Is Network as a Service completely customizable?

Hello,

I am trying to learn about all the XaaS cloud-related models. Recently I found out there is such thing called NaaS. Unfortunately, probably due to my English skills, I can't extract particular information I would like to know about NaaS. I read Wiki article here but it didn't help me enough. So if it's not an issue, I kindly ask if you could answer directly my few questions below.

  1. Does NaaS allow user to instantiate complete, 'stand-alone', custom topology network, consisting of hosts (VMs), routers/switches along with circuits connecting them?
  2. Is there topology size limit other than the substrate capabilities?
  3. Down to what layer is NaaS customizable for the user?
  4. Is he free to choose any of possible protocols on L3, on L2?
  5. Is he able to utilize VLANs?
  6. Can the link bandwidth be set precisely or is it best effort service?
  7. What are the limitations of NaaS?

I will be glad to get any support from you.

Regards.
