Is there a difference between your service and SpotInst aka Spot.io? Do you claim to have a better algorithm? It would be interesting to load the same app with both companies and see how the spend differs
From what we've heard, Spot by NetApp charges somewhere between 20% and 30% of the savings found. Vantage Autopilot charges 5% of the savings found.
We ultimately can't comment on their algorithms or effectiveness of Eco but the difference in these fees for what should be comparable savings found by both seems extreme. At Vantage, we try to philosophically align with the customer and pass on the highest amount of savings possible. Other providers seem to be doing the opposite.
