This article seems to be spreading some FUD, in particular this comment:
> Cloud economics – by design, Kafka’s replication strategy will rack up massive inter AZ bandwidth costs.
You're no more or less forced to put Kafka replicas in different AZs than you would be with an alternative.
- richieartoul 3y ago(WarpStream Founder) That's fair, but we think people shouldn't have to choose between multiple AZs and costs. All cloud providers recommend that critical workloads running in cloud environments should run in more than one AZ.
- crimsonpowder 3y agoOf course, as soon as an AZ goes down that had all of your Kafka nodes in it, you get eviscerated on HN for running such a setup.
- EdwardDiego 3y ago3 AZ Kafka is the safest, but I've run several 2.5 clusters just fine. (cluster stretched across 2 AZs with a tiebreaker ZK in a 3rd AZ to maintain quorum in the event that you lose an AZ)
