Valkey

Valkey is a powerful, open-source alternative to Redis, offering full compatibility with Redis clients while providing an independent development path focused on community-driven innovation. Deploy and manage Valkey in Zerops' fully managed infrastructure to get instant access to high-performance in-memory data storage.

Tip

Valkey is our recommended Redis alternative as KeyDB's development has slowed significantly in recent times.

Supported Versions

Currently supported Valkey versions:

• 7.2

Import configuration version:

• valkey@7.2

Service Configuration

Zerops offers Valkey in two deployment configurations to meet different availability requirements.

Non-HA Setup

• Single node deployment on port 6379 (non-TLS) and 6380 (TLS)
• No backup mechanism beyond Zerops infrastructure reliability
• Data persists unless the hardware node fails
• Suitable for development or non-critical workloads

HA (High Availability) Setup

Our HA implementation uses a unique approach to ensure high availability while maintaining compatibility with all Redis clients:

• 3-node configuration (1 master + 2 replicas)
• Access ports:
  • 6379 - read/write operations (non-TLS, routed to master)
  • 6380 - read/write operations over TLS (routed to master)
  • 7000 - read-only operations (non-TLS)
  • 7001 - read-only operations over TLS
• Implementation details:
  • All nodes are configured identically and listen on standard ports
  • First node in the cluster is designated as the master
  • On replica nodes, ports 6379/6380 traffic is forwarded to the master
  • Ports 7000/7001 are mapped locally to each node for direct replica access
  • When a master fails, a replica is promoted and routing is updated automatically
  • DNS entries are updated for seamless client connection
  • This implementation provides traffic forwarding to master (not natively supported by Valkey)

Note

Be aware that replica data may lag slightly behind the master due to asynchronous replication.

Trusting the TLS certificate

The certificates served on the TLS ports (6380 and 7001) are signed by the Zerops Certificate Authority. To verify them from outside Zerops, download and trust the Zerops CA — e.g. redis-cli --tls --cacert ./zerops-ca.pem -h <ip> -p 6380.
