so basically this is a gui abstraction over "kubectl apply -f scaledObject.yaml" ...

It is a single place for installation, updates, security fixes and the whole administration of KEDA across the whole fleet of k8s clusters. Very soon there will be configuration optimization and recommender, dynamic scaling policies and much more. And yeah, also gui abstraction over `kubectl...` is there :)

Who needs autoscaling? I mean this as a serious question. Has somebody a real story where autoscaling helped out the company or product? If you have the hardware resources, why not just scale up from the beginning on? If you do not have the resources, you need a lot of money anyways to pay the upscaled rent afterwards.

I'm not sure if this answers your question but the last 2 companies I worked at (~7 years) both had very clear traffic spikes 9a-5p US east coast hours on weekdays. My current place actually sees more than 20-30% drop sunday nights compared to monday morning, and it's constantly going up because we have a lot of American enterprise customers.

Maybe I misunderstood your question but is there a case where you can keep your entire capacity running for free? I'd assume you pay AWS/other cloud or your electricity provider.

Linode has a series of practical articles on how to use autoscaling with Keda in LKS [1]. The ability to scale up/down has obvious cost saving benefits, while retaining the ability to serve peak traffic or optimize background work.

kubernetes is dying, isn't it?

Could you explain how you arrive to that conclusion from seeing some proyect offering an alternative autoscaling engine?

The only issue I have with the default HorizontalPodAutoscaler is that I cannot scale down to 0 when some processing queues are empty. Other than that, we have shrines erected to k8s.

The New York Times crossword comes out every night at 10pm. There is a traffic spike. It’s huge.

I have the opposite question: who is on the cloud and has such consistent workloads they never need to scale up or down? I'm sure those users exist but they must be the minority, right?
