The Cloud Messaging team at Verizon Media has been running a large installation of Pulsar in data-centers across the globe, since the inception of Pulsar. The system is run as a hosted platform to provide pub-sub messaging as a service for hundreds of use cases within Verizon Media. It hosts millions of topics in full mesh global replication, with automated on-boarding and resource management. In this talk, we share the operating experience in scaling Pulsar, its evolution over the last 5 years on multiple hardware configurations, tuning and capacity modeling practices. The talk will also cover the operating practices like rolling upgrades, automation and monitoring of the systems. Some of the important issues experienced in production and learnings will be discussed. We will also discuss some areas for operational improvements in Pulsar
