Provisioning of node based on downsizing or migration

A method for capacity management of nodes at point of presence (POP) systems in a cloud-based multi-tenant system, the method comprising:

• receiving a request at a cloud orchestration server for provisioning a node in a POP, wherein the cloud orchestration server receives a plurality of parameters from a plurality of hypervisors of the POP;
• determining if there is a triggering of one or more parameters from the plurality of parameters at the POP, wherein determining triggering of the one or more parameters includes determining if the one or more parameters are above respective threshold values;
• selecting downsizing or migration of one or more nodes of a plurality of nodes based on the triggering of the one or more parameters, wherein:
• the downsizing includes reduction in provisioned CPU core utilization or memory utilization that are determined to be underutilized,
• the migration includes the one or more nodes migrated from the hypervisor to another hypervisor, and
• the downsizing has higher priority of selection than the migration;
• and
• performing based on the selection of the downsizing or the migration of the one or more nodes to provision the node at the hypervisor of the POP.

A capacity resolver system for managing capacity of nodes at point of presence (POP) systems, the capacity resolver system comprising a plurality of servers, collectively having code for:

• receiving a request at a cloud orchestration server for provisioning a node in a POP, wherein:
• the cloud orchestration server receives a plurality of parameters from a plurality of hypervisors of the POP, and
• the plurality of parameters includes Central Processing Unit (CPU) Core utilization, memory utilization, disk utilization and Virtual File System (VFS) availability of a plurality of nodes of a hypervisor;
• determining if there is a triggering of one or more parameters from the plurality of parameters at the POP, wherein determining triggering of the one or more parameters includes determining if the one or more parameters are above respective threshold values;
• selecting downsizing or migration of one or more nodes of the plurality of nodes based on the triggering of the one or more parameters, wherein:
• the downsizing includes reduction in provisioned CPU core utilization and/or the memory utilization that are determined to be underutilized,
• the migration includes the one or more nodes migrated from the hypervisor to another hypervisor, and
• the downsizing has higher priority of selection than the migration;
• and
• performing based on the selection of the downsizing or the migration of the one or more nodes to provision the node at the hypervisor of the POP.
