Frequently Asked Questions
What persistence modes does STACKIT Redis offer?
STACKIT Redis supports RDB (snapshots) for periodic backups and AOF (Append-Only File) for continuous logging. Both modes can be combined.
What is the difference between Redis and Memcached?
Redis offers persistent storage, complex data structures, pub/sub messaging, and replication. Memcached is only optimized for simple key-value caching.
How does replication work with STACKIT Redis?
STACKIT Redis uses master-replica replication with Redis Sentinel for automatic failover. The High Availability tier provides multiple replicas across availability zones.
Is STACKIT Redis GDPR compliant?
Yes, STACKIT Redis operates exclusively in German data centers. SSL/TLS encryption and encryption-at-rest are available. STACKIT is ISO 27001 certified.
