Is this just a gimmick run by AWS and the "honest" in the logo is just a play on the host name, or is it some third-party version that adds information that AWS isn't reporting?
It's mine. It's an old Chrome extension shoved into a Lambda@Edge function that dynamically transforms the actual status page to cut out a lot of the "sea of green bubbles." I should look into updating it; it used to automatically upgrade the severity one level as well but AWS changed something.
My default tends to be Ansible because it is really versatile and lightweight on the systems being managed. That versatility can bite you though because it's easy to use it as a good solution and miss a great one. Also, heaven help you if you need to make a change on 1000s of hosts quickly.
I also use (In order of frequency):
Terraform,
Invoke (Sometimes there is no substitute for a full programming language like python),
Saltstack (1000's of machines in a heterogenous environment)
Re: performance: That's fair. I didn't realize it scaled that badly.
Re: mitogen: Thanks! I saw that once, a long time ago, but couldn't find it again. I'll have to try it; vanilla ansible is fine for me so far, but I'm hardly going to ignore a speed boost that looks basically free to implement.
One of the things companies like SUSE and RH provide is testing across a variety of expensive storage and compute platforms. It turns out that continuous integration testing is just getting started in kernel land. Major Hayden had a cool presentation at TXLF 19 about it.
UPDATE: Status page now shows it https://status.aws.amazon.com/#
