How to become a DevOps engineer?

 

A DevOps engineer is a good career choice in 2021 as the demand for it is increasing considerably. The need for a skilled DevOps engineer is expanding within the market. But there are still some misconceptions and confusions regarding this career choice. Well, let's dig into this article to clear your doubts and confusion regarding DevOps engineers.

In this technology-driven era where information and data are fed into computers, almost every company is implementing cloud services to maintain their working professional environment. Learning DevOps is necessary if you are an aspirant with an IT background who aspires to be a part of the IT sector. Let's go from the basics to understand the career path of a DevOps engineer.

 

What is DevOps?

Before we understand what and who is DevOps engineer let's know and understand the importance of DevOps. One should know the importance of DevOps to understand the role of DevOps engineers. DevOps is defined as an approach or practice that bridges the gap or combines the software development (Dev) and IT operations (op). There isn't a universal definition for DevOps created by academics and practitioners other than its use to refer to the cross-functional combination. It is applicable in a different context, but it is mainly characterized by combination or shared ownership, which aims at the same goal.

 

With DevOps, organizations aim to develop an agile relationship between software and IT to create and release features and regular updates and incorporate feedback much more quickly than the traditional waterfall method. It aims to provide effective and continuous service as promptly as possible. Eventually, this is applicable with utmost collaboration removing any barriers between two parties. The benefits of such cooperation are fewer software fatalities and failures and less time consumption between fixes. DevOps is not easy to develop as it involves a lot of development, testing, and implementation of automated CI/ CD pipelines.

 

Importance of the CI/CD domain

Most people expand CI/CD as Continuous Integration and Continuous Delivery, respectively. These are two fundamental concepts required to develop DevOps. These two concepts are fundamentally basic tools and approaches as this make the development of DevOps different and unique from traditional methodologies. The conventional methods are time-consuming and outdated. In today's era where people have so little time, they require more advanced methodologies to save up their time and get the best quality service. They are required to do with one stage following up another, whereas DevOps gives the benefits of running these stages simultaneously within a short amount of time. In today's fast-paced era, it is a necessity than a luxury.

 

There are specific tools for DevOps engineers which are used to develop better applications and software. Following are some of the DevOps tools you need to know:

  1. Git and GitHub: These are required to manage source code. Git is a version control system required to manage your source code history, whereas GitHub is a cloud-based service to manage Git storage.
  2. Jenkins: It is an automation server used to build, test, and deploy software by developers worldwide. It assists in the formation of great CI/CD pipelines. Apart from Jenkins, Bamboo is another automation tool that is highly recommended for developers.
  3. Selenium: Selenium is an available tool used that automates web browsers and is mainly used for automation testing. It has a single interface that lets developers write test scripts programming like Java, C++, Python.
  4. Docker: With the help of Docker, developers can bring their applications and ideas to life by building, developing, and running applications. It is a Software Containerization Platform that allows developers to conquer the complexity of app development. Kubernetes is also such a containerization application.
  5. Ansible: It is one of the simplest automate used for configuration, management, deployment, and continuous service. For configuration management, there are other tools available, namely puppet Enterprise and Chef
  6. Nagios: These are referred to as monitoring software as it helps the developers to monitor and configure any issues and take immediate action to provide satisfactory results. Raygun is also another monitoring software that is used widely.
  7. Jira and Tello are two project management tools unique to DevOps, but it is worth using as it would help the developers keep track of their projects. They can use it to supervise the project's progress according to the deadline and identify any fatalities which can improve. There are more DevOps engineer tools, but these are some famous tools widely used by developers.

 

What is a DevOps Engineer?

A DevOps engineer is an IT professional who facilitates and processes automation throughout the software development cycle on CI/CD basis. They have to balance between coding to deployment and maintenance to upgrading. They understand and skill of various automation tools to develop digital pipelines, namely CI and CID pipelines.

Development teams and IT operation teams come together to bring out the best application with new features. Even if both these teams aim at the same goal, they both retain different skills. Developers are keen to add new features while the latter group thinks about preserving the application's stability. If the DevOps role is about amalgamation and combining processes, DevOps engineers are needed for automation, application management, and maintenance.
