Is inf1.xlarge right for you?
What 8 GiB of RAM runs
- ✓ MVP backend with a few hundred users
- ✓ Single Docker service or small Kubernetes node
- ✓ CI runner, internal tools
- ✕ Large in-memory caches
- ✕ Production database with growing data
- ✕ Video or ML processing
Full-time CPU
No burst limits: all 4 vCPUs are yours 100% of the time, so it suits steady traffic, builds and background jobs.
x86 compatibility
Intel Xeon Platinum 8275CL (Cascade Lake) runs any x86 software unchanged. If your stack supports Arm, the Graviton version is usually around 20% cheaper.
About Asia Pacific (Singapore)
Hub for Southeast Asia. GPU capacity can be limited.
Moving data between availability zones costs about $0.01/GB each way.
The real bill for a small production setup
The server is rarely the biggest line. A typical setup behind a load balancer in a private network:
About per month$293
Load balancer: $0.0252/h plus about $0.40/month in usage for 1 million requests. NAT gateway: $0.059/h plus $0.059/GB processed. Moving data between availability zones adds $0.01/GB each way. Skip the NAT gateway with public subnets or VPC endpoints to save $43/month. Prices for Asia Pacific (Singapore) from the AWS Price List API (2026-10-19). Both are covered by AWS credits.
Credits expire before you can use them all
$25,000 would run one inf1.xlarge for about 9.3 years, but credits usually expire in 12 to 24 months. Spend the surplus on a managed database, staging environments or load testing instead of leaving it unused.
Credits pay on-demand and Spot usage, not upfront Savings Plan or Reserved Instance commitments. Buy commitments only once credits run low.
Database, disk and traffic
Managed database vs running it yourself
A managed PostgreSQL database (RDS db.t4g.medium, single zone, 20 GB) costs about $77.22/month in Asia Pacific (Singapore).
Running Postgres yourself on a second inf1.xlarge costs about $227/month, but you handle backups, upgrades and failover.
Both are paid by AWS credits. Upfront fees for reserved databases are not.
Sending 1 TB a month to users
Straight from the server: about $108/month ($0.12/GB after the first 100 GB).
Through CloudFront: $0. Server-to-CloudFront traffic is free and the first 1 TB out each month is free (then $0.12/GB for Asia Pacific edges).
RDS, CloudFront and transfer prices from the AWS Price List API; VPS prices from Hetzner and DigitalOcean, excluding VAT (2026-10-19).
