Self-Hosted PostgreSQL 17 NVMe VPS vs AWS RDS Multi-AZ: 12-Month IOPS & TCO Audit
AWS RDS charges steep premiums across four stacked dimensions: vCPU/RAM markup, Multi-AZ 2x duplication, provisioned EBS IOPS above the 3,000 baseline, and RDS Proxy per-vCPU fees. Modern NVMe VPS/VDS nodes with WAL-G + Patroni deliver higher raw 4K IOPS at ~12% of the monthly bill.

UltaHost Dedicated VDS vs Hostinger KVM NVMe VPS for PostgreSQL 17
Database latency p99 spikes come from two bottlenecks: shared hypervisor CPU steal (%st) during heavy queries and shared NVMe queue contention during checkpoints. Picking KVM vs VDS comes down to sustained concurrency and RAM ceiling.

Vultr High Frequency 3.8GHz+ NVMe vs Serverless Postgres (Neon / Supabase): Latency & Compute Bill
Serverless Postgres shines for ephemeral PR preview branches that sleep 22 hours a day. Once a production SaaS app receives steady 24/7 traffic or cron jobs prevent scale-to-zero, metered Compute Units (CU-hours) and cold page fetches from remote object storage become both slower and 4x costlier than always-warm 3.8GHz+ local NVMe.

InterServer Bare-Metal Ryzen + OpenZFS NVMe vs AWS EBS io2 Block Express for Multi-TB Postgres
Provisioning 2TB of high-durability AWS EBS io2 at 40,000 IOPS costs over $2,600/mo in storage & IOPS fees alone — before adding a single vCPU! Pairing InterServer Bare-Metal Ryzen 2TB NVMe ($89–$139/mo price-locked) with OpenZFS gives you atomic 8KB writes, 2.5x ZSTD compression, and instant copy-on-write snapshots.
