When I started my career as a software developer, I often used to think about the need to have green builds for pushing a single line of code. But, with time, I realized the importance of having green pipelines and overall the value of [DevOps culture](https://www.lambdatest.com/blog/how-to-keep-ceos-deeply-invested-in-devops/?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=blog). In layman’s language, one can say, “DevOps is the go-to solution in case you want to work collaboratively without any hustle!”

Read this blog on getting started with DevOps to explore all the aspects of your DevOps journey from scratch. Even if you get your hands dirty with DevOps tools every day, you might want to read this DevOps tutorial to acquaint yourself with the latest tools and practices.

## What is DevOps?

DevOps is a culture that acts as an enabler of agility. It bridges the gap between the developers and the maintainers by implementing practices of collective responsibility. Traditionally, these teams had a barrier between them, and software packages were metaphorically thrown past the wall. But, with DevOps processes, that barrier is no longer in existence.

![](https://cdn-images-1.medium.com/max/2000/0*dBYo3FtVaUQ7Ydcw.png)

Collaboration is one of the guiding pillars of DevOps, which eventually results in faster deployments. In DevOps culture, teams come together and share responsibilities of streamlined builds catalyzed by continuous deployments, automation, and production infrastructure. A cross-functional team improves engagement and communication over traditional silos of perpetual disagreement and time-consuming ticketing processes.

Nowadays, the term DevSecOps is also a buzzword. This flavor of DevOps culture involves maintaining the security compliance of the software right from the project initiation phase till its delivery.

However, in this blog on getting started with DevOps, we will only deal with “DevOps” and explore how to get started with it.

## The Contrast: Before DevOps vs After DevOps

Before DevOps came into the picture, software companies followed the traditional ‘[Waterfall’ model](https://www.lambdatest.com/blog/agile-vs-waterfall-methodology/?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=blog) that worked well for many projects like CRM, inventory management, etc. Yet it has its own set of drawbacks. However, when DevOps came into the picture, it completely changed the software development concept.

![](https://cdn-images-1.medium.com/max/2000/0*csHBh_H8kTUvtNuf.png)

This short comparison is enough to let you know why the ‘Waterfall model’ is the thing of the past and why ‘DevOps culture’ is the way forward:

## Knowing Basics of Terminal and Shell Scripting

Getting comfortable with terminal commands is a prerequisite to being a DevOps engineer. Practicing these commands daily for process monitoring and manipulation of system performance polishes your scripting skills.

Terminal lets you accomplish different tasks without the use of a Graphical User Interface (GUI). It is also known as console or command line.

Below are some of the basic shell scripting functions to learn to get started with DevOps:

* Text Manipulation

* Compilation

* Bash or Shell Scripting

* System Performance

* Powershell/VIM, etc.

## Understanding Networking Concepts

When running an interconnected system of servers, apps, and resources on a network, it is crucial to learn about the networking and security concepts to diagnose any troubleshooting issues or network issues.

A few of the networking concepts that you must get familiar with are stated below:

* TCP/IP network protocols

* HTTP and HTTPS

* SMTP and FTP

* SSL/TLS

* Network Forwarding

* Firewall and Proxy

Understanding networking allows you to create an environment where you can test your functions and put continuous integration and delivery pipelines in place. Let’s explore the continuous integration and deployment concept in the next section of this article on getting started with DevOps.

## Continuous Integration & Continuous Deployment

The main keywords associated with DevOps are **Continuous Integration (CI)** and **Continuous Deployment (CD)**. It is a norm to implement these practices to adopt the DevOps culture. Without these, DevOps is incomplete!

As per Statista, 62% of organizations at a more advanced stage of their DevOps evolution have adopted Continuous Integration and Continuous Delivery (CI/CD) to meet organizational needs while they continue to adopt self-service capabilities.

![](https://cdn-images-1.medium.com/max/2150/0*cTWPtCzv-BMB87dD.png)

This aspect of DevOps helps to make frequent stable deliveries while maintaining the code quality. A **Continuous Integration** pipeline often runs on the feature and master branches of a code repository. It ensures that your bits of code produce no error when integrated into the shared master repository.

