There is no definite definition for a DevOps engineer. DevOps engineer is anyone who works in DevOps culture. Well, the main objective of a DevOps engineer is to oversee the code releases. For that, he will work with software developers, testers, system operators, etc. to be successful DevOps engineer. DevOps also emphasizes the key aspect of automating any uninteresting and error-prone tasks using a range of modern engineering tools. This article will help you gain insights on 12 specific skills set one needs to master in this space. One thing to continue to be in mind when you talk about a “DevOps engineer“ is that it is not a role but a skill set that requires to be mastered by every software developer and not just operation folks.
1. Linux Fundamentals and Scripting
To automate the infrastructure automation as a DevOps engineer, you must be familiar with at least one scripting language. Most of the Companies are working on Linux and they need experts with hands-on expertise on various tools like Puppet, Chef, and Ansible etc. To become a great DevOps engineer, you should knowledge of basic Linux ideas too and the scripting language could be Python, Ruby, and PERL etc.
2. Soft Skills
As mentioned above being a DevOps engineer is no one-man job, so in that case, any future employee should have soft skills as well as technical. Bound on trust, DevOps culture authorize all workers to be communicative and understanding to the process and if changes require to be made. When developers are in touch with each other effectively, applications can be delivered in a much shorter term of time than if some workers were absent to information. As well as quicker market arrangement, having good communication will lead to fewer errors and therefore lower costs and develop the quality of code.
Decisiveness or decision-making is one of the key elements employers look for in their employees. The ever-changing nature of the code in the DevOps team should be handled by a person who is rapid in taking decisions. Thus enabling rapid delivery and deployment of new code. Faster deployments give faster returns to the customer and provide immediate reaction from the end-users. This often leads to customer satisfaction.
DevOps engineers do not work for personal goals. They have team goals. Any problem is everyone’s problem. DevOps engineers should help to assist coworkers in their issues. The key is to have empathy towards others. Another point is, DevOps engineers work in little batches from performing code testing. It permits coworkers to do their job easily.
5. Infrastructure as Code:
Infrastructure as code (IaC) is kind of IT infrastructure allows operations and developers team to manage and provision computer data center automatically through code. So, if you are going to be the part of DevOps engineer’s interview, then make sure you should have this skill.
6. Knowledge of DevOps tools and techniques
DevOps involves multiple stages and there is a wide range of tools available for every stage. Here, it is necessary to have depth knowledge of development, testing, and deployment technologies.
- For Source control, you may use Git.
- For continuous integration, you may make use of Jenkins.
- For infrastructure automation, Ansible, tools like Puppet and Chef are optimum.
- For orchestration and deployment automation, you may make use of VSTS or Jenkins.
- For container concepts, Docker is the greatest choice.
- For cloud deployment, there are multiple choices like AWS, Azure, Google Cloud, Open Stack etc.
- For orchestration purpose, Kubernetes or Swarm is best.
A great DevOps engineer is always curious to learn new things. He or she must constantly ask questions and listen to answers to generate ideas. He should know how to welcome new challenges gracefully.
DevOps is a fairly current field and is constantly maturing. A DevOps engineer must be open to these changes and be able to adapt rapidly. Especially, those who have worked with the traditional approaches could find themselves in an unknown territory.
8. DevOps Key Concepts
DevOps is a culture where business, development, and operations teams collaborate breaking the traditional pit. The basic value is to create a cross-functional team that knows what each team member does and where any team member can take up the work of the other, thus providing that a better collaboration within group members and delivering a high-quality product to the customer. Since we don’t have silos anymore, unwanted time spent on transfer of the code between various teams like the testing team, the operation team is making less, increasing the pace of delivery.
Another basic concept is automating everything. This is done to generate a high-quality product for the customers by make less human defects.
9. Customer-first mindset
DevOps emphasizes on a customer-first mindset. All people who adopt DevOps should take decisions safe keeping this in mind. No project should be performed that does not add value to the customer.
10. Security skills
DevOps is all about speed, quality, and automation. As we increase the speed often we encounter passiveness that get introduced into the code at a faster pace. DevOps practitioners should be able to write the code that is protected from several of attacks. This has often led to DevSecOps thinking where security attributes are incorporated from the beginning rather than repairing it at the end.
11. Agile engineering
DevOps was introduced in 2008 by Patrick Debois and Andrew Clay Shafer after a discussion about agile infrastructure. Therefore DevOps is extremely rooted in agile principles and values. There are 4 agile values and 12 principles according to the Agile Manifesto. Every DevOps practitioner requires having an in-depth understanding of agile philosophies. Practical knowledge of agile practices like Test-driven improvement, behavior-driven improvement, etc helps to make a great DevOps practitioner.
12. Big Picture Thinking
Usually, software engineers are transitioned to the role of a DevOps engineer, sometimes, he lacks the ability to look at the big picture and not able to identify what makes sense for the client. While working with large enterprises, a DevOps engineer cannot lose sight of the big picture and digital transformation at the enterprise level. It helps to avoid the creation of contention points or constraints that carry from one project to the next.
DevOps is all about breaking down silos and where development teams, operation teams, and business teams collaborate to deliver a high-quality product rapidly. All team members where DevOps is approved should have all the 12 DevOps engineering skills. He/she focuses on customer satisfaction bit than local optimizations. To summarize, he/she should be a great team player, technically strong with good knowledge of DevOps tools and who can adapt to changes. This nice but important combination of all the attributes is important for a professional to be a DevOps engineer. Because, at the end of the day, customer satisfaction is the basic to running a successful business enterprise.
