Abstract: Methods, apparatus and articles of manufacture to provide workflow subscription management in a cloud computing environment are disclosed. Examples disclosed herein cause a graphical user interface associated with a virtual appliance to present a template to create a first workflow subscription, the template including (1) a first input element to specify a workflow to be performed, and (2) a second input element to specify an event topic that is to trigger operation of the workflow, the second input element including a field to specify at least one of (i) whether other workflow subscriptions are to be blocked from an event notification associated with the event topic until the first workflow subscription has acted upon the event notification, or (ii) whether a reply notification is to be sent to a service associated with the event notification after the workflow has completed in response to being triggered based on the event notification.

Abstract: Methods, apparatus and articles of manufacture to provide client extensibility during provisioning of a composite blueprint are disclosed.

Abstract: Methods, apparatus and articles of manufacture to provide workflow subscription management in a cloud computing environment are disclosed. Example methods disclosed herein include causing display of a template corresponding to an event topic that is 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. Disclosed example methods also include triggering the workflow in response to an event notification associated with the event topic.

Abstract: A computer system includes hosts for hosting virtual infrastructures. Compute resources provided by the hosts are allocated to user groups (e.g., departments, projects) in the form of reservations that define amounts of resources available to the user groups. Tags can be associated with both hosts and with reservations. A reservation has access to resources of a host having a host tag that matches a user tag associated with the reservation. Thus, to make a host available to a reservation, either 1) a tag can be added to the reservation to match a tag of the host, or 2) a tag can be added to the host to match a tag of a reservation. This can be more convenient than a case in which both a host and a reservation must be configured to give the reservation access to the host.
