>> As I said earlier,
virtualization just naturally leads
itself to discussions on Cloud computing.
If we're looking at Cloud computing,
it really exists because of virtualization.
Like we said, makes it profitable is
organizations like Google, Amazon,
and Microsoft investing in
a lot of really high-end equipment,
then divvying it up and leasing it
out to individual organizations,
that's where we get Cloud computing.
Now, NIST has a definition that they give us.
Ultimately, what they're saying is
Cloud computing is a model
and listens to some of the requirements.
It's ubiquitous and available everywhere,
it's convenient and on-demand,
I can access my Cloud-based resources,
I have access to a shared pool of
configurable computing resources and that's with me.
I don't have to go through the Cloud service provider,
if I've Infrastructure as a Service and I'm
in components of the Cloud service provider,
I can spin up 100 hard drives or servers very quickly,
and then I can decommission
>> them once I don't need them,
>> which is rapid provisioning.
I can very quickly add to my network and
very quickly release those resources.
Again, because this is software-driven,
we have a lot of flexibility.
What are the drivers to move to the Cloud?
Honestly, it comes down to the fact that
senior leadership believes
the benefits outweigh the costs.
Part of this is the pay as you use benefit rather than
paying a flat fee regardless of how much I use,
I'm only going to pay for what I use in this case.
There's a lower total cost
of ownership and that's the goal.
If I'm not paying for excessive use,
then it costs less in long-run.
In some cases, it may be like leasing a car.
If I buy a car, that I have to worry
about all the maintenance and deprecation,
but if at lease the car,
then over time it winds up costing me more money.
But I do have those benefits of being
able to return the car when I'm done,
and any of those major upgrades
are often taken care of for me.
Lower total cost of ownership is the goal,
but sometimes we see that over time
we could conceivably spend more money.
If that's the case, then what we're really doing is
trading capital expenditure for operational expenses,
rather than having all that money
upfront or paying a monthly or quarterly basis.
Ideally, we get greater reliability,
scalability, and sustainability.
We're taking advantage of the resources that
these major organizations have
and the investments they've made.
It keeps me from having to purchase
my own data center and to
develop or build my own data center.
Stock or with servers,
heat it, cool it,
secure it, control access to it, and so on.
Now, everything that used to be my data center is
simply access to the Internet
at the Cloud service provider.
Ideally, because of the many
tremendous resources they have,
we get greater up time,
and ideally, we get additional security,
but that's only guaranteed based
on your service level agreement.
Many times I've heard people say they'll secure it
better than me will, but not necessarily.
Your service level agreement
with your Cloud service provider
is really going to be critical
as to what you can expect,
and a service level agreement is just commitment.
If we don't have audits or some third-party assurance
that are Cloud service provider honors their SLAs,
then we need to move on and look at
another Cloud service provider.
I'm not going to read every one of these,
but it's for automation,
easy deployment, you don't get much easier
than software-based deployment of components.
Device and location-independent often a company like
Amazon is going to have
distributed devices throughout the world.
If there's a local issue that happens,
our deal is still going to be available because it
resides in so many other locations.
24-7 support is something we
may not have in our organization,
so with your Cloud service provider,
assuming it's in the service level agreement,
we'll provide those benefits.
What most people focus on for
the Cloud is that it's going to
>> save us money over time.
>> We're not going to have to buy these servers,
we're not going to have to heat them and cool them,
which is a really expensive cost,
and we're not going to have to secure them.
We're going to be able to access
our information from anywhere on the planet,
and that's a tremendous benefit.
Cloud computing has a lot of selling points.
