ShareChat, India's largest social media company, successfully migrated over 150 services to Dragonfly Cloud, achieving a 40% reduction in costs and improved performance without encountering any downtime. The decision to switch from Redis to Dragonfly was driven by the need for a scalable, low-latency, and cost-efficient solution that could handle the company’s rapid growth and varied workloads. Dragonfly's multi-threaded architecture offered better price-performance and resilience compared to Redis, allowing ShareChat to use fewer resources while maintaining lower P99 latency. The migration process was meticulously planned and executed over an 8-week period, with key principles such as zero downtime, drop-in compatibility, and parallel migration by application teams. The use of Redis Shake for data replication and Prometheus for monitoring facilitated a smooth transition. This modernization has not only reduced infrastructure complexity but also enabled ShareChat's engineering teams to focus on developing new features, ultimately delivering faster and more stable services to users.
