VM image update notification mechanism based on pub/sub paradigm in cloud
Virtual machine image encapsulates the whole software stack including operating system,middleware,user application and other software products.Failure occurred in any layer of the software stack will be treated as image failure.However,virtual machine image with potential failures can be convert to template and spread to a wide range by means of template replication.And this paper refer to this phenomenon as “image failure propagation.Usually,patching is a widely adopted solution to resolve software failures.Nevertheless,virtual machine image patches are difficult to deliver to the final users in cloud computing environment for its openness and multi-tenancy features.This paper described image failure propagation model for the first time and proposed a promoting mechanism based on pub/sub computing paradigm to combat with the patching delivery problem.
