Billing, Pricing & Support Plans
Difficulty: easy
Overview
Understanding AWS pricing and support options is essential for cost management and getting the right help.
AWS Pricing Principles:
- Pay-as-you-go — Pay only for what you use, when you use it.
- Save when you commit — Reserved Instances and Savings Plans offer discounts for usage commitments.
- Pay less by using more — Volume discounts; tiered pricing for S3, data transfer, etc.
- Benefit from AWS's scale — AWS passes economies of scale savings as price reductions over time.
EC2 Pricing Models Summary:
- On-Demand — Full price; no commitment; best for unpredictable workloads.
- Reserved Instances (1 or 3 yr) — Up to 72% savings; specify instance type + region.
- Compute Savings Plans — Up to 66% savings; flexible across instance family, size, OS, region.
- Spot Instances — Up to 90% savings; interruptible; best for fault-tolerant workloads.
- Dedicated Hosts — Physical server for your exclusive use; BYOL; highest cost.
