OUR CLOUD-EXIT SAVINGS WILL NOW TOP TEN MILLION OVER FIVE YEARS

Summary from the TLDR newsletter

37signals brought its cloud bill down from $3.2 million a year to $1.3 million by pulling seven cloud apps out of AWS and into its own hardware. Its expenditure on all new hardware has been entirely recouped. Most of the $1.3 million spend is still on AWS S3 - the company's cloud storage contract doesn't expire until next summer and it plans to stop using AWS when the contract expires. Moving completely away from AWS is expected to save the company another $4 million over five years.
