A message queue allows different services to communicate asynchronously. Instead of waiting for another service to finish, a service places a message into a queue, and another service processes it later. Example ↓ Order Service ↓ Message Queue ↓ Email Service The user receives an immediate response while the email is sent in the background. Benefits |
