- There are three fundamental drivers of cost with AWS:
- Outbound data transfer.
- AWS offers pay-as-you-go for pricing.
- For certain services like Amazon EC2, Amazon EMR, and Amazon RDS, you can invest in reserved capacity. With Reserved Instances, you can save up to 75% over equivalent on-demand capacity. When you buy Reserved Instances, the larger the upfront payment, the greater the discount.
- With the All Upfront option, you pay for the entire Reserved Instance term with one upfront payment. This option provides you with the largest discount compared to On-Demand instance pricing.
- With the Partial Upfront option, you make a low upfront payment and are then charged a discounted hourly rate for the instance for the duration of the Reserved Instance term.
- The No Upfront option does not require any upfront payment and provides a discounted hourly rate for the duration of the term.
- There are also volume-based discounts for services such as Amazon S3.
- For new accounts, AWS Free Tier is available.
- Free Tier offers limited usage of AWS products at no charge for 12 months since the account was created. More details at https://aws.amazon.com/free/.
