A comment on There are very few suitable use cases for DynamoDB. Parent comment
Here are some of DynamoDB customers describing their use cases:
- DataXu: "How DataXu scaled its System to handle billions of events with DynamoDB" -- https://youtu.be/lDiI0JMf_yQ?t=765 (from AWS re:Invent 2016)
- Lyft: “Lyft Easily Scales Up its Ride Location Tracking System with Amazon DynamoDB” -- https://www.youtube.com/watch?v=WlTbaPXj-jc. The story "AWS Helps Fuel Lyft's Expansion" in InformationWeek mentions Lyft's use of DynamoDB as well: http://www.informationweek.com/cloud/infrastructure-as-a-ser...
- Under Armour implemented cross-region replication using DynamoDB: https://youtu.be/NtaTC2Fq7Wo?t=699
- Amazon.com: Amazon Marketplace shares their story of migration to DynamoDB: https://www.youtube.com/watch?v=gllNauRR8GM
Finally, DynamoDB was created because Amazon needed a highly reliable and scalable key/value database. As Werner Vogels said it in his blog post announcement of DynamoDB back in 2012 (http://www.allthingsdistributed.com/2012/01/amazon-dynamodb....):
"This non-relational, or NoSQL, database was targeted at use cases that were core to the Amazon ecommerce operation, such as the shopping cart and session service."
