Everything you need for production workloads

Lightning Fast

In-memory data storage with microsecond latency for ultra-fast read and write operations.

Persistent Storage

Optional data persistence with RDB and AOF for durability without sacrificing performance.

High Availability

Automatic failover and replication support to ensure your cache is always available.

Secure by Default

TLS encryption, password authentication, and network isolation to protect your data.

Real-time Monitoring

Detailed metrics for memory usage, operations per second, and connection statistics.

Kubernetes Native

Deployed on Kubernetes with automatic scaling and self-healing capabilities.

Pub/Sub Messaging

Built-in publish/subscribe for real-time messaging and event-driven architectures.

Multiple Engines

Choose between Redis, Valkey, or Dragonfly based on your performance requirements.

DNS Management

Common Use Cases

Optimize your applications with in-memory caching

🔧

Session Storage

Store user sessions with fast access and automatic expiration. Perfect for web applications with user authentication.

# Node.js example

const redis = require('redis');

const client = redis.createClient();

// Set session with 24h expiry

client.setex('session:123', 86400, JSON.stringify(userData));

⚡

API Caching

Cache API responses to reduce database load and improve response times for your users.

# Python example

import redis

r = redis.Redis()

# Cache API response for 1 hour

r.setex('api:/users', 3600, json.dumps(users))

Cache Frequently Asked Questions

Everything you need to know about managed caching

What's the difference between Redis, Valkey, and Dragonfly?

Redis and Valkey are single-threaded (1 CPU core). Dragonfly is multi-threaded, scaling from 1 to 8 CPU cores with our plans, delivering up to 25x higher throughput on a single instance.

Do you provide DNS management for cache instances?

Yes. Public cache instances get automatic DNS records like redis-{instance}.{tenant}.danubedata.ro or valkey-{instance}.{tenant}.danubedata.ro, updated if IPs change.

Do you support Redis clustering?

Larger cache plans support Redis clustering with automatic failover and high availability for production workloads.

How do I migrate from another Redis provider?

Most Redis-compatible apps migrate seamlessly. We provide tooling and support for zero-downtime migration assistance.

What's the data persistence like?

All cache engines support RDB snapshots and AOF persistence. Backup frequency and retention can be customized per instance.
