Redis
Specific characteristics

The Redis real-time data platform builds upon the unmatched simplicity and speed of Open-Source Redis along with an enterprise grade data platform that offers robustness of modern data models, management, automation, performance and resiliency to deploy and run modern applications at any scale from anywhere on the planet. It provides a single data source for multi-model and sub-millisecond performance at any scale, anywhere: on-premises, private, public, and multicloud. Redis is the most used real-time database on the planet designed for continuous analytics, search, machine learning, and artificial intelligence.

Competitive advantages

Redis Enterprise is a robust in-memory database platform built by the people who develop open source Redis. It maintains the simplicity and high performance of Redis, while adding many enterprise-grade capabilities, such as linear scaling to hundreds of millions of operations per second, Active-Active geo-replication with local latency, Redis on Flash to tier data across dynamic and persistent memory and solid-state disk (SSD) to reduce total cost of ownership, and five-nines (99.999%) uptime based on built-in durability and single-digit-seconds failover. 

Redis Enterprise can be deployed as a software on-premises, fully managed service over public clouds (Google Cloud, AWS, Azure), or in multicloud and hybrid architectures to avoid vendor lock-in. 

Redis offers Strings, Hashes, Lists, Sets, Sorted Sets, Bitmaps, Bitfields, HyperLogLog, Geospatial indexes, and Streams as native data structures. For every data structure, Redis maintains dedicated commands to allow execution of multi-type operations in an effective manner. 

Redis Enterprise supports many data modeling methods with modules such as RediSearch, RedisJSON, RedisGraph, RedisTimeSeries, RedisBloom, and RedisAI, and allows operations to be executed across and between modules and core Redis functionality using RedisGears, a serverless engine that runs across shards and nodes of Redis Enterprise cluster. All this while keeping database latency under one millisecond, so your application can respond instantaneously.

Typical application scenarios

Redis Enterprise is used by large enterprise, startup, and government organizations to power use cases such as real-time fraud detection, global user session management, real-time inventory management, feature store for AI/ML, claims processing, and more.  

Common use cases include (but not limited to):

  • Caching

  • High-speed transaction

  • Data ingest

  • Distributed messaging

  • Real-time analytics

  • Rate limiting 

  • De-duplication
