Abstract: Methods, apparatus and articles of manufacture to provide client extensibility during provisioning of virtual computing resources are disclosed. An example event broker apparatus includes a subscription manager to manage subscriptions to event topics associated with provisioning of a virtual computing resource. The example apparatus includes a meta-topic subscriber to identify a subscription request by a service for an event topic and to trigger, in response to the subscription request, a meta-topic subscription to indicate a) a subscriber to the event topic and b) a type of the subscriber, the type to include at least a blocking subscriber. The example apparatus includes a topic monitor to monitor for an event corresponding to the event topic to determine whether to trigger a blocking subscriber workflow when the meta-topic subscription indicates that the type of the subscriber is a blocking subscriber or bypass the blocking subscriber workflow when the type of the subscriber is not a blocking subscriber.

Abstract: Methods, apparatus and articles of manufacture to provide client extensibility during provisioning of a composite blueprint are disclosed. An example virtual appliance in a cloud computing environment includes an orchestrator to facilitate provisioning of a virtual computing resource based on a blueprint, the provisioning associated with an event defined by the blueprint. The example virtual appliance also includes an event broker to maintain a set of subscribers to the event broker, each of the set of subscribers further subscribing to at least one event topic through the event broker, the event broker to trigger a notification of a first subscriber to a first event topic associated with the event when the event broker determines that the first subscriber is a blocking subscriber for the first event topic, the event broker to facilitate modification of the event by a blocking subscriber but not by a non-blocking subscriber.

Abstract: Methods, apparatus and articles of manufacture for governance of virtual computing infrastructure resources are disclosed. An example cloud management system includes a plurality of hosts. The hosts are to manage requests and allocate resources through one or more virtual machines. The example system also includes an administrator to configure the plurality of hosts to accommodate resource provisioning requests by assigning a constraint and a skill to the hosts to define a placement of the hosts. The placement of a respective host is to dictate an availability of the host for provisioning.

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: Methods and apparatus to scale in and/or scale out arbitrary resources managed by a cloud automation system are disclosed. An example apparatus includes an execution plan determiner to determine an execution plan for a scaling operation of an application in a platform environment based on a dependency graph; a component scaler to scale a scalable component in the platform environment corresponding to the application based on the execution plan by executing custom logic associated with the scalable component specified in the execution plan; and a dependent updater to update operation of a dependent component based on the scaling of the scalable component, the dependent component operating in conjunction with the scalable component.

Abstract: Methods, apparatus and articles of manufacture for dynamically extending a cloud management system by adding endpoint adapter types are disclosed. An example cloud management system includes: an interface to communicate with an external device; a host to manage requests and allocate resources through one or more virtual machines; and an endpoint registry to include an endpoint adapter and metadata defining the endpoint adapter, the endpoint adapter to specify communication between at least one of the host or the external device and an endpoint. In the example cloud management system, the host is to at least enable, via the interface, the external device to access the endpoint registry a) to register an endpoint adapter configuration with the endpoint registry and b) to retrieve the endpoint adapter configuration from the endpoint registry.

Abstract: Herein, rule-based handling of request for resource re-allocations provides for automated re-allocations, reducing the need for administrator intervention. The resources available to a reservation can be increased, decreased, or otherwise modified by forming and breaking selected connections between reservations and hosts. The rules herein determine which connections are to be formed or broken. Each rule associates a connection-modification criterion with a condition. In the event, the condition for a rule is satisfied by a reallocation request (and its context), the criterion is applied to the request plus its context to generate a list of connection modification plans. Each connection-modification plan identifies one or more connections between hosts and reservations to be formed or broken. Implementing the plan yields the desired re-allocation.

Abstract: Methods, apparatus and articles of manufacture for custom interface specification in a cloud management system are disclosed. An example cloud management system includes: a first interface to communicate with a second interface external to the cloud management system; and a host to manage requests from the second interface and allocate resources to the second interface as a reverse proxy for the second interface with respect to a backend. The example host is to at least: add, at the request of the second interface, an endpoint with respect to the second interface; fetch, at the request of the second interface, data for the endpoint from the backend, the backend identified for the endpoint based on metadata in a component registry; and provide the data from the backend to the second interface.

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.
