August 24 Fargate outage

As an ECS on Fargate fan, I got a lot of questions about the recent incident / outage. Let's talk about it... 🧵 1/43 TL;DR: meh. Incidents happen and this one did not teach us anything new about building on AWS. I expect more profound drama during these roaring 20s!

Disclaimer: everything fails all the time! I view incidents as "normal" and this thread reflects that. Yes, AWS had incidents. Yes, us-east-1 is HUGE so it gets interesting incidents. Yes, AWS is bad at communication. This is the default and well-known state!

Observability 101

The thoughts in the quoted thread ruffled some feathers, so let's do a quick observability 101. Alternative title: "how to not get abused by your logging/ monitoring/ o11y vendor" A 30-tweet thread cause I am trying to micro-blog 👇 https://twitter.com/iamvlaaaaaaad/status/1543892406969442304

If you speak Romanian, I already gave a talk on this topic at Bucharest's Cloud Native Meetup in September 2021! See this video, starting at 51:05: https://youtu.be/XFP1-45ZL08?t=3065 Watch that instead, as this thread is an English re-cap of that talk!

Rant: can we please stop pretending that serverless in 2022 is the same thing as serverless in 2016?

Rant: can we please stop pretending that serverless in 2022 is the same thing as serverless in 2016? We're intellectually masturbating about what "serverless" means and we're confusing people, all while we're like on serverless v3! Of course v3 products don't fit in v1 boxes!

TL;DR: Serverless v1 came in with a bang but failed to capture most of the market. Serverless v2 is an effort to apply serverless practices to things most people already know and do, but "it's nOt TruE sERvErLeSs". At the same time, Serverless v3 is exploring what's next.

Coding exercises for interviews need to not be terrible

Brave: you're hiring and your process includes a coding quiz/take-home exercise Really brave: you're doing the above and assuming everybody has a dev env with 15 specific tools and DBs already installed, configured, and working perfectly "SWE candidates are so bad these days"🙄

Scaling containers on AWS in 2022

What's the fastest way to scale containers on AWS in 2022? Is EKS faster than ECS? What's faster: serverless workers (Fargate) or to serverful workers (EC2)? What about App Runner and Lambda? Now we know: https://www.vladionescu.me/posts/scaling-containers-on-aws-in-2022

DevOps needs to calm down

Old: Ops does things by hand, takes forever, slows down companies. Idea: Ops can use code to automate things and work closer with Dev to speed things up! Dev will optimize for easier Ops too. Fked up now: DEVS MUST ALSO WRITE TERRAFORM AND LEARN EVERYTHING ABOUT KUBERNETES!

AWS Helmet

AWS: repeatedly punches you in the face. Also AWS: here’s AWS Helmet, so taking those punches is easier. Yay, we’re customer obsessed! Bias for action! Don’t get me wrong, the helmets are awesome. But they should not be needed! With scale comes responsibility, and all that.

AWS' future

💯 AWS has 2 paths into the future: 1⃣ be a utility: provide low-level building blocks, like an electricity provider or an ISP 2⃣ re:Invent: focus on DX AKA proper higher-level services I fear they'll do 1⃣ while also pretending to do 2⃣ which will confuse and hurt developers. https://twitter.com/loujaybee/status/1473946267713777668

AWS has known this since 2018, so it's about time we saw a direction forming. I am not seeing that at all! That worries me. We're still years away from this having major impact, but we're seeing the cracks appear and Lou showcases that so well in his thread!

Dependabot for 99% of my projects: ✨ 🥰 🌸 🍰 🎶 🧸 🥂 Dependabot for the 1% damn Node.js projects: 💢 🤬 💥 🔥 💀 😤 ⚰ Oh, I so wonder why folks end up hating security and automation. Of course they do when their first experience is a REPEATED PUNCH TO THE FACE!
