Heroku Postgres · $21000/mo (768 GB RAM, 6144 GB)
Heroku Shield-XL-9 at $21,000/mo is significantly overpriced for enterprise Postgres. Linode's managed database offers comparable specs at half the cost with better uptime SLA, though you'll need to budget for HA clustering and backups. Oracle's serverless option is dramatically cheaper but requires careful capacity planning and separate storage billing.
512GB RAM and 7200GB NVMe storage at less than half Heroku's price with 99.99% SLA vs Heroku's undisclosed reliability.
Caveat: Add ~$2,215-2,768/mo for HA clustering (2-3x multiplier) and ~$2,215-2,768/mo for backups to match enterprise requirements, bringing true cost to $15,500-16,100/mo.
Before you switch
| Provider | Plan | Price | Specs | |
|---|---|---|---|---|
| Oracle Cloud Infrastructure | Autonomous Database (ATP/ADW) · Serverless - 1 ECPU | $245.28/mo | 1 vCPU | Visit |
| Linode (Akamai) | Managed Databases · Dedicated G7 512 GB - Standalone | $11073.6/mo | 512 GB RAM, 112 vCPU, 7200 GB NVMe | Visit |
Extreme cost reduction with serverless auto-scaling and 99.95% SLA, suitable if workload is bursty or development/test.
Caveat: 1 ECPU is roughly 0.5 OCPU capacity and cannot handle Shield-XL-9 production workloads; storage billed separately at $0.0257/GB/month; you would need to scale up significantly, negating savings advantage.
