Intersection and take a look to the clubs and the network programming Let's go and meet the club and
then we were to shoot first class competing poort shared computer processing resources and they told
to computers and other devices and then poor DeWyze and location independence and cost reduction.
There are three types of cloud services and they are software as a service platform as a service and
the infrastructure as a service software as a service is cloud computing all through the poor others
users with access to it when there's cloud based software.
Users do not install applications on their local devices.
Instead the applications reside on a remote cloud network accessed through the web or an API through
their applications.
Users can store and analyze data and collaborate on projects.
The examples of the software is service.
Maybe social networks CRM programs online games are something like that.
Platform as a service is a cloud computing poor its users with a clutter and Wymans way in which they
can do up manage and deliver applications in addition to storage and other computing resources.
Users are able to use a suite of pre-built tools to deal up customize and test their own applications
and the examples are Windows Azure and Google App Engine and something like that.
And lets go ahead with the infrastructure as a service infrastructure as a service is cloud computing
offering in which render poor users access to computing resources such as servers storage and networking
organizations use their own platforms and applications within their service providers infrastructure
instead of purchasing hardware outright users pay for infrastructure as a service on demand.
And examples are the Amazon web service.
We Mbare open sake and something like that.
There are three types of clouds and they are private public and the Hiebert clouds private cloud is
a cloud infrastructure operated only for a single organization.
Public cloud services are Rendle all over and now it is open for public use and the Hiebert cloud is
composition of two or more cloth's may be a private or the public clouds let's go with the wind chill
zation where choosing is act of creating a virtual version of something including virtual computer network
hardware Perl plus firm's operating systems storage devices and computer network resources.
Sure Rachel zation read refers to partitioning of physical so it into smaller virtual service to help
maximize your server resources.
In contrast the dedicating one's over to a single application or task and poor is cost reduction because
you lose.
Use less equipment energy space and something like that.
Near as you can see we have just one Cowdray one shesays in here.
But we can show as they ever in types of the services by using just the air.
Single server Liskov the hypervisor term hyper WASER So our computer software for way or Hardaway's
that creates ones virtual machines.
There are two types of hypervisor.
And they are type 1 and Type 2 Type 1 hypervisor is run directly on the hosts hardware to control the
hardware and to manage Yes.
Operating systems and the examples are 3000 server Microsoft Hyper-V Oracle MSO we're and Etzler up
type 2 hypervisor strong on our commercial operating system just as other computer programs do.
And for example when my workstation which you Merc's can move and something like that let's call it
network programming.
That programming is an approach to computer networking.
That alone network administrators to manage network services through abstraction of lower level functionality
in networking device.
Actually we have two different paths for data and control purposes and their control and the discipline
that typically refers to all the functions and the processes that forward packet's frames from one interface
to another and control plane refers to all the functions and processes that that are mean.
Which path to use for example routing protocols spanning three LDP aired the examples of the control
plane applications we have to come on network ritual zation architectures and they are SDN which is
commonly associated with the open full of protocol for data mining the path of network pockets and the
Cisco s.c.i which can be used with open stack.
Cisco ACA is Cisco's network which uses a solution enables application Eduljee and datacenter automation.
Customers can build multi-column networks with a core system Poissy module two additional devices have
separate control and data plan for each device as the end software defined networking combines the control
plane of H-2 eyes to a central control.
S10 controllers act as a strategic control point in the Estyn network like the brain of the network
and manage flow control to the Swades others and populates the flow table entries.
Open flow of users will ask for carrying the control plane traffic securely we have three tables for
open flow protocol the flow table matches the incoming packet stress specific flow and specifies the
functions that are to be performed on the pet cats mid-to table triggers a variety of performance related
actions on a flow and group table triggers where each of actions that effect one or more flows.
And we have three types of the SDN the wash based the SDM using the Wes's are programmed to read the
applications on the device itself or on the server.
For example Cisco one k controller based SDN uses central controllers for example open daylight and
polarized based SDN controllers use a controller and plus a pool isolator.
For example Cisco epic and.
