Software is evolving very rapidly and the consumer number as well. Various software architecture patterns are being use by the companies because they are reliable. So, adopting such skills have high demand in the market. Many full-stack developers know how to build and deploy software on cloud to make it available for everyone. In this blog, we will be going through the journey of how to become a devops engineer.
Who is a DevOps Engineer?
A person who knows how to deploy software on cloud servers and make them available to the public. This is the simplest definition one can read. DevOps engineers feel the gap between developers and the operations team. It must require expertise in domains like development, automation, and cloud technologies.
Let’s take a look at the roles and responsibilities.
Roles & Responsibilities
Day to day job of a DevOps engineer involves various tasks related to the infrastructure. They design and automate repetitive tasks of the organizations. Here is the detailed list of the tasks:
1. Writing Scripts
Many of the task require manual interactions to execute or perform activity. Those kinds of activities can be automated by writing scripts in Python or bash. So, once we execute the script it will do all the activity as per the script.
For example, some projects might require environment setup, cleaning the cache, or starting up the databases. so such tasks can be easily automated via script.
2. Optimize Performance of apps
It is one of the most required skills to become a DevOps engineer. This skill directly impacts the cost of your infrastructure. This means If you increase the performance of the application, then it will reduce the cost required to run infrastructure. DevOps engineers should be able to identify the key areas to work on and optimize them on time. This skill will make you different from other engineers.
3. Setting up CI/CD Pipelines
Nowadays, companies mostly use agile development methods to release their software. It is one of the best methods used for software development. Continuous Integration and Continuous Deployment are the main features of the agile method. So, the DevOps engineer needs to setup CI/CD pipelines to automatically perform this task. For this knowledge of various tools is required. For example, Jenkins, AWS Codepipeline, etc.
Basics of DevOps
The basics of DevOps include various tools and technologies. It is about collaboration, automation, and iterative development. Below is the list of tools and technologies you need to know before starting this journey.
Tools

Programming Knowledge Is Required
During your journey, you will be handling literally every type of application. And you must know how specific frameworks or languages work and the changes to be done. At baseline, you should know Bash, Python, Go, etc.
Build beginner-level projects and deploy them on infra. It will help you to understand what the necessary changes required to make a particular app live. With experience, you will find out various ways to deploy the same application.
Knowledge of Cloud Providers
Most of the companies use mainly 3 cloud providers namely Amazon Web Service, Azure, and Google Cloud Provider. A good understanding of such providers will help you to land a good job.
Most of these services are easy to use and scalable. One must know how this cloud works internally and connect with each other. Sometimes you might be working on distributed systems which are mainly deployed on a hybrid cloud. So learning these main cloud providers is very important.
They provide certifications as well. Those certifications will help you land a good job. People will recognize you knowing that you an experience and knowledge in DevOps.
