And if you don't need advanced features, go with Security Groups zones,
they're the most scalable and simple (but you lose built-in features
like LB, VPN etc).

Depends. If you use XenServer/XCP or VMWare you will be limited to 64
hypervisors per cluster by the platforms.
With KVM there is no limit, but you will want to stop somewhere as all
that broadcast chatter will become noisy, among other complications.
Largest deployments anecdotally seem to be in tens/hundreds of
thousands
of hypervisors.
Biggest pro compared to most other solutions - 1-2 skilled sysadmins
can
make it work and keep it working.

Hello Cloud Stack experts!
We are considering using Cloud Stack to setup a private cloud. I was
wondering if there are any scale and performance numbers that are
published. I would like to know the following:
- How large a single cloud stack cluster can be in terms of number of
bare
metal machines? Anyone know of the largest installation?
- What is the VM placement rate? i.e. How many VMs create requests can
be
submitted and how fast does the scheduler process these requests?
- Any pros or limitations compared to other cloud softwares like
OpenStack or Kubernetes others?
Thanks,
Leo
