Is c8g.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.
Arm (Graviton) checklist
AWS Graviton4 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 (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$202
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 c8g.xlarge for about 15.6 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 c8g.xlarge costs about $136/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).

Questions
How much does c8g.xlarge cost per month in ap-southeast-1?
$134 on demand for Linux running all 730 hours, before storage, public IPv4 and data transfer.
Can AWS credits pay for c8g.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 c8g.xlarge?
A 1-year Savings Plan brings it to $0.1391/h and 3 years to $0.0949/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.
