Microsoft System Center 2012 Revealed, January 19, 2012 Microsoft's System Center 2012, which we discussed in Microsoft's System Center 2012: Building A Private Cloud, is the latest attempt by a big vendor to bring private cloud to the masses. While there are many improvements to System Center, building a private cloud using anyone's software is far from easy. At Microsoft's private cloud reviewers' workshop, we got a peek at the sausage factory. There are a lot of components to configure, but Microsoft has done a good job of streamlining many of the processes.
Using quotas, you can offer control how cloud resources are consumed. In this case, this particular role is allowed as much virtual CPU, RAM or storage as needed, but the role is limited to five VMs. That means the role can run only five VMs, regardless of how many users are in the role.
Quotas can be further restricted on a per-user basis. In our case, each member of the role can use 1,024 bytes of RAM and may use only a single VM. This leaves room for other role members to use VMs, and allows us to add additional roles that can use the same cloud service.
Quota management is very dynamic, and administrators with the right access privileges can change these quotas at any time. You will have to think about your quota strategy so that you are managing your resources effectively.
