Customer Stories

Migration from Cassandra:
Backup & restore on mobile app for 300M users
Almost 1 PB in DynamoDB, 130M daily API requests
Migrated from Cassandra to DynamoDB
Consistent performance and 70% cost savings (TCO)
DynamoDB provided consistent
high performance at a drastically
lower cost than Cassandra.”

Migration from MongoDB:
Stores data on over 125M patents in DynamoDB.
Benefits of migrating from MongoDB to DynamoDB:
1) Fast and stable response time with unlimited
capacity
2) Less time spent on maintenance, monitoring,
backups
3) Easy to manage scaling and security settings
4) 50% cost savings over our MongoDB cluster
Ruiying Wu
Head of Operations. PatSnap
“Thanks to DynamoDB, providing and updating
125M+ Patents from over 100+ countries requires
zero effort. DynamoDB provides very consistent
performance and scalability, thus we are capable of
making search and analysis usable and accessible to
non-IP experts, helping them innovate.

Migration from Oracle:
Every time you buy something on amazon.com, behind-the-scenes
coordinator: Herd - supports 100s of millions of active workflows
which need to start within a couple of seconds
Migrated from Oracle to DynamoDB:
1) Workflow processing delays dropped from 1s to 100ms
2) Scaling and maintenance effort dropped 10x
3) Retired over 300 Oracle hosts
Our internal customers saw processing delays decrease
from 1 second to 100 milliseconds; those latency
reductions ultimately translate into Amazon customers
getting their orders faster. That’s really a testament to the
performance of Amazon DynamoDB. It shows how it can
serve as the foundation of a highly efficient, mission-
critical system.”
