OpenStack Orchestration (Heat)

Steve Baker 7ed7031466 Fetch all db resources in one query Instead of calling resource_get_by_name_and_stack once for every resource in the stack, db_api.resource_get_all_by_stack is called only once for all resources. This reduces the number of sql queries during a describe_stack_resource call to 3: 1. load the stack 2. load the template 3. load the resources This is a big improvement over the start of this patch series, which is 2 queries plus: * 1 per resource in the stack * 1 per access to a resource metadata attribute * 1 per access to a resource data value There is probably still potential to reduce queries from 3, but this may well be a fix for Partial-Bug: 1306743 Change-Id: I80be5d3de8744813d974f2e9860c148ad258f385		2014-05-08 11:54:55 +12:00

HEAT

Heat is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native ReST API and a CloudFormation-compatible Query API.

Why heat? It makes the clouds rise and keeps them there.
