US 2020/0089516 A1 · NETWORK-EFFICIENT ISOLATION ENVIRONMENT REDISTRIBUTION

Abstract

Network-efficient isolation environment redistribution is described. In one example, network communications are surveyed among isolation environments, such as virtual machines (VMs) and containers, hosted on a cluster. An affinity for network communications between the isolation environments can be identified based on the survey. Pairs or groups of the isolation environments can be examined to identify ones which have an affinity for network communications between them but are also hosted on different host machines in the cluster. The identification of the affinity for network communications provides network-level context for migration decisions by a distributed resource scheduler. Certain VMs and containers can then be migrated by the distributed resource scheduler to reduce the network communications in the cluster based on the network-level context information. In some cases, migration decisions can be conducted with reference to both network-level context information and other application-affinity policies.

Dependent claims

A method for isolation environment redistribution in a computing environment, comprising:

surveying inter-environment network communications among a plurality of isolation environments hosted on a distributed computing resource cluster;
identifying, among the plurality of isolation environments, an affinity for network communications between a first isolation environment and a second isolation environment based on the inter-environment network communications;
determining whether the first isolation environment and the second isolation environment are hosted for execution on a same host in the distributed computing resource cluster;
and
in an instance in which the first isolation environment and the second isolation environment are not hosted for execution on the same host, migrating at least one of the first isolation environment or the second isolation environment based on the affinity for communications to reduce the inter-environment network communications in the distributed computing resource cluster.
