Using the P-TOSCA model for energy efficient cloud

The Topology and Orchestration Specification for Cloud Applications (TOSCA) standard is used to describe a cloud application and cloud architecture in order to allow a portable deployment to other compatible cloud and multi-cloud applications. P-TOSCA is recently proposed model and proved concept, which is an extension of the TOSCA standard to improve the TOSCAs ambiguities and weaknesses. In this paper we use the P-TOSCA model for other issues that are also very important in virtualized datacenters and cloud computing, that is, to enlarge/extend the energy efficient management system. A prototype application that dynamically creates a target virtual machine on utilized physical compute node, ports the application(s) from a virtual machine hosted on an underutilized physical server to the target virtual machine in Eucalyptus cloud is presented, which is specified with P-TOSCA. After migration, the prototype application will shut down the underutilized empty physical node.
