Real-time applications require real-time solutions to meet customer expectations for speed. Redis Enterprise is an in-memory database that provides the speed and performance necessary for real-time use cases compared to traditional SQL databases. Caching user session data, APIs, and other parts of the data lake into Redis Enterprise can transform your data layer and enable real-time applications. Data ingestion methods like blue-green deployments, multi-phase migrations, legacy systems integration, hybrid cloud architectures, geo-distributed on-demand infrastructure, and CQRS pattern implementation using Redis Connect help maintain consistency between legacy and new databases while enabling real-time data use cases.
