Micro Apps vs Microservices: What’s the Difference?

While micro apps and microservices are both architectural approaches to building complex systems, they serve different purposes and operate at different levels.

Micro apps have the following characteristics:

• Focus: User interface and user experience
• Purpose: To break down large, complex applications into smaller, focused applications that perform specific tasks
• Technology: Often built using web technologies like React, Angular, or Vue.js
• Example: A micro app for approving expense reports within an ERP system

On the other hand, microservices serve the following goals:

• Focus: Backend services and system architecture
• Purpose: To break down large, monolithic applications into smaller, independent services that can be developed, deployed, and scaled independently
• Technology: Often built using languages like Java, Python, or Node.js
• Example: A microservice for handling product catalog data within an e-commerce platform

The table below lays down the key differences in simple words:

Feature	Micro Apps	Microservices
