Cloud administrators face the challenge of speed—cloud services are turned off and on at a more rapid pace than in traditional IT. While this highly responsive architecture is great for the business user, it makes managing IT utilization very difficult because administrators cannot get a clear picture of their resource pool. It is time to change their clarity into cloud service usage, and give them a deeper view.
Let’s examine how cloud administrators are now able to view compute capacity and closely track resource capacity of components with HP Cloud Service Automation 3.2 (CSA). Cloud administrators now have the ability to assess whether they face supply constraints and can automatically provision services based on the availability of resources.
How resource pool works
Within HP CSA’s Resource Management screens, you will find information about resource providers called “resource pools” (Figure 1). Administrators can now create one or multiple resource pools consisting of specific providers, with each pool providing an accurate reading of usage. For example, your organization might have three vCenter instances—one for dev, one for testing and one for production—so you would assign three separate pools to track utilization for each pool.
Resource pools can be setup to monitor specified types of information (Figure 2). These are typically chosen based on the aspects of the resource that have the greatest restrictions of availability. The types of resource information that can be tracked include:
● IPv4 Address
● IPv6 Address
● Physical Server
● Virtual Server
The first step is for a business user to subscribe to any of the service offering in the HP CSA Consumer Subscription Portal that employs this provider in the above resource pool. The resource pool will reflect information to show, for example, how many CPUs have been allocated for consumption, and how many are still available (Figure 3).
As utilization rises to 80 or 90 percent, the resource pool will trigger an alert back to the administrator (or an escalation system, as defined by the administrator) to take action. If the resource pool becomes fully utilized, new subscriptions will fail and notifications will be sent to both the administrator and the business user.
Administrators can also configure a synchronization action in the resource pool properties. This means they can establish how HP CSA will communicate with the specified resource provider to automatically update the resources in this pool. It is important to note that in order to get the full value out of HP CSA resource pools, all provisioning of IT services should occur through HP CSA, otherwise this will result in incomplete information about resource utilization. (Information can be adjusted manually by the cloud resource management administrator if needed.)

With HP CSA intelligent resource utilization, the goal is to help administrators get better visibility into how resources are used. This is accomplished by providing IT with control over investigating and remediating any resource shortages. IT can now review new subscription requests and even divert requests to a different under-utilized resource pool. These advancements to HP CSA are focused on giving IT organizations flexibility and confidence as they evolve and adapt to the new dynamics of cloud-based IT.
