Heroku Is Gone: We Re-Ran Encore's Exit Map With Real Bills for Render, Railway, Fly.io, and Hetzner
Encore's Heroku exit map points refugees at Render, Railway, Fly.io, and a VPS. A line-by-line re-audit prices the same stack on each — quiet month and traffic-spike month — and finds the meter shape matters more than the headline number.
DRA or HAMi? What Actually Shares Your GPUs in 2026
Kubernetes DRA now handles the scheduling half of GPU sharing, but runtime enforcement still belongs to HAMi. Here is the converged architecture, the concrete migration path, and which layer each fleet shape should standardize on.
Heroku's Fir Can't Deploy Your Dockerfile: a Migration Playbook With Real Before-and-After Bills
Heroku's Fir generation can't deploy Docker images and Cedar entered sustaining mode in February 2026. A migration playbook for container teams: what breaks on Fir, how Render, Railway, and Fly.io handle Dockerfiles, and one typical stack priced five ways — $87 on Heroku, ~$35–60 hosted, ~$7 self-hosted.
Heroku Is in Sustaining Mode: When to Migrate and What Render, Railway, and Fly.io Really Cost
Heroku's February 2026 sustaining-mode announcement closed the door on new Enterprise contracts and froze new features. A timing framework for when to leave, a five-way cost table for the same workload on Heroku, Render, Railway, Fly.io, and Hetzner hardware, and where each alternative actually fits.
TCPRoute Went Stable, but Somebody Still Has to Own the IP: kube-vip vs Talos BGP vs Hetzner LBaaS
Gateway API 1.6 made TCPRoute portable, but something still has to announce the IP. A worked comparison: kube-vip ARP is free but LAN-bound, Talos BGP is free but needs a peer, and Hetzner LBaaS costs ~€7.49 per TCP service — €37 at five services, €150 at twenty.
All or Nothing: What Kubernetes v1.36's PodGroup Scheduling Buys a Self-Hosted PaaS That Packs Tenants Tight
Kubernetes v1.36 gives kube-scheduler native all-or-nothing gang placement plus rack-aware co-location. A mini-fleet walkthrough shows what that saves a self-hosted PaaS bin-packing tenants onto fixed nodes — and the alpha limits that say don't run it in production yet.
One GPU, Two Tenants: Where DRA, MIG, vCluster, and DCGM Share a Card — and Where the Trust Boundary Says Stop
CNCF's AI-factory guide lists DRA, MIG, vCluster, and DCGM as one stack. A concrete two-tenant design for a self-hosted fleet — which layers can share a single GPU within one trust domain, and why untrusted tenants still need whole cards or dedicated nodes.
Open-Weight AI's Kubernetes Moment: Stress-Testing the Analogy Phase by Phase
Tobi Knaup argues open-weight AI sits where Kubernetes sat in 2016. We grade the analogy across all four phases of the Kubernetes decade — substrate, distro fight, hyperscaler absorption, and the self-hosting price — with the utilization math that decides it.
Scale Before the Spike: Predictive GPU Pre-Warming for a Cluster API Fleet Without the Always-On Bill
Reactive autoscaling leaves a roughly 45-minute gap between an inference spike and ready GPUs. A concrete pre-warm design for a Cluster API fleet — request-side forecast signals, a measured boot budget, and a capped warm reserve — priced against Hetzner's monthly GPU boxes.
