Step-1: First, you must understand the DevOps definition. Most people confuse DevOps to be a tool or a technology. This is absolutely false. DevOps is a software development strategy that helps organizations to improve the performance, productivity, and efficiency of their products and services.

Step-2: Next, you must learn and become proficient with any programming language, like Python, Java, R, etc.

Step-3: Should be thorough with operating systems concepts, such as kernel management, memory management, I/O, threads, virtualization, containerization, DFS, etc.

Step-4: Followed by, you must learn how to configure your machine to automate your processes. Commonly used web servers include Nginx, Apache, and Tomcat.

Step-5: The next step is to learn Infrastructure as Code (IaC), which is used to manage resources through code rather than manual processes.

Step-6: Learning about CI/CD tools, like Git, Jenkins, etc.

Step-7: Learn how to monitor software using monitoring tools, like Nagios.

Step-8: You must understand the concepts of cloud computing by learning through some cloud tutorials, such as AWS, GCP, or Azure DevOps tutorials. 

• Without DevOps, the development team and the operations team would work in complete isolation, thereby affecting the productivity
• Manual code deployment could lead to human error in production. DevOps helps in automating the deployment process
• As online business is booming, most companies use software to improve the productivity of their business processes, where DevOps helps in automating these processes

There are numerous other reasons why DevOps matters in the software development process.

Yes, some DevOps services require coding. It depends on the tools you use for example:

• Shell Scripting for Jenkins job

• Ruby or Python for configuration management tools like Chef or Puppet

• Python

• Bash Scripting

• JavaScript

• Ruby

• Java

• Go

• SQL

• Scala

• PERL

Not mandatory but highly recommended. Python has a simple syntax with numerous libraries. As a result, the language is relatively easy to understand and has more flexibility and accessibility compared to many other programming languages.

In DevOps, Python is used for building cloud infrastructure projects, such as OpenStack. In addition, Python provides support for many web frameworks, like Django. 

Python helps in the implementation of CI/CD processes using several DevOps tools, such as Chef, Jenkins, Ansible, and Puppet.

The following are the skills needed for a DevOps professional :

Collaboration and Communication Skills

As DevOps bridges the gap between development and operations, communication and collaboration skills are highly essential for a DevOps engineer.

Familiarity with DevOps Tools 

A DevOps engineer must be familiar with the following skills:

• Planning strategies - Jira

• Version Control for coding - Git

• Building - Gradle, Maven, and Apache Ant

• Testing - JUnit

• Continuous Integration - Jenkins

• Configuration Management - Ansible, Chef, Puppet, etc.

• Containerization - Docker and Kubernetes

• Deployment - GoCD, AWS CodeDeploy, TravisCI

• Infrastructure as Code (IaC)

• Continuous Monitoring - Nagios, Splunk, etc.

Microservices

Microservices is an architectural approach, which helps in building and structuring an application as a collection of small services, facilitating faster and more efficient delivery of complex applications.

Programming Skills

One must be proficient in some programming languages, such as Python, Ruby, Java, JavaScript, SQL, Bash scripting, etc. They help in writing code and identifying and resolving bugs in the production environment.

Collaboration with QA Teams

A DevOps engineer must always be in touch with QA teams during the manual and automated testing processes. 

Continuous Learning

A DevOps engineer must build a growth mindset. They must integrate their learnings into the processes, constantly improve customer satisfaction, and promote innovation and market adaptability. Thus, DevOps is a journey having continual growth.
