Are Hosted CI-as-a-Service Offerings All Based on Jenkins as Their Core Engine?

When it comes to hosted Continuous Integration (CI) solutions, many people assume that all of the major CI-as-a-service providers are built around Jenkins as their core engine. However, the reality is more complex than that. Let's delve into why some hosted CI services use Jenkins while others have chosen alternative approaches.

Jenkins: The Dominant Player

Jenkins is widely recognized as one of the most popular and versatile open-source CI tools. It has a massive user base and a rich ecosystem of plugins, making it a go-to choice for many organizations. However, not all hosted CI-as-a-service solutions rely on Jenkins.

Legacy vs. Custom Solutions

The question of whether hosted CI-as-a-service offerings are all based on Jenkins can be answered with a resounding 'No.' Several well-known CI-as-a-service providers such as Codeship, CircleCI, and Travis CI are either built on top of their own proprietary solutions or utilize more modern, forward-thinking open-source projects. This decision is driven by several factors, including maintaining a competitive edge and addressing the specific needs of their users.

Why Not Jenkins?

Jenkins comes with numerous drawbacks that make it a less-than-ideal choice for some hosted CI services. The primary concerns include:

Customization: Jenkins' extensive configuration options and plugins can add complexity and maintenance overhead. While flexibility is a plus, it can also lead to a sprawling and difficult-to-manage system. Dependencies: Jenkins has a long history and comes with a ton of dependencies. Replacing it or rebuilding it from scratch is a significant undertaking. Performance: Jenkins was initially designed as a job scheduler and executor for on-premises environments. As hosted services, these providers often need a more streamlined and efficient tool. Proprietary Solutions: Building a proprietary solution allows providers to offer a more tailored and efficient service.

Proprietary Solutions and Modern Alternatives

Hosted CI-as-a-service providers have recognized the limitations of Jenkins and have developed their own solutions. For example:

Codeship: Codeship has its own proprietary CI platform designed specifically for hosted environments. CircleCI: While CircleCI uses a combination of open-source tools, it has also developed its own internal solutions to improve performance and efficiency. Travis CI: Travis CI runs on a custom-built system optimized for its hosted environment.

Developing a custom solution or leveraging modern open-source alternatives (such as codeship CI-as-a-service, GitHub Actions, or Azure DevOps) allows these providers to:

Offer a Simplified Experience: A simpler, more streamlined interface that is optimized for hosted services. Improve Performance: Tailored to the hosted environment, these solutions are often more efficient and performant. Ensure Security: Implementing custom solutions allows for better control over security and compliance.

The Future of CI-as-a-Service

As the CI-as-a-service market continues to evolve, we can expect to see a greater trend toward proprietary solutions and modern alternatives. These providers are more focused on delivering a seamless, efficient, and secure experience for their users. While Jenkins remains a powerful tool for on-premises CI, its complexity and limitations make it less suitable for hosted services.

In conclusion, not all hosted CI-as-a-service offerings are based on Jenkins as their core engine. Providers have embraced proprietary solutions and modern alternatives to offer tailored, efficient, and secure services to their users. The key takeaway is that flexibility and performance are crucial in the hosted CI-as-a-service landscape, and this often requires custom-built solutions.
