Cloud Cost Optimization Tips

Use Reserved Instances

Commit to 1-3 year terms to save 30-60% vs on-demand pricing on AWS, GCP, and Azure.

Right-Size Instances

Most workloads use <20% of allocated CPU. Downsize to the next smaller instance type and monitor performance.

Use Spot/Preemptible

For fault-tolerant batch workloads, spot instances cost 70-90% less. Use for CI/CD, ML training, and data processing.

Optimize Data Transfer

Egress fees add up. Use CDNs, keep services in the same region, and compress data before transfer.

Frequently Asked Questions

How accurate are these estimates?

These are approximate on-demand prices based on typical US region pricing. Actual costs vary by region, OS, licensing, reserved instance discounts, and usage patterns. Always verify with the provider's official pricing calculator.

What is on-demand vs reserved pricing?

On-demand pricing is pay-as-you-go with no commitment — highest price but maximum flexibility. Reserved instances require a 1 or 3-year commitment but save 30-60%. Spot/preemptible instances use spare capacity at 70-90% discount but can be interrupted.

What is included in data transfer costs?

Most providers charge for outbound data (egress) from their network to the internet. Inbound data is usually free. Data transfer between services in the same region is typically free or very cheap. Cross-region and cross-AZ transfer has additional costs.

Which cloud provider is cheapest?

It depends on your workload and region. GCP tends to be slightly cheaper for compute, Azure has strong discounts for Microsoft workloads, and AWS has the widest service catalog. Use this calculator to compare for your specific requirements.

Should I include storage in my cost estimate?

Yes — storage costs are often underestimated. Block storage (EBS/Persistent Disk) runs $0.08-$0.10/GB/month. Object storage (S3/GCS) is $0.018-$0.023/GB/month. For data-heavy apps, storage can exceed compute costs.
