Get to Know DevOps: Everything You Need to Know

INTRODUCTION

You may have heard about DevOps changing the IT industry, but what does that really mean? If you’re looking to break into the field, you need to know what you’re getting into before you start your career in this fast-paced and constantly changing environment. This guide on DevOps breaks down the basics, so you can see if it’s something you want to pursue or not.


The definition

DevOps is a software development process that unites the work of developers and IT professionals to shorten the time between a code commit and application deployment. In this guide, we're going to break down what DevOps is, why it's important for your company, and how you can start implementing it in your own business. We'll also give you tips on where to go for more information and inspiration, as well as some common pitfalls that could hold you back. If you're ready to join the revolution, then read on! DevOps has been around for about 10 years now, but it has only recently started becoming mainstream. The number of jobs related to it has risen dramatically over the past few years, and so have salaries - up by as much as $50K from an average developer salary in 2013. With all that said, most companies don't know where to begin when looking into DevOps or which aspects will benefit them most.


The benefits

Here are a few of the benefits that come with adopting DevOps in your organization.
- Better customer satisfaction as you can provide better, faster, and more reliable services.
- Increased operational efficiency as you're able to get more done with less resources.
- Reduced costs as you're able to cut back on waste, increase efficiency, and utilize your staff more efficiently. - Increased agility as you'll be able to work through new processes and technologies more quickly without fear of failure.
- Reduced time to market for new products or services by taking advantage of quick feedback loops from customers about what they need.


The characteristics

DevOps is a software development method that emphasizes communication, collaboration and integration between software developers and IT operations professionals. It targets laying out a culture where building, testing, and releasing software can happen rapidly, frequently, and all the more dependably. The overall goal of DevOps is continuous improvement in the entire process from idea to production. The following are some of the key features of this methodology: The goal of DevOps is continual improvement in the whole process from idea to production. It seeks better alignment among developers, IT operations staff and business owners; it also facilitates rapid response times when changes are requested or problems arise because there is no barrier separating development, operation and support teams.


How it started?

The DevOps movement can be traced back to 2007 when Patrick Dubois and John Willis published the Agile System Administration Manifesto. The manifesto called for systems administrators to take on more of a software engineering role, working with developers and engineers throughout the development process. They wanted to eliminate the traditional separation between infrastructure team members and software developers in order to better integrate their workflows. Along with this, they proposed that organizations should automate as much as possible because it would result in higher-quality releases while also increasing productivity.


What are the tools involved?

Tools are an essential aspect of DevOps. While there is not a one size fits all solution, the more tools you have at your disposal, the better. For example, if you are using Chef for configuration management and Vagrant for development environments, then Ansible can be used as a module that allows you to automate application deployment in your production environment. A suite of testing tools like Cucumber, RSpec and Behat will make sure your code doesn't break in unexpected ways.
A tool like Jenkins will let you continuously deploy new versions of your code so it can stay up-to-date with any changes made upstream.
There are many options out there and knowing which one best fits the needs of your organization is important.

What is its role in Agile software development?

DevOps is the term used to describe an organizational culture that emphasizes communication, collaboration, and integration between software developers and IT operations professionals. In an agile software development process, the goal of this culture is for both groups to work together as equals. When IT operations professionals are given more decision-making power about what’s in their systems and how they want them configured, they can give feedback on what’s being developed. And when the people who develop a system have a say in its deployment, they're able to suggest ways to make it easier or less disruptive when it's put into production. With better communications across these two groups, there's a greater likelihood that problems will be detected earlier and fixed faster.


How do we adopt it?

DevOps is a relatively new term that has been gaining more and more attention in recent years. The goal of DevOps is to create an environment where developers and IT operators can work together seamlessly. It's a philosophy that emphasizes communication, collaboration, integration and automation. To adopt the practice, you should first identify the steps involved with your current software delivery process and how long it takes for each step. Next, identify areas for improvement in your process or pain points where delays can be reduced or eliminated. Then, break down these improvements into small pieces of work to start working on. Smaller chunks of work are easier to tackle and are less intimidating than one large project. Focus on what is most important for your business first before moving on to other areas that need improvement.
