KeyDB on Ubuntu 24.04 LTS

KeyDB on Ubuntu 24.04 LTS by cloudimg

KeyDB is a high-performance fork of Redis that is fully protocol- and command-compatible but uses multiple threads to drive higher throughput from a single node. It is a drop-in replacement for Redis for caching, session stores, queues, rate limiting, leaderboards and pub/sub. The cloudimg image installs KeyDB 6.3.4 (the official keydb-server and keydb-cli), runs it as a dedicated keydb system user, stores RDB snapshots and the AOF append-only log on a dedicated Azure data disk, and rotates a unique password into the image on first boot. Backed by 24/7 expert support.

Multithreaded and Redis-compatible

KeyDB speaks the Redis protocol, so existing Redis clients, libraries and tooling work unchanged. It runs with server-threads 2 to use both vCPUs of a Standard_B2s for higher throughput than single-threaded Redis on the same hardware.

Dedicated Data Disk

RDB snapshots and the AOF append-only log live on a dedicated, independently resizable Azure data disk mounted at /var/lib/keydb, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up your keyspace.

Secure By Default

KeyDB is bound to loopback only (127.0.0.1:6379) and is not exposed publicly. Authentication uses a single shared password (requirepass) that is unique to each VM, generated on first boot and stored in a root-only file. Reach KeyDB over an SSH tunnel (ssh -L 6379:127.0.0.1:6379 azureuser@your-vm-ip) or bind it to a private NIC with TLS for remote use.
