AWS Enterprise Agreement, Cloud Services
Loss Contingencies [Line Items]
Purchase commitment, description		In March 2016, we entered into the AWS Enterprise Agreement for the use of cloud services from Amazon Web Services, Inc. (“AWS”), which was amended in March 2016 and again in February 2017. The agreement will continue indefinitely until terminated by either party. Under the February 2017 addendum to the agreement, we committed to spend $1.0 billion between January 2017 and December 2021. That addendum was amended in October 2018, and we are now committed to spend an aggregate of $1.1 billion between January 2017 and December 2022 on AWS services ($90.0 million in 2018, $150.0 million in 2019, $215.0 million in 2020, $280.0 million in 2021, and $349.0 million in 2022). If we fail to meet the minimum purchase commitment during any year, we are required to pay the difference. Any such payment may be applied to future use of AWS services during the addendum term, although it will not count towards meeting the future minimum purchase commitments under the addendum.
