Hey Reader 👋

Every re:Invent recap, every AWS blog, every newsletter from the past year has been dominated by one topic. You know which one.

But while everyone was writing about agents and foundation models, the core infrastructure layer kept moving. Quiet releases. No keynote fanfare. Things that actually affect your architecture, your bills, and your day-to-day work.

In this issue, we went through the past 12 months and picked the releases that matter most to developers; no AI announcements included!

  • 11 releases
  • All production-relevant
  • Ordered by impact
  • Bonus: a quick hits section with small wins.

Beyond the pager: what to do when OpsGenie sunsets

incident.io webinar — Beyond the pager: what to do when OpsGenie sunsets. Tue, March 17, 12 PM ET.

With Opsgenie sunsetting in 2027, many teams face a forced migration. Join this technical deep dive on March 17 to learn how to build scalable, end-to-end incident workflows that move beyond simple paging. Engineering-led insights on navigating the transition, hosted by incident.io.

This issue is sponsored by incident.io. We only work with tools we'd recommend to a colleague.

📚 This Week's Deep Dive

While everyone was covering AI, AWS quietly shipped 11 infrastructure releases worth knowing about. Here are the highlights — the full breakdown with details, gotchas, and cost numbers is in the article.

  • Lambda Durable Functions — multi-step workflows with checkpointing, directly in Lambda. No Step Functions needed.
  • ECS Express Mode — container image in, HTTPS endpoint out. Canary deploys included. Built on plain ECS so you're never locked in.
  • Database Savings Plans — one commitment across RDS, Aurora, DynamoDB, ElastiCache, and more. Up to 35% off.
  • CloudFront Flat-Rate Plans — fixed monthly price, no overages, even during DDoS. Plans from $0 to $1,000/month.
  • CloudWatch Log Centralization — aggregate logs across all accounts and regions natively. First copy is free.
  • CloudFormation Stack Refactoring — finally move resources between stacks without deleting them.
  • EventBridge Cross-Account Delivery — send events directly to another account's SQS, Lambda, or SNS. One hop instead of two.
  • S3 Vectors — native vector storage at up to 90% less than dedicated vector databases.
  • Free Tier Overhaul — $200 in credits, 6-month free plan. There's a gotcha if you're using AWS Organizations.
  • SQS Fair Queues — one noisy tenant can no longer starve the rest of the queue.
  • Lambda SnapStart for Python & .NET — cold start elimination, no longer Java-only.

Plus six quick hits: Lambda streaming at 200MB, SQS messages up to 1MB, ALB JWT verification, API Gateway Developer Portal, S3 ABAC, and the NAT Gateway killer hiding in Lambda's networking settings.

That's it for this issue.

Eleven releases, most of them from 2025, all of them production-ready and available right now.
The AI wave isn't going anywhere, but neither is the infra underneath it 👀

See you soon!

AWS FOR THE REAL WORLD ⏱️ Reading time: 10 minutes 🎯 Main Learning: Every convenience layer AWS built on ECS is dead or dying, while ECS itself has not changed since 2014. Build on the primitive, and make the layer above it prove itself first. 📝 Blog Post Hey Reader 👋🏽 Getting started with an AWS service often feels more complicated than it should. Four concepts must be understood before a single container runs. A VPC is required before a single request. So, the fancy CLI that promises to do...

⏱️ Reading time: 21 minutes 🎯 Main Learning: Same CloudFront logs: 12.5s through Kinesis, S3, Glue and Athena, about 1s through Tinybird's managed ClickHouse. 📝 Blog Post Hey Reader 👋🏽 We've been running Plausible for the analytics on awsfundamentals.com. Good software, no complaints. We still wanted the data to be ours: our retention, our schema, nobody's script in the visitor's browser. So we built the dashboard ourselves. Twice, on two different backends, fed by the same CloudFront logs....

AWS FOR THE REAL WORLD ⏱️ Reading time: 11 minutes 🎯 Main Learning: A Karpenter NodePool is a placement policy, not an instance preference. Pin one instance family, and a Spot shortage moves your fleet across availability zones, where every internal call starts costing $0.01 per GB. 📝 Blog Post Hey Reader 👋🏽 Important off topic things first: Sandro got married! 🎉We were in Munich for it and it was a fantastic day! ☀️Highly recommend a wedding over sprint planning or fighting with AWS...
