A Pulsar instance consists of one or more Pulsar clusters. Clusters, in turn, consist of a broker cluster, a bookkeeper cluster and a zookeeper cluster. While this provides a modular and flexible design, there is a lot of bytes flowing over the network. In an application that is paranoid about security that is a lot of connections, both intra cluster and inter-cluster, to secure. At nutanix we have deploy pulsar in a secure environment and run it through a lot of security audits for infrastructure certifications.

In this talks, we will go over how we set up authentication and authorization on all the network communications to make our pulsar deployment secure.
