Building Scalable Microservices for Enterprise Applications

Introduction

Microservices and their significance in enterprise applications

Microservices are a software architectural style that structures an application as a collection of small, independent services.

Each service runs independently and communicates through well-defined APIs.

This structure enhances modularity, making it easier to develop, manage, and scale applications in enterprise environments.

Microservices have emerged as a response to the limitations of monolithic architectures.

In earlier software designs, companies faced challenges in scaling and maintaining large codebases.

As user demands grew, organizations struggled to deliver updates quickly.

This led to slower response times, reduced reliability, and higher operational costs.
