cloudflareworkersWorkers KV for Session State: An Architecture Note
Workers KV removes the origin round trip from session lookups, but its consistency model decides your logout behavior, your cache settings, and when you need Durable Objects instead.
cloudflareWhat k3OS Got Right About Immutable Infrastructure: A Look Back at config.yaml
k3OS is archived, but its one-file config.yaml model — where hostname, SSH keys, and Kubernetes cluster membership are all declared at boot — is still a design worth stealing for edge and lab clusters.

k3osK3s’ Embedded SQLite: When the Default Data Store Is Enough—and When It Isn’t
K3s ships with an embedded SQLite database that removes the need for an external etcd, but the single‑writer lock and lack of replication limit its use to single‑node or low‑write workloads.

sqlitek3OS's Declarative Config Was the Real Product — and Why It's Now a Design Study, Not a Platform
k3OS is archived, but its headline decision — an entire node defined by one versioned config.yaml — is still the right way to think about provisioning edge Kubernetes fleets.
Configuring Cloudflare Rate Limiting for API Protection: A Practical Guide
Set up Cloudflare Rate Limiting to guard your APIs from abuse while keeping legitimate traffic smooth. Learn how to choose between fixed‑window and sliding‑window algorithms, deploy granular rules, and verify effectiveness with built‑in dashboards and API exports.
Using Cloudflare Workers KV for Global Feature Flags
Learn how to use Cloudflare Workers KV to share mutable state like feature flags across all edge instances, with a concrete code example, trade‑offs, and a verification checklist.
Using Cloudflare Workers KV for Low‑Latency Global State: When to Trust It and When to Caution
Cloudflare Workers KV offers low‑latency global reads, but its eventual consistency and write limits mean you need to design for staleness and throttling. This guide walks through a counter example, shows how to bind KV, and explains when KV is a good fit.
