What are microservices, and how do they differ from monolithic

Short answer: rchitectures? Microservices are an architectural approach where an application is divided into small, independently deployable services, each focused on a specific business function. These services communicate with each other over APIs and are developed, deployed, and scaled independently. Monolithic architectures, in contrast, bundle all… components of… an…… application into a single, tightly coupled unit. Changes…

Explain a bit more

or scaling require the entire application to be redeployed. Key Differences: Microservices offer modularity, scalability, and independent deployment, while monolithic is a single, tightly integrated system that can be harder to scale and maintain as it grows.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.
