A queue is a container of messages.
Queues are optimized to contain small numbers of messages that flow through the queue before reaching their destination.
By placing a queue between the producer of the message and the consumer, the
Producer can send a message without knowing whether the customer of the message is currently available, and this type of scenario is called as “asynchronous communication”.
With the synchronous communication, where the producer must wait for the customer to
become available and complete processing on the message before being able to continue.
