How can we improve Compute Engine?

VM online resize of CPU/Memory

KVM supports online resize of CPU/memory, but GCE only supports offline resizing.

Online resizing of number of CPUs and memory would be very helpful to be able to handle (rare or frequently recurring) spikes for relational database workloads, where a couple of minutes of downtime to resize would not be an option.
Autoscaling based on system load would of course be a bonus, but is not initially required, as it is easily to script this in any case.

That a VM would have to be live migrated to scale up is completely acceptable IMO.

    Paul's comment seems to be a bit old. Are there any updates on this suggestion?

    This isn't supported by any cloud provider that I know of. But still, it would be a really useful feature!
