CI/CD Cost Optimization

1 post · Nov 2024 – Oct 2025

What this trail covers

This capability tracks the evolution of CI/CD systems, focusing on cost-effectiveness, scalability, and developer productivity. It encompasses comparisons between self-hosted solutions (like Jenkins) and SaaS offerings (like Bitbucket Pipelines), analyzing total cost of ownership (TCO) beyond raw compute costs. Key aspects include managing variable CI/CD loads, the operational overhead of self-hosted platforms, and the benefits of elastic scaling provided by SaaS solutions. The capability also includes tools and strategies for migrating between CI/CD platforms, such as the Jenkins to Bitbucket Pipelines Migration Tool, which automates the conversion of Jenkinsfiles to Bitbucket Pipelines YAML syntax, offering extensibility for custom plugins and configurations.

All Atlassian trails
  1. Why Jenkins might cost you 10x more than Bitbucket PipelinesThis post argues that self-hosted CI/CD solutions like Jenkins are often more expensive than SaaS offerings like Bitbucket Pipelines due to the hidden costs of managing infrastructure and the need for dedicated platform engineering teams. It provides a detailed cost comparison for a 500-developer team, highlighting that the total cost of ownership for a DIY auto-scaling platform (including compute and platform engineering staff) can be over 10x higher than Bitbucket Pipelines. The post also references Atlassian's internal reinvention of its CI/CD, which led to significant cost savings and allowed build engineering teams to focus on developing new tools. It emphasizes the benefits of SaaS CI/CD, such as elastic scaling, varied runner sizes, isolated environments, and dynamic pipelines for security and cost management.
  2. To Bitbucket from Jenkins: Enhancing Developer ExperienceThis post details the author's experience setting up a Jenkins CI/CD system on AWS to compare it against Bitbucket Pipelines. It highlights the significant overhead and emergent work involved in managing a self-hosted Jenkins instance, including EC2 setup, dependency management, plugin installation, integration with Bitbucket, and compliance with internal engineering standards. The author contrasts this with the out-of-the-box integration and reduced operational burden of Bitbucket Pipelines. The post also introduces the use of Rovo Dev CLI to assist in writing Jenkinsfiles and updating Jira issues, demonstrating how AI tools can improve developer experience within CI/CD workflows.
  3. General availability of the Jenkins to Bitbucket Pipelines migration toolThis post announces the general availability of the Jenkins to Bitbucket Pipelines migration tool. Key updates include support for 12 additional plugins, mapping of parallel stages in Jenkins to parallel steps in Bitbucket Pipelines, and support for plugins used in over 5% of Jenkins instances. Unsupported plugins are copied as-is with clear marking for manual translation. The tool allows for custom translation logic and accepts plugin requests from the community. Documentation and a guided demo are provided.
  4. Introducing the Jenkins to Bitbucket Pipelines migration toolIntroduces an open-source, automated tool to migrate CI/CD workflows from Jenkins to Bitbucket Pipelines. The tool converts declarative Jenkins files to Bitbucket Pipelines YAML syntax, marking unconverted elements for manual review. It is designed with extensibility for custom translation logic and community contributions for additional Jenkins plugin support. The post highlights the benefits of migrating to Bitbucket Pipelines, including reduced operational overhead, elastic scaling, and potential cost savings compared to self-hosted solutions.
