Declarative Policy Support for Cloud Application Orchestration

Abstract

The orchestration of applications and components in the Cloud is a topic that has been receiving notable attention. As the use and number of cloud computing platforms increases, the need for a standardized means of describing, deploying and managing applications across heterogeneous providers becomes even more apparent. To meet this need we present an extended CAMP platform, capable of describing, deploying and managing applications and components across heterogeneous clouds. Our platform makes use of policies that are described in a declarative YAML format. In order to process policies defined in our extended platform we also present declarative policy directives that specify actions that may be taken in response to our policies. Our extensions to CAMP will allow CAMP compliant platforms to be capable of performing orchestration through the use of declarative policy descriptions, automatically orchestrating applications and components across heterogeneous cloud providers.
