1. Microservices Architecture
- Based on loosely coupled services.
- Each service is in its own process.
- Lightweight communication protocols.
- Polyglot – no platform dependency between services.
Replaces 2 legacy architectures as Monolith and SOA (Service Oriented Architecture).
The most important part in the EDA is the microservices communication. Which is dictated performance, and scalability. So the Event Driven Architecture handles the communication part.
