> all companies paying for computing resources will have to pay roughly 30% more overnight on cloud expenses Well, if I rent a VPS with x performance, I still expect x performance after this flaw is patched. The company providing the virtual machine will perhaps have to pay 30% more to provide me with the same product I've been getting. Since most VPS offerings arbitrage shared resources, this will not increase costs of providing VPSes by the full performance penalty.

Well if you use m5.xlarge instances from AWS you were getting 4 vCPUs for your money. I don't expect you'll now get 5...

  No, but the underlying hardware that perviously hosted two m5.xlarge instances may instead host one M5.xlarge and one M5.medium, so that performance is not degraded.

    Yeah but AWS doesn't guarantee that "2x m5.xlarge" will meet any kind of performance requirements, particularly your own application's, do they? So you may suddenly find that your own performance requirements, that were previously satisfied by "2x m5.xlarge" are no longer being met by that configuration, and I doubt AWS will just provide you with more resources at no additional charge.

> Well, if I rent a VPS with x performance, I still expect x performance after this flaw is patched. Are there any providers that state you will get x performance? Most that I've seen say you will m processors, n memory, and p storage but don't make any guarantees about how well those things will perform.

  Last I checked Amazon AWS has a virtual processor metric not actual hardware metric. This is most noticeable in their lowest power instances which don't get a full modern CPU core.

    If the virtual metric is tied to real performance then it could mean a drop in performance while maintaining the same power rating... It will be interesting to see if vendors directly address this.

But all you are ever getting with vps offerings is a description of the number of cpus and amount of ram and suchlike. I haven't seen vps offerings that say "x" chips yield "y" performance. Granted it is sort of implied that the hardware meets certain expectations but there isn't any guarantee. I was just now reading the TOS for AWS just to check and so far as I can tell they aren't guaranteeing any kind of specific performance.
