Challenge	Twitch, the world’s leading social video platform and community for gamers, faced the challenge of managing an extremely high volume of concurrent users. With over 100 million community members and up to 2 million concurrent visitors, Twitch needed a robust solution to handle their website-wide chat functionality. The chat rooms often scaled up to 400,000+ users, requiring low latency and high availability to ensure a seamless user experience. Additionally, Twitch's engineering team sought operational simplicity and reliability to focus on delivering the best possible experience to their users. Read More
About Customer	Twitch is the world’s leading social video platform and community for gamers, bringing together over 100 million community members. The platform allows users to watch and talk about video games from over 1.7 million broadcasters. Twitch's engineering team is dedicated to providing extremely fast response times, high availability, and reliability for their web application. The platform is architected to handle incredible scale, with over 2 million concurrent viewers at peak times. Twitch uses several open-source technologies to manage their data backend, including Redis, Cassandra, Elasticsearch, and DynamoDB. Read More
Solution	To address their challenges, Twitch chose Redis Labs Enterprise Cluster (RLEC) to power their chat application. Redis was initially selected for its blazing fast performance, operational simplicity, and optimized data structures for rapid, high-scale data processing. As Twitch's infrastructure became more complex, they moved additional functionalities such as token caching and view counting from Cassandra to Redis. Redis Labs provided a managed service with VPC peering to Twitch’s infrastructure, which runs extensively in Amazon Web Services. This setup eliminated the need for Twitch to build operational expertise to manage Redis in production. Redis Labs Enterprise Cluster offered high availability, reliability, and minimal operational overhead, allowing Twitch to focus on enhancing their user experience. Read More Log in to view content
