摘要： A cluster comprises a plurality of computer systems, wherein each of the plurality of computer systems is configured to execute one or more virtual machines. Each of the plurality of computer systems comprises hardware and a plurality of instructions. The plurality of instructions, when executed on the hardware, migrates at least a first virtual machine executing on a first computer system of the plurality of computer systems to a second computer system of the plurality of computer systems. The plurality of instructions migrates the first virtual machine responsive to a first load of the first computer system prior to the migration exceeding a second load of the second computer system prior to the migration.

摘要： In one embodiment, a method includes detecting that an application in a first node is to failover; provisioning a second node to execute the application responsive to the detecting; and failing the application over from the first node to the second node. Additionally, embodiments comprising computer accessible media encoded with instructions which, when executed, implement the method are contemplated. In another embodiment, a system comprising a plurality of nodes. A first node of the plurality of nodes is configured to monitor performance of an application executing on a second node of the plurality of nodes during use. In response to a detection that the application is to failover from the first node, a third node is configured to be provisioned to execute the application. The application is failed over to the third node during use.

摘要： In one embodiment, a computer accessible medium comprises instructions which, when executed, check a first storage from which a computer system is configured to boot for a block identified in a read request. The block is included within an image of a set of software resources to be provisioned on the computer system. If the block is stored in the first storage, the instructions supply the block from the first storage in response to the read request. Otherwise, the instructions: fetch the block from an image repository system that stores the image; store the block in the first storage; and supply the block in response to the read request. In another embodiment, the instructions store a block identified in a write request to the first storage. The instructions record that the block is modified in the first storage with respect to the image stored in an image repository system.
