It's been a while since I gave @awscloud a livethread exploration.

For novelty based upon today's Amazon Linux issues, let's focus on Amazon Linux 2022, in the new EC2 Launch Wizard, in the Northern California region. Like the instance name, this is a 💩📬🧵.
There is something ever-so-slightly-screwy when a search for a full AMI ID returns over 5K results.
With only a slight bit of whining about needing to manually set IOPS for a gp3 volume, we're in. Yay.
lsmod shows only a few things loaded, which is good for a minimal install. rpm -qa | wc -l shows 287 packages installed, 1.1GB taken up on disk.
The version of python that would be installed could best be described as "unsettlingly modern for an enterprise distribution."
Let's see what's going on here. 'yum provides' tells me that the tools I want live within the "pcp-system-tools" package; the "pcp" portion is because I'm about to cause incredible amounts of mayhem at this rate.
This system is, like an AWS corporate comms person without a looming crisis to worry about, bored out of its mind.
Not super thrilled that IMDSv2 isn't mandated for new instance spin-ups, (I'd love an SCP to that effect-- #awswishlist) but at least it's enabled.

Retrieving tags from IMDS needs to be explicitly enabled for the instance. Okay, fair.
AL2022 is based upon @fedora, which targets a lifecycle of roughly 13 months. Y'know, twice the lifetime of a Google consumer product.

@awscloud is committing to support each AL2022 release for five years.

*DING* goes @bitintegrity's email with a Career Opportunity.
"You were involved with the CentOS project, so you either know how to support a distro for a decade, or alternately rug-pull your customers with a year's notice, depending upon your preference and era. Wanna come be sad all the time again?"
"Can I use Extras, or EPEL, or RPMforge?"

"No," says @awscloud, "but you can create your own RPMs."

"Got it, I can use Docker and npm," responds anyone with half a lick of sense.
This screenshot will upset almost everyone, and will likely be the tweet that causes people to finally snap and come for me.
I have absolutely not forgotten that sudo's logo is a horrifying anthropomorphic sandwich, so let's fix that real quick.
And this basically kills the crab, so the experiment ends here. I'm turning it off, as a t2.micro in us-west-1 is roughly 16% more expensive because everything here in San Francisco is.

So far, so good, @awscloud Linux team.

Remember to install npm and Docker!

I'm at the AWS Summit in NYC, where I believe that nicknames are for friends--and Gennifer Artificial Intelligence is no friend of mine.

Good morning.
Thirsty much? Image
A game / challenge at the AWS Startups booth: how long can an AWS employee go without mentioning GenAI? Someone just made it all the way to one minute, ten seconds! Image

Oh god I have to take a technical cert too.

Okay. Let's do Networking Specialty. Practice question 1:

Correct answer is B. Image
"Wrong!" says the answer key, "it's B because network load balancers don't support client IP preservation." Image
Except that they do. They absolutely do. They have for the past year. I'm just a boy, standing in front of an AWS Cert team, asking them to do their damn jobs. Image

Today's cloud marketing story is called "The Tale of Hot Rebecca," and is a truthful recounting of dinner last night.

Strap in; it's a fun ride.
Back in my early 20s, I had a number of friends / acquaintances in my (primarily Jewish) social circle named "Rebecca." It was kind of a problem.

("Can't we spray for them?"
"…not since the 1940s.")
So every Rebecca got an adjective, much like the seven dwarves. One of them asked me once what her adjective was, and I responded in a fit of unadulterated honesty, "you're Hot Rebecca" because honestly? Damn.

Made it to the #GoogleCloudNext keynote seating finally. Let's see how this goes now that the world is starting to wake up to a "much of the AI hype is unwarranted" reality.
Boeing: "HOW ARE THEY DOING IT?!"
Airbus: "We bought a torque wrench?"
Boeing: "No, how are you being a featured customer testimonial at #GoogleCloudNext?"
Airbus: "Oh, that? We made a strategic decision to not be walking poster children for corporate negligence." Image
In any case, fear not. I am here for this. Image

And now, some DevOps / SRE / Sysadmin / Ops / ENOUGH already tips I learned from early in my career--brought to us by our friends at Chex™ Mix. All of these are great ideas that you should implement immediately... Image
DNS is notoriously unreliable, so use configuration management to sync all of the servers' /etc/hosts files. Boom, no more single point of failure.
Future-proofing is an early optimization, so don't do it. Every network should be a /24 because that's how developers think. I mean come on, what are the odds you'll ever have more than 253 hosts in a network?

And the Amazon earnings are out for Q4. A miss on @awscloud revenue by $20 million because analysts didn't expect one of you to turn off a single Managed NAT Gateway.

Let's explore deeper into their press release.
For 2023, AWS sold $90.8 billion of services, most of which were oversized EC2 instances because you all refuse to believe Compute Optimizer when it tells you there are savings to be had if you're just a smidgen more reasonable.
Word frequency in the earnings release:
Customer: 87
Employee: 11
Generative: 16
Cloud: 24
Serverless: 3
DynamoDB: 2
Union: 0
