>> The final lesson for domain one.
00:00
Let's go over everything we've
00:00
learned over this whole domain.
00:00
Domain one is really about
00:00
the Cloud concepts, architecture, and design.
00:00
In this lesson, we're going to summarize
00:00
the elements we've covered over domain one.
00:00
Talk about the importance of
00:00
all those elements in domain one
00:00
and then we've got to talk about
00:00
how all these things, concepts,
00:00
risk analysis, models, services,
00:00
all of those aspects that we've covered in domain one,
00:00
how they really set up the rest
00:00
of the domains will cover in this course.
00:00
Here it is. We've seen this image a few times,
00:00
you've seen components of it,
00:00
but this really shows
00:00
most of the major concepts that
00:00
>> we covered in domain one.
00:00
>> Starting from the top, we talked about
00:00
those five characteristics of Cloud computing,
00:00
the essential elements that
00:00
really enable it to be important.
00:00
How you connect to all these resources
00:00
over the Internet,
00:00
how we're able to really pool resources
00:00
to create cost efficiency,
00:00
and how organizations can achieve economies of scale by
00:00
having other organizations manage
00:00
their Cloud infrastructure,
00:00
how they can scale things to
00:00
really pay as you go, you name it,
00:00
all of these wonderful things,
00:00
>> essential characteristics.
00:00
>> We talked about the service models,
00:00
Software-as-a-Service, Platform-as-a-Service,
00:00
Infrastructure-as-a-Service.
00:00
With each of these models, we
00:00
talked about how it can be used,
00:00
what it is, what are the components,
00:00
and then what are your security responsibilities as
00:00
the customer and what are
00:00
the Cloud providers' security responsibilities.
00:00
What are the threats
00:00
that often affect these service models?
00:00
Then we talked about
00:00
the four different deployment models and their risks.
00:00
Also, the different responsibilities,
00:00
use cases, how you justify the use of these models,
00:00
and then we really moved into
00:00
many of the important aspects of
00:00
understanding the business justification
00:00
because we can understand all of these components,
00:00
how they're used, different
00:00
aspects of the architecture,
00:00
but do design effective security is
00:00
really based on the business use case?
00:00
What are the business requirements
00:00
associated with how your
00:00
organization's going to use the Cloud?
00:00
What regulations apply to it,
00:00
and what are the most critical elements?
00:00
We figured out that those elements are
00:00
identified using the business impact analysis
00:00
and in tandem with many of
00:00
the aspects of how the Cloud is being used,
00:00
the business impact analysis,
00:00
a brain works that you're going through,
00:00
any regulations that apply to your usage of the Cloud,
00:00
those elements really drive the
00:00
>> security requirements and
00:00
>> responsibilities for how you're going to
00:00
protect the Cloud and the services within it.
00:00
Those elements really are
00:00
what domain one is about a nutshell.
00:00
Now, we have a common understanding,
00:00
the language of roles, responsibilities,
00:00
>> technical terms, and the infrastructure models
00:00
>> that we're going to go into
00:00
>> greater depth in future lessons
00:00
and modules in the course.
00:00
We've got a longer reflection
00:00
here because we've covered a lot in domain one
00:00
but these are really the
00:00
critical questions I want to think
00:00
about that we answered in domain one.
00:00
First, what is Cloud computing and its benefits?
00:00
We talked about those five essential characteristics.
00:00
What are the three service models?
00:00
Not only what are the models,
00:00
but how are they used and
00:00
what are the different security
00:00
responsibilities that come with each.
00:00
What are the four deployment models?
00:00
Then we've seen it so many times but what does
00:00
the shared responsibility model look like
00:00
for each service model and why is it important?
00:00
How does that help you understand
00:00
what your organizations are responsible
00:00
for and what the Cloud provider is doing,
00:00
and what risks are involved in that?
00:00
Then overall, how do you
00:00
demonstrate the business value of the Cloud?
00:00
How do we justify using the Cloud?
00:00
How do we realize those benefits?
00:00
Then based on what
00:00
our business is trying to accomplish in the Cloud,
00:00
how do you identify and meet
00:00
your organization's security
00:00
responsibilities in the Cloud?
00:00
Those are really some of the high-level concepts
00:00
and elements we answered in domain one,
00:00
and we're going to just
00:00
continue adding levels of granularity,
00:00
complexity, and new concepts
00:00
in the domains and lessons that follow.
00:00
In summary, we talked about
00:00
the components and benefits of Cloud computing,
00:00
we talked about those architectural concepts
00:00
of Cloud computing in domain one,
00:00
and we talked with the security considerations
00:00
for using Cloud services
00:00
We really set the table
00:00
here for so much more that
00:00
>> is going to come in domain one,
00:00
>> and I hope you feel you've learned a lot.
00:00
We have so much more to come and
00:00
>> I'm excited to continue.
00:00
>> See you in the next lesson.
