I ran 10+ AWS accounts for years before I realized Named Profiles were the piece that makes the whole setup click! Most of us still handle AWS credentials like it's 2018 via aws configure - at least that's what I see on a regular basis!

AWS still has no hard spending cap, and I think that costs them more new users than any missing feature in their service catalog 🤷‍♂️ Last week people opened their console and saw a bill of 75 billion dollars, you know the story... One person reported 245 billion - on hobby accounts.

AWS Network Load Balancer just got listener rules! The first real routing logic on an NLB, and it starts with source IP address type 🎉 The concrete use: a single dual-stack NLB can send IPv6 client traffic to IPv6 targets and IPv4 client traffic to IPv4 targets. No translation!!

Bild

Does anyone run GitHub Actions self-hosted runners on AWS Spot capacity? We're currently wondering whether that's a realistic setup. The price difference to on-demand makes it very tempting.

You can cut your CloudWatch ingestion price in half: $0.25 instead of $0.50 per GB. The numbers are pretty clear: ingestion starts at $0.50 per GB. Storage is $0.03 per GB per month. The expensive part is the moment a byte arrives, not the months it sits there.

A budget alert can't stop a runaway AWS bill. But it can trigger something that does. A Reddit thread nailed a frustration this week: you set a budget alert at $100, and the bill is at $1,000 before you even open the email. So what's the point?

Bild

AWS Lambda just dropped its 75GB code storage limit. Functions can now run straight from your own S3 bucket. Until now, every deployment package got copied into Lambda-managed storage, capped at 75GB per region. Hit the cap? Support ticket.

Free AWS accounts for 8 hours with zero risk of a surprise bill!! Builder Center sandboxes are live 🙌 You get a pre-provisioned AWS account for eligible workshops No credit card or account setup! Ready in about 15 minutes. The limits • 8 hours per sandbox

Bild

Lambda just got a sibling that lives for 8 hours, keeps state, and answers WebSockets. AWS calls them MicroVMs! Regular Lambda is ephemeral and event-driven. MicroVMs are persistent little machines you talk to directly. • Configurable lifetime, minutes up to 8 hours

Bild

AWS is killing services faster than most of us can learn them. This round takes out Q Business and Kendra, and I think that's a good thing. What's moving to maintenance mode on July 30 • Amazon Q Business • Amazon Kendra • Amazon Cognito Sync • Bedrock Agents Classic • Simple AD

TIL you no longer need a snapshot or AMI to replace the root volume of a running EC2 instance. A plain EBS volume works now. Replace Root Volume is one of the most underrated EC2 features. It swaps the root disk in place while the instance keeps its IP, its instance store data, and its placement.

Someone's AWS bill went from $0.19 to $2,4B overnight. Yes, 2.4 billion dollars 📈 💸 For an account with a single S3 bucket that hasn't been touched since 2023 and isn't even public.

AWS just shipped a control plane for running Claude Code across your whole engineering org! 🤩 It's called the Claude apps gateway A self-hosted container on ECS, EKS, or EC2, with PostgreSQL behind it. What it fixes

Bild

Another "my AI agent blew up my AWS bill" story has landed! $6,531 in 24 hours for an 8 GB job 😅 Someone gave their agent full AWS access plus a deadline to port-scan DN42, a hobbyist BGP network with maybe 2,000 live hosts. The agent decided it needed (be prepared!!):

Bild

ECS just got a live deployment timeline in the console! 🙌 I've always liked ECS, but following a deployment was genuinely hard. Service events in one tab, task list in another, CloudWatch alarms in a third, and you still couldn't tell why a rollout was hanging.

Bild

Static IAM access keys should have died years ago. Yet every week someone posts the same horror story 🙄 Here: Admin user compromised, attacker launches EC2 instances, victim has no clue how the key leaked. That's the core problem with long lived keys: They leak silently

Bild

One company manages 6,000 AWS accounts with three people 😅 Not 60. Not 600. Six thousand! 🔥 Each customer gets their own isolated account with the full microservice stack → 40 services, ~120,000 deployed instances, roughly 1 million Lambda functions across the fleet.

Bild

Did somebody take the AWS Serverless plugin for Claude Code for a longer ride? It knows serverless patterns! 👀 𝗪𝗵𝗮𝘁 𝗶𝘁 𝗰𝗼𝘃𝗲𝗿𝘀 • Lambda, API Gateway, EventBridge, Step Functions • Scaffolds with SAM or CDK (defaults to TypeScript + CDK 💪)

Bild

I honestly don't know why more engineers don't use workshops.aws 🛠️ It's a collection of free, hands-on guides that work! The ECS Immersion Day is one that I will keep recommending! It covers Fargate from the ground up: no server management, just containers running on demand.

Bild

810 upvotes on Hacker News for a post about leaving AWS. I read the whole thing twice. Most of the complaints are skill issues imho. Going point by point from my point of view. Disclaimer: maybe opinionated, but I tried not to be. 1. Account suspension

Bild

AWS Blocks looks like SST and Local/Ministack got fused into one framework! Open source, all TypeScript 🔥 You get the abstracted "build a backend fast" part (Postgres, auth, real-time messaging, file uploads, background jobs, AI agents) plus the run-it-all-locally part with zero AWS account

Bild

Someone spent ~15M Claude tokens to build a proper skill for Bedrock AgentCore! Didn't try it yet but looks promising! Included: • SKILL .md routing file mapping use case → stack → files to open • 20 reference files covering common scenarios (Strands, Bedrock, AgentCore)

Bild

We run all of AWS Fundamentals on AWS for less than the price of lunch! The whole June bill is forecasted at $22.74. That covers a 6-account AWS Organization. Multiple serverless frontends and backends, our course platform, and everything we build. Several million requests a month.

Bild

AWS just shipped a FinOps Agent that spots a cost anomaly, investigates the root cause on its own, and drops the findings in your Slack channel! 👀 I just worked with the new DevOps agent and that's what sold me on this one. Setup was easy and it ran really nice!
