• AWS re:Invent 2017: Snapchat Stories on Amazon DynamoDB (DAT325)
    • GCP appengine customer wanted to shift particular functional area over to dynamo
    • First experiment failed to reduce cost like they expected nor did it perform well
    • Failed experiment did give them insight into application changes they could make to reduce number of reads / writes and throughput
    • Saved millions of dollars after network, cpu cost savings
    • Tested in prod. They did dual writes for awhile. (Writes went to the old system and new)
