Scenario 6: VM/Resource state change notification
Leader: Peter Solagna, EGI
The scenario enables:
- Resource providers to notify interested parties about changes in the user's VM state of a proposed state change in the VMM.
- End user to build automated VM management and reactive workflows in user space.
Such notification system must enable automatic notification consumers and so there is the need to identify the standards to be used: - Standard for the payload in the notification messages - Standard for the messages transport
If such standards are available in the federated cloud infrastructure, the users will be able to implement monitoring/management tools for their workflows.
The steps I identify to have a comprehensive description of the current situation: 1) List the notification systems adopted by the technologies currently deployed in the FedClouds testbeds. 2) List the currently available standards available, and map them - if possible - to the technologies implemented in the testbeds. 3) Assess if there are missing features in the current implementations and standards. User Communities requirements needed. 4) Identify if there are standards eligible to be suggested as common standards.
When the points above are done, I suggest the following, operative, tasks:
- Technology providers should provide the status change notifications through standard formats and transport protocols
- User communities should test these notification mechanisms in their workflows, or implementing a client prototype.
Comments to the steps list, or about any other aspect of the scenario are more than welcome
I would need also to know who is willing to collaborate directly to this scenario.
