Have you ever wondered how leading tech companies can deliver new software quickly, reliably, and often with fewer bugs? The secret is DevOps, a modern software development approach that brings together development and operations. If you're a student, IT professional, or novice engineer, this beginner’s guide will introduce you to DevOps and how to get started in this rapidly growing career.

What is DevOps?

DevOps is a software development approach focused on collaboration, automation, and continuous delivery to deliver an ongoing flow of high-quality products to customers quickly and efficiently. DevOps breaks down the traditional silos between development teams and operations teams, in a way that ultimately promotes communication and trust for faster time-to-market and improved customer collaboration and satisfaction.

DevOps allows a team to work through an entire application lifecycle, starting from development and going through testing, operational support, quality assurance, release management, and continuing through production and deployment stages. It illustrates a collaboration between development and operations teams, allowing teams to deliver code into production frequently, in an automatic and repeatable way.

In DevOps, automation exists in every phase of the software development lifecycle, from planning, coding, testing, deployment, and monitoring. This increases productivity, ensures consistency, and reduces errors. DevOps establishes a culture of continuous improvement by redefining the processes to include feedback loops, allowing the team to iterate faster and make more informed decisions. By embracing DevOps, the organization can become more agile, reduce costs, and innovate faster.

Why DevOps Matters

DevOps is important because it reshapes the process of software development, testing, delivery, and upkeep. These transformations are valuable to organizations because they can see faster releases, better quality, and more effective collaboration and communication between teams that have traditionally functioned in silos. In the modern era of digital transformation, customers expect continual updates to their software, constant uptime and high reliability, and a way to quickly fix any bugs that might arise. DevOps responds to these expectations by facilitating people, processes, and technology automation that embraces a collaborative culture and many feedback loops that enable a continuous development lifecycle.

By maximizing collaboration and breaking away from separating the development team from the operations team, DevOps reduces the number of mistakes, minimizes time to deliver a solution, and improves the stability of any software product. DevOps gives teams the ability to pivot rapidly based on user feedback or changes in the business climate, which provides organizations with competitive advantages. The important takeaway is that DevOps is not just tools - it is ultimately a change in perception of how teams identify processes to deliver value to users.

Understanding DevOps Principles

DevOps has a foundation of principles, which will help teams to develop, deliver, and maintain software more efficiently. The principles improve collaboration, automation, reliability, and speed for all areas in the software lifecycle. Knowing the principles of DevOps is important for anyone who is looking to adopt or work in a DevOps environment.

1. Collaboration and Communication

DevOps is all about breaking down barriers between Development, Operations, QA, etc., and creating a shared responsibility culture with an emphasis on communication as a team to allow for easier issue resolution and working towards mutual goals.

2. Automation

Automation is one of the key principles of DevOps. It removes or limits manual tasks in processes like code testing, integrations, deployments, and provisioning changes in the infrastructure, leading to quicker, more uniform results.

3. Continuous Integration and Continuous Delivery (CI/CD)

Continuous integration helps ensure that code changes are automatically tested, the code is integrated into the main codebase, and that deliverables to production environments are automated and timely. It allows teams to find bugs sooner and deliver features faster.

4. Infrastructure as Code (IaC)

Infrastructure as code consists of managing and provisioning infrastructure through code instead of through manual or physical processes. It allows for easier consistency with environments, scalability, and allows for replication.

5. Monitoring and Feedback

In DevOps, we continuously monitor our applications and infrastructure based on pre-determined metrics. This helps the DevOps team identify issues in real-time. The team uses this feedback to gain insights while working on product development to improve performance, fix bugs, and guide the direction of the product development.

6. Lean and Agile Mindset

DevOps strives to utilize Agile practices and Lean principles to create an approach that focuses on continuous development, customer feedback, and rapid iterations, such as product development, which allows teams and individuals to remain nimble while responding to the inevitable changes and challenges.

Who Should Learn DevOps?

DevOps is beneficial to anyone who participates in the software development lifecycle. More specifically, anyone who wants to improve a process, improve collaboration, and/or speed things up. The main target audiences for learning DevOps include the following:

1. Software Developers

Developers benefit from the knowledge of how deployment processes work, infrastructure, and learning to automate things, which all reduce the friction of delivering and maintain their code in production.

2. System Administrators / IT Operations

As systems administrators learn DevOps, they can now learn to automate their infrastructure, leverage tools like Docker and Kubernetes, and work collaboratively with development teams.

3. QA/Test Engineers

DevOps gives testers the ability to work in CI/CD pipelines, automate testing, and be a part of the QA paradigm shift to faster and more reliable releases.

4. Release Engineers / Build Engineers

As release engineers and build engineers learn to use automation tools, version control, and develop with containerization, they will benefit from an increase in efficiency in their build and deployment processes.

5. Security Professionals (DevSecOps)

Many of the security teams that work with DevOps have been able to move security processes earlier in the development process, meaning they are able to identify vulnerabilities sooner - not to mention that automating security still means they are able to speed up the development process.

6. New IT Professionals or Students

If you are new to IT, learning about DevOps will give you a competitive advantage and provide opportunities in cloud platforms, automation technologies, and new development environments.
