Alaska Airlines makes shopping easier
"We wanted to use Azure Cache for Redis and getting that running on-premises wasn't easy. But in Azure, with three clicks, we had it. We didn't have to coordinate with other teams to set up new infrastructure and figure out how to maintain it once we hit production, and that's a beautiful thing."
Ralph Feltis, Senior Software Engineer, Alaska Airlines
CarMax drives online innovation
"Azure PaaS (platform as a service) gave us access to a complete set of capabilities such as Azure Cache for Redis that we didn't have to build ourselves. We can spin up these services and start using them in less than an hour, which is incredible."

Frequently asked questions about Azure Cache for Redis
-
Azure Cache for Redis is a fully managed, in-memory cache that enables high-performance and scalable architectures. Use it to create cloud or hybrid deployments that handle millions of requests per second at sub-millisecond latency—all with the configuration, security, and availability benefits of a managed service.
-
While most databases store data on slower, disk-based storage, Azure Cache for Redis stores data in memory. Since memory is significantly faster than disk storage, data can be written and retrieved much faster.
-
In some cases—and often in session store use cases—Azure Cache for Redis can be used as a standalone database. However, most of the time, it is best used as a complement to a database in the form of a cache. Azure Cache handles data that needs to be accessed more frequently, while the database handles data that needs to be stored for the longer term.
-
Azure Cache for Redis offers exceptional reliability with a 99.9 percent SLA. Most tiers provide a built-in replica that acts as a failover if the primary instance goes down. You can also configure your Azure Cache for Redis instance to use data persistence to recover data in the event of a hardware failure.

1Performance claims are based on data from a study commissioned by Microsoft and conducted by GigaOm in October 2020. The study compared the performance of a test application using an Azure database with and without implementing Azure Cache for Redis as a caching solution. Azure SQL Database and Azure Database for PostgreSQL were used as the database element in the study. A 2 vCore Gen 5 General Purpose instance of Azure SQL Database and a 2 vCore General Purpose instance of Azure Database for PostgreSQL were used with a 6 GB P1 Premium instance of Azure for Redis. These results were compared with 8, 16, 24, and 32 vCore Gen 5 General Purpose instances of Azure SQL DB and 8, 16, 24, and 32 vCore General Purpose instances of Azure Database for PostgreSQL without Azure Cache for Redis. The benchmark data is taken from the GigaOm Web Application Database Load Test which simulates a common web application and backend database barraged by increasing HTTP requests. Actual results may vary based on configuration and region.
