Plans in Kilo [3] OpenStack

OpenStack

1

https://wiki.openstack.org/wiki/Heat/ConvergenceDesign

1. Persist dependency graph

2. Concurrent stack update

3. Decouple resource deletion tasks and move it to garbage collector

2 Autoscaling

https://wiki.openstack.org/wiki/Heat/AutoScaling

3 Heat Template format usability improvements

https://etherpad.openstack.org/p/heat-useablity-improvements

1. Add "parameter_defaults" to the environment

2. Support better access to nested attributes

3. Support preview the changes of stack update

4. Stack update allow without -P(parameters)

Heat Convergence - resolving any and all questions
