So... the news here is that GCP seems to be significantly slower in practice, where all three products are priced at the same spot. But... the weird question is why are the Azure financials funny? The listed prices are about the same, but the "annual cost" for Azure seems to include a "41% off" discount that I can't find an explanation for? And then they use the latter in the calculation of price efficiency, which seems... what? This is the kind of thing Comcast does in its marketing. What is that discount and what's the justification for assuming that all users get it in perpetuity?
