Jenkins vs Zuul CI: What are the differences?

Key Differences between Jenkins and Zuul CI

Jenkins and Zuul CI are both popular continuous integration and delivery tools used in software development projects. While they share some similarities, there are several key differences between the two tools.

  1. Architecture: Jenkins is a standalone automation server, while Zuul CI is a highly scalable, multi-tenant continuous integration and delivery platform. Zuul CI is specifically designed for large-scale projects with a high degree of parallelism and distributed development teams.

  2. Workflow Management: Jenkins uses a traditional pipeline model, where multiple jobs are chained together to form a build pipeline. On the other hand, Zuul CI uses a unique pipeline model called the "Ansible-based, modern CI/CD workflow". This workflow allows developers to define and version control complex multi-stage pipelines as code.

  3. Branch and Change Management: Jenkins primarily focuses on branch-based workflows, where each branch triggers a separate build pipeline. Zuul CI, on the other hand, is built around a change-based system. It provides a robust mechanism to gate and test code changes before they are merged into a shared repository.

  4. Integration and Testing: Jenkins provides a wide range of plugins and integrations with external tools and services, making it highly customizable. Zuul CI, being managed by the OpenStack community, is tightly integrated with Zuul Ansible and OpenStack services, offering seamless testing and integration capabilities for OpenStack projects.

  5. Scalability: Jenkins can be easily set up and used on a single server, making it suitable for small to medium-sized projects. In contrast, Zuul CI is designed to handle large-scale projects with thousands of developers and extensive test coverage. It can scale horizontally across multiple servers to accommodate high workloads.

  6. Community and Support: Jenkins has a large and active community, with extensive documentation, tutorials, and community support. It has been widely adopted by organizations worldwide. Zuul CI, although gaining popularity, has a relatively smaller community and support base compared to Jenkins.

In summary, while both Jenkins and Zuul CI are powerful CI/CD tools, they differ in architecture, workflow management, branch and change management, integration and testing capabilities, scalability, and community support.

I'm open to anything. just want something that break less and doesn't need me to pay for it, and can be hosted on Docker. our scripting language is powershell core. so it's better to support it. also we are building dotnet core in our pipeline, so if they have anything related that helps with the CI would be nice.

ConcourseConcourse

I would definetly recommend Concourse to you, as it is one of the most advanced modern methods of making CI/CD while Jenkins is an old monolithic dinosaur. Concourse itself is cloudnative and containerbased which helps you to build simple, high-performance and scalable CI/CD pipelines. In my opinion, the only lack of skills you have with Concourse is your own knowledge of how to build pipelines and automate things. Technincally there is no lack, i would even say you can extend it way more easily. But as a Con it is more easy to interact with Jenkins if you are only used to UIs. Concourse needs someone which is capable of using CLIs.

From a StackShare Community member: "Currently we use Travis CI and have optimized it as much as we can so our builds are fairly quick. Our boss is all about redundancy so we are looking for another solution to fall back on in case Travis goes down and/or jacks prices way up (they were recently acquired). Could someone recommend which CI we should go with and if they have time, an explanation of how they're different?"

We use CircleCI because of the better value it provides in its plans. I'm sure we could have used Travis just as easily but we found CircleCI's pricing to be more reasonable. In the two years since we signed up, the service has improved. CircleCI is always innovating and iterating on their platform. We have been very satisfied.

As the maintainer of the Karate DSL open-source project - I found Travis CI very easy to integrate into the GitHub workflow and it has been steady sailing for more than 2 years now ! It works well for Java / Apache Maven projects and we were able to configure it to use the latest Oracle JDK as per our needs. Thanks to the Travis CI team for this service to the open-source community !

I use Google Cloud Build because it's my first foray into the CICD world(loving it so far), and I wanted to work with something GCP native to avoid giving permissions to other SaaS tools like CircleCI and Travis CI.

I really like it because it's free for the first 120 minutes, and it's one of the few CICD tools that enterprises are open to using since it's contained within GCP.

One of the unique things is that it has the Kaniko cache, which speeds up builds by creating intermediate layers within the docker image vs. pushing the full thing from the start. Helpful when you're installing just a few additional dependencies.

Feel free to checkout an example: Cloudbuild Example

Travis CITravis CI

I use Travis CI because of various reasons - 1. Cloud based system so no dedicated server required, and you do not need to administrate it. 2. Easy YAML configuration. 3. Supports Major Programming Languages. 4. Support of build matrix 6. Supports AWS, Azure, Docker, Heroku, Google Cloud, Github Pages, PyPi and lot more. 7. Slack Notifications.

You are probably looking at another hosted solution: Jenkins is a good tool but it way too work intensive to be used as just a backup solution.

I have good experience with Circle-CI, Codeship, Drone.io and Travis (as well as problematic experiences with all of them), but my go-to tool is Gitlab CI: simple, powerful and if you have problems with their limitations or pricing, you can always install runners somewhere and use Gitlab just for scheduling and management. Even if you don't host your git repository at Gitlab, you can have Gitlab pull changes automatically from wherever you repo lives.

If you are considering Jenkins I would recommend at least checking out Buildkite. The agents are self-hosted (like Jenkins) but the interface is hosted for you. It meshes up some of the things I like about hosted services (pipeline definitions in YAML, managed interface and authentication) with things I like about Jenkins (local customizable agent images, secrets only on own instances, custom agent level scripts, sizing instances to your needs).

Decisions about Jenkins and Zuul CI

Jenkins is a pretty flexible, complete tool. Especially I love the possibility to configure jobs as a code with Jenkins pipelines.

CircleCI is well suited for small projects where the main task is to run continuous integration as quickly as possible. Travis CI is recommended primarily for open-source projects that need to be tested in different environments.

And for something a bit larger I prefer to use Jenkins because it is possible to make serious system configuration thereby different plugins. In Jenkins, I can change almost anything. But if you want to start the CI chain as soon as possible, Jenkins may not be the right choice.
