  • Patent number: 10127081
    Abstract: Systems and methods for allocating resources to service one or more requests, the method comprising: associating with at least one host from among N hosts, in a computing environment, a first value that reflects a probability that servicing a first request will interfere with operations on the host; selecting M hosts out of the N hosts, wherein the N hosts comprise one or more resources for servicing a first request and wherein at least one of the selected M hosts is determined to be at least as suitable as N?M unselected hosts, for the purpose of servicing the first request; and prior to allocation of resources, updating for at least a first host from among the M hosts the corresponding first value to reflect that servicing the first request may interfere with operations pertaining to other previously received requests that are scheduled to be serviced by the first host.

  • Publication number: 20180173524
    Abstract: A software container image that includes components dependent on a first computer instruction set architecture (ISA) is ported to enable a container to execute using the container image on a computer having a second ISA different from the first. Porting the container image entails replacing components of the container image not compatible with the second ISA with equivalent components compatible with the second ISA. The porting is performed, in some instances, dynamically as part of running a container with the container image on a computer implementing the second ISA.

  • Patent number: 9396009
    Abstract: Machines, systems and methods for managing resources allocated in a virtualized computing network are provided. The method comprises monitoring resource usage by a first host, wherein the first host, in addition to the first host's dedicated resources, has access to a first set of sharable resources, and wherein the second host, in addition to the second host's dedicated resources, has access to a second set of sharable resources; determining whether the second host has excess resource capacity in the second host's dedicated and sharable resources, in response to determining that resource usage of the first host in the first host's dedicated and sharable resources has exceeded a resource usage threshold; and reallocating one or more resources in the second set of sharable resources from the second host to the first host, in response to determining that the second host has excess resource capacity.

  • Patent number: 7904540
    Abstract: A system and method for planning placement of virtual machines VMs in a computing environment comprising a set of hosting machines HM. The method includes constructing a bipartite directed graph-based model that represents both a current and a target placement states, both including virtual machine nodes v in VM and nodes h in HM. Using a technique of graph pruning, the method iteratively generates a plan for achieving a desired target placement starting from the current placement without temporarily violating any policy or resource constraint. The application of the pruning algorithm to VM deployment automation necessarily defines a new model. The methodology employed safely manages concurrent changes in a datacenter, so that the environment can adjust faster to changing constraints. Furthermore, the present invention allows detection of migration cycles, caused by deadlocked combinations of capacity and policy constraints, and resolving them.
