Redis
Specific characteristics

Redis, benchmarked as the world’s fastest database, reduces application complexity, simplifies development, accelerates time to market and provides unprecedented flexibility to developers with its visionary data structures and modules.

Redis Labs is the home of open source Redis and commercial provider of Redis Enterprise, the in-memory database platform for transactional, analytics and hybrid deployments. Redis Enterprise is available, both as a service in major public, private and hybrid clouds, as well as downloadable software.

Competitive advantages

Redis is an in-memory database platform offering native support of wide range of data structures such as strings, hashes, sets, lists, sorted sets, bitmaps, hyperloglogs, and geospatial indexes. Redis Modules extend the capabilities of Redis transforming it into a multi-model database. With Redis Modules, one can use Redis as a search engine, time-series database, graph database, JSON store, rate limiter, and more.

Redis Enterprise increases the power of Redis with an enhanced deployment architecture that includes a zero latency distributed proxy, a cluster manager, and a shared-nothing cluster architecture. It offers:

  • Effortless scaling in a fully automated manner by overseeing all the operations of sharding, re-sharding, migration
  • A high availability suite including persistence, instant automatic failure detection, backup and recovery, and in-memory replication across racks, zones, datacenters, regions, and cloud platforms.
  • Substantial cost savings with built-in multi-tenancy, greater efficiency in hardware utilization, support for flash as a RAM extension
  • ACID controls for transactions in a clustered environment
Typical application scenarios

Redis powers personalization, real-time fraud detection, IoT, e-commerce, real-time metering, and social applications among many solutions. It’s use cases range from caching, high-speed transactions, time-series logs, message broker, real-time analytics, data ingestion, to job and queue management, and more.

Licensing and pricing models

The licensing model is subscription based. Redis Enterprise Cloud is priced according to data capacity (both fixed and pay-as-you-go plans are available), whereas Redis Enterprise Software is licensed according to the number of shards (Redis processes) in a cluster. Redis Enterprise is also available inside VPCs of major cloud vendors, and is priced by number of shards in such an environment. Redis Enterprise Cloud offers a free-for-life tier that's limited to a single database of up to 30MB. Redis Enterprise Software is available as a free download for trial.
