Is r7g.large right for you?
What 16 GiB of RAM runs
- ✓ Production API with steady traffic
- ✓ Self-hosted Postgres or Redis
- ✓ Several containers on one host
- ✕ Tiny side projects (you'll overpay)
- ✕ GPU-bound AI workloads
Full-time CPU
No burst limits: all 2 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 South America (Sao Paulo)
Best latency for Brazil but one of the most expensive regions. Many teams serve Brazil from us-east-1 instead.
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$226
Load balancer: $0.034/h plus about $0.55/month in usage for 1 million requests. NAT gateway: $0.093/h plus $0.093/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 $68/month. Prices for South America (Sao Paulo) 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.large for about 16.7 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.r7g.large, single zone, 20 GB) costs about $282/month in South America (Sao Paulo).
Running Postgres yourself on a second r7g.large costs about $127/month, but you handle backups, upgrades and failover.
Both are paid by AWS credits. Upfront fees for reserved databases are not.
Disk speed limits
Steady disk speed: 630 Mbps and 3,600 IOPS.
Short bursts up to 10,000 Mbps and 40,000 IOPS, for about 30 minutes a day, then it drops back.
A busy database or heavy file processing may hit this limit before CPU or memory.
Sending 1 TB a month to users
Straight from the server: about $135/month ($0.15/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 $0.11/GB for South America edges).
RDS, CloudFront and transfer prices from the AWS Price List API; VPS prices from Hetzner and DigitalOcean, excluding VAT (2026-10-19).
