Readit NewsNot sure if this applies to all web servers, but at least Caddy and a few others support this.
You don't know, but you proved your customer's point, unwillingly.
The thing is, your logic is flawed because it's (incredibly) shortsighted.
> VMware, Xen, or Hyper-V admin
Those three things essentially do the same thing, yet they're completely different beasts. You have to look for people knowledgeable on that specific product, and you might not find them.
When dealing with AWS EC2 instances? A lot more people with standardized competencies.
For companies it's just great because they can hire from a much larger pool of candidates.
It's great for workers too, because they can pick my skills and go work at another company where I'll be immediately productive, meaning they'll have a much smoother onboarding process (learning the business domain rather than fighting the technology).
The main difference between cloud vs on-prem/colo/dedicated is that you need SRE/DevOps for the first, and sysadmins for the second.
Native Linux (and Docker) support would be something like WSL1, where Windows kernel implemented Linux syscalls.
Spawning new processes for every user is possible but would probabaly be less scalable than even thread-switching.
European speaking. For completeness:
Financial directive PSD2[1] allows to use an SMS as a 2FA only because there is an KYC already done for that number (anon SIM are no longer allowed in the EU)
Also note that the 2FA is not the OTP code you receive. This code is just a proxy for probing "something you have", with the "something" being the phone number which, again, is linked to a physical person/company.
I have commented this several times, but as of today, SMS is the only 2FA method that can be easily deployed at scale (all demographics, all locations, compatible with all mobile devices)

~~I get the impression there are several others, too, but that one is of especial interest to me~~ Wowzers, they really are much better now:
If you're saying "other services should offer VPC Endpoints," I am 100% on-board. One should never have to traverse the Internet to contact any AWS control plane
