The document discusses microservice architecture, explaining its advantages over monolithic architecture, which is often complex and unscalable. It outlines the characteristics of microservices, such as being small, focused, and loosely coupled, and highlights features like independent deployment and fault isolation. Additionally, it mentions companies that are adopting microservices for their applications.

Before Microservices – Monolithic Architecture
Monolithic Architecture is like a big container wherein all the software components of an application
are assembled together and tightly packaged
Database
Client Side UI
Server Side Application
HTTP Request

What Is Microservice Architecture?
Microservices, aka Microservice Architecture, is an architectural style that structures an application as a collection
of small autonomous services, modelled around a Business Domain
In Microservice Architecture, each service is self-contained and implements a single Business capability
