Is c6i.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 8375C (Ice 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$211
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 c6i.xlarge for about 14.6 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 c6i.xlarge costs about $145/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: 1,250 Mbps and 6,000 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 $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).

Questions
How much does c6i.xlarge cost per month in ap-southeast-1?
$143 on demand for Linux running all 730 hours, before storage, public IPv4 and data transfer.
Can AWS credits pay for c6i.xlarge?
Yes. Activate credits cover on-demand EC2 usage. They don't cover upfront Reserved Instances or Savings Plan commitments.
Is a Savings Plan worth it for c6i.xlarge?
A 1-year Savings Plan brings it to $0.1488/h and 3 years to $0.1015/h. While credits last, on demand is usually better because credits can't buy the commitment.
Prices and credit amounts are estimates and may change. Check AWS for current terms.
