4. Introducing DevOps for Amateurs & Pros The DevOps philosophy emphasizes collaboration and communication between Development and Operations teams in order to achieve a seamless software development process. The term "DevOps" is a combination of "Development" and "Operations," reflecting the integration of these two critical functions in IT organizations. The equation is simple, DevOps = Dev + Ops It is characterized by its focus on lean IT ideas, short iterations during the software development process, emphasis on continuous delivery, and eforts to eliminate waste. Recent surveys report that organizations implementing DevOps practices have seen significant improvements in their software development and delivery processes, including faster time-to-mar- ket, increased efciency, and improved software quality. These results have further solidified DevOps as a highly valuable and in-demand career path for IT professionals. According to the Global DevOps Market Research Report (2021 to 2026) The Global DevOps Market size was estimated at USD 4,311.95 million in 2020 and is estimated to reach USD 12,215.54 million by 2026 with a CAGR of 18.95%. 04

5. DevOps adoption across Startups and Big Corporates So, you're curious about which companies are hopping on the DevOps train, eh? Well, buckle up, because the answer might surprise you! According to a recent survey by the DevOps Institute, 70% of organizations have either fully embraced DevOps or are in the process of implementing it. Another study by the Information Systems Audit and Control Association (ISACA) found that 85% of organizations are now using DevOps as part of their software development process. DevOps practices are not just in for tech giants, it's a trend that's catching fire in companies of all sizes and industries. From finance to healthcare, retail to manufacturing, businesses are realizing the benefits of DevOps and embracing its practices to improve their software delivery processes. Start-ups are early adopters of DevOps because of the agility and speed that it provides. For example, Airbnb, a leading hospitality company, adopted DevOps early on to help them quickly bring their products to market. Big corporations, on the other hand, are also adopting DevOps to stay competitive in a rapidly changing market. For example, Walmart, a multinational retailer, adopted DevOps to increase the efciency of its development and deployment process. According to a study by Puppet, high-performing DevOps teams can deploy code up to 200 times more frequently than low-performing teams. 05

High salaries: In metropolitan cities such as Mumbai, Bengaluru, and Delhi, the salary for DevOps professionals can range from ₹12-18 lakhs per year. Highly skilled and experienced DevOps professionals can earn even more, with salaries exceeding ₹20 lakhs per year. Prerequisites Before Beginning a DevOps Journey The primary requirement for aspiring DevOps professionals is to know what DevOps is and what it is not! You need some technical spears and anchors to jump to the land of endless possibilities. Let’s check them one by one. DevOps is a culture, not a tool or job title, that prioritizes cost-efective and productive methods in software development by breaking down traditional silos. So, aspiring DevOps professionals need a thorough understanding of the Software Development Life Cycle (SDLC). Next, to build a career in the DevOps sphere, you are expected to have a solid understanding of software development methodologies, such as Agile, which are essential for efective DevOps practices. Knowledge of infrastructure management and deployment, as well as experience with virtualization and cloud computing technologies, is also important for understanding how DevOps practices can be applied to infrastructure management. Also, automation is a key aspect of DevOps, and understanding how to automate processes and systems is critical to success in this field. And since an experience with scripting languages, such as Python, is important for automating processes and systems, it becomes a prerequisite too. 07

8. Cross-training is also essential for aspiring DevOps professionals. Software developers should explore beyond their comfort zone of development into the operations domain and vice versa. Knowledge of CI/CD pipelines and how to implement them is equally crucial for efectively implementing DevOps practices. Moreover, a strong understanding of Linux/Unix administration is important for understanding how to manage systems and applications in a DevOps environment. Besides these technical skills, you also require efective communication and collaboration skills for working in a cross-functional DevOps team. As a DevOps professional, you are expected to gain mastery in the following DevOps tools: GitLab, GitHub, and Bitbucket for version control Maven as a build tool Jenkins for Continuous Integration Chef, Ansible, and Puppet for Configuration Management Container platforms like Docker Orchestration and container platforms like Kubernetes Communication and collaboration tools like Slack 08

As a DevOps beginner, you are not expected to know everything in a single go. You start learning DevOps by discovering what it is, its traits, and essentials. Also, you grow by appreciating the benefits it ofers. At an organizational level, you start experimenting with DevOps practices by applying them to one single service or application. You can set team metrics and then monitor and report them. Through DevOps you make development and operations teams talk to each other and collaborate with each other. Further, you analyze how DevOps is making a diference to your workflow as against the traditional approach of product development. 15

16. Do DevOps need coding? Yes. Usually, for most organizations, DevOps engineers write code in Linux, Python, on AWS or any other platform. Applications cannot be built without code it is code that tells what the applications should do. If you do not write or rewrite the code the application will not change to reflect changing requirements. Though there is a thin line between configuring software and coding you are expected to have coding skills. What are DevOps examples? DevOps means diferent things to diferent people. If we must document well-known DevOps examples, a typical DevOps example will comprise: • • • • Continuous Integration of Code into a master repository on a day-to-day basis Automated testing of code and debugging errors early in the development stage Continuous monitoring and improving performance Collaboration and building teams with shared goals and wide responsibilities. How do I start from scratch? DevOps is not something new out of the air. Also, it is not a magic wand to solve all software problems. The activities used by DevOps practitioners are already in use at the workplace. It is all about doing better at something you already do at the workplace. Initiating a DevOps journey can be done with a pilot project in one part of the organization. DevOps is all about patience and changing people's behavior, it is never instant. What are good DevOps tools? DevOps predominantly administers automation, but it is way beyond that. To implement DevOps practices, various tools are needed. We can categorize them as: • • • • • • Source code management tools Continuous Integration and Continuous Delivery tools Configuration management tools Containerization platforms Orchestration tools Monitoring, security management, and intrusion detection tools Popular tools in these categories are Ansible, Puppet, Chef, Kubernetes, Jenkins, Maven, Git, and Slack. 16

17. Is DevOps only for the cloud? DevOps and the Cloud are inseparable, they work well in tandem. Cloud computing is so pervasive that it is difcult to point out an organization not having its presence in the cloud. Though organizations can use the traditional waterfall model to develop and deploy projects, it is equally possible to employ full-on DevOps to build, release, and support applications to run on IT hardware within your organization. Embracing DevOps practices to deploy cloud applications has innate advantages like eliminating the need to account for resources utilized, the automation implemented with DevOps is increasingly cloud-centric, the cloud’s centralized nature is an added advantage to DevOps practitioners as they can centrally develop, test, and release software products.
