RDBMS Migration from Mainframe:
• Retail business ran on mainframe—
a bottleneck for developers
• Migrated financial transaction data to
DynamoDB
• Unbound scale for app developers
“We built a secure and resilient cloud infrastructure
that could solve the scalability and reliability problems
with a serverless architecture.”

RDBMS Migration from MySQL:
Serving more than three billion GIFs a day to more than 300 million dail
active users.
Migrated from MySQL to DynamoDB:
• MySQL had a scaling bottleneck
• DynamoDB automatically scales as the business grows
• Improvement in read responsiveness by 25%, and overall system
performance
“For any company experiencing rapid user growth, scaling data
can be a hard and daunting task. In our case, Amazon RDS with
a DynamoDB/DAX solution was the perfect combination to
alleviate our growing pains.”
