Microservices Stack

A microservices stack is a software architecture where applications are built as collections of smaller, independent services that communicate through APIs, messaging systems, or distributed workflows. By separating applications into independently deployable components, microservices architectures improve scalability, operational flexibility, fault isolation, and team autonomy. These architectures are commonly used for large SaaS platforms, cloud-native systems, ecommerce platforms, AI applications, realtime collaboration tools, enterprise software, financial systems, and other large-scale distributed environments.

Typical Architecture

A common microservices architecture looks like this:

Frontend Applications
          ↓
API Gateway
          ↓
Independent Services
          ↓
Distributed Databases + Queues
          ↓
Monitoring + Infrastructure Systems

Simple Architecture

A minimal microservices stack may include:

API Gateway
