In this section of the course,
we're going to discuss the cloud and the data center.
So it's now time for us to put our heads in the cloud.
Well, not really.
What I mean to say is that in this section of the course,
we're going to be discovering cloud computing,
virtualization, and the data center.
So in this section, we're going to be focused solely
on domain 1 networking concepts,
but we'll be covering two different objectives.
Objective 1.3 states,
you must be able to summarize cloud concepts
and connectivity options.
We'll also cover objective 1.8,
which states that you must be able to summarize
evolving use cases for modern network environments.
Now first, we're going to be looking at a general overview
of cloud computing, including what it is
and what it's used for.
Then we'll discuss the different cloud service models,
including infrastructure as a service,
platform as a service, and software as a service.
Next, we'll be learning all about the different types
of cloud deployment models, including public clouds,
private clouds, community clouds, and hybrid clouds.
After that, I'm going to show you
how you can begin to use the cloud yourself
by installing a simple service like Amazon light sale,
in order to create your own virtual Linux server
in the cloud, and you can use it while you're studying
for your certifications now or in the future.
Then we're going to be covering cloud connectivity
by discussing how you can reach
into the cloud-based services to configure them,
work with them and manage them over time.
Next, we're going to look at cloud security,
including how you can use virtual private clouds
to better protect your sensitive data
within the cloud provider's environment.
After that, we're going to explore network virtualization
and how common network devices like switches, routers,
and firewalls have become simply another application
that you can install and use
when you're operating inside the cloud.
Then we'll discuss SDNs or Software Defined Networks
and how they're used to separate out the three planes
used in networks and abstract them
from the underlying devices
that are actually performing those functions
in order to provide us with a more scalable
and more efficient way of operating our networks at scale.
Next, we're going to cover Software Defined Wide Area Networks
or SD-WANs and how they're used
within our cloud-based environments.
After that, we'll take a look at VXLAN,
which is known as the Virtual Extensible Local Area Network,
and this is essentially a new and improved version
of a virtual local area network,
and it's a concept that's heavily used
in our highly scalable cloud-based networks.
Then we're going to be discussing SASE and SSE,
which are the Secure Access Secure Edge,
and then Security Service Edge.
Both of these concepts are going to be used heavily
in our cloud-based networks all the time.
So it's important that we spend a little bit of time here
covering both of these related concepts.
Finally, we're going to take a short quiz
to see what you learned during this section of the course
and review your answers to make sure
you know why the right answers were right
and the wrong answers were wrong.
So if you're ready, let's get started with our coverage
of the cloud and the data center
in this section of the course.
