Disney+ Hotstar: Migrating to ScyllaDB Cloud For Predictable Low Latencies

Disney+ Hotstar, originally launched as Hotstar and later rebranded in March 2020, experienced rapid growth in subscriptions, reaching over 300 million users, including both paid and ad-supported tiers. The service set a record for concurrent streaming during the 2020 India Premier League cricket competition. To enhance user experience and manage data effectively, Disney+ Hotstar transitioned from using Redis and Elasticsearch to ScyllaDB Cloud, a decision driven by the need for consistently low latencies and cost-effectiveness. The migration process involved careful data handling, including converting existing data formats and ensuring synchronization with ScyllaDB. This shift allowed Disney+ Hotstar to maintain high performance and scalability without the administrative overhead of their previous systems, enabling them to focus on business growth.
