Processes for managing computing processes within a plurality of data centers configured to provide a cloud computing environment are described. An exemplary process includes executing a process on a first host of a plurality of hosts. When the process is executing on the first host, a first network identifier associated with the plurality of hosts is not a network identifier of a pool of network identifiers associated with the cloud computing environment and first and second route tables respectively corresponding to first and second data centers of the plurality of data centers associate the first network identifier with the first host. The exemplary process further includes detecting an event associated with the process. In response to detecting the event associated with the process, the first and second route tables are respectively updated to associate the first network identifier with a second host of the plurality of hosts.

Support for multi-AZ management appliance networking

Some embodiments of the invention provide a method for performing congestion control for a particular packet flow associated with a source first host computer operating in a network. The method is performed at the first source host computer. The method determines a bandwidth threshold specified for the particular packet flow. Based on the bandwidth threshold, the method allocates an amount of bandwidth to the particular packet flow. The method periodically receives sets of contextual data associated with the particular packet flow. For the received sets of contextual data, the method iteratively (1) computes a current bandwidth consumption by the particular packet flow and (2) based on the sets of contextual data and the current bandwidth consumption, adjusts the amount of bandwidth allocated to the particular packet flow.

Bandwidth utilization-based congestion control

A virtual machine (VM) is migrated from a source host to a destination host in a virtualized computing system, the VM having a plurality of virtual central processing units (CPUs). The method includes copying, by VM migration software executing in the source host and the destination host, memory of the VM from the source host to the destination host by installing, at the source host, write traces spanning all of the memory and then copying the memory from the source host to the destination host over a plurality of iterations; and performing switch-over, by the VM migration software, to quiesce the VM in the source host and resume the VM in the destination host. The VM migration software installs write traces using less than all of the virtual CPUs, and using trace granularity larger than a smallest page granularity.

Memory copy during virtual machine migration in a virtualized computing system

System and computer-implemented method for managing multi-availability zone (AZ) clusters of host computers in a cloud computing environment automatically detects a degraded state of a first AZ in the cloud computing environment based on host failure events for host computers in a first cluster section of a multi-AZ cluster of host computers located in the first AZ and a recovered state of the first AZ based a successful scale-in operation of another multi-AZ cluster located partially in the first AZ. In response to the detection of the degraded state of the first AZ, a second cluster section of the multi-AZ cluster of host computers located in a second AZ is scaled out. In response to the detection of the recovered state of the first AZ, the second cluster section of the multi-AZ cluster of host computers located in the second AZ is scaled in.

Degraded availability zone remediation for multi-availability zone clusters of host computers

Methods and devices for providing reserved failover capacity across a plurality of data centers are described herein. An exemplary method includes determining whether a management process is executing at a first data center corresponding to a first physical location. In accordance with a determination that the management process is not executing at the first data center corresponding to the first physical location a host is initiated at a second data center corresponding to a second physical location and the management process is executed on the initiated host at the second data center corresponding to the second physical location.

Reserving failover capacity in cloud computing

A managed object of a virtualized computing environment, which contains the runtime state of a parent virtual machine (VM) and can be placed in any host of the virtualized computing environment, is used for instantly cloning child VMs off that managed object. The managed object is not an executable object (i.e., the state of the managed object is static) and thus it does not require most of the overhead memory associated with a VM. As a result, this managed object can support instant cloning of VMs with a reduction in memory, storage, and CPU overhead relative to when a parent template VM is used.

Provisioning executable managed objects of a virtualized computing environment from non-executable managed objects

A method of migrating a network file copy (NFC) operation from a first host computing device to a second host computing device includes the steps of: transmitting a first request to the first host computing device to execute the NFC operation, wherein the NFC operation comprises transferring data from a shared datastore to another datastore; after transmitting the first request, selecting the second host computing device to complete the NFC operation in place of the first host computing device, and transmitting a second request to the first host computing device to stop executing the NFC operation; after transmitting the second request, detecting a message indicating that the first host computing device completed the copying of a first portion of the data; and in response to the detection of the message, transmitting a third request to the second host computing device to perform the remainder of the NFC operation.

Migration of network file copy operations between host computing devices

The present disclosure describes a technique for honoring virtual machine placement constraints established on a first host implemented on a virtualized computing environment by receiving a request to migrate one or more virtual machines from the first host to a second host and without violating the virtual machine placement constraints, identifying an architecture of the first host, provisioning a second host with an architecture compatible with that of the first host, adding the second host to the cluster of hosts, and migrating the one or more virtual machines from the first host to the second host.

Honoring resource scheduler constraints during maintenances

The disclosure provides an approach for eliminating issues associated with the use of an L2 extension and ARP calls after migrating a virtual machine from one host to another host. The approach involves placing nodes within a network within their own subnetworks, each subnetwork having an IP address range of one address. Placing nodes into subnets of one avoids intra-subnet forwarding, eliminating the need for ARP calls and for L2 extensions.

Migration of virtual machine located on its own network

A method for migrating a virtual machine (VM) includes establishing a first connection to a first cloud computing system executing a first VM, and establishing a second connection to a second cloud computing system managed by a second cloud provider, which is different form the first cloud provider. The method further includes instantiating a second VM designated as a destination VM in the second cloud computing system, and installing a migration agent on each of the first VM and the second VM. The migration agents execute a migration process of the first VM to the second VM by (1) iteratively copying guest data from the first VM to the second VM until a switchover criteria of the migration operation is met, and (2) copying a remainder of guest data from the first VM to the second VM when the switchover criteria is met.

Cross-cloud provider virtual machine migration

Systems and techniques are described for using virtual machines to write parallel and distributed applications. One of the techniques includes receiving a job request, wherein the job request specifies a first job to be performed by a plurality of a special purpose virtual machines, wherein the first job includes a plurality of tasks; selecting a parent special purpose virtual machine from a plurality of parent special purpose virtual machines to perform the first job; instantiating a plurality of child special purpose virtual machines from the selected parent special purpose virtual machine; partitioning the plurality of tasks among the plurality of child special purpose virtual machines by assigning one or more of the plurality of tasks to each of the child special purpose virtual machines; and performing the first job by causing each of the child special purpose virtual machines to execute the tasks assigned to the child special purpose virtual machine.

Parallel and distributed computing using multiple virtual machines

In a computer-implemented method for augmenting at least one physical device with virtual information indicia corresponding to the at least on physical device supporting a virtualization infrastructure is observed. Based on the observed indicia, virtual information of said virtualization infrastructure correlating to the at least one physical device is displayed.
