I just did a comparison for a 2GB Ram / 2 core / 60GB disk VM. Aruba (vSphere) comes out 1-2% cheaper than HP (KVM). I love the "Eliminate lock-in: Stay independent through open source-based architecture and standards-based APIs" Which standards? Is there any? Massimo. Thanks for the heads up.

Take a look here http://hpcloud.com/products/cloud-compute Massimo you weren't that wrong when you said a KVM based cloud wouldn't be much cheaper. IMO HP proves that not even a giant HW manufacturer ( which can leverage his own HW infra ) using KVM is significantly cheaper than the players you already compared in your blog post.

Considering that, probably, IBM still makes more money on the AS/400 compared to how much AWS makes out of cloud I'd say 20 to 30 years is an aggressive statement. No doubt there are a lot of companies that are deep into cloud already but the like of Netflix is the exception, not the norm. Thanks for chiming in.

A diagram would be best to describe what you would like to achieve. One thing to note though is that a vCD "Network Pool" is really a collection of layer 2 networks (either created using vCDNI technology or regular VLANs) that you declare. For example when you create a VLAN-backed Network Pool you are essentially telling vCD that your vDS switch (and ESXi hosts) have specific VLANs available to use (eg 3000 to 3100). Only afterwards when you create Org Networks or vApp Networks these VLANs get used to create a PG and you define a subnet. In essence a Network Pool has nothing to do with a class of IPs.

I noticed the table missed another key metric. The businesses will go for lowest cost and most agile. The table correctly indicates that design for failure is lowest tco. I believe that devops on design for failure clouds are also the most agile. The statement that many companies will take 20 to 30 years to get there is a bit naive given the extremely fast adoption of cloud technologies. Now I'm not saying that companies will get their entire infrastructure on this type of cloud, they never will move entirely. But as companies start to realize the benefits application by application, I expect adoption will accelerate dramatically. In fact I think early adopters are already on this path. Frank,

In my lab I have vDS and 3 ESXi 5.0 HA/DRS Clusters with 2 port groups for External connectivity to the outside world and the other port group for my Local LAN, Microsoft TMG is used for proxing and firewall both outwards and inwards. My internal LAN is on a 192.168.2.0/24 network, using vCD I felt my best plan of action will be to use the PORT GROUP BACKED NETWORK POOL, when I create a Network Pool in vCD considering internally in my vsphere environment my LAN address is 192.168.2.0/24 Network, will my vCD Nework pool address reserved have to be using the same Network as my internal address or can I say create a pool from say 192.168.3.0/24 and if yes what will be the default gateway and will it be possible to have communication between both environments Massimo, thanks for your prompt reply it makes thinks clearer now, I will like to ask another question, I have read all your labs as well as vCD admin guide and vCAT 2.0 downloaded from vmware, I gave a lot of my time to the Network aspect of vCD as I believe it to be most crucial, I’m going to be setting up my private lab this weekend, here goes my question.

Both products (vCD and View) talk to vSphere but they are sort of parallel. With vCD you can indeed instantiate desktop OSes and you can configure VPN access but I doubt that vCD alone could fulfill the requirements you have. As of today View doesn’t integrate well with vCD.

vCD I know provides Infrastructire as a service, can it be used for the following:

1) Provision windows workstations for hundreds of end users for day to day work working at home or in the office
2) If users are working from home what will be the best practice way to connect i.e via VPN etc
3) Can vmware view work along side vCD for Desktop virtualisation
