I find it puzzling that aws uses rust so much yet don't have an official rust aws sdk

That metric doesn't really matter for that purpose. If AWS gets enough customer requests to warrant building a rust SDK, they'll do it. It doesn't have much to do with internal rust adoption at AWS.

I don't think any of these companies use Rust much. You may find teams here and there using it but the vast majority of the Rust type stuff is written in C++ or Java.

Firecracker is written in rust and is from Amazon.

Firecracker being a modified fork of Google’s crosvm project.

Not really. They share some dependencies, and there's quite a bit of desire to work on those dependencies together (via the rust-vmm project).

It literally forked from crosvm.

It depends on what you mean by "much." If you mean "as a volume of LOC of total software development," absolutely. But if you mean "not being used for anything big" or "not being used for anything important," that is very much wrong.

In what concerns Microsoft, I am yet to see anything besides Win32 and WinRT bindings generation.

UWP/WinUI foundations are in C++ and .NET.

Azure Sphere, despite all the security selling marketing uses C based SDK.

Windows kernel seemed to be in the right direction adopting more C++ and less C, specially with the userspace drivers COM SDK, but they just reverted to more C support on the latest versions.

So in what concerns Microsoft, I look forward to their Rust's adoption, although currently its adoption is yet to be reflected on the Windows development ecosystem.

While not official, there is at least one or two Amazonians working on https://github.com/rusoto/rusoto which is a pretty great Rust AWS SDK.

Just wanted to point out in case you didn't see it, that rusuto currently needs a fulltime maintainer! They're in maintenance mode currently, no one is spending much time on it since the primary maintainer stepped back.

An AWS tech lead mentioned that they were working on an official Rust SDK a while back
