I'm not much into hosting jargon, but VPS if i'm not mistaken, means
jailed linux env, i.e. lxc, docker container or chroot'ed environment
that appears like a dedicated virtual server but shares resources and
common drivers with its host.
Dedicated virtual server implies fully virtualized server - where
everything down to the bios is emulated.
The "Cloud" is just a hype word marketing folks would like to apply, it
has way too many meanings and unrealistic expectations - depends who you
ask - to each, his own.

Hi everyone,
I'd like to set up a new cloud cluster using CS platform. I do have a few
questions though if you don't mind.
1. Marketing "cloud hosting", "cloud vps" or "cloud dedicated servers"
is essentially the same thing correct, except the typical CPU/disk
allowance? Is that correct?
2. Is there such a general difference between a cloud vps or cloud
dedicated here? My understanding is, there isn't but want clarification. For
example, if I have a few old rackmount servers, can I throw this into the
cloud cluster? If so, how is it that the cloud would use CPU/RAM from one
box and the customer data on a separate storage box? This confuses me.
For initial hardware, I have the following in mind. Please tell me if this
looks reasonable to offer cloud hosting, cloud vps. I'm going off the
small-scale deployment sample
If I understand correctly, there are generally 3 boxes (aside core
router/switches)
1. Management console that has CS installed
2. Storage server
3. CPU/RAM server
Is this correct? I won't be using VMWARE either but would like to offer
typical shared hosting with cPanel, reseller hosting with cPanel/WHM, VPS
options (Xen, KVM, OpenVZ) and dedicated servers if viable with CS.
My initial intended deployment:
CS Management Server
- Quad Core Xeon, 8GB RAM, RAID SSD drives for redundancy (approx.
128GB)
- Centos 7 64bit (if this isn't supported yet, 6.5v)
Storage Server
- Document says NFS, but is FreeNAS storage server ok?
- 2x Quad Core Xeon, 16GB RAM, RAID 10 drives (preferably 5 + 5 or
maybe just 2 + 2 to start)
- should a storage server require SSD for optimal performance or is
this overkill?
Computing Nodes
- I assume this is where all the CPU/Memory comes from? If so,
- 32GB RAM
- 2x Hexacore Xeons w/ Turbo
- anything else?
Sorry for the long list. Just want to make sure I have a full understanding
before tackling this setup. Thanks.
