>> As I said earlier,
00:00
virtualization just naturally leads
00:00
itself to discussions on Cloud computing.
00:00
If we're looking at Cloud computing,
00:00
it really exists because of virtualization.
00:00
Like we said, makes it profitable is
00:00
organizations like Google, Amazon,
00:00
and Microsoft investing in
00:00
a lot of really high-end equipment,
00:00
then divvying it up and leasing it
00:00
out to individual organizations,
00:00
that's where we get Cloud computing.
00:00
Now, NIST has a definition that they give us.
00:00
Ultimately, what they're saying is
00:00
Cloud computing is a model
00:00
and listens to some of the requirements.
00:00
It's ubiquitous and available everywhere,
00:00
it's convenient and on-demand,
00:00
I can access my Cloud-based resources,
00:00
I have access to a shared pool of
00:00
configurable computing resources and that's with me.
00:00
I don't have to go through the Cloud service provider,
00:00
if I've Infrastructure as a Service and I'm
00:00
in components of the Cloud service provider,
00:00
I can spin up 100 hard drives or servers very quickly,
00:00
and then I can decommission
00:00
>> them once I don't need them,
00:00
>> which is rapid provisioning.
00:00
I can very quickly add to my network and
00:00
very quickly release those resources.
00:00
Again, because this is software-driven,
00:00
we have a lot of flexibility.
00:00
What are the drivers to move to the Cloud?
00:00
Honestly, it comes down to the fact that
00:00
senior leadership believes
00:00
the benefits outweigh the costs.
00:00
Part of this is the pay as you use benefit rather than
00:00
paying a flat fee regardless of how much I use,
00:00
I'm only going to pay for what I use in this case.
00:00
There's a lower total cost
00:00
of ownership and that's the goal.
00:00
If I'm not paying for excessive use,
00:00
then it costs less in long-run.
00:00
In some cases, it may be like leasing a car.
00:00
If I buy a car, that I have to worry
00:00
about all the maintenance and deprecation,
00:00
but if at lease the car,
00:00
then over time it winds up costing me more money.
00:00
But I do have those benefits of being
00:00
able to return the car when I'm done,
00:00
and any of those major upgrades
00:00
are often taken care of for me.
00:00
Lower total cost of ownership is the goal,
00:00
but sometimes we see that over time
00:00
we could conceivably spend more money.
00:00
If that's the case, then what we're really doing is
00:00
trading capital expenditure for operational expenses,
00:00
rather than having all that money
00:00
upfront or paying a monthly or quarterly basis.
00:00
Ideally, we get greater reliability,
00:00
scalability, and sustainability.
00:00
We're taking advantage of the resources that
00:00
these major organizations have
00:00
and the investments they've made.
00:00
It keeps me from having to purchase
00:00
my own data center and to
00:00
develop or build my own data center.
00:00
Stock or with servers,
00:00
heat it, cool it,
00:00
secure it, control access to it, and so on.
00:00
Now, everything that used to be my data center is
00:00
simply access to the Internet
00:00
at the Cloud service provider.
00:00
Ideally, because of the many
00:00
tremendous resources they have,
00:00
we get greater up time,
00:00
and ideally, we get additional security,
00:00
but that's only guaranteed based
00:00
on your service level agreement.
00:00
Many times I've heard people say they'll secure it
00:00
better than me will, but not necessarily.
00:00
Your service level agreement
00:00
with your Cloud service provider
00:00
is really going to be critical
00:00
as to what you can expect,
00:00
and a service level agreement is just commitment.
00:00
If we don't have audits or some third-party assurance
00:00
that are Cloud service provider honors their SLAs,
00:00
then we need to move on and look at
00:00
another Cloud service provider.
00:00
I'm not going to read every one of these,
00:00
but it's for automation,
00:00
easy deployment, you don't get much easier
00:00
than software-based deployment of components.
00:00
Device and location-independent often a company like
00:00
Amazon is going to have
00:00
distributed devices throughout the world.
00:00
If there's a local issue that happens,
00:00
our deal is still going to be available because it
00:00
resides in so many other locations.
00:00
24-7 support is something we
00:00
may not have in our organization,
00:00
so with your Cloud service provider,
00:00
assuming it's in the service level agreement,
00:00
we'll provide those benefits.
00:00
What most people focus on for
00:00
the Cloud is that it's going to
00:00
>> save us money over time.
00:00
>> We're not going to have to buy these servers,
00:00
we're not going to have to heat them and cool them,
00:00
which is a really expensive cost,
00:00
and we're not going to have to secure them.
00:00
We're going to be able to access
00:00
our information from anywhere on the planet,
00:00
and that's a tremendous benefit.
00:00
Cloud computing has a lot of selling points.
