Deferred Revenue and Remaining Performance Obligations Deferred Revenue and Remaining Performance Obligations
Revenue recognized for the three months ended October 31, 2021 from amounts included in deferred revenue as of July 31, 2021 was $255.0 million. Revenue recognized for the three months ended October 31, 2020 from amounts included in deferred revenue as of July 31, 2020 was $121.2 million.

Revenue recognized for the nine months ended October 31, 2021 from amounts included in deferred revenue as of January 31, 2021 was $464.0 million. Revenue recognized for the nine months ended October 31, 2020 from amounts included in deferred revenue as of January 31, 2020 was $222.0 million.

Remaining performance obligations (RPO) represent the amount of contracted future revenue that has not yet been recognized, including both deferred revenue and non-cancelable contracted amounts that will be invoiced and recognized as revenue in future periods. The Company’s RPO excludes performance obligations from on-demand arrangements as there are no minimum purchase commitments associated with these arrangements, and certain time and materials contracts that are billed in arrears.

As of October 31, 2021, the Company’s RPO was $1.8 billion, of which approximately 75% was related to contracts with original terms that exceed one year. The weighted-average remaining life of the Company’s contracts with original terms that exceed one year was 2.4 years as of October 31, 2021. However, the amount and timing of revenue recognition are generally driven by customer consumption, which can extend beyond the original contract term in cases where customers are permitted to roll over unused capacity to future periods, generally upon the purchase of additional capacity at renewal.
