- note: The 10-K names AWS as a public cloud provider Workday uses. Workday's applications have run on AWS infrastructure since a 2016 multi-year partnership, and in 2024 the companies expanded the partnership to use Amazon Bedrock and SageMaker for generative-AI feature development. The 10-K does not disclose vendor-specific spend. Separately, the 10-K discloses $1,056 million in aggregate FY2027-2029 purchase obligations for "third-party hosted infrastructure platforms" without naming a vendor, so whether any of that figure is attributable to AWS is unconfirmed (see open_questions).
