Is r7g.medium 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 1 vCPUs are yours 100% of the time, so it suits steady traffic, builds and background jobs.
Arm (Graviton) checklist
AWS Graviton3 is usually 20% cheaper than the x86 equivalent for similar speed.
Build Docker images for linux/arm64 (or multi-arch). Node, Python, Go, Java and Ruby run fine; check native modules and closed-source agents.
About Asia Pacific (Tokyo)
For Japan; one of the pricier Asian regions.
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$117
Load balancer: $0.0243/h plus about $0.40/month in usage for 1 million requests. NAT gateway: $0.062/h plus $0.062/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 $45/month. Prices for Asia Pacific (Tokyo) 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 r7g.medium for about 44.2 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 $76.49/month in Asia Pacific (Tokyo).
Running Postgres yourself on a second r7g.medium costs about $49.08/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 $103/month ($0.114/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 $0.114/GB for Japan edges).
RDS, CloudFront and transfer prices from the AWS Price List API; VPS prices from Hetzner and DigitalOcean, excluding VAT (2026-10-19).
