Live patching is cool but it's something of a mythical beast. I hear lots of people talking about the wonders of live patching but very few people reporting on actually using it in their own production systems. If you're building an ultra-reliable system, then you have to somehow make it robust in the case where (some of) the hardware executing your code fails. Once you've covered that case, there's not much need for live patching.
- macintux 4y agoI think it depends on which level of live patching you're talking about. At Basho, we would load module fixes into Riak instances for customers...I hesitate to say "fairly regularly" because it's been long enough and I had limited visibility into it, but it certainly seemed like a routine operation. The full "upgrade the entire application" hot loading definitely requires more planning than most companies will ever be willing to do.
