Hello and welcome back to the Salisbury 2019 carp. T A Security plus certification preparation course.
We're going continue our discussion of Marginal my three and the topic of discussion Domain three. Architectural design
Surprising enough. This is a continuation from the previous video. And what we since you're gonna do continue to summarize cloud and virtualization concepts
as mentioned, This is a continuation from the previous video
in this particular video, what we're gonna do is take a look at some important concepts as they pertain to 3.7, where we have to summarize cloud and virtualization concepts. With that being said, let's begin by taking a look at the various cloud department morals
such as the software and service
platform as a service
infrastructure as a service,
hybrid and lastly community,
one of the first cloud deployment miles won't take a look. It's called software as a service, and I saw where the service is a method for the liver and software applications over the Internet, on the man and typically on a subscription type basis.
Then we have platform as a service, was the first to cloud computer services that supplies and on the man environment for developing
testing. Delivering in managing your software applications
infrastructure as a service is the most basic category of cloud computing services
where if a sculptures service, you rent I T infrastructure or servers and Virtue machines storage
networks operating system from a calm provider on a pay as you go type basis.
Therefore, is the service models acting If a sculpture provides services one of things that we look as elasticity
now when you think about elasticity, essentially, that means the ability to basic to rapidly expand services
in terms up. For example, you want to pay for what you actually need,
and then we have a pay per use. Is another
advantage off Service D various service models.
Then we have to look at some additional deployment models, such as your private
public hybrid and well as your community.
So the private cloud refers to a cloud computing resource used exclusively by single business or organization.
Public cars are owned and operated by third party service provider. It delivers. Their computing resource is like services. Storage over the intimate
Microsoft edger is example off a public cloud.
Then we have a hybrid cloud, a hybrid clock reminds one of MAWR private clouds with one arm or public cows, for example. And organization might have their own private cloud built in their environment and also use some VM base in a service provider data center
and a somewhere the service solution in the public cloud.
Then we come to Community Cloud, which is a collaborative effort in which infra sculptures shared between a several organizations from a specific community with common concerns of the security compliance jurisdiction with a match internally or about 1/3 party and hosted internally or externally.
This brings us to some new objectives, which encompasses this 3.7 with summarize cloud and virtualization concepts.
We'll take a look at on premise versus holes
virtual desktop infrastructure, as was virtual desktop environment
plough excess security Broker
security as a service.
So we think about on premise versus hosted or versus clout
on premise. Referred to your own server room, data center or office hosted refers to 1/3 party data centers that provide segment of space for customers, computing equipment, for example. You can rent Iraq to house your service. A cloud is like a hosted environment, but instead of rent in Iraq. To put your physical server,
you purchase virtualization solutions
such as database service or infrastructure as a service environment.
The big stiff between these two system is how they deplored
Cloud based software is hosted on the Vendors server and accessed through a Web browser
on premise our way. It's still locally on the continents, own computers and servers.
So again, on premise of this stored locally on your company's own computers and service.
Klompus Software's hosted on the Venice Servant access to a Web browser.
Then we come to a virtual desktop infrastructure.
It's a virtual Jason technology. Their hosts a desktop operating system on a centralized server in a data center.
Your virtual desktop infrastructure is a veneration off on
client server computing model. Sometime referred to is your server based computing.
A excess security broker is a security solution that typically is placed between your on premise, environment and your cloud providers environment,
a car excess security broker and forces your owners of security policies in riel time.
This brings us to security as a service. Security as a service is a business model in which a service, Nevada integrates the security services into a corporate infrastructure on a subscription basis, more cost effective, and most individuals or corporations can provide on their own
when the total cost of ownership
At this point in time, we have a post assessment quiz, and it reads as follows.
Three different companies want to develop an application where they were share the cost of development resource is and future running costs,
which Cloud Morrow best describes. This is a public cloud.
Be software as a service. See ah, private Cloud
de platform as a service
e infrastructure as a service, always a F community cloud.
In this case, if you chose elf before community clout, you're absolutely correct because of communiqu allowed involves continents from the same industry that developing their own cloud that they can then share Resource is on
at this point out. Let's take a look at the key takeaways from this particular presentation and the order in which they were presented.
Doing this particular presentation, we learned that software the service is a method for deliverance software applications over the Internet on the man, typically on a subscription basis,
we learned that the platform of the service referred to a software computer service that supplies and on the man environment for developing.
Testing. Delivering Imagine your software applications.
We learned that the most basic category cloud computing services with infrastructure as a service, you read your I T infrastructure, your service and birch machines. Storage networks operating system from a cloud provider on a pay as you go basis
related. A private cloud refers to a cloud computing resource used especially by a single business organization.
We learned it a hybrid. Clark combines one of more private clouds with one arm or public clouds.
Some additional key takeaways. We learned that the on premise software is installed locally on the continents, own computers and service.
We learned it, a cloud based software hosted on the vendor server and accessed through a Web browser
in our upcoming presentation will be taken. Look at a brand new objective, which is 3.8, where we have to explain how resiliency and automation scratchy reduce risk. And again, I look forward to seeing you in a very next video
