1 00:00:00,530 --> 00:00:05,720 In this video, we are going to talk about what is infrastructure as code. 2 00:00:06,890 --> 00:00:14,660 So infrastructure is code or IAC is the process of provisioning and managing infrastructure defined 3 00:00:14,660 --> 00:00:18,110 through the code instead of doing bit manual process. 4 00:00:19,430 --> 00:00:22,040 So as infrastructure is defined as code. 5 00:00:22,070 --> 00:00:28,370 It allows users to easily edit and distribute configurations while ensuring the desired state of the 6 00:00:28,370 --> 00:00:29,330 infrastructure. 7 00:00:29,900 --> 00:00:34,550 So this means you can create reproducible infrastructure configurations. 8 00:00:36,300 --> 00:00:36,810 InfoSec. 9 00:00:36,820 --> 00:00:42,300 Today's code is a process that automates the provisioning and management of the cloud resources. 10 00:00:43,530 --> 00:00:47,300 InfoSec code software takes some input secrets. 11 00:00:47,310 --> 00:00:55,230 This software is the software and take some input scripts describing the desired state and then communicates 12 00:00:55,230 --> 00:00:56,550 with the cloud vendors. 13 00:00:56,550 --> 00:01:02,760 Typically they are using through APIs in order to make the royalty match the desired state. 14 00:01:02,760 --> 00:01:09,900 So that means we are writing desired state as a script and we basically connect with any cloud vendors. 15 00:01:09,900 --> 00:01:18,810 It could be Azure and Google and we can communicate through the APIs and provision the desired state 16 00:01:18,810 --> 00:01:27,300 according to script and make it reality sometimes referred to as a programmable infrastructure. 17 00:01:27,510 --> 00:01:31,110 IAC configures infrastructure exactly like programming. 18 00:01:31,110 --> 00:01:36,060 So Face It uses descriptive coding language that automates the process. 19 00:01:37,300 --> 00:01:44,470 So with latest technologies like virtualization and the cloud, it is combined with the rise of the 20 00:01:44,470 --> 00:01:50,890 DevOps and Agile practices, and it makes shortening the software development lifecycle dramatically. 21 00:01:51,490 --> 00:01:56,020 As a result, there was a demand for better infrastructure management techniques. 22 00:01:56,230 --> 00:02:02,320 Organization could no longer afford to wait for hours or days for servers to be deployed. 23 00:02:02,560 --> 00:02:09,100 So infrastructure is code is the only way of raising standards of infrastructure management and time 24 00:02:09,100 --> 00:02:09,820 to deploy. 25 00:02:10,420 --> 00:02:17,020 By using a combination of tools, language, protocols and processes, infrastructure as code can safely 26 00:02:17,020 --> 00:02:20,230 create and configure infrastructure elements in a second. 27 00:02:22,050 --> 00:02:27,800 So we can talk about the benefits of infrastructure discord with automated process. 28 00:02:27,810 --> 00:02:30,990 IAC helps business manage their I.T. 29 00:02:31,020 --> 00:02:33,210 Infrastructure needs in several ways. 30 00:02:33,880 --> 00:02:39,700 And organization using the IAC experiments for kind of expert benefits. 31 00:02:39,700 --> 00:02:43,660 I would like to give some of the benefits and the first benefit is speed. 32 00:02:44,970 --> 00:02:51,150 Speed is alluding to manual intervention and infrastructure deployments are quickly unsafe. 33 00:02:51,330 --> 00:02:55,200 We can avoiding manual intervention model configuration. 34 00:02:55,200 --> 00:02:56,880 It makes us more speedy. 35 00:02:57,780 --> 00:03:00,050 And also IAC transform developers. 36 00:03:00,060 --> 00:03:06,390 Time consuming provisioning works into a simple script execution in order to have their infrastructure 37 00:03:06,390 --> 00:03:06,870 ready. 38 00:03:07,530 --> 00:03:13,530 So infrastructure as code enables you to quickly set up your complete infrastructure by running a script. 39 00:03:14,820 --> 00:03:21,390 You can do that for every environment, from development to production, pacing through, staging and 40 00:03:21,390 --> 00:03:21,840 more. 41 00:03:21,870 --> 00:03:28,560 We can define a parameter as an environment and we can run the same circuit for several environments. 