This is mainly in reference to the fact that Reserved Instances don't have any bearing on the instances themselves (ie. no code change, performance chance, server downtime, etc.).

The 57% savings is the difference between the 3-year, no-upfront, standard Reserved Instance rate and the On-demand rate (for RDS it is 30% vs on-demand)

As far as compute savings plans:

1-yr SP is anywhere from 26-29% savings vs on-demand

3-year Sp is anywhere from 49-52% savings vs on-demand

... but note that these commitments are non-transferrable. Customers find our tailorable commitments to be a healthy blend of savings + safety against over-committing to volume they may not need

I like to say we're a marketmaker for cloud contracts. Our recommendations take our current inventory into account and it's been very effective considering the amount of 'trades' we successfully make each day. That aside, We also have a considerable amount of cash set aside for an event like this.

For now we're all-in on AWS, but have plans on going to Google Cloud later this year!
