* Will this at (least the scheduler / scaler component) be open source? * Any plans to scale the EC2 instances as well (scaling containers is great, but I usually need to scale out more CPU and memory as well)?
I definitely agree that there is a place for auto scaling both VMs and containers. Auto scaling with VMs means if it takes several minutes to add a VM to the cluster you have to scale up early and scale down slowly. We think auto scaling with containers can help a lot here by smoothing out the demand. Lower priority containers can be stopped while extra VM capacity is added.
