Event-Driven Microservices & Micro Frontend Architecture
Designing Resilient, Scalable, and Real-Time Digital Platforms
The Legacy Architecture Challenge
Problem Statement
- • Tight interdependencies leading to fragile releases
- • Limited ability to scale specific features independently
- • Absence of real-time capabilities without costly polling
- • Bottlenecks between frontend and backend teams
Our Objective
Reimagine the digital foundation using event-driven architecture that empowers:
- • Independent delivery pipelines for services and modules
- • Bi-directional, real-time data flow using WebSockets
- • High fault tolerance with automatic retries
- • Polyglot technology stack flexibility
Architecture Overview
Microservices Layer
Domain-driven services built with NestJS, Spring Boot, Node.js, .NET, and FastAPI. Isolated data stores per service.
Process Manager
Implements Saga pattern for orchestrating long-running workflows with retries and compensating actions.
Channel Adaptor
Unified gateway for REST and real-time WebSocket traffic with Socket.IO for live updates.
Micro Frontends
Built with ReactJS, Angular, Flutter, Next.js, Vue.js. Independent deployments using Module Federation.

Impact Achieved
Measurable improvements across development and operations
| Metric | Before (Legacy Platform) | After (EDA Platform) |
|---|---|---|
| Feature Deployment Time | 2–3 weeks | < 3 days |
| Cross-Team Dependencies | High | Fully Decoupled |
| Real-Time Capability | Absent | Native via Socket.IO |
| UI & API Rollout | Monolithic | Per-Module Deployments |
| Failure Recovery | Manual | Automated Retry Logic |
