I'm curious about the realities of self-hosting message brokers, specifically RabbitMQ. I've been digging into the documentation and it seems quite complex, requiring a solid understanding across the OSI stack. However, it appears to be a popular self-hosted option. Has anyone here dealt with this? I'd love to hear any war stories, common oversights, or whether I'm overthinking the complexities involved in this.

Self-hosting is definitely feasible, but it all depends on your scale. Managing one cluster is one thing, but handling multiple clusters means you'll need dashboards, alerts, and possibly automations. It's all about how much you have to manage and what resources are available to you.
I've been self-hosting Kafka, and when it gets busy, it's crucial to remember that message brokers are bound by physical limitations. Disk I/O can be a bottleneck, so consider your storage options carefully. There's a tradeoff between disk speed and cost, and self-hosting can often be much more affordable than cloud solutions.
Make sure to keep an eye on your PVC space; it can fill up quickly and crash everything!
When it comes to scaling applications, message queues play a critical role. If you have enough budget, using a vendor service might be the best route, but building your own comes with performance constraints. Just remember, your dev and test environments need to mimic production to really be effective. It’s a balancing act between cost, performance, and understanding the infrastructure you're working with.
I left some details out intentionally to get a broader discussion. Have you seen more specific setups or broader organizational deployments?
