Running your own PaaS and infrastructure on machines you own
Java 27 Is GA: G1 Everywhere, Quantum-Safe TLS, and Goodbye Intel Macs — Your Buildpack TODO List
Java 27 turned on G1, compact object headers, and hybrid post-quantum TLS by default while ending Intel Mac maintenance. Here is what each change means for a self-hosted PaaS Java buildpack, with container memory math and a build-fleet checklist.
Kubernetes 1.36 In-Place Pod Resize Goes Beta: What Restart-Free Vertical Scaling Replaces in a PaaS Autoscaler
Kubernetes 1.36 graduates in-place vertical scaling for pod-level resources to beta: the kubelet can now grow a running pod's CPU and memory budget without a restart. This post shows the resize operation, the before/after for a PaaS autoscaler, and the beta caveats to clear first.
MCP Memory Servers: What Persistent Memory-as-a-Tool Means for a Deploy Agent That Forgets Every Session
MCP memory servers give deploy agents persistent memory any client can share — last good deploys, environment preferences, and incident fixes recalled by retrieval instead of replayed history. The catch: multi-tenant isolation and poisoned-memory attacks that turn one bad fact into a standing prompt injection.
10,000+ MCP Servers in Production: What the 2026 Numbers Say About Treating MCP as Infrastructure, Not a Toy
MCP has crossed 10,000 public servers and 97 million monthly SDK downloads — but benchmarks show the stdio transport collapsing at 20 concurrent connections while Streamable HTTP holds 100% success. This breakdown turns the 2026 numbers into a production checklist: stateless transport, backpressure, real-path health checks, OAuth, and a load-test recipe for deploy and rollback tools.
Nine Years in Beta Is Over: What Kubernetes 1.37's Stable Metrics API Means for Your Autoscaler
Kubernetes 1.37 promotes the metrics.k8s.io API to stable after nearly nine years in beta. What the frozen contract changes for autoscaling and usage metering on self-hosted clusters — plus the HPA gotcha and everything the API still doesn't do.
One CLI Command to a Full Remote Stack: What Moniepoint's Crossplane-Built Dev Environments Cost to Build Versus Buy
Moniepoint's eshu turns Score YAML into a full remote stack with one CLI command via Crossplane composition functions. The architecture, the two hard lessons (render-cycle steady state, 63-character names), and the build-vs-buy math: building wins past roughly 17 developers.
Your Kubernetes Cluster Already Negotiates Post-Quantum TLS. Your Edge Probably Doesn't
Kubernetes v1.33 already negotiates hybrid post-quantum TLS on the control plane — but your ingress, tenant certificates, and secrets layer each need their own verdict. A layer-by-layer readiness inventory with the CNSA 2.0 deadlines that set the pace.
PostgreSQL 18's Async I/O on Owned NVMe: What io_uring Reads, uuidv7, and a CNPG Upgrade Path Mean for Operator-Owned Postgres
PostgreSQL 18's async I/O can nearly triple cold-read speed — but only on workloads that touch disk, on nodes that pass a short kernel and seccomp checklist. Here are the numbers, the checklist, and a CNPG upgrade runbook measured against Railway's one-click button.
Qovery's September 2026 Price Table Says Render $7, Railway $5, Fly.io $2.02 — Here's the Second-Year Bill It Hides
Qovery's September 2026 comparison lists Render from $7, Railway from $5, and Fly.io from $2.02 — but a typical production app bills 9–17x those headlines by month twelve. A line-by-line second-year ledger for all three, plus the flat Hetzner box.
