Design Microservices Architecture with Patterns and Principles - Single-Receiver Message-Based Communication (One-to-One

The video tutorial explains message-based communication, focusing on 1-to-1 queue or point-to-point communication. It highlights the use of asynchronous communication for long operations, using a single producer and receiver. The command pattern is used as an example, where a queue object executes commands with incoming messages. A practical use case is the create order command in microservices, where the order creation process is delayed. Messaging queues ensure message reliability, holding messages until the receiver is ready. Common systems include Revit MQ, Active MQ, and Amazon QS.

What is the primary purpose of one-to-one queue communication?

Explain the command pattern in the context of one-to-one queue implementation.

What happens to a message in a point-to-point system after it successfully reaches the consumer?

Describe the behavior of the message queue when the target service is down.

List some common use cases of queuing systems mentioned in the text.
