  • Publication number: 20190220298
    Abstract: A method of determining a set of virtual machine instances in a virtualized system to be scaled in response to a variation in workload of a service or application component, the method comprising generating respective sets of aggregated metrics for respective ones of multiple virtual machines, generating a directed graph in which nodes representing a resource of one or more of the multiple virtual machines are linked using one or more edges, the weight of each of the edges representing a time-lagged partial correlation value and a time lag value representing a measure of when to scale one resource relative to another, determining the set of virtual machine instances to be scaled by removing edges of the directed graph whose weight falls below a threshold measure and removing nodes whose incident edges have been removed, and scaling the weight of remaining edges of the directed graph relative to a selected node of the graph.

  • Publication number: 20160055025
    Abstract: A method, in a virtualised system, for balancing a load across multiple virtual machines instantiated over physical hardware of the system, including vertically scaling the capacity of respective ones of the VMs up to a physical capacity limit, LPHY, from an initially allocated physical capacity, LVIRT, by providing access to additional resources of the physical hardware in response to an increased load causing the or each VM to reach or exceed a threshold capacity LT1, and horizontally scaling the capacity of the system by supplementing the multiple VMs with an additional VM instantiated using a hypervisor of the system when a predefined proportion, U1, of the VMs have a capacity LPHY.
