operating, systems
(Virtualization) running a server environment like this can be _________. Not only do you have to pay for the ______ ________, but you have to pay for the floor space, the management, and the maintenance of the equipment.
expensive, server, hardware
(Virtualization) Virtualization is basically consolidating all of these physical servers with their different operating systems and applications and running them on just ___ ________ ______ in a virtual environment.
one, physical, server
(Virtualization) so in virtualization, this ___ ______ is running all of the different applications like databases, web services, and email, all running side by side on one machine. And not only the applications, but also the different _________ _______ side by side.
one, server, operating, systems
(Virtualization) So users that interact with a virtual server would interact the same way as if they were still on ________ ________ _______. They won’t be able to tell the difference.
multiple, physical, servers
(Virtual Switch) virtualization saves money. Not only does it save money on hardware, but also on _______ _____, ___________, and __________.
storage, space, maintenance, management
(Virtual Switch) In addition to virtual servers, there are other virtual devices such as virtual ________.
switches
(Virtual Switch) A virtual switch is not a physical switch, but it’s a software switch that’s created in a _______ ___________.
virtual, environment
(Virtual Switch) So for example, if you wanted your virtual database server to be able to network and communicate to your virtual web server, you can just add a _______ switch to do that. And once the ______ is added, then those two virtual servers can now ___________ with each other.
virtual, switch, communicate
(Virtual Router) a virtual router performs just like a ________ ______.
physical, router
(Virtual Router) It can route data packets between your _______ _______ and the ________ according to what the business needs are.
virtual, servers, internet
(Virtual Router) there’s a virtual firewall, which is another virtual device that can filter _______ _______ and monitor that traffic for your virtual servers, just like a physical firewall does.
network, traffic
(Cloud computing) the term cloud computing refers to data and applications being stored and run on ______ _______ rather than being on your _____ ________.
remote, servers, local, computer
(Cloud computing) this data and any applications that are on these remote servers are accessed and run via the ________. So the workload is no longer on your local computer; it’s on the _____.
internet, cloud
(Cloud computing) But email is just one example of _____ _________. There are also other services such as productivity software, web servers, databases, and so on.
cloud, computing
(Cloud computing) Now, there are three different types of cloud computing (?)
- These three vary in control and flexibility, so it’s up to the user to decide what suits their needs.
- Infrastructure as a Service
- Platform as a Service
- Software as a Service
(IaaS) The first one is ______________ ___ __ _______ (IaaS), and this type is basically when you’re going to let the third-party vendor manage a portion of your business, which is going to be the hardware portion.
Infrastructure, as, a, Service
(IaaS) The third-party vendor will manage the servers, storage, virtualization, and the networking portion. You, on the other hand, will still have control over the ________ _______, such as the applications, data, operating system, middleware, and runtime. A good example of this would be a web service company like ______ ___ ________.
software, portion, amazon, web, services
(PaaS) PaaS allows the third party to manage a portion of your business, but the third party has ____ _______.
more, control
(PaaS) In a PaaS, the third-party vendor not only manages the ________, such as servers, storage, and networking, but they also manage the _________ ______, middleware, and runtime.
You are only responsible for the ___________ and the data.
hardware, operating, system, applications
(PaaS) A good example of PaaS would be _________ _____, which is a cloud computing platform from Microsoft.
Microsoft, Azure
(SaaS) ________ ___
__ _______ (SaaS), and this type is probably the most common cloud service so far.
Software, as, a, service
(SaaS) All the applications are hosted by a _____-_____ ______ on the internet.
