摘要
Optimised placement of virtual machine (VM) images in cloud computing environments, comprising: receiving user request for deploying and indicating new VM-image; reading VM resource usage profiles (user-specific if available) comprising first consumption data over first time period 303; reading resource pool profile comprising second resource consumption data over second time period 302; for each of the resource-pool profiles, aligning the read VM and resource-pool usage profiles, calculating an aggregated resource consumption profile 301 predictive of total resource consumption; and determining resource pools having the least aggregated consumption. Pool with least resource usage can have lowest integral resource consumption value of the aggregated not exceed threshold 306. User specific profile comprises rules for guaranteeing accordance with service level agreement. Advantages comprise: instantiation of VM-instances at future times when they are needed even if they cannot be provided at current time; automatic, dynamic instantiation of VM-instances adapted to changing workloads of resource-pool.
