Heroku Postgres · $12500/mo (768 GB RAM, 5120 GB)
Heroku Premium-L-9 is significantly overpriced for its specs. Linode's Managed Database offers comparable or superior hardware at 11% lower cost with better SLA and no tier-cliff reliability gotchas. Oracle's serverless option is a poor fit for this workload size but worth mentioning for cost-conscious teams willing to accept architectural constraints.
512GB RAM and 112 vCPU for $1,426/mo less; NVMe storage is faster than Heroku's SSD; 99.99% SLA vs Heroku's unspecified uptime avoids the Essential-tier reliability cliff.
Caveat: Standalone (no HA) at this price; HA 3-node cluster costs 2-3x more; backups and outbound bandwidth are separate line items; verify your workload fits 7200GB disk vs Heroku's 5TB.
