Deep Dive into Azure Cache for Redis: A Developer’s Guide

Azure Cache for Redis

Scale performance easily and economically as app needs and traffic grow. With the advantages of a fully managed service, handle thousands of concurrent users with near-instantaneous performance by adding a fast cache layer to the application design.

  • Better speed and throughput to manage millions of requests per second with latency as low as sub-milliseconds.
  • You can concentrate on development with Azure’s fully managed service that has automated patching, updates, scalability, and provisioning.
  • RedisJSON, RedisTimeSeries, RedisBloom, and RediSearch module integration, enabling data streaming, search, and analysis.
  • Strong features include Redis on Flash, clustering, active geo-replication, and up to 99.999 percent availability.

What can be constructed using Azure Cache Redis

Reduce latency and increase application performance

To speed up your data layer via caching, use Azure Cache for Redis. At a reasonable cost, adding Azure Cache for Redis may boost latency performance by over 1,000 percent and enhance data throughput by over 800 percent. It’s a fantastic method for quickly scaling apps and enhancing user experience without paying for a costly database redesign.

Applications may run faster using a distributed cache

Provide your data layer with the ability to extend throughput at a cheaper cost than with larger database instances, complementing database services like Azure SQL Database and Azure Cosmos DB. By using a common cache-aside structure, you may store and exchange session states, static content, and database query results while improving the nimbleness and scalability of your application.

Effectively store session information

Save, retrieve, and update web session data such as output pages and user cookies quickly. Enhance your application’s responsiveness and capacity to manage growing loads with less web-computing resources to improve performance. To maximize user data dependability, take use of data permanence and automated data duplication. To satisfy the demands of even the biggest companies, use clustering to scale up to terabyte sizes and synchronize session data worldwide with active geo-distribution.

Act as an intermediary for messages between services

To develop queue or publish/subscribe structures, use Azure Cache for Redis. Send messages in real time and expand online communication frameworks like SignalR. For data in transit, use industry-standard TLS encryption, and set up appropriate network isolation using Azure Private Link.

Boost app performance on Azure with Redis Enterprise

With Azure Cache for Redis’s Enterprise and Enterprise Flash tiers, which were created in collaboration with Redis Inc., you can get revolutionary support for well-liked Redis Enterprise capabilities. To build globally distributed caches with up to 99.999% availability, use active geo-replication. Utilize the RediSearch, RedisBloom, and RedisTimeSeries modules that come with the package to add new data structures that improve analytics and machine learning. And run Redis on fast flash storage by using the Enterprise Flash tier, which offers huge cache sizes at a cheaper cost.

Savor Redis as a completely managed solution

Use an Azure fully managed service to expedite deployment. Redis data structures, such as hashes, lists, and sorted sets, are natively supported by Azure Cache for Redis, which is powered by the open-source Redis software. Azure Cache for Redis is compatible with applications that utilize Redis. Import and export Azure Cache for Redis database files to expedite the migration process.


Leading supplier of in-memory data storage solutions, Redis, announced today a change to its open-source licensing policy. Redis is switching from the BSD 3-Clause License to a dual-license approach, allowing developers to choose between the first-ever Server-Side Public License (SSPLv1) and the second-ever Redis Source Available License (RSALv2).

Azure Cache for Redis lets you utilize a safe open-source cache. Microsoft’s dedicated solution provides rapid data access to construct highly scalable and responsive applications. Redis’ comprehensive feature set and ecosystem are combined with Microsoft’s trustworthy hosting and monitoring.


What steps must I take in order to utilize Azure Cache for Redis?

The impending Redis license changes will not impact Azure Cache for Redis, including Azure Cache for Redis Enterprise and Enterprise Flash. Users may utilize the service without any action.

RSALv2: What is it?

Redis has provided a permissive, non-exclusive, royalty-free license known as RSALv2, or Redis Source Available License 2.0, which allows the usage, distribution, and modification of certain software components created to operate with Redis, subject to the terms and restrictions specified in the agreement.

SSPLv1, what is it?

With a changed Section 13, the SSPL is a variation of the GNU Affero General Public License (AGPL). Any organization providing software under SSPL license as a service is required to make available all of the service’s source code, which includes management, user interfaces, APIs, automation, monitoring, backup, storage, and hosting software. This way, users can use the provided source code to run their own instances of the software.

Is the license for RSALv2 and SSPLv1 still valid for Azure Cache for Redis?

No, clients may only use Azure Cache for Redis in accordance with Microsoft’s terms of service. The usage of Azure Cache for Redis is not subject to the RSALv2 and SSPLv1 licenses.

Will updates and bug fixes for my Azure Cache for Redis instance be provided going forward?

Indeed, even after the aforementioned license announcement, updates and bug fixes will still be available for Azure Cache for Redis, Azure Cache for Redis Enterprise, and Enterprise Flash.

Will the Redis version that is available change as a result of Azure Cache for Redis?

The basic community versions of Redis and Redis Enterprise will still be supported by Azure Cache for Redis, Azure Cache for Redis Enterprise, and Enterprise Flash.

In light of this license news, what steps do I as an Azure Cache for Redis client need to take?

As of right now, our Microsoft and Azure clients are not needed to take any action in relation to the license announcement.