42 00:03:29,040 --> 00:03:34,320 Also, infrastructure as code can make the entire software development lifecycle more efficient. 43 00:03:34,410 --> 00:03:40,860 As a result, application deployments no longer have to wait for the infrastructure, and new software 44 00:03:40,860 --> 00:03:42,700 can be released much more quickly. 45 00:03:42,720 --> 00:03:45,420 It becomes us comes with the speed. 46 00:03:46,260 --> 00:03:48,810 The second benefit is the consistency. 47 00:03:49,260 --> 00:03:56,010 So deploying identical infrastructure across the board, avoiding edge cases and one of configurations 48 00:03:56,010 --> 00:04:01,660 make comes with the consistency and manual processes result in mistakes. 49 00:04:01,680 --> 00:04:05,910 At some period you can get mistakes with the manual processing. 50 00:04:06,030 --> 00:04:10,450 Humans are can get fails when deploying the applications. 51 00:04:10,470 --> 00:04:15,510 Our memory is faultless, so communication is hard and we are in general pretty bad. 52 00:04:16,290 --> 00:04:22,620 So infrastructure is code solves that kind of problems by having the config files themselves to be a 53 00:04:22,620 --> 00:04:24,240 single source of truth. 54 00:04:24,570 --> 00:04:31,500 So by that way, you guarantee the same configuration will be deployed over and over again without any 55 00:04:31,500 --> 00:04:32,640 getting exception. 56 00:04:33,780 --> 00:04:37,350 So that means the third benefit is reusability. 57 00:04:37,470 --> 00:04:43,590 Infrastructure is code, makes it easy to create reusable models, for example, to replicate development 58 00:04:43,590 --> 00:04:45,180 and production environments. 59 00:04:45,720 --> 00:04:48,150 And another benefit is reduced. 60 00:04:48,150 --> 00:04:55,410 The cost infrastructure is code ALOS virtual machines to be managed programmatically and eliminating 61 00:04:55,410 --> 00:04:58,800 the need of manual hardware configurations and updates. 62 00:04:59,630 --> 00:05:05,850 One operator can deploy and manage one machine or a thousand machine using the same set of code. 63 00:05:05,870 --> 00:05:12,170 So that means that people, staff are needed and purchasing new hardware is no longer necessary. 64 00:05:12,200 --> 00:05:18,410 Reducing cost is significantly and another benefit is source control. 65 00:05:18,470 --> 00:05:23,480 Code can be checked in the source control for increased transparency and accountability. 66 00:05:24,290 --> 00:05:29,750 Infrastructure is called can improve consistency and reduce errors that often happen during the manual 67 00:05:29,750 --> 00:05:30,680 configuration. 68 00:05:30,920 --> 00:05:37,700 It also eliminates any configuration drift that might occur during the manual process by codifying and 69 00:05:37,700 --> 00:05:40,490 documenting your configuration specifications. 70 00:05:40,580 --> 00:05:45,890 Infrastructure as code helps you to avoid undocumented and adult configuration chains. 71 00:05:47,010 --> 00:05:54,030 And the last one, of course, Agility DevOps has made software delivery more efficiently, and infrastructure 72 00:05:54,030 --> 00:05:58,080 as code brings agility to the realm of the infrastructure management. 73 00:05:59,500 --> 00:06:06,590 P.S. In the image on the slide, how infrastructure is called works infrastructure is quote can be explained 74 00:06:06,590 --> 00:06:13,250 from the high level in three simple steps and visualize with the diagram you can see the diagram. 75 00:06:13,250 --> 00:06:15,550 We have three steps and four. 76 00:06:15,590 --> 00:06:21,740 First step is developers write the infrastructure specification in the domain specific language. 77 00:06:21,770 --> 00:06:26,570 You can write secret templates in the domain specific language. 78 00:06:27,110 --> 00:06:35,150 And second step is the resulting files are sent to master server and management API or code repository. 79 00:06:35,480 --> 00:06:39,170 You can manage these scripts into the these tools. 80 00:06:39,170 --> 00:06:46,160 And the last one is the platform takes all the necessary steps to create and configure provisioned your 81 00:06:46,160 --> 00:06:47,630 desired infrastructure.
