Monolithic

-means we are developing every functionality will sit in one application.

-single point of failure

-tight coupling

-centralized network

Microservices:

-here we develop our project by breaking into multiple applications i.e is microservices.

-Fault tolerance

-loosely coupling

-decentralized network

-high cohesion

-observability

when to use?

Monolithic -if we care about budget, project has small features. and project size is small.

Microservice-here budget is more, and complexity is more, designing microservice is a Challege. and if we have many requests then we need scaling and Microservices allow for better scalability, fault isolation, and flexibility in development and deployment.
