How Applogic performs Resource Allocation at the CPU Level?

[devma07]

I would like to understand better how Applogic perform resource allocation, mainly the CPU, customer is comparing resource allocation from Applogic with VMware.

Let me display the scenario, customer is creating VDS from the CentOS templates and configuring then to have for instance 5 CPU's, when we deploy and start the VDS, the number of cores in the Dashboard reduces in 5 CPU's, eventough there is no load at the server just booting, customer claims that, in VMware, the CPU's will be consumed as the need of processing power increases (dynamic processor allocation), guess is the VMware shared resource pool functionality.

Does Applogic allocates CPU in an EXCLUSIVE way ?

Tks in advance for your comments,

Hi Marcelo,

Yes, AppLogic allocates resources differently from virtual machine managers. AppLogic reserves the resources you assign to your applications in order to make sure they are available when needed.

This difference is due to the differing goals between virtual machine management and cloud computing. With virtual machines, you mostly want to cram as many as possible under-loaded VMs into the fewest possible number of physical servers; with cloud, and AppLogic specifically, you want to ensure that composite, multi-tier applications will have predictable and consistent performance -- that will not be affected when someone adds one more unrelated VM
