Redis is an in-memory data platform that stores and retrieves data at high speed, making it ideal for applications requiring real-time performance. It serves use cases including caching, session management, message queuing, leaderboards, fraud detection, and vector search for AI applications. _Source: [https://redis.io](https://redis.io)._ ### Is Redis open-source or commercial? Redis offers both options: Redis Open Source is free and available under an open-source license (version 8.0 and later uses a tri-license model with RSALv2, SSPLv1, or AGPLv3). For commercial users, Redis Inc. provides Redis Cloud (fully managed) and Redis Software (self-managed on-premise), both with paid plans. _Source: [https://github.com/redis/redis](https://github.com/redis/redis)._ ### What programming languages and platforms does Redis support? Redis provides official client libraries for Python, Node.js, Java, Go, and .NET, plus numerous community-maintained libraries for other languages. This wide language support makes it compatible with most modern development stacks. _Source: [https://redis.io](https://redis.io)._ ### What data types does Redis support? Redis supports a wide range of data types including strings, lists, sets, sorted sets, hashes, streams, JSON, geospatial indexes, time-series data, and vector sets. This variety enables developers to optimize for different use cases from simple key-value storage to complex AI vector search. _Source: [https://redis.io/docs/latest/develop/data-types/](https://redis.io/docs/latest/develop/data-types/)._ ### How can you deploy Redis? Redis offers three deployment options: Redis Open Source for self-managed on-premise installations, Redis Software for self-managed hybrid deployments, and Redis Cloud for fully managed cloud hosting on AWS, Azure, or Google Cloud. This flexibility allows organizations to choose based on their infrastructure and operational preferences. _Source: [https://redis.io](https://redis.io)._ ### What is the pricing model for Redis Cloud? Redis Cloud operates on a tiered model with a free tier (limited to 30 MB), an Essentials tier starting from $5 per month for shared deployment, and a Pro tier (minimum $200 per month) for dedicated deployment with multi-region capabilities. Pricing is based on data size, with option to pay hourly or commit to monthly plans. _Source: [https://redis.io/pricing/](https://redis.io/pricing/)._ ### What are common alternatives to Redis? Common alternatives include Memcached for simple caching, database caching layers, key-value stores like DynamoDB or MongoDB, and message brokers like Apache Kafka. The choice depends on whether the primary need is ultra-fast caching, persistent storage, complex queries, or message streaming. _Source: [https://redis.io](https://redis.io)._ ### Does Redis provide persistence and data reliability? Redis offers optional persistence through snapshotting and append-only file (AOF) logging, though its primary design prioritizes speed via in-memory storage. For critical data, users typically pair Redis with a persistent database or use Redis Cloud's backup features. Advanced plans on Redis Cloud provide up to 99.999% uptime SLA with active-active multi-region deployment. _Source: [https://redis.io](https://redis.io)._ ## Facts Every value below carries its source and our confidence.
