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&#x2F;sec but still in the process of migrating many more applications. We run on top of kubernetes (EKS).<p>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.<p>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.<p>Ask me anything in thread and will try and answer questions. At some point we will do a blog post on our experience.
