Isn't one of the big benefits of serverless functions being able to scale transparently? Can a kubernetes cluster give you anywhere near the elasticity of something like lambda?
- TheIronYuppie 10y agoBy and large, yes. However, the responsiveness is highly variable. Both pods and nodes can automatically scale, though it is intended that this is somewhat gradual, by design (you don't want to spin up 4000 nodes because you have a 30 second spike). Because the functions tend to be _very_ small, you can (likely) pack many of them together without having to scale. Disclosure: I work at Google on Kubernetes
- continuational 10y agoEven if it could spin up machines, you also need an auto-scaling database, and an autoscaling event infrastructure. otherwise it's not really serveless in any meaningful sense, since you'd then have to have separate, manually operated servers. Still, it's part of the puzzle.
