Continuous integration and continuous delivery (CI/CD) are best practices for software development. Together, they provide a set of automated tasks to ensure the reliable deployment of software projects. (CI) is the practice of automating the integration of code changes from multiple contributors into a single software project. It’s a DevOps best practice, allowing developers to frequently merge code changes into a central repository where builds and tests run. Continuous integration (CD) is the automation of steps to facilitate changes into production safely. This focuses on the release and release strategy, while continuous deployment focuses on actual deployment. Continuous delivery This guide will focus specifically on the 15 every DevOps engineer should be familiar with today. Along the way, I’ll point to some of their distinguishing features and use cases, but if I missed one of your favorites, let me hear about it. Find or leave a comment below. continuous delivery tools me on Twitter Elements of a Good CD Tool Pretty much all the tools in this list will improve your development workflow. I think every good CD tool should be: CD automates a lot of manual processes that are often tedious and time-consuming. Time-saving. CD environments can save computing costs and can run tests across multiple OS and browsers. In general, a CD environment can accomplish more work than is practical on a developer's machine, making sure that the code is ready to be deployed Cost-saving. Solutions should be reliable 99% of the time or more. Anything below points to tooling or process issues. Reliable. Without further adieu, here are the top tools developers and DevOps professionals should know: 1. Travis CI Travis CI is one of the best CD tools for testing your code, verifying all the build steps, and making sure that your application is ready to be deployed. It’s also an excellent tool for CD beginners because of its quick setup time. It allows the user to sign up, link their repository, build, and test their apps, using plain files to configure pipelines. Its simplicity allows you to quickly get a sense of how all the stages of your deployment process are configured. yaml Travis CI integrates easily with common cloud repositories like GitHub and Bitbucket. Its server is hosted in the cloud, which cuts out the need for a dedicated server. Travis CI is free for open-source projects. For commercial projects, you need to purchase an enterprise plan. Features: Includes pre-installed database services Builds artifacts and checks code quality Offers visibility into tests while they’re running Creates a detailed delivery pipeline that is easy for newcomers and experienced engineers alike Includes support for multiple languages—Android, C, C#, C++, Java, JavaScript (with Node.js), Perl, PHP, Python, R, Ruby 2. Jenkins Jenkins is another popular CD tool, featuring a wide array of customization options. However, Jenkins isn’t the best choice for those new to CD. Jenkins’s popularity is due to the fact that it’s  open source and quite flexible. With Jenkins, you can easily automate your entire software delivery process on any platform. With hundreds of plugins available, Jenkins supports building, deploying, and automating for software development projects. Features: Provides a user-friendly interface Enables simple installation and upgrades across various operating systems Provides support to scale out to a large number of nodes, distributing the workload equally Supports the following languages—C, C++, Fortran, Java, PHP, and Python code, either directly or via automated build tools like Make or ANT Integrates with every tool in the CI and CD toolchain, thanks to hundreds of plugins available in the Update Center Allows you to do mostly anything you can think of, thanks to its extensive use of Groovy 3. GitHub Actions GitHub Actions is another accessible CD tool that’s highly beginner-friendly. If you have a GitHub account, you’re ready to start using GitHub Actions. GitHub Actions can perform all of the standard CD stuff (testing and QA, rollbacks, verification, etc.), but it goes one step further. GitHub Actions can automate your task outside of that context. For example, you can automate triaging, manage releases, and automate collaborations with your user base. GitHub Actions supports Node.js, Python, Java, Ruby, PHP, Go, Rust, .NET, and more. You can test and deploy applications in your language of choice. Features: Built into GitHub Offers multiple CD templates Enables multi-container testing Offers a great free plan Allows deployment of your application wherever you like Boasts a strong community 4. CircleCI CircleCI is a lightweight cloud-based continuous integration and delivery platform that automates testing and deployment processes. It supports Ruby on Rails, Sinatra, Node, Python, PHP, Java, and Clojure. CircleCI has an easily readable YAML configuration, is painless to set up, and doesn’t require a dedicated server to run. It’s suitable for small projects that need to get off the ground quickly. Linux plans start with the option to run one job without parallelism at no charge. Open-source projects get three additional containers for free. Features: Highly customizable Integrates with VCS tools Runs deployments using a container or virtual machine Splits and balances tests across multiple containers to reduce overall build time Supports the following languages—Java, Clojure, Elixir, PHP, JavaScript, and Python code Deploys to virtually any target and can be easily configured to integrate with other services 5. Bamboo Bamboo is one of the most popular CI tools on the market today. Written in Java, it’s used to build and test software projects, making it easier for developers to integrate changes in a project. It also aims to continuously deliver software by integrating a large number of testing and deployment software. Bamboo pricing tiers are based on agents rather than users. The more agents, the more processes it can run concurrently—either in the same build or different ones. Features: Offers hosted or on-premise versions Runs batches of tests in parallel, with quick feedback Facilitates real-time collaboration, including HipChat integration Suitable for any language, as well as technologies like AWS CodeDeploy, Docker, and Amazon S3 6. TeamCity TeamCity promises “powerful continuous integration out of the box.” But don't doubt their CD abilities. This promise speaks to what it offers beyond free tools like Jenkins: out of the box usability with excellent deployment history and source control integration. TeamCity runs in a Java environment, usually on an Apache Tomcat server, but it can be installed on Windows and Linux servers, too. It offers equal support for .NET and OpenStack projects, integrating into Visual Studio and IDEs like Eclipse. TeamCity is a commercial tool, with both free and proprietary licenses. Features: Easily customizes, interacts with, and extends the server Keeps the CD server functional and stable Boasts comprehensive VCS integration Supports Java, .NET, Ruby, and Python 7. GoCD If your focus is on continuous delivery, you should be using GoCD. A solid Jenkins alternative, GoCD is suitable for anyone building deployment pipelines, no matter your experience level. Unsurprisingly, GoCD was built on the principles of . It’s free and open source. continuous delivery Features: Enjoys active community for help and support Boasts secure deployment to production Allows deployment of your application wherever you like 8. GitLab CI/CD is the newest choice when it comes to CI/CD tools. Built into GitLab, it’s a free CI/CD tool that can be self-hosted.
