1 00:00:07,410 --> 00:00:10,930 After watching this video, you will be able to define DevOps, 2 00:00:10,930 --> 00:00:16,070 identify misconceptions about DevOps, and recognize the best approach for teams using 3 00:00:16,070 --> 00:00:17,147 DevOps. 4 00:00:17,372 --> 00:00:20,889 The term DevOps is often misunderstood. 5 00:00:20,889 --> 00:00:25,680 For example, this drop-down list that I saw recently while signing up for a webinar. 6 00:00:25,680 --> 00:00:31,630 It asked for my job function and provided the options of DevOps/Technical Ops or Software 7 00:00:31,630 --> 00:00:32,630 Developer/Engineer. 8 00:00:32,630 --> 00:00:35,530 I’m a software engineer who practices DevOps. 9 00:00:35,530 --> 00:00:40,120 These job titles don’t reflect DevOps and frankly, this organization should know better. 10 00:00:40,120 --> 00:00:45,440 Clearly, they did not notice the letters “D-E-V” in DevOps, which stand for “development.” 11 00:00:45,440 --> 00:00:49,840 Here is a clue, if you’re not doing development, you’re not doing DevOps, you’re just 12 00:00:49,840 --> 00:00:50,840 doing Ops. 13 00:00:50,840 --> 00:00:53,899 They apparently did not understand this. 14 00:00:53,899 --> 00:00:57,489 There are both Dev and Ops in software development. 15 00:00:57,489 --> 00:01:01,620 For them, DevOps/Technical Ops is something that the Ops people do. 16 00:01:01,620 --> 00:01:06,650 But DevOps is not something that just Ops people do. 17 00:01:06,650 --> 00:01:08,710 There are different perspectives of DevOps. 18 00:01:08,710 --> 00:01:12,970 You start with traditional development and operations that have a wall of confusion between 19 00:01:12,970 --> 00:01:14,430 them. 20 00:01:14,430 --> 00:01:19,539 Many organizations, like this webinar organization from my example, think that DevOps is something 21 00:01:19,539 --> 00:01:24,500 the Ops people do, and that DevOps is a subset of operations. 22 00:01:24,500 --> 00:01:28,360 Some organizations think that DevOps is something developers do. 23 00:01:28,360 --> 00:01:33,180 But most organizations think DevOps is a separate team that sits between Dev and 24 00:01:33,180 --> 00:01:35,150 Ops and keeps both of them happy. 25 00:01:35,150 --> 00:01:38,050 I’m going to talk more about that in a moment. 26 00:01:38,050 --> 00:01:40,030 None of these perspectives are correct. 27 00:01:40,030 --> 00:01:44,430 DevOps is a mindset that the whole organization adopts. 28 00:01:44,430 --> 00:01:45,610 You will see this a lot in start-ups. 29 00:01:45,610 --> 00:01:47,850 DevOps is their company culture. 30 00:01:47,850 --> 00:01:54,750 It’s Dev and Ops working together with the same mindset, preferably on the same team, 31 00:01:54,750 --> 00:01:58,130 using the same goals and measurements. 32 00:01:58,130 --> 00:02:03,360 Jez Humble wrote, “The DevOps movement addresses the dysfunction that results from organizations 33 00:02:03,360 --> 00:02:05,550 composed of functional silos. 34 00:02:05,550 --> 00:02:10,780 Thus, creating another functional silo that sits between Dev and Ops is clearly a poor 35 00:02:10,780 --> 00:02:14,050 (and ironic) way to solve these problems.” 36 00:02:14,050 --> 00:02:17,970 Remember, there is no such thing as a DevOps team. 37 00:02:17,970 --> 00:02:23,030 That is an antipattern; it causes more problems than it would solve. 38 00:02:23,030 --> 00:02:27,690 You see, DevOps is the recognition that working in silos doesn’t work. 39 00:02:27,690 --> 00:02:31,470 You may have seen this “wall of confusion” graphic, made famous by Andrew Clay Shafer. 40 00:02:31,470 --> 00:02:37,340 It depicts the diametrically opposed goals of development and operations. 41 00:02:37,340 --> 00:02:40,500 Development is measured by how many new features they can push to production. 42 00:02:40,500 --> 00:02:45,110 Operations, on the other hand, is measured by how stable production is. 43 00:02:45,110 --> 00:02:50,980 One way to stabilize production is to not change anything, like adding new features. 44 00:02:50,980 --> 00:02:55,760 If you create a separate DevOps team, you are just creating another silo that further 45 00:02:55,760 --> 00:02:57,300 separates Dev and Ops. 46 00:02:57,300 --> 00:03:00,390 This doesn’t make any sense when you look at it this way. 47 00:03:00,390 --> 00:03:04,760 You don’t create a team to make you DevOps any more than you would create a team to make 48 00:03:04,760 --> 00:03:06,210 you Agile. 49 00:03:06,210 --> 00:03:10,710 No one forms an Agile team and claims that their organization is suddenly Agile because 50 00:03:10,710 --> 00:03:12,180 of that team over there. 51 00:03:12,180 --> 00:03:16,810 No, the organization must adopt the Agile mindset, becoming Agile. 52 00:03:16,810 --> 00:03:19,460 DevOps is no different. 53 00:03:19,460 --> 00:03:22,320 The reality is that DevOps is not a job title. 54 00:03:22,320 --> 00:03:25,880 It is not something one person does, or a team does. 55 00:03:25,880 --> 00:03:29,870 It is a cultural transformation on an organizational scale. 56 00:03:29,870 --> 00:03:34,880 It is the practice of development and operations engineers working together during the entire 57 00:03:34,880 --> 00:03:41,290 software lifecycle, preferably on the same team, following Lean and Agile principles 58 00:03:41,290 --> 00:03:46,410 that allow them to deliver high-quality software stably and continuously. 59 00:03:46,410 --> 00:03:50,900 It starts with learning how to work differently and embracing cross-functional teams with 60 00:03:50,900 --> 00:03:54,970 openness, transparency, and trust as pillars. 61 00:03:54,970 --> 00:04:00,770 If that doesn’t sound like your organization, then you are probably not practicing DevOps. 62 00:04:00,770 --> 00:04:06,240 In this video, you learned that DevOps is a mindset that the whole organization adopts. 63 00:04:06,240 --> 00:04:09,850 DevOps solves the problems caused by siloed teams. 64 00:04:09,850 --> 00:04:14,580 DevOps is the practice of development and operations engineers working together during 65 00:04:14,580 --> 00:04:20,470 the entire software lifecycle, following Lean and Agile principles that allow them to deliver 66 00:04:20,470 --> 00:04:22,507 high-quality results.
