Can anybody give me a list of the components needed to start a private cloud?
I've read tons of articles on cloud computing but theirs not a single one that just gives you a list what you will need!

The main components are:

- Hypervisor Server
- Controller Server
- Storage Device

You can build a cloud a scalable cloud with 1 Hypervisor node.

What Hypervisor did you want to offer?

How can you build a cloud with 1 hypervisor? Thats just a VPS node. You'd need 2-3 to start with, along with a management server. Where will the cloud instance cold migrate to in event of hardware failure? I do agree it will still be scalable.

You will need storage, this can be in a SAN or more reliably Onapp now offers onboard storage utilizing the hard drives in hypervisors themselves. Reason it's more reliable, SAN goes down/breaks/dies, your cloud is down! SSD's or high performance SAS is recommended for storage.

You will then need a few higher end switches, to plug in network and storage. You will need stacking modules to stack these together. And you will need a lot of network cabling.

It can be pretty complicated as it is not just plug and play like the way you plug a normal server into a switch, there is a fair bit or network/storage engineering required. You are better off just "hiring" a private cloud infrastructure service, unless you do want to fork about £10k or so on hardware/switches and a rack.

For software you really have a choice between OnApp or Openstack, a lot of larger providers opt for OnApp as it's supported by OnApp/UK2, so it has business/corporate support. I believe RHEL actually offers support packages for openstack as well, however.

Here's what OnApp suggest: http://onapp.com/cloud/requirements/ http://onapp.com/storage/
