We work with a client who has requested a Kafka cluster. They can’t really say why, or what they need it for, but the now have a very large cluster which doesn’t do much. I know why they want it, same reason why they “need” Kubernetes. So far they use it as a sort of message bus.

It’s not that there’s anything wrong with Kafka, it’s a very good product and extremely robust. Same with Kubernetes, it has it uses and I can’t fault anyone for having it as a consideration.

My problem is when people ignore how capable modern servers are, and when developers don’t see the risks in building these highly complex systems, if something much simpler would solve the same problem, only cheaper and safer.
