Reserver vs ProsperOps.
ProsperOps' own fee rises with the savings it finds, because that is the pricing model. Reserver charges the same flat monthly price whether it finds ten thousand dollars a year or ten million, and Reserver does not manage Azure or Google Cloud commitments.
What ProsperOps does well
A fair look at ProsperOps, from its own site.
ProsperOps continuously rebalances Reserved Instances and Savings Plans across AWS, Azure, and Google Cloud, adjusting coverage to real usage many times a day, and reports the result through its own savings-rate metrics.
How the pricing models differ
ProsperOps's own published pricing model.
A Savings Share model: a percentage of the dollar savings its automation generates, calculated from your cloud provider's own billing system, not a percentage of total cloud spend. A separate flat per-resource monthly fee applies to its workload-optimization product.
Reserver charges one flat monthly price at every tier. Watch is free, forever. Autopilot and Scale are flat monthly fees, never a percentage of what Reserver finds or buys.
The percentage tax
A cut of your savings is still a bill that grows.
Percentage-of-savings tools charge more the better your fleet does. Reserver's own fee is a sliver of what it finds: free on Watch, a few percent on Autopilot, and well under 1% of savings once a fleet reaches Scale. A percentage-of-savings vendor at the same size typically takes 25%.
Startup
1–10 reservations · a single account
Flat pricing keeps $2,633/yr in your pocket instead.
Growth
dozens of reservations · a few accounts
Flat pricing keeps $24,537/yr in your pocket instead.
Enterprise
hundreds to thousands · many AWS accounts & orgs
Flat pricing keeps $257,262/yr in your pocket instead.
These figures are illustrative. Savings use the same conservative model as the calculator, and the %-of-savings figure assumes a typical 25% rate. Reserver is a flat price and never takes a cut.
