Queue-based load leveling pattern

Cloud applications may sometimes be subjected to heavy loads (user and data). Applications are being designed and developed accordingly and are made to run on clustered environments in order to meet sudden or seasonal spikes. When applications are under heavy loads, the application performance may go down. Especially, some crucial tasks that are the part of the application may come under heavy bombardment.

The viable approach is to refactor the application and introduce a queue between the task and the service. The idea here is that the task and the service run asynchronously. The task posts a message containing the data required by the service to a queue. The queue acts as a buffer, storing the message until ...
