DevOps fundamentals: Defining DevOps principles

From headlines to job descriptions, DevOps has emerged as an outsized buzzword over the past decade—and for good reason. Organizations that successfully adopt DevOps often see big gains in software development speeds, improved reliability, faster product iterations, and have an easier time scaling their services.

The fundamentals of continuous integration in DevOps

What is continuous integration in DevOps? Continuous integration (CI) is a foundational DevOps practice where development teams integrate code changes from multiple contributors into a shared repository. Automation is used throughout this process to merge, build, and test code to facilitate a higher speed of software development. This process is often called a CI pipeline. When implemented properly, CI enables organizations to quickly identify defects and ship higher-quality software faster.

A guide to DevOps tools and DevOps automation toolchains

What are DevOps tools? As an umbrella term, DevOps tools include any number of applications that automate processes within the software development lifecycle (SDLC), improve organizational collaboration, and implement monitoring and alerts. Organizations will often invest in building out a "DevOps toolchain," or collection of tools to use in its DevOps practice, to address each stage of the SDLC.

What is containerization?

When it’s successfully implemented, DevOps can transform software reliability by making the software development lifecycle (SDLC) more predictable through a combination of automation and cultural practices that favor deep collaboration and incremental releases. With less chance for variation, fewer code-related issues make it to production.

The fundamentals of continuous deployment in DevOps

What is continuous deployment? Continuous deployment (CD) is an automated software release practice where code changes are deployed to different stages as they pass predefined tests. The goal of CD is to facilitate faster releases by using automation to help remove the need for human intervention as much as possible during the deployment process.

DevSecOps explained

DevSecOps builds on the ideas of DevOps by applying security practices throughout the software development lifecycle to ship more secure code faster.

Should we think of DevOps as a methodology?

There’s one word that perfectly describes successful DevOps: flow. As individuals, we experience a state of flow when everything in our work comes together naturally and at the right time. DevOps enables that kind of flow at the organizational level through a combination of tooling, culture, and process.

What is a DevOps pipeline? A complete guide

A DevOps pipeline combines processes, tooling, and automation to enable organizations and software teams to build, test, and deliver high-quality software quickly to end users.

What is the DevOps Model? Exploring foundational practices in DevOps

DevOps helps teams ship high-quality products faster by reducing the friction between writing, testing, and deploying code. GitHub offers a holistic platform designed to help organizations successfully adopt DevOps, making it easier to continuously ship and improve software.
