely used for small-scale application builds (for example, a simple shopping cart) - with an eye to scale further.
A modern cloud-native application running on Microservice Architecture relies on the following critical components:
The above three are the most important components of a microservice architecture that allow applications in a cloud-native stack to scale under load and perform even during partial failures of the cloud environment.
