This is a huge ROI. Borrowing $25m costs about $1.25m/yr so you're winning even with no upfront costs
- valiant55 2y agoI mean, ideally you are still employing those people into the future. Plus was there other opportunities to drive value that would've been better spent?

- sokoloff 2y agoThat math assumes the on-going maintenance of LedgerStore is no higher than that of using DynamoDB was. I suspect there's now a team of technologists maintaining, securing, and operating LedgerStore.
- shawabawa3 2y agoI suspect they already had a team maintaining/debugging/operating dynamodb Hosted services doesn't reduce maintenance costs to zero
- sokoloff 2y agoThey have teams maintaining/debugging/operating their use/consumption of dynamodb; they don't have teams maintaining/debugging/operating/securing dynamodb itself. With LedgerDB, they now have to do both.
- shermantanktop 2y agoOptimizing to address high percentile issues (latency/error/correctness) on someone else’s code follows a bimodal pattern: it’s easy until it is impossible. Doing it on your own code is progressively more difficult and the complexity may cause you to give up, but you normally don’t hit the same wall.
- johannes1234321 2y agoQuestion is: Where else could they have spent those $25m? Could they have built something with more value? Opportunity cost is a cost, too
- shawabawa3 2y agoif at uber's scale they still have enough opportunities of that scale for every one of their thousands of engineers i need to buy some of their stock
