DevOps aims at coupling a tighter alignment between IT operations and business. This new phenomenon is taking over the corporate boardrooms by storm and bringing in new methodologies and principles to streamline the creation and deployment of software in the new ‘software is eating the world’ era.

In this blog post, we will delve into the aspects of what it takes to become a DevOps Engineer, what is the career opportunity available and what is the scope of the job of a DevOps Engineer. There is a general belief that DevOps is more about the automation of processes, the deployment of code and releases of software. But it is much more than that. So, in order to be a successful DevOps professional, you need to have both technical and non-technical skills in equal measure.

Who is a DevOps Engineer?

The DevOps Engineer has to manage the IT infrastructure as per the requirement of the supported software code that is dedicated in a hybrid multi-tenant environment. There is a need to have the required resources for provisioning and getting the appropriate deployment model and also validating and monitoring the performance.

When it comes to DevOps, there is a need to have frequent and incremental changes in the code versions so that the frequent testing and deployment are possible. It might not be always possible for DevOps Engineers to do the coding from scratch; they anyway need to know about it.

There is a need for DevOps Engineers to connect various elements of coding along with libraries and software development kits and integrating various components of SQL data management or messaging tools for running software release with operating system and production infrastructure.

Understanding the Role of a DevOps Engineer

As said earlier, the DevOps approach to software development requires frequent, incremental changes, and DevOps Engineers rarely code from scratch. However, they must understand the basics of software development languages and be familiar with the development tools used to create a new code or update the existing one.

A DevOps Engineer will work with development staff to tackle the coding and scripting needed to connect elements of the code, such as libraries or software development kits (SDKs) and integrate other components such as SQL data management or messaging tools that are needed to run the software release with operating systems and production infrastructure.

A DevOps Engineer must be able to manage an IT infrastructure as per the supported software code dedicated in multi-tenant or hybrid cloud environments. There is a need to have a provision for required resources and get the appropriate deployment model, validating the release and monitoring performance.

It could be either the developers who have moved into operations or the system administrators who have moved into the coding domain. Either way, it is a cross-function job role that is seeing huge upside in the way software is developed and deployed in mission-critical applications.

Roles of a DevOps Engineer

  • A firm knowledge of various computer programming languages. Familiarity with basic concepts of Linux will be helpful. It is good to have knowledge of any one scripting language as well.
  • Working with a variety of open-source tools and technologies for managing source codes.
  • Having a thorough knowledge of IT operations and sysadmin roles in order to strategize the entire integration and deployment process.
  • Expertise in software code testing and deployment. Handsome knowledge in development, testing, and deployment technologies will smoothen the journey of a DevOps Engineer.
  • Deploying various automation tools of DevOps to perfection. A DevOps Engineer is expected to have thorough knowledge of software development through automation tools.
  • A firm grounding in the agile methodology of project management. The agile methodology helps in continuous iteration of software development and testing.
  • Ability to connect to technical and business goals with alacrity.
  • Good skills in communication and working with teams.

Software today is not done in the old-fashioned way. Nowadays, it is all about open-source technologies and using the already existing pieces of code in order to stitch a computer program that can adhere to your specific needs. Thus, the role of a DevOps Engineer needs to evolve and adapt to the new shift in paradigm that is sweeping the world of software development life cycle and beyond.

The software has to meet the stringent requirements of a world where omni-channel digital interface is a must-have, and the code has to be adaptable and able to morph as per the changing needs of the business enterprise. Due to this, the process of testing and deployment is also seeing a sea change in the way it is managed. A DevOps Engineer has to face the challenge of the new world order and be able to deliver in a fast-paced world.

The DevOps Engineer has to ensure that the code has the changes which are frequent and incremental in nature. Thus, the DevOps Engineer must know about various elements of coding, along with the libraries and software development kit, so as to integrate different components of SQL data management or the messaging tools for software release with the operating system and the production infrastructure.

Significant Skills Required by a DevOps Engineer:

  • Be an excellent sysadmin

A system administrator is supposed to build, manage and troubleshoot the servers on a regular basis. Getting the servers to work right is one of the most important aspects of the job of a DevOps professional. Next comes the process of automating the key processes in server deployment and infrastructure deployment which are also the part of the skill set of a successful DevOps professional.

  • Deploy virtualization

The DevOps professional should be well-versed with the aspect of virtualization since he has to take charge of the entire process of virtualizing servers and other components. He should be able to work in a private or a public cloud set-up with ease and deploy the necessary infrastructure and virtualization.

  • Hands-on experience in network and storage

Today, network and storage are part and parcel of any IT organization, and hence the DevOps professional should be able to deploy his knowledge of the IT network and storage concepts. This comes in handy when there is a need to design solutions that can stand up to the test of scalability, performance and high availability at all times.

  • Knowledge of coding goes a long way

Did you know that coding is one of the few skills that will survive the onslaught of automation that we are seeing all around? So, having a basic knowledge of coding in any of the popular coding language can go a long way. It could be having a grasp of Python, Perl, Java, Ruby or any other language. This way, the DevOps professional can be a better bridge between the development and operations teams. Everybody knows that today everything is automatized including the server triggering, application installation, configuration and validation processes. So, there has to be a lot of coding that needs to be just right, and it is the responsibility of the DevOps professional to ensure that everything is working smoothly.

  • Soft skills are a must-have

This is also a primary requirement for the DevOps professional in order to be a bridge between the development and operations teams. Since DevOps is more of a cultural shift, there is a need to have right people skills and soft skills in order to get the whole organization move in a well-oiled fashion. Since for a long time the development and operations teams were at an arm’s-length, the DevOps principles is bringing about a sea change.

  • Security aspects of the IT organization

Security is one of the prime focus of a DevOps professional. Due to this, the DevOps personnel needs to know about various security measures that need to be taken care of in order to ensure that the system is safe and sound and running at all times.

There are a lot of automation processes that are deployed in the IT organizations which the DevOps personnel need to take special care of. DevOps ensures that the security aspect is taken care of due to the process of automation, increased visibility, fast updates, and the agile methodology of getting things done.

  • Knowledge of testing

Testing is one of the most important aspects of the software development and delivery process. So, the DevOps professional needs to understand how testing works in order to make the whole process of testing go in the right direction.

There are a lot of automation tools that are deployed for the process of testing, and the DevOps professional needs to have hands-on experience of working with these tools. DevOps is more about preventing errors rather than finding the errors.

Now, you know the most important skill set of a DevOps Engineer, but did you know that DevOps Engineers are among the highest paid professionals in the technology domain?

There is an acute need of professionals with the right set of DevOps skills in the DevOps domain. Today, DevOps has morphed into a very demanding domain with forward-thinking organizations deploying the code up to 30 times more often than their competitors. More than half of these deployments will succeed.

Have a look at some of the DevOps Engineer tools:

  • Git and GitHub – Version control system and source code management
  • Jenkins – Server automation and developing CI/CD pipelines
  • Selenium – Automated testing
  • Kubernetes – Container orchestration
  • Puppet – Configuration management
