DevOps Engineer - Job Description, Career Path, Salary and Skills
Overview
What is DevOps Engineering?
DevOps is formed with the combinations of Development(Dev) and Operations (Ops). The Development includes Coding, Testing, and Security while operations include the deployment and release of the final products. So in simple words, we can say that DevOps is a process that includes complete software development life cycle work.The main purpose behind this methodology is to bridge the gap between development and operation teams and increase the process of delivering a high-quality application in less time. And that's the only reason more and more organizations adopting this.
Under the DevOps model, the development and operation teams work together across the entire software application cycle including development, testing, and deployment. DevOps methodology works well with the agile methodology to fulfill its purpose.

What does a DevOps Engineer do?
The main job of DevOps engineers is to collaborate with the different teams (Development and Operation) and automate the whole software development life cycle for fast and reliable delivery.
Their main job includes:
1. Handling the code release2. Implementing CI/CD Pipeline3. Implementing and maintaining the cloud infrastructure4. Automation of various processes in software development life cycle5. Solving the issues arise during development, deployment or during maintenance6. Monitoring the product after deployment to catch new bugs, fix them quickly and deploy
What skills does a DevOps Engineer need?
A DevOps Engineer needs a specific set of interpersonal, tooling, and technical skills to become successful. Here is a list of the top must-have skills for a DevOps Engineer:
1. Knowledge of Linux fundamentals
Nowadays, most companies have their environment set up on Linux OS, and many DevOps tools like Chef, Puppet, and Ansible also need Linux knowledge. So, you should have good knowledge of Linux.
2. Knowledge of cloud service platforms
Most organizations use cloud services nowadays like AWS, Google Cloud Platform, or Azure. So, as a DevOps engineer, you must know different cloud technologies. You don't have to learn altogether. Learn at least one and then if required you can go with others. But you should know of one of them.
We recommend you join this Cloud Computing E-Degree to get master's in cloud computing.
3. Understanding of DevOps tools
DevOps is a process from development to deployment, so lots of tools are involved in it. Some of them are Git, Jenkins, Docker, selenium, Puppet, Chef, Ansible, etc. These tools are very important to complete DevOps tasks and fulfill the purpose of quicker delivery. So a DevOps engineer must know these tools.
4. Understanding of CI/CD Pipeline
Continuous Integration (CI) and continued Delivery (CD) can be considered the most important tasks for a DevOps engineer as the whole purpose is to reduce the delivery time. Continuous Integration is the process of integrating the new code pushed by the developer to the main repository.
Continuous Delivery is the process of releasing the validated code to a common repository. The purpose of Continue Delivery is to automate the release process. The tools you used for this are Jenkins, CircleCI, GitLab, etc.
5. Programming
As DevOps is a combination of development and operations, the knowledge of programming is a must for a DevOps engineer. Especially scripting languages like java, Python, PHP, Node JS, Ruby, etc. The scripting language will be helpful in automation work.
You don't have to be great in programming or need to learn all of these, but a good understanding of anyone is a must.
It will help you in understanding and debugging the code, and resolve errors during build and deployment. So, you don't have to go back to the development team for every error occurred and it will save time.
6. Knowledge of software configuration and deployment
As a DevOps engineer, your responsibility is to run all things smoothly. Also, you have to automate the various processes for reliable, consistent, and accurate delivery. So, you must know configuration and deployment of different software tools.
7. Understanding of Network and Security
As a DevOps engineer, you need to deal with various servers, connections, and data transfer, so you should have a better understanding of networking concepts.
DevOps engineer also needs to look into the security of all environments at every stage of the software lifecycle. DevOps is all about automation and faster delivery and often vulnerabilities also get introduced in the code during this process. So, as a DevOps engineer, you must keep the security concept in mind and need to implement it during each phase of automation.
8. Good Communication Skills
As a DevOps engineer, you need to work with different teams (Development, testing, and deployment). So, you need to make communication with everyone for better cooperation and collaboration. You need to bring all these teams together for a common goal (faster delivery), so your communication skills should be very strong.
9 Soft Skills
Along with your communication skills, there are other important soft skills also that you need to work on like Time Management, Decision Making, Leadership, etc. Having a good command over soft skills will not only help you in managing the different DevOps processes but also help you in your career growth and reduce work stress.
