Controlling utilization in a multi-tenant platform-as-a-service (PaaS) environment in a cloud computing system

摘要

A mechanism for controlling utilization in a multi-tenant Platform-as-a-Service (PaaS) environment in a cloud computing system is disclosed. A method includes obtaining, by a resource control module executing on a computing device, an active capacity metric of each virtual machine (VM) of a plurality of VMs in a district of a multi-tenant PaaS system, the active capacity metric comprising a result of dividing a number of containers that are currently executing in the VM by a maximum number of active containers allowed to execute in the VM, determining that the active capacity metric of a source VM in the district exceeds an active capacity threshold associated with the source VM, and migrating at least one of the containers of the source VM to a target VM in the district, wherein the target VM is operating with an active capacity metric below the active capacity threshold associated with the target VM.
