Or, to put it more plainly: “What Makes an Enterprise AI System Production-Ready, and Why Most Never Get There.” The answer most teams don’t want to hear is that a production-ready AI system has very little to do with how good the model is. What decides whether a system ships or stalls is the reliability, […]

Just over two years ago, I launched the Now Go Build CTO Fellowship with nine technology leaders working in disaster management and climate resilience. Since then, the program has grown to 24 Fellows from 18 countries across four continents, tackling problems in healthcare, education, and food security. Today, we’re releasing the second season of our […]

A couple of editions ago I wrote about what I find so energizing about working with startups. Last week I got a fresh dose of it: I spent a few days with the AWS Startups team, listening to stories of founders talking about the problems they’re actually solving. One story that stayed with me came […]

Managed service providers have long relied on recurring revenue from software licensing and cloud subscriptions to drive growth. While those revenue streams remain important, the channel is placing greater emphasis on services that deliver deeper customer value and support stronger long-term profitability. Microsoft recently highlighted this shift in its 2025 State of the Partner Ecosystem […]

Upgrading a Kubernetes control plane has long been a one way door. Open source Kubernetes doesn’t support control plane rollback, so once you upgrade, there’s no going back. The community is making real progress here, and KEP-4330 introduces emulated versions to ease rollback. But in practice this constraint has pushed organizations to build elaborate compensating […]

In reality, most teams make this decision too quickly and often default to preservation because it feels safer. However, preserving logic that is not understood does not reduce risk; it merely shifts it. The uncertainty moves from COBOL to Java, and the advantage of a proven mainframe environment is lost. The key question is whether […]

Today, we’re announcing AWS CloudFormation Express mode, a new deployment mode that accelerates deployments for developers and AI tools iterating on infrastructure. Express mode accelerates deployments by completing when CloudFormation confirms resource configuration is applied, rather than waiting for extended stabilization checks. This reduces deployment time by up to 4 times for iterative development workflows and […]

When you run compute-intensive workloads like real-time analytics, batch processing, video encoding, scientific modeling, or CPU-based machine learning inference, every percentage point of performance matters. You need instances that deliver higher throughput per vCPU, faster memory access, and more network bandwidth, all while keeping your costs in check. Today I am happy to announce the […]

If you manage TLS certificates for your applications, you know the challenge: certificates expire, and when they do, your customers see errors or your service goes down. As certificate validity periods get shorter (the Certification Authority (CA)/Browser Forum mandates reduced maximum validity to 100 days starting March 2027, and to 47 days by 2029), manual […]

When I joined Amazon, Jeff had an idea: no team should be so large that it couldn’t be fed by two pizzas. In those early days, some teams were so small that one pizza would’ve been enough to get the job done. But it was never really about feeding hungry engineers. We could’ve just as […]
