Deploying virtual machine instances of a pattern to regions of a hierarchical tier using placement policies and constraints

Abstract

A method, system and computer program product for deploying a pattern. A placement engine of a hierarchical tier selects the region(s) of a next lower tier based on placement policies and constraints at the next lower tier and availability of the artifacts required by the virtual machine instance(s) in the next lower tier utilizing the summarization of resource usage and availability at the next lower tier. The placement engine at the lowest tier selects the compute node(s) in the selected region(s) of the lowest tier to place the virtual machine instances of the pattern based on placement policies and constraints at the compute node level and availability of the artifacts required by the virtual machine instance(s) of the pattern in the compute node level. In this manner, the virtual machine instances of the pattern can be effectively deployed when the resources of the cloud environment are large and geographically dispersed.

Description

TECHNICAL FIELD[0001]The present invention relates generally to cloud computing, and more particularly to deploying virtual machine instances of a pattern to regions of a hierarchical tier using placement policies and constraints.BACKGROUND[0002]In a cloud computing environment, computing is delivered as a service rather than a product, whereby shared resources, software and information are provided to computers and other devices as a metered service over a network, such as the Internet. In such an environment, computation, software, data access and storage services are provided to users that do not require knowledge of the physical location and configuration of the system that delivers the services.[0003]In a virtualized computer environment, such as may be implemented in a physical cloud computing node of the cloud computing environment, the virtualized computer environment includes a virtual operating system. The virtual operating system includes a common base portion and separat...

AI Technical Summary

Benefits of technology

The present invention provides a method for placing virtual machine instances in a multi-tiered cloud computing environment. The method takes into account placement policies and constraints at different tiers and the availability of required artifacts to select the most suitable region and compute node for each virtual machine instance. This allows for efficient use of computing resources and improved performance of the virtual machines. The technical effects of the invention include improved placement policies for virtual machines in a multi-tiered cloud computing environment and optimized use of computing resources.

Problems solved by technology

However, such an approach is not effective when the physical and virtual resources of the cloud computing environment are extremely large and geographically dispersed since it will become impossible for the placement engine to know the state of the physical and virtual resources in such a cloud computing environment.
