8 Best CI/CD Tools to Build a Solid Software Delivery Pipeline

Organizations increasingly rely on DevOps to streamline business processes in the software-dense world. Meanwhile, their success with DevOps, in turn, can be attributed to the principles of continuous integration and continuous delivery. And the reason is – the best CI/CD tools efficiently use the power of automation to create a streamlined software delivery pipeline.

CI/CD introduces continuous monitoring and continuous testing throughout the lifecycle of applications. So choosing a proper tool is essential, whether it’s reducing the complexity of tasks in continuous delivery pipelines, building automation in workflows, or efficiently managing code changes and bugs.

This article presents a highly-recommended CI/CD tools list for establishing a smoother path to production and increasing the speed of innovation.

Simform is a leading CI/CD implementation and management company, helping businesses have a scalable, secure, and cost-effective CI/CD pipeline. Contact us today to have bespoke CI/CD services for projects of any scale.

Let’s first get hold of what these tools are that reduce manual errors and improve feedback loops throughout the SDLC.

What are CI/CD tools?

By supporting a marketplace of plugins, CI/CD tools provide various functionalities for automating the stages of app development and enable developers to release high-quality, error-free code regularly. These tools perform many tasks, like they –

  • Let development teams set environment variables, mask variables like account keys and passwords, and configure them again while deploying on the target environment.
  • Automate testing for reviewing and validation of the software
  • Create a document trail of the software development process.
  • Avoids integration issues by promptly discovering errors caused by frequent source code modifications.
  • Provide dashboard and reporting functions to implement observable CI/CD pipeline.
  • Alert the developers if a build or delivery fails.

Everyone working in the software industry realizes the never-ending demand for evolution at some stage. That’s why the modern software development lifecycle emphasizes the automation of the CI/CD process. And when there is automation, there are tools!

Although there was a time when one particular tool solely ruled the tools spectrum (we’ll soon talk about this tool that’s still popular!), many new contenders have emerged with out-of-the-box features. Therefore, it’s natural to wonder what is the best CI/CD tool.

However, before diving deep into these tools, let’s wind back the clock a little!? Thanks to the agile manifesto, technological practitioners realized the need for “continuous improvement.” As a result, the term CI/CD gained momentum in the 2000s with the emergence of Java, Javascript, and PHP. And entered the predecessor of continuous integration tools, Jenkins!

Jenkins: De facto CI/CD tool

Built on the Java Virtual Machine (JVM), Jenkins is an open-source, most widely deployed automation server. Formerly known as Hudson(2004 onwards), the first Jenkins version was released in 2011. Jenkins integrates and automates each phase, each process of SDLC, including build, document, package, stage, deploy, test, static analysis, and more.

Key features of Jenkins

  • Being platform-agnostic, Jenkins is compatible with Windows, Linux operating system, and Mac OS and runs on ports 8080 and 8443.
  • The easy installation process as a self-contained Java program; and configuration of Jenkins can be carried out using a web interface that contains on-the-fly error checks and built-in help.
  • Plugin architecture provides nearly endless possibilities for what Jenkins can do, making it quite extensible.
  • Numerous plugins for integration with different test automation tools for the test pipeline
  • Jenkins can also be integrated with major cloud platforms like Google Cloud, Amazon EC2, Atlassian Cloud, VMWare vSphere, etc., using plugins.
  • Easy work distribution across multiple machines ensures faster builds, tests, and deployments across multiple platforms.

One of our clients came up with the brilliant idea of building a white label software that would help auction houses go digital. Simform built a scalable, secure, and cost-effective CI/CD pipeline with Github, Terraform, AWS Lambda, Docker, and Kubernetes. However, Jenkins was the rockstar of this pipeline and was used for integration, delivery, and deployment automation. Ultimately, our client achieved 500 weekly commits in less than 2 months.

USP:

Its vibrant, active community offers more than 1800 plugins to let Jenkins integrate with virtually any tool, including every best-of-breed solution used throughout the continuous delivery process. For instance, Git, Amazon EC2, Maven 2 project, HTML publisher, etc.

Who uses Jenkins?

Facebook, Netflix, LinkedIn, Instacart, Robinhood, Twitch, Udemy

Pricing: MIT License, free tool; however, users must pay for the hosting server.

CircleCI: Automate confidence in your code

As one of the most used DevOps tools, CircleCI processes more than 1 million builds a day. Founded in 2011, CircleCI is a CI/CD automation platform that enables rapid code release and automates the build, test, and deployment. Despite being a paid solution, CircleCI allows open-source projects to access up to 30,000 free credits per month. This flexible CI tool runs in any environment like a Python API server, cross-platform mobile app, or Docker cluster.

Key features of CircleCI

  • Integration with GitHub, Bitbucket, and GitHub Enterprise to create builds when new code lines are committed.

Factors to consider before selecting CI/CD tools

Different industry verticals like media and entertainment, retail, eCommerce, healthcare, etc., are increasingly adopting CI/CD best practices to make the deployment easy. Consequently, the continuous integration and continuous delivery tools market is projected to reach ~US$ 19 Bn by 2031.

However, every organization will have particular continuous delivery needs at the end of the day. So, here are some suggestions to keep in mind while selecting deployment tools for CI/CD.

  • The tool should be easy to install and configure to save your time, effort, and investment.
  • If your organization executes DevOps processes on-premise, you should look for the vendors that provide tailored installation services for your organization-specific use cases.
  • Check if your desired software development tool is aimed at business users (with a low-code or codeless automation platform) or is developer-centric.
  • As collaboration is essential for DevOps success, the CI/CD solution should be able to facilitate continuous coordination and communication between development and operations teams.
  • The preferred CI/CD tool should integrate with your existing tech stack, including software development tools and production environments.
  • The tool should be capable of handling complex digital environments and allow different stakeholders across the organization to use the tool meaningfully.
  • It is essential to select a CI tool that offers support for your project’s version control system.
  • As a modern software development trend, containerization technology has become almost indispensable, so your CI/CD automation tool must offer support for integrating containers into the CI/CD workflows.

Automation and CI/CD go hand-in-hand
