If it works then I would expect Amazon to acquire it so they can break it.
I’m not saying their pricing is not confusing, but the account managers and sales engineers I’ve worked with always did a good job navigating us through it - and being honest when something can be achieved a lot cheaper.
Better have a customer optimize their usage, pay less, be happy, and stick with AWS than switching to a different platform.
Full disclosure: I work at AWS. Not on CloudEndure or anything relating to pricing. But come on.
