Cpu provisioning algorithms for service differentiation in cloud based environments
- 1. CPU Provisioning Algorithms for Service Differentiation in Cloud-based Environments Abstract: This work focuses on the design, analysis and evaluation of Dynamic Weighted Round Robin (DWRR) algorithms that can guarantee CPU service shares in clusters of servers. Our motivation comes from the need to provision multiple server CPUs in cloud-based data center environments. Using stochastic control theory we show that a class of DWRR policies provides the service differentiation objectives, without requiring any knowledge about the arrival and the service process statistics. The member policies provide the data center administrator with trade-off options, so that the communication and computation overhead of the policy can be adjusted. We further evaluate the proposed policies via simulations, using both synthetic and real traces obtained from a medium scale mobile computing application. Existing System: We examine the CPU allocation problem of providing guaranteed service per customer class. We define a class of Dynamic Weighted Round Robin
- 2. (DWRR) scheduling algorithms that under some statistical assumptions can be used to provision not approximate but exact CPU cycle percentages between competing users in overload. Under this class of policies the SLA is achieved at all times, even when the demand exceeds the capabilities of the system, while at the same time they fulfill a number of design criteria. Proposed System: We first prove analytically that a rich class of proposed controls can achieve the desired objective of the SLA. In order to avoid mathematical technicalities in the proofs, we assume heavy traffic (e.g., overloaded situations). We then evaluate the controls under more realistic assumptions, in terms of their convergence speed, the required overhead and their insensitivity to system and statistical assumptions. The evaluation is done via simulations; we use both synthetic and real traces obtained from a medium scale mobile application.
