We all have been always listening about the different architecture we have. Some of the famous architecture are
Monolythic
Micro service
Monolith means composed all in one piece like a sandwich. The Monolithic application describes a single-tiered software application in which different components combined into a single program from a single platform. Components can be:
Authorization layer
Presentation layer
Business logic
Database layer
Third party integration
Notification layer
UI layer

Let’s take example of a e-commerce website
Browser
mobile ——> Application layer —————> RDMS
Pros :
Easy to develop
Easy to test
Easy to deploy
Easy to scale horizontally
Cons :
Maintenance
Redeploy for any fix
Reliability
Microservice Architecture
Microservices is an approach to application development in which a large application is built as a suite of modular services (i.e. loosely coupled modules/components). Each module supports a specific goal and uses a simple, well-defined interface to communicate with other sets of services.
Instead of sharing a single database as in Monolithic application, each microservice has its own database. Having a database per service is essential if you want to benefit from microservices, because it ensures loose coupling. Each of the services has its own database. Moreover, a service can use a type of database that is best suited to its needs.
Example
Payment service
Balance service
Coupon service
Shipping service
Pros
Better testing
Betting deployment
Easy to introduce any new technology
Easy to understand
Cons
Testing is more difficult
Deployment complexity increases
Debugging complexity increases
