The story described Dropbox moving "34 PB of analytics data (Hadoop)" to AWS.
My reading of Dropbox's Magic Pocket / Diskotech appears to be storage for customer raw data -- similar to BackBlaze type of raw storage.
It's 2 different use cases so it's not surprising Dropbox found AWS to be effective for analytics workloads. AWS has an extensive portfolio of software services to analyze data so Dropbox may have concluded paying AWS would cost less than reinventing the analytics pipeline in-house.
