Hetzner CX22 vs AX41 in 2026: €4.50 Cloud VM vs €45 Bare Metal for Your Self-Hosted PaaS
A Hetzner CX22 cloud VM costs €4.50 with 20TB included; an AX41 dedicated box costs €45 with 64GB RAM and 1TB NVMe but no API. A head-to-head spec table, worked monthly math for 1/3/10-node fleets, and a checklist for when plain Docker beats Cluster API.
MetalLB vs kube-vip on Bare Metal: The Two-Day Hetzner Outage That Settled a Fleet's Load Balancer Choice
Hetzner's 44-hour Ashburn load balancer outage took down every fleet that trusted a managed L4. A practical comparison of MetalLB and kube-vip on bare metal — their failover behavior, BGP needs, and why a Cluster API fleet on dedicated hardware should run both in different roles.
Power-Bound, Not GPU-Bound: Why the Grid — Not the Chip — Is the 2026 Bottleneck
Gartner says 40% of AI data centers hit a power wall by 2027. With 24–36-month grid queues, 700W H100s, and 140kW racks, the grid — not the GPU — is the 2026 bottleneck. Here's what that means for a CPU-only Hetzner fleet.
When us-east-1 Goes Dark: What One AWS Region Under Your Whole Stack Really Costs
AWS us-east-1's 15-hour DynamoDB DNS outage in October 2025 broke Ring, Reddit and United check-in at once. A worksheet prices that failure for small, mid and large teams, maps how hosted PaaS silently inherits us-east-1, and compares the bill to a three-location Hetzner fleet under Cluster API.
CAREN Meets Flux: Composable Runtime Hooks for Day-2 Cluster API Without Custom Controllers
CAREN turns Cluster API day-2 operations into composable Runtime SDK hooks — CNI, CCM, CSI, and LoadBalancer GC sequenced through blocking lifecycle callbacks. A concrete walkthrough of wiring CAREN into a CAPH ClusterClass and closing the loop with Flux GitOps.
Chaos-Test Your Cluster API Fleet: Three LitmusChaos Experiments That Prove Self-Healing Before 3 A.M. Does
MachineHealthCheck promises your fleet self-heals — but few teams have watched it happen. A runnable LitmusChaos suite for CAPH/CAPD fleets: kill a kubelet, partition a control plane, fill a disk — and assert remediation fires within nodeStartupTimeout, workloads reschedule, and the fleet converges without a human.
Zero Egress, Metered State: What Cloudflare's January 2026 Durable Objects Bill Actually Costs Against a Flat Hetzner Box
Cloudflare's zero-egress promise still holds for R2 and CDN — but SQLite-backed Durable Objects started billing $1/M writes and $0.20/GB-month on January 7, 2026, with Workflows steps following August 10. A worked table prices small, medium and heavy stateful workloads against a €3.79 Hetzner CX22 with flat 20TB and local Postgres.
Eleven Minutes, Zero Humans: What Kairos's Self-Healing Upgrades Teach a Bare-Metal PaaS
A CNCF Kubestronaut ran an 11-minute, zero-human Kubernetes upgrade on Kairos's A/B immutable OS — and documented every bug that almost broke it. Here is the pipeline, the two fixes that saved etcd quorum, and how to translate it to a Hetzner + Cluster API fleet.
The EU Just Legislated Who Can Sell Cloud to Its Governments: What CADA's Four Tiers Mean for Your PaaS Choice
On June 3, 2026 the EU turned its SEAL-0 to SEAL-4 sovereignty grades into procurement law. A concrete map of CADA's four assurance levels, where US hyperscalers hit a structural wall, and why a fleet on owned Hetzner/OVHcloud/Scaleway hardware clears a bar a US-headquartered PaaS cannot.
