AWS Messaging

This lesson is part of AWS · All levels

Summary

Messaging and queuing allow application components to communicate with each other without being directly dependent on each other. With cross-service messaging, the system becomes more resilient to traffic surges because the processor can work at its own speed. This approach became the foundation of distributed architecture and cloud microservices.

Key points

Decoupling separates the sender and the receiver
Queue holds messages until processed
Communication makes the sender not wait for a reply
Buffer messages absorb the sudden surge in demand
