Understanding AWS Pricing Models

AWS offers several pricing models for EC2, each with different cost implications:

1. On-Demand Instances

Pay for compute capacity by the hour or second with no long-term commitments. Best for:

• Users with unpredictable workloads
• Applications being developed or tested
• Short-term, spiky workloads that can’t be interrupted

2. Reserved Instances

Purchase capacity for a 1 or 3 year term with significant discounts (up to 75%) compared to on-demand. Three payment options:

• All Upfront: Full payment at purchase for maximum discount
• Partial Upfront: Partial payment at purchase with remaining balance over term
• No Upfront: No initial payment, discounted hourly rate over term

3. Spot Instances

Bid on unused EC2 capacity at steep discounts (up to 90%). Best for:

• Flexible start and end times
• Applications that can withstand interruptions
• Urgent computing needs for large amounts of additional capacity

4. Savings Plans

Flexible pricing model offering low prices in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1 or 3 year term. Two types:

• Compute Savings Plans: Apply to any instance family in any region (up to 66% savings)
• EC2 Instance Savings Plans: Apply to a specific instance family in a region (up to 72% savings)

Real-World Cost Comparison

The following table compares monthly costs for different instance types and purchasing options (based on us-east-1 pricing as of Q3 2023):
