Give Your Agents a Memory That Lives on Your Machines: Qdrant vs Weaviate vs pgvector
AI agents without persistent memory re-derive everything on every run. A number-backed comparison of the three self-hostable vector stores — plus the per-tenant scale ladder that picks pgvector as the default and Qdrant as the escape hatch.
One Cluster for Training and Inference: How a Bank Cut AI Token Costs 60% on Kubernetes
China Merchants Bank won the CNCF End User Case Study Contest for running AI training and inference on a single Kubernetes stack of nearly 10,000 accelerator cards — lifting utilization from 35% to over 60% and cutting inference cost per million tokens by more than 60%. The component-by-component breakdown, the fairness rules behind it, and what smaller self-hosted fleets can copy.
E2B's $150/Month Sandbox Meter vs a $70 Hetzner Box: What Agent Sandbox-Hours Really Cost
E2B bills agent sandboxes per second on top of a $150/month Pro plan; a Hetzner box you own runs the same Firecracker isolation for a flat $70. A worked recompute across three team sizes shows where the meter wins, where the flat box wins by 10x, and why E2B's CPU-only ceiling settles the GPU question before pricing does.
eBPF Ate the Sidecar: What Hubble, Pixie, and Coroot Actually Replace on a Self-Hosted Fleet
67% of Kubernetes teams at scale already run eBPF observability. The sidecar-per-pod telemetry model costs ~250MB RAM per pod and milliseconds per request — a per-node kernel agent replaces it at a fraction of the cost. What Hubble, Pixie, and Coroot each replace, and which one a team that patches its own stack should run.
Europe's Sovereign GPU Price Table: The Two Break-Evens That Decide Rent-vs-Own Inference
Hetzner rents H100s at ~$2.80/hr and OVHcloud at ~$3.20/hr, neither sells H200 time, and a $989/month dedicated box beats both past ~45% utilization. The full table, the math, and why sovereignty is a discount here.
Railway vs Vercel vs Cloudflare: What Bursty Builds Really Cost Per Second (and When a Flat Hetzner Node Wins)
Railway, Vercel, and Cloudflare all bill per second but meter different things. A worked recompute at three burst tiers shows where metered builds beat a flat Hetzner node — and where they quietly lose.
Valkey Won the Default: What a git-push PaaS Should Bundle Now That the Redis Fork Became the Safe Choice
Two years after Redis gave up the BSD license, Valkey is the default on major Linux distros and the recommended engine on ElastiCache at 20-33% lower prices. A cost-vs-gain accounting for making it your platform's standard cache, plus the one boundary where Redis still wins.
Your AI Budget Will Be Wrong. Your Deploy Bill Doesn't Have to Be
Enterprise surveys say four out of five teams miss their AI spend forecasts. Model inference is inherently unpredictable — but the deploy bill underneath it is a choice. Here is why agent-operated apps belong on flat-rate machines you own.
Cloudflare Sandboxes Are GA: Active-CPU Billing vs E2B/Daytona, Repriced Line by Line
Cloudflare's GA Sandbox pricing bills CPU only while it burns and memory while the container stays awake. We run 30,000 bursty agent sessions through the rate card against E2B, Daytona, and Modal, find the break-even near 62% CPU-active, and name what the math can't change: it only runs on Cloudflare.
