>> Having gone over what we're going to cover domain
00:00
one in Module 1.2,
00:00
we're going to go over what is
00:00
cloud computing and what are its key characteristics?
00:00
The learning objectives for this module are to
00:00
identify the five characteristics of cloud computing,
00:00
explain how each characteristic
00:00
>> enables cloud computing,
00:00
>> and describe how the characteristics work in
00:00
concert to enable cloud computing.
00:00
[NOISE] The National Institute of Standards
00:00
and Technology defines cloud computing as well,
00:00
"Cloud computing is a model
00:00
for enabling ubiquitous, convenient,
00:00
on-demand network access to
00:00
a shared pool of configurable computing resources,
00:00
e.g, networks,
00:00
servers, storage, applications,
00:00
and services that can be
00:00
rapidly provisioned and released with
00:00
minimal management effort
00:00
or service provider interaction."
00:00
Wow, that's a mouthful.
00:00
Let's talk about how
00:00
these five characteristics really
00:00
bring cloud computing together.
00:00
The first characteristic is broad network access.
00:00
Basically, without being able to
00:00
access and share data over the Internet,
00:00
there would be no cloud computing.
00:00
Without a connection to the Internet
00:00
and remotely hosted resources,
00:00
cloud computing would not be possible.
00:00
Second, on-demand self-service; what do you need?
00:00
You can immediately get it yourself.
00:00
Well, you don't have to wait for anyone
00:00
else to spin up the services you need in
00:00
the cloud and that's one of
00:00
the major benefits of cloud computing.
00:00
Resource pooling: This is the ability to use
00:00
the same hardware to help
00:00
multiple Cloud customers at one go.
00:00
Metered services; basically,
00:00
you only pay for what you use.
00:00
Your Cloud provider will keep track
00:00
of how much computing services you're
00:00
using or how many servers you are spinning
00:00
up in the Cloud and you'll only
00:00
pay for what do you really need.
00:00
Then the final characteristic is rapid elasticity.
00:00
Basically, if there's greater demands on
00:00
your application or you
00:00
need to spin up more development environments,
00:00
you can rapidly do that using cloud computing.
00:00
Now, this diagram shows more
00:00
succinctly how these five elements work together.
00:00
As you can see, the larger bar at the bottom,
00:00
resource pooling really conveys
00:00
why that's an important characteristic.
00:00
All of these other aspects of
00:00
cloud computing really work well in concert because
00:00
resources are shared amongst
00:00
different customers coming in and utilizing the Cloud.
00:00
These shared resources really make
00:00
it cost-effective for everyone to
00:00
use the Cloud as a useful case for them.
00:00
Quick question, what are
00:00
the five characters of cloud computing?
00:00
One, broad network access, on-demand self-service,
00:00
resource pooling, rapid elasticity,
00:00
measured threat services.
00:00
Two, broad network assets, on-demand self-service,
00:00
resource pooling, rapid elasticity,
00:00
measured/metered services.
00:00
Finally, broad network access, on-demand self-service,
00:00
resource separation, rapid escalation,
00:00
or measured and metered services.
00:00
The answer? B; broad network access,
00:00
on-demand self-service, resource pooling,
00:00
rapid elasticity, measured/metered services.
00:00
Those are the five characteristics of cloud computing.
00:00
In this video, we've
00:00
covered the five characters of cloud computing,
00:00
which again are broad network access;
00:00
being able to access servers
00:00
remotely through the Internet, on-demand self-service;
00:00
you can access and start provisioning
00:00
things as soon as you want to; resource pooling;
00:00
the cost-benefit comes from
00:00
utilizing shared computing resources
00:00
across many customers, rapid elasticity;
00:00
you can spin up environments or
00:00
break them down as
00:00
fast as you really want to or need to;
00:00
measure meter services;
00:00
you only pay for what you use.
00:00
We covered how these characteristics enable
00:00
cloud computing and also the benefits
00:00
of cloud computing based on some of
00:00
these characteristics. See you in the next module.
