Microservice vs Monolith Architecture

Mircoservice Architecture

Microservice architecture (better known as microservices) is an architectural style that gives structure to application as a collection of services.
-Benefits of Microservice

Enables each service to be created and developed independently by a team that is focused on that service.
It helps solve the problem of complexity by breaking down application into a much more manageable service. This makes it much faster to create and develop, which makes the application much easier to understand and manage.
It heavily reduces the barrier of adopting new technologies.
Microservices also enable each of the services to be scaled independently.

-Downsides of Microservices

Microservice architecture makes you have to choose and implement an inter-process communication mechanism.
Microservice has a partitioned database architecture.
It is much more complex in the case of monolithic web application.
It is more difficult to implement changes that span multiple services.
Microservices is much more complex to deploy.

Monolithic Architecture

Monolithic applications are designed to handle multiple related tasks. This is the traditional unified model for the design of a software program. It is self-contained, and the components of the program are interconnected and depend on each other rather than loosely coupled.

-Benefits of Monolithic Architecture

Simple to develop.
Easy to test.
Simply to deploy. All you have to do is copy the packages application to a server.
Simple to scale horizontally by running multiple copies behind a load balancer.

-Downsides of Monolithic Architecture

Has a limitation in size and complexity due to its simple approach.
This application is far too large and complex to fully understand and make changes with ease and efficiently. -You have to redeploy the entire application on each update.
Slow times for start-up.
Continuous deployment is difficult.
Can be be difficult to scale when different modules have conflicting resources requirements.
A barrier to adopt new technologies.
