摘要： A system and method for dynamically adjusting the amount of memory allocated to a virtual machine includes generating, by a memory resizing system, a current memory usage profile for the virtual machine. The memory resizing system and the virtual machine are part of a virtual computing system and the current memory usage profile is generated by mapping, as a function of time, memory usage information from the virtual machine. The system and method also include computing an upper baseline based upon a peak memory usage in the current memory profile, updating an initial memory allocation of the virtual machine based upon the upper baseline and a predetermined threshold for obtaining an initial revised memory allocation, determining a moving average of memory usage from a historical memory usage profile, and updating the initial revised memory allocation based upon the moving average of memory usage for obtaining a final revised memory allocation.

摘要： The disclosure relates to a method of switching data sources during a rolling upgrade of a leader-based distributed service. In at least one implementation, the method includes establishing, at a computing device in a cluster of devices in a network, a watch for notification of completion of a rolling upgrade on all devices in the cluster; restarting the computing device on completion of the rolling upgrade; switching, at the computing device, from a first data source to a second data source once the rolling upgrade is complete on all devices in the cluster; if the computing device is a leader device in the cluster, migrating tasks from the first data source to the second data source after completion of the rolling upgrade; and if the computing device is a non-leader device in the cluster, determining if task migration to the second data source is done and, when done, sending a store object to the second data source.

摘要： A method of determining an optimal host machine to place a virtual machine in a virtualization environment is described. The virtualization environment includes a first rack of host machines and a second rack of host machines, where a first host machine of the first rack of host machines is designated as a leader node. The method includes receiving a request to launch a second virtual machine configured to communicate with a first virtual machine. The method includes identifying, from the first rack of host machines and the second rack of host machines, a cluster of host machines. The method includes computing, for each host machine of the cluster, an aggregate network bandwidth consumed by the host machine. The method includes selecting a host machine from the cluster based on the aggregate network bandwidth computed for the selected host machine. The method includes launching the second virtual machine on the selected host machine.
