Notice: STACKIT deprecated Redis (all versions) on August 1, 2026. Final decommissioning of all Redis instances is scheduled for August 1, 2027. As the successor, STACKIT provides the Key Value Store based on Valkey. For new projects we recommend starting with the Key Value Store directly.
What is STACKIT Redis?
STACKIT Redis is a fully managed in-memory data store based on the open-source Redis project. The service is suited for high-performance caching, session management, and real-time applications where data is kept in memory to achieve very low access times. STACKIT operates the service exclusively in German data centers for complete GDPR compliance.
Core Features
- Low latency through in-memory data storage
- Usable as a cache, database, or message broker
- Single-instance and replica-set configurations for different availability requirements
- Automatic recurring backups with multi-day retention
- Auto-updates and self-healing mechanisms
Typical Use Cases
Session Storage: Storing user sessions for high-traffic web applications with fast access.
Database Query Caching: Caching frequent database queries to offload relational databases such as PostgreSQL.
Leaderboards and Counters: Real-time rankings and atomic counter operations for view counts, likes, and similar metrics.
Benefits
- Complete data sovereignty in German data centers
- Managed service with automatic backups and patching
- Flexible scaling from single instance to multi-node replica set
- GDPR compliant with ISO 27001 certification
Migrating to the Key Value Store
Because Redis will be decommissioned on August 1, 2027, existing instances should be migrated to the STACKIT Key Value Store in good time. The Key Value Store is based on Valkey, the open-source fork of Redis, and is compatible with common Redis clients.
Integration with innFactory
As an official STACKIT partner, innFactory supports you with STACKIT Redis: assessing existing instances, planning and executing the migration to the Key Value Store, plus operations and cost optimization.
Available Tiers & Options
Single Instance
- Low latency
- Cost-effective
- No automatic failover
Replica Set
- Multiple nodes for higher availability
- Automatic backups
- Higher cost

Frequently Asked Questions
What is STACKIT Redis?
STACKIT Redis is a fully managed in-memory data store based on the open-source Redis project. It works as a cache, database, or message broker for applications with high performance requirements.
What persistence options does STACKIT Redis offer?
STACKIT automatically creates regular backups of the instance with multi-day retention. For details on client-side persistence options, refer to the core Redis documentation.
What is the difference between Redis and Memcached?
Redis offers complex data structures, pub/sub messaging, and replication beyond simple key-value caching. Memcached, by contrast, is specialized for straightforward key-value caching.
How does high availability work with STACKIT Redis?
In replica-set mode, STACKIT runs multiple nodes, each holding a full copy of the data. This increases availability compared to a single-instance configuration.
Is STACKIT Redis still available?
STACKIT deprecated Redis in all versions on August 1, 2026. Existing instances keep running, but final decommissioning is scheduled for August 1, 2027. For new projects and migrations, STACKIT provides the Key Value Store based on Valkey as the successor.
Is STACKIT Redis GDPR compliant?
Yes, STACKIT Redis runs exclusively in German data centers. STACKIT is ISO 27001 certified and offers a data processing agreement (DPA).
