Subject: [OASIS Issue Tracker] Updated: (CAMP-11) Expression of Scaling Policy
[ http://tools.oasis-open.org/issues/browse/CAMP-11?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Martin Chapman updated CAMP-11: -------------------------------- Assignee: Alex Heneveld > Expression of Scaling Policy > ---------------------------- > > Key: CAMP-11 > URL: http://tools.oasis-open.org/issues/browse/CAMP-11 > Project: OASIS Cloud Application Management for Platforms (CAMP) TC > Issue Type: New Feature > Components: Spec > Reporter: Anish Karmarkar > Assignee: Alex Heneveld > > Annex A leaves scaling largely as a vendor specific definition. However, more detail would be useful for those interested in building a basic level of a scale-out model that will work regardless of platform vendor selection. It should be worthwhile to define how a scaling policy could be expressed in a portable format, and perhaps a basic extension mechanism to allow service providers to implement scaling models of varying sophistication. > The specification could define a way to express a scaling policy in the PDP so that an auto-scaling application can still be portable between service providers. The exact implementation of the scaling may vary considerably, but the basic concepts for a policy, a scale-up event trigger, a scale-down event trigger, and some form of a callback that relates to each of the events. > For maximum portability, some standard meanings for the contents of the policy would also be useful. > This issue is related to https://tools.oasis-open.org/issues/browse/CAMP-9 > This issue was raised by Adrian Otto and was drupal issue 1065. > ------- > When the issues was opened the following clarifications of the issues was added: > Service providers implementing a CAMP platform would like to be able to offer auto-scale as a feature. Provide some facilities that allow a policy to be expressed within the platform, perhaps when an application assembly is instantiated, that will describe which policy should be used for managing that assembly. > Furthermore, we would like to be able to allow CAMP to manage an auto-scale policy so that those service providers can offer the service in a way that allows that policy to be portable between CAMP platforms. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
