Stop Load Balancing VMs

Most SMBs over provision heavily anyway, at least in CPU. Memory they often do. It is disks where they always cut corners and often they cut corners because of trying to do things like load balancing.
This is a case where the attempt to leverage a performance feature, load balancing, is causing them to do exactly a set of things that hurts their performance.
I've seen some very heavily overprovisioned servers spun up by engineers...like 5GB of RAM for a Server 2008 R2 server running nothing but SW...I think it was 1 vCPU with 2 core allocated too. I argued with the engineer on that one...

That's pretty light for a SW install. Normally we say a minimum of 6GB and 2 vCPU. Unless it is doing almost nothing, SW needs a lot of power to run well.

LOL I was thinking the same.. SW needs a ton of resources to run well.

Not from what I've seen. I would have provisioned no more than 3GB. The scans are mostly CPU intensive, not so much memory.

but really...what have you seen in your illustrious career?

I've seen plenty. I don't pretend to know it all, but every SW instance I've ever seen, it's CPU intensive on the scans but not that memory intensive.

I know that live load balancing is fun when you have to implement a backup solution, too. Or, at least, it sure can be. Maybe not all of the time, but every time I have come up against it it's a real nuisance.

I don't pretend to know it all, either. Somehow, I just usually do.

If you are doing system level backups, it should work seamlessly or the load balancing is failing. But as for taking VM image backups, yeah, that's a lot more complicated for sure.

Yes, VM snapshots. Pain.
