Frequently asked questions about FlexSave for Amazon Web Services
FlexSave helps you maximize EC2 discounts with zero commitments, loss risk, or management on your part. It works by analyzing your on-demand workloads, and then applying the ideal mix of RIs and Savings Plans to them, optimizing for cost.
In order to use FlexSave, your AWS account/s should be consolidated with the DoiT International billing organization. DoiT International is a global AWS Advanced Channel Reseller.
How much can I save every month?
You can realize between 80% and 100% of the discount granted by the applicable AWS Reserved Instance 1-year Full Upfront.
For example, AWS grants a 19.5% discount on reserved instances for instances from the m5 instance family in the us-west-1 region. A FlexSave reservation for this machine/region combination will provide you with a 15.6% (19.5% * 0.8) discount but without the risk of committing to the entire year.
Can I use FlexSave if I am using AWS RIs or Saving Plans?
FlexSave reservations are applied to on-demand usage. Usage covered by AWS Reserved Instances or Savings Plans is excluded.
Which AWS services are supported with FlexSave?
At this time, FlexSave supports AWS EC2. Other AWS services such as AWS RDS, VMware or Elasticache aren't supported at this time. Since FlexSave relies on AWS Convertible Reservations, you can check supported instances on AWS website. If there are no Convertible Reservations available for your instance type, it's not supported with FlexSave as well.
Can I send a report to the CFO with the actual realized savings?
Your actual savings is displayed in your FlexSave Dashboard. Your CFO should have access to this dashboard if they have the FlexSave Admin permission, and would be able to monitor the utilization as well as the actual savings yielded by the FlexSave.
