Machines, systems and methods for deploying virtual machines (VMs), the method comprises maintaining N message queues corresponding to N VM flavors, wherein the N VM flavors are associated with N distinguishable configuration requirements for supporting placement of at least a first VM on at least a first host with limited resources; wherein a first host from among a plurality of hosts subscribes to a first message queue from among the N message queues, in response to determining that the first host has the resources that match the respective configuration requirements for supporting the first VM placed on the first message queue; receiving a VM placement request for the first VM, wherein the VM placement request comprises information indicating a first VM flavor associated with a first message queue; communicating arrival of the VM request to one or more hosts subscribing to the first message queue.

Resources provisioning based on a set of discrete configurations

This invention relates to generating benchmarks without the need for executing the application on a specific benchmarking platform or by testing the application against known inputs and outputs. Instead, the system, in an embodiment, allows for source code comparisons to known systems to predict performance. The benchmarking can be done for varying deployment platforms and various usage patterns. The source code comparison process allows for fast performance prediction by using a distance vector.

System and method for predictive performance analysis via dynamic benchmark generation

A method for accessing data stored in a distributed storage system is provided. The method comprises determining whether a copy of first data is stored in a distributed cache system, where data in the distributed cache system is stored in free storage space of the distributed storage system; accessing the copy of the first data from the distributed cache system if the copy of the first data is stored in a first data storage medium at a first computing system in a network; and requesting a second computing system in the network to access the copy of the first data from the distributed cache system if the copy of the first data is stored in a second data storage medium at the second computing system. If the copy of the first data is not stored in the distributed cache system, the first data is accessed from the distributed storage system.

Data storage management using a distributed cache scheme

Systems and methods for remotely installing software on a computing system while the computing system is running on a first bootable image, so that the computing system is not removed from operation during the installation of a second bootable image. The method comprises constructing the second bootable image on a storage medium accessible to the computing system while the computing system is operating in a first operating environment in association with the first bootable image, customizing the second bootable image so that the computing system can operate in a second operating environment in association with the second bootable image, disassociating the computing system from the first bootable image, and associating the computing system with the second bootable image.
