Seems more like Cloud Run to me. A modest amount of vendor lock-in if you're only interested in running compute workloads, and the usual ton of vendor lock-in that is inherent to any effective cloud usage if you want to go all in with IBM Cloud.

It actually impresses me so far. I've got a soft spot for IBM Cloud given that its origin is creating a public cloud out of open source projects and giving back to them. Their serverless offerings so far have been lackluster though. IBM Cloud Functions, based on Apache OpenWhisk, which they created and open-sourced, has a weird programming model.

But this seems like Cloud Run except it also has support for Docker images on any registry (not just GCR) and can run batch jobs up to 2 hours long. I'm going to keep an eye on it.
