Hey, amazing readers!

Welcome to the simplified series in which I am going to explain complex tech in simple terms with a brief explanation. This is the first chapter of the series in which we will explore DevOps. We will learn about the use, why to know and what actually it is? This article definitely helps to understand DevOps concepts, a resource to learn, and how to jump into the DevOps world. Let's get started with the introduction!

Introduction

Let's try to understand DevOps need, and why we actually need it. It combines development (Dev) and operations (Ops). The primary goal of the DevOps engineer is to manage and secure applications and increase development speed, and efficiency, and build & deploy secure software applications.

DevOps engineer works with both the development and operation teams and manages the flow of the core operations. Let's simplify DevOps need in a single term,

If you want to build better software faster, DevOps is the answer!

Why DevOps

The aim of DevOps is to integrate the work of the software development and software operation teams by providing a culture of collaboration and shared responsibility.
The process of developing software applications is to people works together to develop a better and more secure application with a number of operations there to execute which is not easy to handle and disturbs the flow of the program, and here DevOps take place to help with development and operations that's why we need DevOps.

The software industry regularly updates and businesses transforms from entertainment to shopping to buying digital assets. Software is an integral component of businesses and secure & direct interaction is possible through software.

The software development also increases the complex operations and where we need DevOps!

DevOps lifecycle

The DevOps lifecycle consists of ten stages that execute from the beginning of the development process to delivery and maintenance!

1. Manage

DevOps closes the loop and incorporates feedback and learnings from the entire lifecycle into your ongoing iteration.

2. Plan

DevOps describes the work that needs to be done, prioritizes it, and tracks its completion. Package DevOps stores the software in a state where it can be reused later.

3. Create

DevOps writes code, proposes changes, and discusses these proposals with coworkers.

4. Verify

DevOps automatically tests code to make sure it works correctly.

5. Package

DevOps stores the software in a state where it can be reused later.

6. Secure

DevOps checks whether the software contains vulnerabilities through static and dynamic tests, fuzz testing, and dependency scanning.

7. Release

DevOps deploys the software to end users.

8. Configure

DevOps manages infrastructure and software platforms.

9. Monitor

DevOps sees the impact of the software is on infrastructure and users. It also provides data to help effectively respond to incidents.

10. Protect

DevOps secures the infrastructure the software is running on by ensuring containers are up to date and locked down.

What is DevOps Engineer

The one who follows all aspects DevOps lifecycle from beginning to the end including all operations and development processes. The DevOps engineer also handles critical information and customer communication. Apply automation where it's possible, test and analyze the code and build & deploy the necessary modules.

The DevOps engineer requires knowledge of a different range of programming languages and communication, collaborations lead you to become a better DevOps engineer.