A **Continuous Deployment** pipeline runs automation tests on the code for a particular release scope. This helps with reducing costs, [accelerates delivery timelines](https://www.lambdatest.com/webinar/how-does-enterprise-accelerate-test-and-release-velocity?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=webinar), and reduces effort. It also helps to enhance the overall efficiency and team productivity.

Cloud technologies provide better flexibility, dynamic configurations, controlling web servers and databases, etc. Cloud deployment ensures that you need not rewrite configuration files, and scaling up and down the servers takes place dynamically. Softwares like Nginx can help you manage your servers more efficiently.

Furthermore, several relevant standardized DevOps certifications are available online to help kick off your career as a DevOps Engineer. DevOps Certifications not only enhance your knowledge but also validates your skills in a particular domain that is beneficial for moving ahead in your career graph.

## Key Factors to consider before Getting Started with DevOps

The demand for DevOps is always at an all-time high in the IT industry. Hence, it is necessary to understand what DevOps is and, more importantly, what it is not. Organizations often struggle to implement collaboration, agility, and orchestration in their attempt for DevOps evolution.

Therefore, to utilize the metrics-based results that DevOps tools and technologies offer, the organization must be willing to adopt a few incremental changes as mentioned below over the years.

## Technological Automation

Learning about automation is an important part of DevOps. The ability to automate hefty processes of managing servers and deployments is something that recruiters look for in an ideal DevOps candidate.

[Automation certifications](https://www.lambdatest.com/certifications/?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=certification) and courses may help to understand the details of automating processes. The approach should be to automate anything you perform manually more than two times. The [CI/CD best practices](https://www.lambdatest.com/blog/16-best-practices-of-ci-cd-pipeline-to-speed-test-automation/?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=blog) and everything-as-code helps you and your organization adopt the DevOps culture better. You can learn more about it by going through these articles on the importance of [automation testing in DevOps](https://www.lambdatest.com/infographics/importance-of-automation-testing-in-devops?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=webpage) and the role of [automation testing in the CI/CD pipeline](https://www.lambdatest.com/blog/automation-testing-in-ci-cd-pipeline/?utm_source=devto&utm_medium=organic&utm_campaign=nov23_sd&utm_term=sd&utm_content=blog).

## Processes and Practices

The main purpose of DevOps is to regularly deliver small incremental value products or services to the customer. To achieve this feat, one must comply with the chief practices of DevOps — Continuous Integration (CI) and Continuous Deployment (CD). These small units of incremental delivery are also operationally supported in the production phase.

## Shift to DevOps Culture

DevOps is not simply a project that has a definite deadline. Instead, DevOps is a culture that comes with major organizational and technological changes. DevOps teams break down silos by having cross-functional teams and reducing hand-offs, handovers, ticket queuing systems, and dependency mapping. DevOps is a movement or culture shift in application or software development.

The goal of DevOps is to make everyone accountable and work together with full responsibility to break silos or resolve bottlenecks in the whole process and not just the developers.

## Best Practices of a DevOps Champion

While the organization should adopt the DevOps culture and practices and be collaborative, everyone in the team need not be an expert in the DevOps technologies. Companies such as Google, Amazon, Microsoft, Salesforce, RedHat, etc., are constantly hunting for experienced or senior DevOps engineers, often known as DevOps Champions, who would drive the team’s success by implementing DevOps in the correct order!

However, DevOps adoption is not the responsibility of a single person in the team. Instead, it is the job of the whole organization to embrace DevOps as a culture and part of their daily work. Collaboration, communication, and cross-functional approach help you get started with the DevOps mindset of “constant improvement”. Once implemented across teams, DevOps can help you break silos and only focus on delivering value MVP (Minimal Viable Product).

As a DevOps Champion, you will serve as a technical expert on solutions and a voice and champion for users, prospects, and partners, driving feedback to engineers and product management.

Below are some of the characteristics of a DevOps Champion that are usually expected in the IT industry to help the team embrace the culture shift to DevOps.
