1 00:00:08,046 --> 00:00:10,240 After watching this video, you will be able to: 2 00:00:10,240 --> 00:00:14,160 Define DevOps, and describe the essential characteristics of DevOps. 3 00:00:15,600 --> 00:00:19,280 What is this DevOps all about? One thing is for sure, 4 00:00:19,280 --> 00:00:24,400 it is an overused "buzzword" in the industry. If you ask 10 people to define DevOps, 5 00:00:24,400 --> 00:00:29,040 you will get 11 different answers. Because of this ambiguity, let’s go back 6 00:00:29,040 --> 00:00:32,649 to its inception and work our way forward. 7 00:00:32,649 --> 00:00:38,800 In 2009, Patrick Debois coined the term “development operations.” He said, “Development 8 00:00:38,800 --> 00:00:44,320 operations is an extension of Agile development environments that aims to enhance the process of 9 00:00:44,320 --> 00:00:48,960 software delivery as a whole.” It is an extension of Agile. 10 00:00:48,960 --> 00:00:54,000 We are going to talk about what Agile did for the Devs and how it did nothing for Ops. 11 00:00:54,000 --> 00:00:59,680 Patrick Debois is saying, “What if we applied Agile to Ops? What if we treat them the same?” 12 00:00:59,680 --> 00:01:02,480 This is why sometimes I'll call DevOps “Agile for Ops.” 13 00:01:03,040 --> 00:01:07,920 This makes the Ops as Agile as the Devs by working together for a common goal. 14 00:01:07,920 --> 00:01:12,400 Patrick Debois was just saying that Dev and Ops can and should work together. 15 00:01:13,600 --> 00:01:20,240 DevOps is a recognition that development and operations must stop working in silos. 16 00:01:20,240 --> 00:01:25,840 They have to start working together. I like to say DevOps is the practice 17 00:01:25,840 --> 00:01:28,560 of development and operation engineers working together 18 00:01:28,560 --> 00:01:34,400 during the entire development lifecycle, following lean and Agile principles that allow them to 19 00:01:34,400 --> 00:01:40,720 deliver software in a rapid and continuous manner. I want to do it fast. I want to do it continuous. 20 00:01:40,720 --> 00:01:46,240 And I want to do it with Dev and Ops both together through the entire software lifecycle. 21 00:01:46,880 --> 00:01:50,320 To do that, we need to change to a culture of collaboration that 22 00:01:50,320 --> 00:01:56,960 values openness, trust, and transparency. We must adopt a new application design 23 00:01:56,960 --> 00:02:03,040 that does not require entire systems to be redeployed just to add a single function. 24 00:02:03,680 --> 00:02:07,840 You are not going to be able to deploy these large, monolith applications 10 times a day. 25 00:02:08,720 --> 00:02:14,400 We need automation that accelerates and improves the consistency of application delivery 26 00:02:14,400 --> 00:02:18,240 so that we can deploy and deliver our software with speed and stability. 27 00:02:19,520 --> 00:02:23,680 Once we take that application and we split it up into lots of little microservices, 28 00:02:24,240 --> 00:02:29,440 no human can deploy it anymore, so we need automation to automate the deployment 29 00:02:29,440 --> 00:02:33,440 of all those tiny microservices. We solve some problems with applications. 30 00:02:33,440 --> 00:02:37,840 We create some new problems with microservices. We solve those problems with 31 00:02:37,840 --> 00:02:44,000 automation. Happens all the time. Finally, you need a dynamic software-defined 32 00:02:44,000 --> 00:02:50,240 programmable platform to continuously deploy onto. You cannot be waiting days or weeks for somebody 33 00:02:50,240 --> 00:02:54,400 to provision a server and configure that server so that you can deploy your application. 34 00:02:54,400 --> 00:02:57,760 You have to say, “I need an environment and I need it now.” 35 00:02:58,400 --> 00:03:03,840 You get that environment to come up, deploy your app, and your software is up and running. 36 00:03:04,720 --> 00:03:12,160 It's important to understand what DevOps is not. DevOps is not just Development and Ops 37 00:03:12,160 --> 00:03:15,200 working together. It is a cultural change. 38 00:03:16,000 --> 00:03:18,800 DevOps is not simply combining the Dev team and the Ops team and you’re done. 39 00:03:20,640 --> 00:03:25,520 DevOps is not a separate team. I have seen companies make DevOps teams. 40 00:03:25,520 --> 00:03:28,880 It is not a separate team. If you know anything about Agile, 41 00:03:29,600 --> 00:03:33,600 you do not make an Agile team. You don’t say, “Oh, we have that team over there. 42 00:03:34,160 --> 00:03:40,000 They are the agile team. They make us Agile." No. Instead, the company becomes Agile. 43 00:03:40,560 --> 00:03:42,480 DevOps is not a team. It’s just like Agile. 44 00:03:43,840 --> 00:03:47,120 And DevOps is not a tool. There are many tools that support DevOps. 45 00:03:47,120 --> 00:03:51,680 These tools can reinforce your DevOps culture but they will not change your culture. 46 00:03:51,680 --> 00:03:55,360 You cannot become DevOps by simply buying a set of tools. 47 00:03:56,800 --> 00:04:00,880 There is no one-size-fits-all strategy. This is what makes it difficult. 48 00:04:00,880 --> 00:04:05,200 You must find out what works for your business. Are you shipping shrink wrap software? 49 00:04:05,200 --> 00:04:08,560 Do you provide software as a service? Is your product a software that people 50 00:04:08,560 --> 00:04:12,160 download and install themselves? It will be different based on what 51 00:04:12,160 --> 00:04:15,040 you are delivering, and you might not be delivering software at all. 52 00:04:15,040 --> 00:04:18,240 You might be delivering a service that software just enhances. 53 00:04:19,600 --> 00:04:25,040 So, it’s really important. Finally, DevOps is not just about automation. 54 00:04:25,040 --> 00:04:28,480 This is the one where the DevOps engineer jobs come in. 55 00:04:28,480 --> 00:04:31,920 People think that if they hire somebody who knows all the DevOps tools, 56 00:04:31,920 --> 00:04:34,880 then that person can automate everything and make them "DevOps." 57 00:04:36,560 --> 00:04:40,400 This is not DevOps. The Devs are still doing the same thing. 58 00:04:40,400 --> 00:04:43,600 This is not just Ops automation. That’s all it is, automating Ops. 59 00:04:44,320 --> 00:04:50,320 DevOps is not just Dev and it's not just Ops. It's DevOps. One word, one team, 60 00:04:50,320 --> 00:04:51,600 one set of measurements. 61 00:04:54,160 --> 00:04:58,080 In this video, you learned that: DevOps is not just Dev and Ops working 62 00:04:58,080 --> 00:05:03,840 together while remaining in their separate silos. DevOps is a cultural change in which development 63 00:05:03,840 --> 00:05:09,840 and operations engineers work together during the entire development lifecycle.
