Persona: Chaos/Resiliency/SRE, DevOps Engineer, Technical Engineering Manager

Abstract

LinkedIn and Mockito are two different use cases of implementing continuous delivery at scale. Yet the challenges, benefits and impact on the engineering culture are very similar.

In 2015, LinkedIn’s flagship application adopted a continuous delivery model we called 3x3: deploy to production 3 times a day, with a 3 hour maximum time from commit to production. At LinkedIn scale - hundreds of engineers building products for 500M users - implementing 3x3 was really hard. How did 3x3 change LinkedIn engineering culture and what we have learned on the way?

Mockito is a top 3 Java library with ~2M users. Even with that large user base, since 2014, the Mockito project has taken the surprising approach of publishing a new version of the library from every single pull request. This approach is challenging and innovative in the Java community, and Mockito leverages Shipkit to ship every change to production. Why did the Mockito team adopt continuous delivery in 2014 and what we have learned to date?

Join and learn from Szczepan Faber, the maker of Mockito framework since 2007, and the tech lead of LinkedIn Development Tools since 2015.

Speaker: Szczepan Faber

Creator of Mockito, Core eng of Gradle 1.x/2.x, & Tech Lead at LinkedIn Development Tools

Szczepan regularly gives lectures and instructs classes on development tools, engineering productivity, code review and testing. Since 2015, Szczepan Faber is a Tech Lead for LinkedIn Development Tools, responsible for developer productivity at LinkedIn. In 2011-2015 he was core engineer of Gradle 1.x and 2.x. and instructed numerous classes on build automation. Szczepan created Mockito framework in 2007, currently estimated user base of 2M, and has been giving classes on automated testing since. Szczepan publishes articles on LinkedIn, tweets as @MockitoGuy, makes tools on GitHub.
