For the purposes of "Microsoft Azure cloud concepts" in the Az-900 exam, would a "traditional" datacenter operation with some public facing service count as a private cloud?
By traditional datacenter:
- On-premise server room
- Inside said server room is a rack containing web servers with a hardware load balancer
- You're not scalable because you literally need to rack a new server to scale out
- You are doing plain old VLANs with switches and routers (so no intent based networking, VMWare VXLAN, etc)
- Again you have no elasticity because someone has to at least dive into command line or scripts manually, or run cable to create a new network segment
Personally, I think it that setup is not private cloud because you have a bunch of hardware and software with an Internet-facing presence, but you lack Elasticity and Agility from the "Explore key cloud concepts".
Looking at Microsoft's own "Define private cloud", it is ambiguous or at least unclear:
Oddly a traditional datacenter meets everything discussed in that page except for the fact that it can't really be called "cloud" since it lacks a lot of the advantage.
So for the exam, do they consider any 100% on-premise compute service a "private cloud", or does a private cloud need to cover a certain amount of "cloud computing" properties before you call it a private cloud?
(I'm thinking there must be some threshold you need to cross, or else you could naively say that a single physical web server and physical router/firewall directly attached to a modem in the office is a private cloud ;) )
