1 00:00:00,480 --> 00:00:05,190 In this section we will talk about why we need network automation 2 00:00:08,740 --> 00:00:12,880 even as underlying technologies have evolved guys. 3 00:00:12,880 --> 00:00:18,580 Network Management has remained largely same for decades. 4 00:00:18,580 --> 00:00:29,320 Networks are typically built operated and maintained manually network operators look into routers switches 5 00:00:29,350 --> 00:00:37,720 load balancers and firewalls and they change the configurations by day or hand and then they logged 6 00:00:37,720 --> 00:00:38,710 out. 7 00:00:38,710 --> 00:00:47,110 These procedures are largely directed at implementing and maintaining the network policies defined by 8 00:00:47,650 --> 00:00:58,450 business processes at least 70 percent of Gartner clients still use manual CLIA based chains as the 9 00:00:58,480 --> 00:01:02,050 primary mechanism for network configurations 10 00:01:04,650 --> 00:01:12,780 so when it comes to the network program ability guys this is a really technology that's really changing 11 00:01:12,780 --> 00:01:16,500 the landscape of network administration. 12 00:01:16,500 --> 00:01:25,050 It is going to change how and network administrator does day to day jobs and that is SD in which which 13 00:01:25,050 --> 00:01:29,330 is known as Software Defined Networking. 14 00:01:29,340 --> 00:01:40,200 The idea is in here instead of going individual devices such as routers switches and firewalls and configuring 15 00:01:40,200 --> 00:01:48,960 them individually we can express our intent to a network controller and that's network controller could 16 00:01:48,960 --> 00:01:58,620 simultaneously go out and configure multiple devices which gives us a great scalability to be able to 17 00:01:58,620 --> 00:02:03,870 do that and we are going to see how it works in this section. 18 00:02:03,870 --> 00:02:12,920 How do we express our intent to a controller but it can be through a program that we write or maybe 19 00:02:12,960 --> 00:02:22,550 a program written by a third party or maybe a python program or maybe a program that is accessible through 20 00:02:22,560 --> 00:02:26,400 G Y interface built into our controller 21 00:02:29,050 --> 00:02:37,630 so we we told that future going to be the network automation and add traditional manual approaches to 22 00:02:37,630 --> 00:02:46,450 the network configuration and updates are too slow and error prone to effectively support the needs 23 00:02:46,480 --> 00:02:51,990 of rapidly shifting application and data transfer requirements. 24 00:02:52,060 --> 00:03:03,420 These hands on processes make it difficult to provide the high level of service users expect and deliver 25 00:03:03,430 --> 00:03:12,820 resources to applications and I.T. operations teams on demand and implement change control and configuration 26 00:03:12,820 --> 00:03:22,870 processes and understand and manage inventory effectively also maintain configuration standards across 27 00:03:23,260 --> 00:03:29,940 disparate network platforms and buildings stronger and more self-sufficient. 28 00:03:29,980 --> 00:03:40,210 Net ops team programmable software based automation technologies can help your team better support your 29 00:03:40,210 --> 00:03:49,120 organization's digital in the team to use Gartner believes organizations that automate 70 percent of 30 00:03:49,120 --> 00:03:57,700 their network configuration change will reduce the number of unplanned network outages by more than 31 00:03:57,700 --> 00:04:08,300 half compared with those that automate less than 30 percent so way to automate your network why we need 32 00:04:08,300 --> 00:04:13,200 this one reusable scalable software defined. 33 00:04:13,220 --> 00:04:21,350 Automation gives you more control over and visibility into network resources as a result you can improve 34 00:04:21,380 --> 00:04:30,710 infrastructure availability stuff productivity network security and configuration compliance. 35 00:04:30,770 --> 00:04:34,630 Okay let's start with the productivity network. 36 00:04:34,640 --> 00:04:43,670 Automation will improve your team's ability to respond faster to increased demand for changes and also 37 00:04:44,300 --> 00:04:51,800 they will able they will be able to test and deploy changes automatically and they will be able to automate 38 00:04:52,170 --> 00:04:55,890 rapidity you and unpopular their tasks. 39 00:04:56,120 --> 00:05:05,710 When it comes to complaints and network automation will ensure continuous compliance with changing regulations. 40 00:05:05,750 --> 00:05:14,170 You can leave all configurations from a single platform and automatically test changes before committing. 41 00:05:14,180 --> 00:05:19,690 You can also validate that changes were made appropriately or not. 42 00:05:19,910 --> 00:05:27,530 When it comes to security point of view you will be able to identify vulnerabilities and implement fixes 43 00:05:27,620 --> 00:05:30,850 across your entire network. 44 00:05:30,890 --> 00:05:39,980 You can collect information about network to ISIS and the build an inventory of those devices so you 45 00:05:39,980 --> 00:05:45,980 can automatically mitigate the issues when it comes to availability. 46 00:05:45,980 --> 00:05:55,340 You can increase network availability with more effective testing and management and also you can automate 47 00:05:55,340 --> 00:06:03,890 testing to better understand and the impact of change and reduce manual errors with automated change 48 00:06:04,100 --> 00:06:04,790 management.
