This might be the worst vulnerability we've seen to date...
On-Prem datacenters, this is potentially good (It's forcing people to run denser who were not coming close to the limit). people close to the limit will just have to order gear.
Uh what? Potentially good. Even of you have the extra resources, you paid for them. So how can this be potentially good to lose them?

It teaches the on-prem staff to learn how to build their systems appropriately.

That's like saying me taking 30% of your paycheck teaches you to spend your money appropriately and not be wasteful..

I might try that.... give m 30% of your paycheck!

Even before Ryzen, I have always thought AMD to be a good bang for the buck in the desktop market. Unless you had the need for the extra horsepower from the better Intel chips you could get better bang for the buck from AMD.
Desktop lacks the licensing complications of the server size. For desktops, before this AMD was still great. But this gives it a HUGE incentive on servers, too!
I realized that just pointing out the desktop part too. Honestly why go with a Microsoft server the complexity they add with their licensing is reason enough to avoid them. So many ways to offer functions you get with Microsoft servers with Linux.

That's basically the same concept as losing 30% resources

What's worse is that your power usage will go up as well (likely at least).

So for those that uses only 1 virtual processors for their VMs will be needing to use two now?

No. . . 1.3 vCPU rather than 1 vCPU

No, this affectst he amount of physical CPU you need. How vCPU is affected will be complex and not predictable in that way. That is primarily affected by threading, not per thread performance.

https://www.wired.com/story/critical-intel-flaw-breaks-basic-security-for-most-computers/From what I’ve seen, it’s just Intel making that claim. As they won’t expose what the flaw is, it’s safe to assume that they are lying.

With Intel hiding the flaw, no one knows what to patch and what not to. Intel appears to be a very bad actor here. The claims are that this is an Intel bug, which means that there is no association with other processors. Intel claimed others were affected but refused to substantiate the claims. I feel like we are being bullied as an industry by a single, overly large player.
