> Server costs tend to scale well with your customer base. They used to, when they were your servers. Now that they're AWS's server, there can be a 10x price premium, which amplifies the problem introduced by provisioning for scalability at all costs. When it's nobody's job to worry about costs, it's very easy for them to tend to balloon out of control. Of course, there's not much point in worrying about a $1M cloud bill with $100M in the bank.
