Egress is the line item nobody sizes upfront and everyone regrets at month-end. Here's the taxonomy, the surprise bills, and what actually cuts it.
Datadog's bill has a way of tripling the quarter you actually start using it. Here are eight alternatives we've run in production and what each one costs you.
Edge functions run everywhere and remember nothing. Durable Objects give you one addressable, single-threaded instance with transactional storage — the missing source of truth.
The metrics stack you self-host is free software plus a real ops bill. Datadog hands you everything and mails you the invoice. Here's how we pick.
AWS gives you four ways to pay for compute and three of them cut the bill. Here is how to pick, and how to stack them without painting yourself into a corner.
A field guide to the OSS observability stack in 2026, sorted by pillar, with honest notes on where self-hosting pays off and where the ops burden bites.
How pods can talk to AWS, GCP, and Azure with no static keys — using audience-bound projected ServiceAccount tokens and the cluster OIDC issuer.
Both promise to find your slow query at 3am. One bills by data ingested, the other by host-hour. Here's how that shakes out in a real ops budget.
One vendor sends the invoice, the other sends the ops work. Here's how we pick between Datadog and the Grafana stack without regretting it later.
We ripped every client secret out of our CI pipelines by pointing Azure federated credentials at GitHub's OIDC issuer. Here's the exact setup and the claims that trip people up.
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.
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.
