Reality exists for Windows/Linux servers as well. Entry level ProLiant
servers end up with server utilization of less than 20% busy.

Reality is that the server HW has advanced so much, that the traditional
one bus app to one server model is really a waste.

Heck, even many Linux/Windows VM's we have migrated in the past are not
that much busier either.

Using traditional "put the OS CD in and boot" that is true. Definitely
room for improvement.

Of course, the same is true for Windows and Linux environments as well.

Of course, for med to large environments, no one installs new OS's that
way anyway, so this is really only true for small environments.

In med to large environments, they use "gold" images (image saveset of
pre-built master image) or templates (VMware) to deploy new OS's.

In OpenVMS, you could also build master LD containers to image backup to
new OS, customize and reboot. Maybe 15-30 minutes start to finish?

Could also be part of cluster with common system disk which most other
platforms do not have (common start-ups etc.)

Apparently to be addressed in X86-64 license model.

Cloud marketing hype.

Please tell me of any Customer who absolutely needs VM or OS's within
minutes and I will tell you a Customer who is not involved with their
business and does not know didley about capacity planning.

For those 10 or less Customers in the world that really need OS's within
minutes - go to Amazon and Azure (hopefully consistent latency is not an
issue for their App)

Cloud marketing hype. What you get within minutes is "IT lite" i.e. A VM
spin-up, but without any AV, no OS patching, no monitoring integrated
with your service desk, no backups, no security hardening, no firewalls.

Yes, you can add these on (extra costs), but this where cloud providers
insert "yes, additional planning is required". Duhh..

Internal IT Depts provide full service OS instances per their company
policies. Does it take longer? Sure. But it's much more integrated and
"ready" for a prod environment.

Agree.

Lets not forget the SW costs are typically the biggest slice of the IT
stack by far - on every OS.

Small dual core server in a 2 node RAC cluster on Windows/Linux running
Oracle Server will likely cost about $200K for the Oracle licenses
alone.

Servers running at $3K-$10k are usually not that big of a factor.

Good news for Oracle on OpenVMS Integrity or Alpha Customers - their
Oracle server (AND Rdb) license costs should drop by 50% when they move
to X86-64.

This is because the Processor Multiplication Factor which Oracle uses to
stifle their competitive HW platforms is 1.0 for Integrity, Power and
Alpha, but is only 0.5 for X86-64. It makes no difference what the OS
is.

This alone will likely make a move from OpenVMS Integrity to OpenVMS
X86-64 a no brainer.

You are comparing the now to the past, not the now to the future
announced plans.

As example - new license model (subscription based?), new virtualization
capabilities, new emulators etc.

No doubt existing OpenVMS hosting and remote support providers like SCI
(and others) will jump on the HCI movement which is taking over many
large data centers. It is a way to significantly reduce the
infrastructure and associated server/storage costs typically used for
hosting very high numbers of VM's. 

Note - SAN folks will not like this as HCI uses local storage with a
hypervisor on top to server the local drives to other cluster nodes. It
is not unlike OpenVMS clustering in a box.

Some HCI companies, like Nutanix (very popular now btw), support KVM
hypervisors which would be a nice fit for the planned virtualization
features planned for OpenVMS V9+ releases.

Reference:
<www.nutanix.com>

Note - while VMware is the most popular hypervisor today, many Customers
are really complaining about the high licensing costs, so KVM solutions
could become much more popular in the future. With a small company
called Red Hat developing KVM, you can be sure KVM will only get more
popular in the future. Yes, OpenVMS and VSI can hopefully ride the wave
..

Remember my earlier point about the next 10 years being all about
reducing SW costs?
