Duolingo HAQM DynamoDB Case Study

Duolingo uses HAQM DynamoDB to store 31 billion items in support of an online learning site that delivers lessons for 80 languages. The U.S. startup reaches more than 18 million monthly users around the world who perform more than six billion exercises using the free Duolingo lessons. The company relies heavily on HAQM DynamoDB not just for its highly scalable database, but also for high performance that reaches 24,000 read units per second and 3,300 write units per second. In addition, Duolingo uses a range of other AWS services such as HAQM Elastic Compute Cloud (HAQM EC2) based on the latest Intel Xeon Processor Family, for compute HAQM ElastiCache to increase performance; HAQM Simple Storage Service (HAQM S3) for storing image-related data; and HAQM Relational Database Service (HAQM RDS) for permanent data storage. Moving forward, Duolingo plans on leveraging AWS Elastic Beanstalk and AWS Lambda for its microservices architecture, as well as HAQM Redshift for its data analytics.
