I know this has been announced earlier, but now that the AWS CEO announced a precise time frame, the whole matter looks more realistic. I can’t determine whether the Oracle leadership was too naive, thinking that this would never happen, or do they really have a blind belief in the products even though the reality is different. Either way, I think this could have been prevented, but now that it’s happened we will, without a doubt, have very damaging consequences, and not just in terms losing Amazon as a customer, but also by gaining a tough competitor on the market.
