The ability to manage, monitor and control PaaS instances from a single location. This is critical for making PaaS cost effective and maps cleanly to the notion of a centralized organization who is responsible for hosting a PaaS solution.
Centralized administration means having local data collection happening within the PaaS instances themselves. This data should reflect the operational needs of the PaaS environment, for example:
Administration activities that should be available to PaaS Administrators should include:
Starting/Stopping nodes within a PaaS instance
Ability to modify configuration (e.g. JDBC Data Sources)
Scale Up or Down facilities (e.g. adding a new node to PaaS instance)
