Asana has filed to go public and, in the process, disclosed its commitment to Amazon’s AWS as its cloud platform of choice.

Popular collaboration tool Asana filed to go public this week. Asana is the brainchild of Facebook co-founder Dustin Moskovitz and Justin Rosenstein, a former Facebook and Google engineer.

What’s more interesting than Asana’s IPO, however, is the disclosure of its cloud budget and where it is spending that budget. Business Insider delved into the paperwork and discovered that Asana has agreed to spend at least $20 million on AWS cloud services.

“Asana in December 2018 agreed to a 27-month contract with AWS, committing to spend at least $9 million on cloud services in 2019, and an additional $11 million in 2020,” wrote Business Insider. “The company had $5.4 million left to spend to fulfill the minimum as of April 30 of this year.”

As the cloud market continues to heat up, with AWS, Microsoft and Google fighting for dominance, this is a big win for AWS.
