How to Become a DevOps Engineer?

“The
Most Powerful Tool We Have as Developers is Automation” – Scott Hanselman

DevOps engineer jobs are ranked 2nd on Glassdoor’s 50 best jobs in America. Salary of leading DevOps engineers can be between $137,00 and $180,000. These figures are obtained from April 2018 job data from Glassdoor.

Whether you are a developer, a QA guy, an Ops professional, or maybe a fresher; you can become a DevOps engineer. In this post, you are provided with a roadmap to become a DevOps engineer.

What is DevOps and Who is a DevOps Engineer?

DevOps is a software development system, which overcomes any issue between the developers and the IT staff. With DevOps, organizations can discharge little features in all respects rapidly and join the criticism, which they get in all respects rapidly. Following are some different advantages:

· Less software failure

· Shortened lead time between fixes

· It beats every one of the constraints of the conventional development model

DevOps Engineer

A DevOps engineer person with understanding of Software Development Lifecycle and different automation tools for the development of digital pipelines (CI/CD). DevOps Engineer works with developers and the IT staff to administer the code releases. They are either developers who get keen on deployment and network tasks or SysAdmins who have an energy for scripting and coding and move into the development side where they can improve the arranging of test and deployment.

DevOps Engineer Roadmap

Here, I will list down the important skills that an organization looks for in a DevOps engineer:

• Understanding of Linux and Scripting
• Hand-on experience of various development, testing,
  and deployment technologies (Tools
  such as Git, Jenkins, Docker, Kubernetes, Puppet, Chef, Splunk, etc.)
• Experience in developing CI/CD pipelines
• Sound knowledge of concepts such as Infrastructure as Code
• Familiarity with cloud service platforms such as AWS, Azure,
  and GCP

Consider the following roadmap:

1. Knowledge about Linux

To start your journey on the DevOps roadmap, this is the foremost
skill that you should possess.Intermediate level knowledge of Linux administration is required because you will be working mostly on Linux
servers that run the applications and other components.

2. Scripting Knowledge

For automation of processes, sound knowledge of scripting
is required. Scripting language could be of any preference, however, bash scripting is the most common. Sound knowledge of scripting in any of bash, python, or perl will be sufficient enough.

3. Git (Version Control Systems)

Be proficient with at least one version control
system, preferably Git. By far, it is the most commonly used version control
system in the world. Git is a mature, actively maintained open source project
developed in 2005 by Linus Torvalds, the famous creator of the Linux Kernel.

4. Configuration Management Tools

CM tools are assumed a fundamental component in overseeing Infrastructure as Code. Experience in any of the configuration management tool, for example, Ansible, Chef, Puppet, and so on is expected out of a DevOps practioner. Configuration management tools help in automating your whole infrastructure by overseeing it through code simply like a typical programming.

5. CI/CD Tools

CI/CD is the principle around which DevOps revolves, therefor, knowledge on building pipeline tools such as Jenkins, Hudson, Travis, etc. is required. Jenkins is the most widely used pipeline tool.

6. Monitoring

Continuous monitoring is a part of DevOps standards. There are different monitoring tools in the market and most organizations utilize numerous monitoring tools to monitor their condition and alert when there is an error. Devices like nagios, icinga, datadog are utilized for infrastructure monitoring while tools like AppDynamics, New Relic are utilized for both infrastructure and application monitoring. Tools like Splunk, graylog, ELK are utilized for centralized monitoring of logs. Becoming more acquainted with any of these tools will assist you with understanding the principles of monitoring and effectively comprehend different products.

7. Cloud Service
Providers

Cloud has turned into the most common word in the recent years. Knowing extensively about the different services given by various cloud suppliers is necessary. You ought to be adept in using any one of the famous public cloud providers like AWS, Azure, Google Cloud, DigitalOcean and so forth. AWS is the most mainstream and broadly utilized cloud supplier. Completing AWS certification may help you pick up a broad information about AWS and the services it provides.

8. Containers

Containers are the new standard in DevOps. Knowledge of containers and container management services like Kubernetes, Docker Swarm, Apache Mesos and so on will upgrade your validity as DevOps Practitioner. Containers down the line may change the way how infrastructure deployment functions, so learning this has become mandatory to adjust for what’s to come.

Where Should You
Learn DevOps

To get the theoretical knowledge about all the stated tools
and skills, you can check their official websites and documentation. However,
this is not enough to be successful, you need to have hands-on experience and
for that, I would highly recommend you to study guides from IPSpecialist; their
publications contain all the necessary information and practice labs to get a
hands-on experience of the services that are discussed in the work books. 

Conclusion

Hopefully you enjoyed this post and found it informative. Keep in mind that there is more to DevOps than the things covered in this article. The purpose of this blog is provide a starting point for the people who are interested in building a career in DevOps. After reading this article, you should be familiar with DevOps and the role of a DevOps engineer. You are now technically equipped to adapt yourself when the situation demands.
