Redis has evolved from a caching and session storage solution into the primary database for high-performance stateful applications. Companies like Gap and Alliance Data have successfully implemented real-time applications at enterprise scale using Redis Enterprise, which provides fast database performance, easy-to-learn data structures, and operational simplicity across multiple data structures and modules. This has allowed them to improve customer experiences by optimizing fulfillment and shipping of online orders, quadrupling throughput, boosting application uptime, and onboarding customers they could not previously support.
