## Apache Pulsar on Ubuntu 24.04 LTS by cloudimg

Apache Pulsar is the open-source, cloud-native distributed messaging and event-streaming platform that combines high-throughput pub-sub messaging with durable, tiered storage. It separates serving from storage using Apache BookKeeper, supports multi-tenancy and geo-replication, and exposes a rich admin REST API. The cloudimg image installs Apache Pulsar 4.0.11 LTS on OpenJDK 17 at /opt/pulsar and runs it in standalone mode (ZooKeeper, BookKeeper and the broker in a single process) as a dedicated pulsar system user. The official Apache Pulsar Manager web console is fronted by an nginx reverse proxy on port 80, the broker and manager data live on a dedicated Azure data disk, and a unique admin password is generated on the first boot of every VM. Backed by 24/7 expert support.

Dedicated Data Disk

The BookKeeper ledgers and journal, ZooKeeper metadata and the Pulsar Manager database live on a dedicated, independently resizable Azure data disk mounted at /var/lib/pulsar, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up your topics and persisted messages.

Secure By Default

The Pulsar Manager admin password is unique per VM and stored in a root-only file, regenerated on the first boot of every VM. The broker admin REST and the Pulsar Manager backend bind to loopback and nginx fronts the console with a second wall of HTTP Basic auth, so only port 80 is exposed. Restrict the broker client port 6650 to trusted networks and add TLS for production.
