AWS S3 New Feature: Re-encryption without Movement
The recent release of the UpdateObjectEncryption API marks a significant shift in how we manage data security at scale. Historically, changing the encryption of an S3 object was a “physical” operation; you had to move the bits. Now, it’s a “logical” metadata operation. Technical Deep Dive: Re-encryption without Movement The “magic” behind this update lies…
AWS Monthly (Dec ’25): The Kiro Era Begins
We ended the year with the General Availability of Kiro (Frontier Agents). Kiro is not just a chatbot; it’s a Virtual Software Development Team. Technically, Kiro is an Autonomous Coding Agent. You can assign it a ticket from Jira, and it will: It understands the context of your entire codebase, not just a single file.…
AWS re:Invent 2025: The “Agentic” Era
If 2024 was about talking to LLMs, re:Invent 2025 was about letting them actually do the work. Here is the comprehensive breakdown of the most significant announcements. 1. The Amazon Nova 2 Model Family AWS didn’t just update their models; they built a specialized fleet for different agentic roles: 2. Custom Silicon: Graviton5 & Trainium3…
AWS Monthly (Nov ’25) The Stateful Serverless Revolution
November and re:Invent 2025 brought us the “holy grail” of serverless: AWS Lambda Durable Functions. This feature introduces “Stateful Serverless” directly into the Lambda runtime. By using the new withDurableExecution wrapper, you can now write long-running workflows that persist for up to one year. When your function hits a context.wait() call, the compute is suspended…
AWS Monthly (Oct ’25): Industrializing AI Training
October was the “Quiet before the re:Invent storm,” but it brought the unveiling of Project Rainier. Project Rainier is a massive AI compute cluster featuring over 500,000 Trainium2 chips. Technically, this is one of the largest dedicated AI training environments on the planet. For us, it means the “Industrialization of AI.” The price-to-performance ratio of…
When the Cloud Sneezes, the World Catches a Cold – Lessons from the us-east-1 Meltdown
Today, once again, half the internet went dark not because of a global power failure or a cyber-attack, but because a single AWS region, us-east-1 (N. Virginia), had a bad day. Perplexity went down. Amazon itself stumbled. Substack, Signal, Fortnite, and countless others vanished into the ether. Even services like Statuspage.io, used by companies to…
AWS Monthly (Sep ’25): Vega OS & eBPF Observability
In a surprise move, AWS released Vega OS in September. Vega is a specialized, Linux-based OS optimized for the edge and high-performance UI rendering (with a React Native core). It’s ultra-lightweight and designed to boot in milliseconds, perfect for the next generation of smart devices. On the observability side, we got CloudWatch Application Map 2.0,…
AWS Monthly (Aug ’25): Big Data, Zero Effort
August was all about “Data Gravity.” Amazon Aurora storage limits jumped to 256 TiB, which effectively ends the “sharding” conversation for 99.9% of companies. However, the real star was the expansion of Zero-ETL Integrations. AWS enabled seamless, near-real-time replication from Aurora to OpenSearch and RDS to Redshift. By leveraging the database’s internal transaction logs, AWS…
AWS Monthly (July ’25): Kubernetes at the Edge of Sanity
July was a landmark month for the EKS (Elastic Kubernetes Service) crowd. AWS announced that EKS now supports 100,000-node clusters. While 100k nodes might be overkill for most of us, the technical optimizations required to make the Kubernetes control plane stable at that scale benefit everyone. The scheduler is faster, and ETCD performance is more…
