The three big clouds are closer on list price than the sales decks suggest. Where they actually diverge is discounts, egress, and Windows licensing.
Edge runtimes look like Node but aren't. Here's what actually breaks — CPU caps, no filesystem, no TCP sockets — and how we route around it.
We've run both in production for years. Here's the honest split on pricing traps, tracing quality, and which one you actually want for your team size.
We ran both across a few hundred services. One wins on auto-instrumentation and root-cause, the other on breadth and time-to-first-dashboard. Here's the split.
The daemon error almost never means Docker is broken. Nine times out of ten it's a stopped service, a stale context, or a wrong env var. Here's the checklist.
Your pod is stuck because the node can't pull the image. Here's how to read the events, find the real reason, and fix each one fast.
A RAG system that invents facts erodes trust fast. Here is how we ground answers, force citations, and catch the fabrications before users do.
We've shipped production pipelines on both. Here's where GitHub Actions wins, where GitLab CI wins, and how to pick without regretting it in six months.
Long-lived access keys are the root cause behind most cloud breaches. This is the complete map to keyless auth — how workload identity federation and OIDC replace static secrets everywhere, and where to start.
Moving our fleet from x86 to Graviton promised 20% savings. We got 31%, but only after fixing native dependencies, a broken base image, and one nasty perf regression.
Our best engineer quit citing on-call. We rebuilt the whole thing: saner rotations, runbooks that actually help at 3am, and escalation that doesn't punish asking for help.
We ran secrets three different ways across AWS, GCP, and Vault. External Secrets Operator gave us one Kubernetes-native workflow. Here's the setup and the gotchas.
