Resource planning in a private cloud?

Question

VMware

Interested in a calendar / calculator in which you can cut the pool of resources into time periods (hours or days) and distribute them between the virtual machines. That is, you need to reserve resources on an advance payment, and not issue an invoice upon consumption.

For example, let's take a resource pool of 8 GHz and 16 GB, as well as 4 machines: VM1 (1 GHz, 1 GB, 1 day), VM2 (4 GHz, 4 GB, 3 days), VM3 (8 GHz, 16 GB, 2 days) and VM4 (2 GHz, 2 GB, 2 days). It is required to distribute the work of the VM during the week.

For starters, just a calendar is enough, but ideally I would like to get a ready-made solution (compatible with vSphere) that will turn machines on / off according to a schedule.

Perhaps someone has come across similar products and can advise something?

Answer 1

Just turn on and turn off your VMs one time at a certain time or according to a schedule, vCenter Server itself is perfectly able. I did this in one project. Not to mention the external scheduler, pulling the system with scripts. For example, on PowerCli.
Another question is what kind of logic for distributing the work of virtual machines do you want to achieve: no higher than a certain level of resource utilization, as dense as possible with a certain level of responsiveness, distributed as evenly as possible over the entire time period?

Answer 2

I would either turn to the hoster, or write a clear TOR and see how it can be implemented, what to take into account and what to control.
The sphere, for example, is perfectly twitched from Windows PowerShell by a cmdlet.
Again, as far as I remember, CPU / memory quotas for a virtual machine pool can also be organized using the sphere / center tools.
