Precision Exams delivers online academic exams and is focused on the U.S. high-school market in all 50 states. The company needed to scale its database to ensure a low-latency testing experience, regardless of the volume of testing happening at any particular moment. By moving to Amazon DynamoDB from a custom MySQL database, Precision Exams can scale to meet the needs of its customers—whether it’s 100 or 1,000 reads per second. The company also reports saving 30 percent of the cost of running the database.
