Methods, systems and apparatus to trigger a workflow in a cloud computing environment

A non-transitory computer readable storage medium comprising computer readable instructions that, when executed, cause at least one processor to at least:

• initiate display of a template corresponding to an event topic, the event topic to trigger a workflow associated with a first workflow subscription, the first workflow subscription included in a plurality of workflow subscriptions having a hierarchy, the template to include a first field to specify whether at least one other workflow subscription associated with the event topic is to be blocked until a hierarchically dominant workflow subscription has at least one of been notified of the event topic or taken action based on the event topic;
• and
• trigger the workflow in response to an event notification associated with the event topic.

A method for a virtual appliance in a cloud computing environment, the method comprising:

• causing, by executing an instruction with at least one processor, display of a template corresponding to an event topic, the event topic to trigger a workflow associated with a first workflow subscription, the first workflow subscription included in a plurality of workflow subscriptions having a hierarchy, the template to include a first field to specify whether at least one other workflow subscription associated with the event topic is to be blocked until a hierarchically dominant workflow subscription has at least one of been notified of the event topic or taken action based on the event topic;
