If you've ever had to delete and recreate an entire Cognito app client just to rotate a secret, you know how overdue this was. #AWS #CloudSecurity 4/4

Why this matters: → Custom secrets = easier migration from other auth systems → On-demand rotation via AddUserPoolClientSecret API → Fits actual compliance and security requirements Not just a nice-to-have — this was a real gap. 3/4

Amazon Cognito now lets you bring your own client secrets and rotate them without downtime. Before: one secret, no rotation, delete the whole client to change it. Now: proper lifecycle management. Finally. 1/4

What it monitors: • Kernel issues & process limits • VPC CNI/network failures • Storage I/O & throughput limits • Container runtime failures • GPU/accelerator errors (NVIDIA, AWS Neuron) All open source. All transparent. #CloudEngineering #DevSecOps 5/5

Key features: 🔹 Runs as DaemonSet on every node 🔹 Monitors: Kernel, Networking, Storage, Runtime, GPU 🔹 Auto-detects 5+ issue categories 🔹 Integrates with EKS auto-repair 🔹 Open source = full transparency Check it out on GitHub! #OpenSource #Kubernetes #AWS 4/5

🚀 Big news for #Kubernetes users! Amazon EKS Node Monitoring Agent is now OPEN SOURCE! No more SSHing into nodes to debug pod failures. The EKS Node Monitoring Agent is now available on GitHub for everyone. #AWS #Kubernetes 1/5

One reframe: Stop: "how I built it" Start: "how I designed, owned, and drove impact" Been through an Amazon loop? What surprised you most? #AWS #SoftwareEngineering #TechCareers 6/6

Common mistakes: ❌ Tasks instead of ownership ❌ Vague stories, no data ❌ Dodging failure questions ❌ Wrong communication level 5/6

Amazon loop interviews ≠ "just more interviews." 3-5 hours. Back-to-back. Every round tests Leadership Principles — even technical ones. Here's what actually happens 🧵 1/6

What's the most complex scheduling problem you've solved on AWS? #AWS #Serverless #CloudComputing 8/8

More tips: → Clean up one-time schedules after execution (they count against quotas) → Batch small tasks to maximize free tier → Templated targets for Lambda/SQS/SNS, universal for everything else 7/8
