In this paper presents the Cloud providers to provide cloud consumers for two provisioning plans are On-Demand plan and Reservation plans. Because it provides users an efficient way to allocate computing resources are dynamically to meet demands. Normally, cost of utilizing computing resources provisioned by on demand plan is higher than reservation plan. Because reservation plan can provide offer of consumer can reduce the total resource provisioning cost. It can be achieved in Uncertainty of consumer's future demand and provider's resource prices. To control the cloud resources adaptively based on the Reservation Technique for Under Over Provisioning (RTUOP) algorithm.
