1 00:00:00,820 --> 00:00:07,640 Intersection and take a look to the clubs and the network programming Let's go and meet the club and 2 00:00:07,640 --> 00:00:15,410 then we were to shoot first class competing poort shared computer processing resources and they told 3 00:00:15,410 --> 00:00:24,290 to computers and other devices and then poor DeWyze and location independence and cost reduction. 4 00:00:24,350 --> 00:00:33,330 There are three types of cloud services and they are software as a service platform as a service and 5 00:00:33,330 --> 00:00:42,070 the infrastructure as a service software as a service is cloud computing all through the poor others 6 00:00:42,200 --> 00:00:46,860 users with access to it when there's cloud based software. 7 00:00:47,030 --> 00:00:51,840 Users do not install applications on their local devices. 8 00:00:51,840 --> 00:01:00,860 Instead the applications reside on a remote cloud network accessed through the web or an API through 9 00:01:00,860 --> 00:01:02,180 their applications. 10 00:01:02,180 --> 00:01:08,270 Users can store and analyze data and collaborate on projects. 11 00:01:08,280 --> 00:01:10,860 The examples of the software is service. 12 00:01:10,880 --> 00:01:17,640 Maybe social networks CRM programs online games are something like that. 13 00:01:18,470 --> 00:01:25,190 Platform as a service is a cloud computing poor its users with a clutter and Wymans way in which they 14 00:01:25,190 --> 00:01:33,350 can do up manage and deliver applications in addition to storage and other computing resources. 15 00:01:33,500 --> 00:01:41,990 Users are able to use a suite of pre-built tools to deal up customize and test their own applications 16 00:01:42,260 --> 00:01:48,880 and the examples are Windows Azure and Google App Engine and something like that. 17 00:01:49,190 --> 00:01:56,780 And lets go ahead with the infrastructure as a service infrastructure as a service is cloud computing 18 00:01:56,990 --> 00:02:05,690 offering in which render poor users access to computing resources such as servers storage and networking 19 00:02:06,080 --> 00:02:14,270 organizations use their own platforms and applications within their service providers infrastructure 20 00:02:14,600 --> 00:02:22,830 instead of purchasing hardware outright users pay for infrastructure as a service on demand. 21 00:02:22,970 --> 00:02:26,590 And examples are the Amazon web service. 22 00:02:26,600 --> 00:02:30,450 We Mbare open sake and something like that. 23 00:02:31,970 --> 00:02:40,310 There are three types of clouds and they are private public and the Hiebert clouds private cloud is 24 00:02:40,310 --> 00:02:46,040 a cloud infrastructure operated only for a single organization. 25 00:02:46,040 --> 00:02:53,930 Public cloud services are Rendle all over and now it is open for public use and the Hiebert cloud is 26 00:02:54,200 --> 00:03:04,450 composition of two or more cloth's may be a private or the public clouds let's go with the wind chill 27 00:03:04,450 --> 00:03:13,190 zation where choosing is act of creating a virtual version of something including virtual computer network 28 00:03:13,190 --> 00:03:21,250 hardware Perl plus firm's operating systems storage devices and computer network resources. 29 00:03:22,610 --> 00:03:31,130 Sure Rachel zation read refers to partitioning of physical so it into smaller virtual service to help 30 00:03:31,400 --> 00:03:33,950 maximize your server resources. 31 00:03:33,950 --> 00:03:43,010 In contrast the dedicating one's over to a single application or task and poor is cost reduction because 32 00:03:43,010 --> 00:03:43,950 you lose. 33 00:03:44,040 --> 00:03:49,620 Use less equipment energy space and something like that. 34 00:03:49,670 --> 00:03:55,600 Near as you can see we have just one Cowdray one shesays in here. 35 00:03:55,960 --> 00:04:04,280 But we can show as they ever in types of the services by using just the air. 36 00:04:04,400 --> 00:04:15,960 Single server Liskov the hypervisor term hyper WASER So our computer software for way or Hardaway's 37 00:04:16,080 --> 00:04:20,160 that creates ones virtual machines. 38 00:04:20,160 --> 00:04:22,300 There are two types of hypervisor. 39 00:04:22,380 --> 00:04:33,070 And they are type 1 and Type 2 Type 1 hypervisor is run directly on the hosts hardware to control the 40 00:04:33,280 --> 00:04:35,330 hardware and to manage Yes. 41 00:04:35,380 --> 00:04:45,430 Operating systems and the examples are 3000 server Microsoft Hyper-V Oracle MSO we're and Etzler up 42 00:04:46,090 --> 00:04:54,270 type 2 hypervisor strong on our commercial operating system just as other computer programs do. 43 00:04:54,310 --> 00:05:03,360 And for example when my workstation which you Merc's can move and something like that let's call it 44 00:05:03,370 --> 00:05:05,130 network programming. 45 00:05:06,730 --> 00:05:09,960 That programming is an approach to computer networking. 46 00:05:09,960 --> 00:05:18,090 That alone network administrators to manage network services through abstraction of lower level functionality 47 00:05:19,730 --> 00:05:21,390 in networking device. 48 00:05:21,410 --> 00:05:30,080 Actually we have two different paths for data and control purposes and their control and the discipline 49 00:05:30,460 --> 00:05:38,390 that typically refers to all the functions and the processes that forward packet's frames from one interface 50 00:05:38,390 --> 00:05:45,280 to another and control plane refers to all the functions and processes that that are mean. 51 00:05:45,410 --> 00:05:55,400 Which path to use for example routing protocols spanning three LDP aired the examples of the control 52 00:05:55,430 --> 00:06:03,020 plane applications we have to come on network ritual zation architectures and they are SDN which is 53 00:06:03,020 --> 00:06:09,710 commonly associated with the open full of protocol for data mining the path of network pockets and the 54 00:06:09,860 --> 00:06:14,350 Cisco s.c.i which can be used with open stack. 55 00:06:14,480 --> 00:06:23,740 Cisco ACA is Cisco's network which uses a solution enables application Eduljee and datacenter automation. 56 00:06:23,960 --> 00:06:33,700 Customers can build multi-column networks with a core system Poissy module two additional devices have 57 00:06:33,700 --> 00:06:44,020 separate control and data plan for each device as the end software defined networking combines the control 58 00:06:44,020 --> 00:06:48,780 plane of H-2 eyes to a central control. 59 00:06:50,440 --> 00:06:58,900 S10 controllers act as a strategic control point in the Estyn network like the brain of the network 60 00:06:59,170 --> 00:07:06,980 and manage flow control to the Swades others and populates the flow table entries. 61 00:07:07,080 --> 00:07:16,000 Open flow of users will ask for carrying the control plane traffic securely we have three tables for 62 00:07:16,030 --> 00:07:23,950 open flow protocol the flow table matches the incoming packet stress specific flow and specifies the 63 00:07:23,950 --> 00:07:32,140 functions that are to be performed on the pet cats mid-to table triggers a variety of performance related 64 00:07:32,170 --> 00:07:41,900 actions on a flow and group table triggers where each of actions that effect one or more flows. 65 00:07:42,180 --> 00:07:50,760 And we have three types of the SDN the wash based the SDM using the Wes's are programmed to read the 66 00:07:50,760 --> 00:07:55,080 applications on the device itself or on the server. 67 00:07:55,080 --> 00:08:05,220 For example Cisco one k controller based SDN uses central controllers for example open daylight and 68 00:08:05,260 --> 00:08:11,900 polarized based SDN controllers use a controller and plus a pool isolator. 69 00:08:11,910 --> 00:08:15,080 For example Cisco epic and.
