Learn how Cloudflare Workers KV can turn a stateless edge function into a fast, globally‑replicated cache. The post walks through a real example, explains the write‑once/read‑many pattern, and highlights when KV isn’t the right tool.
Durable Objects give you a single-threaded, SQLite-backed actor at the edge with WebSocket hibernation. This post walks through a real-time collaboration counter, shows the billing mechanics, and highlights the trade-offs you'll hit in production.
Secure Boot and TPM give k3OS a hardware root of trust, preventing unsigned kernels or modules from running. This post walks through enabling the feature, verifying it, and the trade‑offs you’ll encounter in edge deployments.
Learn how to boot k3OS from a USB stick with a persistent data volume, configure a lightweight k3s cluster on embedded hardware, and understand the trade‑offs and practical steps for reliable edge deployments.
K3s replaces etcd with SQLite by default, saving memory and operational overhead on edge devices. This post explains why that works, when it breaks, and how to migrate to PostgreSQL for HA — with a concrete step-by-step example.
Running untrusted third-party code close to users needs isolation without process overhead. WebAssembly linear memory plus capability-based imports gives a bounded sandbox with controlled host access.
Learn how to manage remote Docker hosts behind NAT and firewalls using Portainer's Edge Agent architecture to eliminate inbound port requirements.
k3OS makes k3s nodes reliable at the edge by using an immutable read-only root with a writable overlay and image-based atomic updates, forcing configuration to be declarative instead of ad-hoc.
Stop opening firewall ports for remote Docker management. Learn how Portainer Edge Agents use outbound TLS tunnels to manage distributed hosts securely.
