37signals To Delete AWS Account, Cutting Cloud Costs By Millions

37signals, a software firm, is migrating its 18 petabytes of data from AWS to Pure Storage arrays, expecting to save $1.3 million annually on storage costs. The upfront cost of the new infrastructure is $1.5 million, but it will only cost $200,000 yearly to operate. The company has already slashed $2 million in annual cloud compute costs by replacing it with $700,000 worth of Dell servers in 2024, and AWS waived $250,000 in data egress fees for the transition. The company's CTO, David Heinemeier Hansson, initiated the repatriation effort in 2022 after discovering their annual AWS bill exceeded $3.2 million.
