Apache Pulsar is an open-source distributed pub-sub messaging system
I just finished rolling out Pulsar to 8 AWS regions with geo-replication. Messages rates are currently at about 50k msgs/sec but still in the process of migrating many more applications. We run on top of kubernetes (EKS).It took about 5 months for our implementation with a chunk of that work mostly about figuring out how to integrate our internal auth as well as a using hashicorp vault as a clean automated way to get auth tokens for an AWS IAM role.Overall, we are very pleased and the rest of the engineering org is very excited about it and planning to migrate most of our SQS and Kinesis apps.Ask me anything in thread and will try and answer questions. At some point we will do a blog post on our experience.
