Google Cloud Build vs Bamboo comparison of Continuous Integration servers

	Google Cloud Build https://cloud.google.com/cloud-build/	Bamboo https://www.atlassian.com/software/bamboo
Unique feature	Security / speed	Atlassian suite integration
Type of product	SaaS	On Premise
Offers a free plan	Yes Google offers a generous 120 build-minutes per day plan, not including time spent waiting in the queue.	Yes The full Atlassian suite is free for open source projects (https://www.atlassian.com/software/views/open-source-license-request). For all others, they offer a minimal free trial.
Predictable pricing	Yes (partial) While it's clear what the cost is (priced per build-minute), figuring out costs can be a hassle, especially as the price can vary quite a bit depending on commits to the project.	Yes They price their product based on number of build agents (more concurrency, more expensive). Given the notoriety and depth of the Atlassian suite, the pricing can be steep for small companies.
Support / SLA	Yes Even available as a paid add-on, for 24/7 phone support for example: https://cloud.google.com/support/	Yes Dedicated tehnical support.
Paralellism Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro	Yes	Yes Up to 100 parallel agents
Distributed builds distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro	N/A	Yes Agents can run on multiple machines.
Containers support / Build environment	Yes Native Docker and Packer support	Yes By default, they offer Docker support for the CI/CD job runners.
Analytics / Status overview Analytics and overview referrs to the ability to, at a glance, see what's breaking (be it a certain task, or the build for a specific project)	Yes	Yes Excellent dashboards, even more so thanks to integrations with the other tools in the Atlassian arsenal
Management support How easy is it to manage users / projects / assign roles and permissions and so on	Yes	Yes Great management support, built for large scale companies, even allows setting per-environment permissions (ie: QA team can only deploy to their own, isolated environment)
Self-hosted option	No (partial) While there's no self hosted variant, they provide a local Cloud Build image which allows you to build locally, very valuable for debugging.	Yes
Hosted plans / SaaS	Yes	No
Build pipelines A continuous delivery pipeline is a description of the process that the software goes through from a new code commit, through testing and other statical analysis steps all the way to the end-users of the product.	Yes Configurable via YML and/or JSON files.	Yes Advanced pipeline support - with features built for feature branch support, various triggers, schedules, external notifications and more.
Reports Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard.	Yes	Yes
Ecosystem Besides the official documentation and software, is there a large community using this product? Are there any community-driven tools / plugins that you can use?	Yes There are predefined images built for Cloud Build, which can be integrated right away in your build process. Some of them are first party: https://github.com/GoogleCloudPlatform/cloud-builders and others are community contributed: https://github.com/GoogleCloudPlatform/cloud-builders-community	Yes Large selection (~200) of apps that integrate with Bamboo, available on the official marketplace for Bamboo: https://marketplace.atlassian.com/addons/app/bamboo
Specific language support: Ruby Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those. Some others make it even easier by detecting Gemfiles or package.json and automate parts of the process for the developer.	N/A Nothing specific as far as we can tell	Yes (partial) It looks like the documentation and features for Ruby are lagging behind. All I could find is this repo: https://github.com/drscream/bamboozled-ruby-plugin, following this support ticket: https://jira.atlassian.com/browse/BAM-10948 from this documentation stub page: https://confluence.atlassian.com/bamboo0601/getting-started-with-ruby-and-bamboo-935580774.html
Specific language support: JavaScript	Yes (partial) npm, yarn and jasmine-node support via predefined Cloud Build steps.	No No specific support, beyond some documentation on integrating Selenium (not marked as partial support since that documentation is only promoted in the Atlassian docs, but is hosted by BrowserStack)
Integrations 1st party support for common tools (like Slack notifications, various VCS platforms, etc)	Yes Various integrations available via custom Build Steps, as well as natively (Kubernetes, Docker, etc.)	Yes Deep integration with the Atlassian product stack (Jira, etc.).
API Custom integreation is available, via an API or otherwise, it's mentioned separately as it allows further customization than any of the Ecosystem/Integration options	Yes REST API and comprehensive CLI tool, as well as a pub/sub system for build notifications.	Yes
Auditing	Yes	Yes
Additional notes	Not unlike other Google tools, there's a strong emphasis on allowing developers to build on top of the service. Becomes more valuable if you're using other Google Cloud services as well.	Not really something that should be purchased separatelly from the Atlassian stack.
