TCC : A Novel Cloud Service for Cloud-deployed Applications

Applications with a dynamic workload demand need access to a flexible infrastructure to meet performance guarantees and minimize resource costs. While cloud computing provides the elasticity to scale the infrastructure on demand, cloud service providers lack control and visibility of user space applications, making it difficult to accurately scale the infrastructure. Thus, the burden of scaling falls on the user. That is, the user must determine when to trigger scaling and how much to scale. Scaling becomes even more challenging when applications exhibit dynamic changes in their behavior. In this paper, we propose a new cloud service, Trusty Compute Cloud (TCC), which spontaneously scales the infrastructure to meet the user-specified performance requirements, even when multiple user requests execute concurrently.
