    About this task

    The Cloud Provisioning and Governance application is bundled with several useful resource blocks. Create extensions to the existing resource block interfaces to add more functionality to these resource blocks. After creating an interface extension, use it in a blueprint to execute a customized operation. For example, if you do not like the way a virtual server is provisioned, extend the virtual server resource block interface by adding operations or overriding existing operations.

    Note:
    Operations in resource blocks are also called operation signatures.

    1. Open a resource block.
    2. Change the status of the resource block from Published to Draft.
    3. Click the Operations tab.
    4. Click the Override Operation icon.
