>> In the previous section,
00:00
we talked about the various services that
00:00
we might want from our Cloud service provider.
00:00
The next thing we have to think about is
00:00
how do we want our deployment to work?
00:00
When I say the deployment,
00:00
we've got various deployment models that are public,
00:00
private, hybrid, and community.
00:00
What this deals with is who's going to
00:00
share the hardware where your data is stored?
00:00
Of course, the cheapest is going to be the public.
00:00
We're going to use Amazon's web services or whomever,
00:00
and these services are publicly available.
00:00
This is where we have multi-tenancy though.
00:00
What this means is my data,
00:00
my resources, my servers,
00:00
everything is going to be running in
00:00
a virtualized environment on
00:00
a server that might have 10 other customers.
00:00
Those 10 other customers,
00:00
I don't have any information on.
00:00
I don't have any say on the actual security of
00:00
that server. That might be a concern.
00:00
This is not for top-secret information.
00:00
However, many organizations choose
00:00
this option because it is the cheapest.
00:00
In a private cloud however,
00:00
you get a little bit more control because you're
00:00
the only organization that is
00:00
accessing the services exclusively.
00:00
There is no co-mingling of data.
00:00
There is no multi-tenancy.
00:00
Essentially, what you have is you have
00:00
resources that are available to you,
00:00
but their access across the Internet,
00:00
and usually they're maintained
00:00
by a Cloud service provider.
00:00
We in our organization can
00:00
maintain a private cloud as well.
00:00
For instance, the government's Cloud services provider
00:00
or the government's Cloud is going to be managed
00:00
>> by the Department of Defense and those entities
00:00
>> because of the greater need for security.
00:00
>> If I'm an organization that's storing
00:00
personally identifiable information
00:00
>> or personal and financial information,
00:00
>> probably the private cloud is going to be best for me.
00:00
Something in the middle is called the Community Cloud.
00:00
A community Cloud service provider
00:00
>> will be specializing towards a specific industry.
00:00
>> Usually that industry is going to have set
00:00
security configurations and requirements.
00:00
Let's say I'm a health care provider
00:00
and I collect information on
00:00
my patients that's considered to be both PII and PHI,
00:00
personally identifiable information,
00:00
personal healthcare information.
00:00
Both of those need to be protected.
00:00
I might want the cost of a public cloud
00:00
>> because it's cheap.
00:00
>> But the privacy of a private cloud,
00:00
I'm going to look for something in the middle.
00:00
A community Cloud service provider is
00:00
going to provide services in this instance
00:00
>> to other health care providers
00:00
>> and to give the assurance of meaning, the regulations,
00:00
>> and the requirements with HIPAA.
00:00
>> I don't have exclusive use.
00:00
There's still multi-tenancy,
00:00
but I do have a higher degree of security,
00:00
which I'm going to need for my environment.
00:00
Then we also have a hybrid.
00:00
Hybrid is one of those situations
00:00
where I have private cloud access.
00:00
But from time to time,
00:00
like with burst businesses,
00:00
I may need to access resources from the public cloud.
00:00
I have the primary privacy of
00:00
a private cloud most of the time,
00:00
but when there's an increase in demand like
00:00
the Christmas holidays for instance,
00:00
then I may borrow resources.
00:00
Sometimes it's called Cloud bursting.
00:00
We get that in a hybrid environment.
00:00
Wrapping up the Cloud.
00:00
The big things to understand about
00:00
Cloud computing first of all,
00:00
know what Cloud computing is and why we care.
00:00
Our driver, saving money,
00:00
ubiquitous [inaudible],
00:00
strong network availability, and resources.
00:00
Then with our Cloud services,
00:00
we have software as a service,
00:00
we have platform as a service,
00:00
we have infrastructure as a service.
00:00
We have shared responsibility
00:00
>> across the service models.
00:00
>> It's always good to understand
00:00
>> how we trade off flexibility
00:00
>> for configuration options and control.
00:00
>> Last, we looked at Cloud deployment models,
00:00
which are going to consist of public or private cloud.
00:00
Then we set community Cloud right in the middle.
00:00
Then hybrid takes private cloud.
00:00
Then for burst, we use resources from the public cloud.
