- How a single-line bug cost us $2000 in AWS spend... We recently refactored a Lambda Function. We extensively tested its functionality and released it into production. And everything still worked as expected. But then the billing alarm went off.. (repost with sanitized images)
- I recorded a free, 16-session AWS Solutions Architect Professional course in the summer of 2020. I didn't check it for months, and found out today it has over 15k views 🤯 It's available here, if you're interested: youtube.com/playlist?list=…
- OMG I did it! I got all 12 AWS certs 🤓🚀 💻 🎉 💯 To celebrate, a thread with some thoughts on each exam👇
- Replying to @donkersgoodSo what have we learned: 1. Monitor AWS spend anomalies after deployments 2. Write unit tests for Lambda cache behavior 3. Don't discard symptoms like Lambda timeouts as random behavior 4. Billing alerts work! /fin
- I’m building a tool that collects every @awscloud resource through List* and Describe* calls. This could have been easy with consistent APIs. After many hours of suffering, let me tell you a few of the many ways AWS APIs are everything but. A thread 👇
- I recently found a new enumeration vulnerability in AWS. It allows me to identify valid account IDs and any IAM principal in it. I had a call with AWS security, and they say it’s by design. Well then, let’s take a look!
- Oh. Wow. Tonight I received the annual Go Build award from @Werner. I am on cloud nine. I cannot overstate how much this means to me. Thank you all for your support and appreciation. I could not have done it without you.
- Introducing: Bite-Sized Serverless, a topic-oriented learning platform. Focused on real world AWS implementations, with a CDK project included with every article. Mostly free, with low one-off pricing on advanced articles. bitesizedserverless.com
- whoa, Whoa, WHOA, what's this? Amazon EventBridge latency suddenly dropped by 67%! SIXTY-SEVEN PERCENT! Until last night P50 latency was around 430ms. A few hours ago, this dropped to 140ms 🤯 Big shoutout to the EventBridge team - this is extremely welcome!
- AWS is already removing Terraform sessions from Re:Invent 😅
- For months I have been secretly working on a website with practical educational articles on AWS Serverless. It's nearing the point where I should take it public. I am terrified.
- Amazon just released the most Amazonian response to Vercel 😁 They built a CLI toolkit which deploys infrastructure for you. The resources (CodeBuild, Lambda, CodePipeline, ...) then listens for changes in GitHub and updates your CloudFront distribution.
- My thoughts on the GenAI hype. It’s fair to say that I am very interested in everything AWS does. But I fear AWS is no longer interested in what I do.
