Continuous integration is the lifeblood of any software house and extremely important in a fast-growing organisation like Atlassian. You'll hear about how the build engineering team have scaled their team, infrastructure and Bamboo over their four-year journey of continuous improvement to provide a build platform and services used internally within the organization. You'll hear about how the team has grown from three engineers servicing 300 Atlassians to 12 engineers handling over 1300 Atlassians, handling challenges such as balancing firefighting and project work. You'll hear how we've come from infrastructure that was a group of pets, to cattle, then to stateless machines; how we manage our internal Bamboo instances, balancing dogfooding new milestones and providing a critical service to the organization.
