Frequently Asked Questions
How accurate are these estimates?▼
These estimates are based on on-demand pricing for major instance types and may differ from actual bills due to: reserved instances/savings plans (up to 72% discount), spot instances (up to 90% discount), egress costs, storage I/O, support plan charges, and regional pricing differences. Use as a planning baseline, then refine with your specific pricing agreement.
What is the difference between reserved and on-demand pricing?▼
On-demand: pay per hour, no commitment. Reserved Instances (1-year, no upfront): typically 40% cheaper. Reserved (3-year, all upfront): up to 72% cheaper. Savings Plans: more flexible than reserved instances, apply across instance families. For predictable, steady-state workloads, reserved or savings plans dramatically reduce costs.
How do I estimate data transfer costs?▼
Data transfer within a region (AZ to AZ) is typically $0.01/GB. Transfer to internet: first 1GB free, then $0.09/GB (AWS), $0.12/GB (Azure), $0.08/GB (GCP). Using a CDN (CloudFront, Azure CDN, Cloud CDN) reduces egress costs significantly. Egress is often the surprise on cloud bills.
When should I use spot/preemptible instances?▼
Spot (AWS), Preemptible (GCP), and Spot VMs (Azure) offer 60-90% discounts but can be interrupted with ~2 minutes notice. Good for: batch processing, CI/CD runners, ML training jobs, dev/test environments. Not suitable for: production databases, stateful services, or any workload that can't handle interruption.
