3. Pricing Options-that add up to maximum flexibility and savings for AWS users As the AWS technology platform has become more and more robust, scale has enabled AWS to operate more efficiently and continue to lower prices a number of times, Selipsky said. In addition to passing on the benefits of scale in the form of lower pricing, AWS has a range of pricing options to choose from.Amazon Elastic Compute Cloud (EC2) pricing options include:On-Demand Instances On-Demand Instances let users pay for compute capacity by the hour with no long-term commitments or upfront payments. Users can increase or decrease their compute capacity depending on the demands of their application and only pay the specified hourly rate for the instances they use. On-Demand Instances are recommended for:
- Users who want the low cost and flexibility of Amazon EC2 without any upfront payment or long-term commitment
- Applications with short-term, spiky or unpredictable workloads that cannot be interrupted
- Applications being developed or tested on Amazon EC2 for the first time
- Applications with steady state or predictable usage
- Applications that require reserved capacity, including disaster recovery
- Users able to make upfront payments to reduce their total computing costs even further
- Applications that have flexible start and end times
- Applications that are only feasible at very low compute prices
- Users with urgent computing needs for large amounts of additional capacity
- Backed with the Amazon S3 Service Level Agreement (SLA).
