A major advantage of cloud computing and storage is the large-scale sharing of resources, which provides scalability and flexibility. But resource-sharing causes variability in the latency experienced by the user, due to several factors such as virtualization, server outages, network congestion etc . This problem is further aggravated when a job consists of several parallel tasks, because the task run on the slowest machine becomes the latency bottleneck.
