1. Advantages of Using RabbitMQ RabbitMQ offers several key benefits for distributed systems: Decoupling: System A no longer needs direct dependencies on System B and System C. When System D needs to be integrated, System A remains unchanged—the new system simply connects to the message queue. Async...
Synchronous vs. Asynchronous Communication Synchronous communication involves direct, immediate interaction, similar to a video call. Asynchronous communication involves delayed interaction, allowing a sender to communicate with multiple receivers without waiting, akin to texting. Pros and Cons of S...
