Managing Service Levels in the Cloud
Cloud Manager Takes Control of Virtual Workloads
Written by Michael Astle
Under the Disks tab, you now have the option to include the system and data disks in the cost of the service.
Click Import to import the workload and attach the cost and other settings.
All that’s left is to click OK after each configuration and Import when you’re finished configuring virtual machines. Cloud Manager then shows you the monthly costs of business services to the business units. (See Figure 4.)
Changing a Configuration
If you are familiar with the previous version of Novell Cloud Manager, you know that you can add services, but you haven’t been able to change the configuration of existing services—say, add more RAM. With the latest version of Novell Cloud Manager you can now change the service level and reassign resources, including the number of virtual CPUs, RAM, storage and the networks to which the service is associated.
In the Cloud Manager console, this is easy enough to do. The IT administrator assigned to the service logs into Novell Cloud Manager and selects the service that needs to be changed. (See Figure 5.)
The administrator selects the service from the menu and can then change the expiration date and business purpose description. The service level can be changed, as well as any of the resources. The administrator can also add new workloads from the Change screen.
Novell Cloud Manager can also assign up to 10 disks to a single service, including one system disk and nine data disks.
Cloud Manager is part of the Novell WorkloadIQ strategy that helps enterprises rapidly deploy and manage private clouds using existing virtual machines or from scratch.
Making Configuration Easier with Workload Templates
Novell Cloud Manager creates a workload zone and associated host group, which are managed by a Novell PlateSpin Orchestrate server. Although these functions are outside the scope of this article, it is important to know that with the zone and host group created, Cloud Manager then discovers appropriate templates from the Novell PlateSpin Orchestrate server. These templates, which you can edit, populate the configurations for future workloads to make your job easier.
Also simplifying your job, you can copy workload configurations. Let’s say you have to create five similar workloads. When you create the first workload you can specify to copy that workload five times. Then you can use the Change screen to make any necessary tweaks to each of those workloads.
Novell Cloud Manager also generates numerous usage, cost and other reports that enable the IT organization to plan the purchase of resources based on usage trends, and they help the business to determine the cost of the services it uses and invest its limited money on services that make the most business sense.
Novell Cloud Manager is a powerful tool that enables organizations to deploy business services faster and with greater automation and consistency. At the same time, and equally important, it gives the IT organization the ability to attach costs to the business services it delivers, giving the organization the ability to control server sprawl and stop the proliferation of workload over-provisioning.
