DevOps Tutorial For Beginners: Learn DevOps From Scratch

Introduction

The DevOps market is booming, expected to reach $12 billion by 2026 according to industry analysts. Surveys show near-unanimous agreement (99%) on its positive impact within organizations. This rapid growth reflects a fundamental shift: businesses today are essentially software businesses. In this environment, DevOps and Business Analysts have become critical disciplines.

Why DevOps?

Traditionally, development and operations teams worked in silos, leading to slow and inefficient software delivery. DevOps bridges this gap by fostering collaboration and automation. This improves the speed and quality of applications reaching customers.

What You'll Learn in This DevOps Tutorial

This beginner-friendly tutorial dives deep into the world of DevOps. You'll gain a solid understanding of:

• DevOps fundamentals: What it is, its origins, and how it differs from traditional IT.
• The need for DevOps: Why it's crucial for businesses today.
• Key DevOps features: Continuous development and deployment, configuration management automation, inter-team collaboration, and IT service agility.
• DevOps lifecycle and workflow: How DevOps teams work together.
• Top DevOps job roles: In-demand skills for a successful DevOps career.

By mastering these areas, you'll be well-equipped to contribute to a culture of continuous improvement and efficient software delivery.

What is DevOps?

DevOps word in itself is a combination of two words one is “Development,” and the other is “Operations.” It is neither an application nor a tool; instead, it is just a culture that collaboratively promotes development and operation. As a result of DevOps implementation, the speed to deliver applications and services has increased.

DevOps enables organizations to serve their customers powerfully and better in the market. In other words, we can say that DevOps is the process of alignment of IT and development operations with better and improved communication.

Where did DevOps come from?

There are many stories about the DevOps origins, but it is not created out of the whole cloth. Its seeds were planted many years ago and recently nurtured by expert IT professionals in several disciplines. Two primary ancestors of DevOps are given below:

1. ESM (Enterprise Systems Management): People involved in the initial phases of DevOps are system administrators. These experts brought the critical ESM practices to DevOps like configuration management, automated provisioning, system monitoring, the toolchain approach, etc.
2. Agile Development: DevOps can be considered as an outgrowth of agile. It is simply extending the Agile principles beyond the boundaries of the code to the entire delivered services.

What is the need for DevOps?

DevOps implementation has increased the rate of software delivery and revenue for business stakeholders. The following listed reasons are the most considerable ones that led to the creation of DevOps.

• Before DevOps, operation and development teams worked in an isolated environment.
• Testing and Deployment activities were primarily performed, isolated after the design-build step, which took more time than the actual project completion time.
• Team members usually spend a significant amount of time in deploying, testing, designing, and building the projects
• Human production errors were deployed during manual code conduction.
• Operations and coding teams generally had different timelines and did not have proper synchronization, which resulted in further delay.

To avoid the hassles mentioned above and non-collaborative performance measures, there was an urgent need for robust IT technology like DevOps to satisfy business owners and stakeholders.

How is DevOps different from Traditional IT?

Let us compare the waterfall model with DevOps to see what changes DevOps brings to IT. Take a few assumptions for this comparison, like the application has to make live in the next two weeks, and more than 80% of the coding is complete. We assume that the application has been launched recently, and the process of buying servers to ship the code has just begun.

7 Signs that Show You Need DevOps

Developers and Operations engineers are two different organizational teams. If these teams are found to be on the wrong track, it signifies that you need to know DevOps practices for perfect results. We have consolidated here seven signs that can help you answer whether you need DevOps or not:

•  The development team cannot detect software defects at the early age of its development.
• Agile methods are used to speed up the software development process, but as soon as the application goes to the production department, all methods become ineffective.
• Testing and development team members cannot access resources timely, so the development process is delayed.
• You are not able to identify the exact problems of the development, testing, and production department
• Simple human errors are often creating hurdles during the development and deployment process.
• Once the app is in production, developers think that their job is over.
• At the time of the problem, both development and operation teams start blaming each other.

What are the Features of DevOps Implementation?

The DevOps offer continuous integration and continuous delivery. It makes the product delivery cycle quicker, and enterprises can launch the software on time without compromising its quality.

Following are the factors that will improve as a result of DevOps implementation:

• Predictability: DevOps decreases the failure rate of new product releases.
• Maintainability: The process improves the overall recovery rate at the time of the release event.
• Improved Quality: DevOps improves product development quality by incorporating infrastructure issues.
• Lower Risk: Security aspects are incorporated in DevOps SDLC, and the number of defects gets decreased across the product
• Cost Efficient: Cost efficiency is improved due to DevOps, which is always an aspiration of every business organization.
• Stability: DevOps implementation offers a stable and secure operational state.
• Streamlined Delivery Process: As DevOps provides streamlined software delivery, the marketing effort is reduced up to 50%. It happens due to mobile applications and digital platforms.

“DevOps is truly not just the unicorns of big IT hubs like Amazon, Google, Facebook, etc., but it can be adopted by almost any organization today instead of their sizes.

DevOps Lifecycle Phases and Measures

DevOps is basically an integration of development and operation processes. One cannot implement DevOps without understanding its lifecycle. The following steps are included in the DevOps lifecycle:

Workflow in DevOps

Workflows shows a visual overview of sequences in which inputs are provided. It tells you about actions and outputs that are generated based on operational processes. It can arrange and search for jobs that users frequently request. It gives you the ability to mirror the ideal processes in configuration jobs.

DevOps Workflow:

• Parallel job execution
• Sequential Job execution
• Brach-level filtering

How DevOps Improved the Development and Operation Process?

DevOps solves development challenges in the following ways:

• Code deployment time is reduced because of the faster testing process and speedy feedback mechanism.
• Developers do not feel work pressure and can build new code in less time.

As far as operation process execution is concerned, the implementation of DevOps improves the operational processes in the following ways:

• Configuration management helps the organization to execute and organize the configuration plans, and they become able to manage their infrastructure in an effective way.
• Containers and virtualization concepts provide a simulated environment to increase software reliability and maintain the uptime of the production environment.
• Effective and improved server monitoring is offered. As a result of this, proper feedback can be provided, and effective administration is assured.
