Queues

• Queues are used to effectively manage requests in a large-scale distributed system, in which different components of the system may need to work in an asynchronous way.
• It is an abstraction between the client’s request and the actual work performed to service it.
• Queues are implemente on the asynchronious communication protocol. When a client submits a task to a queue they are no longer required to wait for the results
• Queue can provide protection from service outages and failures.
