The internship
1) An intern created a project to add load balancing capabilities to Facebook's DHCP infrastructure after hearing a talk about issues with uneven traffic balancing. 2) Over the course of a 12 week internship, the intern prototyped, developed, and rolled out the project which resulted in a new open source DHCP load balancer called DHCPLB. 3) The internship project process involved engineering and team onboarding, feature development, controlled production rollout, and ultimately open sourcing the project.
The internship
- 1. The internship Angelo Failla Production Engineer Clusterinfrastructure team Facebook Ireland From hackathon idea to production: story of an intern project
- 2. Approximately one year ago…at SRECon15 Europe… I gave a talk about our DHCP infra…
- 3. Slide Subtitle I wasabout to wrap it up, then somebody asked me… “Have you checked that your DHCP traffic is evenly balanced?”
- 6. Fast forward oneyear later, April 2016…
- 8. <<A "good hack"is a clever solution to a programming problem and "hacking" is the act of doing it>> — Eric S. Raymond The meaning of ‘Hack’: http://www.catb.org/jargon/html/meaning-of-hack.html
- 9. Hacking is centralpart of our culture
- 11. We hacked aload balancer
- 12. POC done in2d, shown @ prototype forum
- 13. Fast forward tobeginning of “Summer”…
- 14.
- 15. • 12 weeksin total • 1 week of engineering onboarding • team/project onboarding • feature development • controlled production rollout • open source it! Intern summer project: milestones DHCPLB: a DHCP relayer with load balancing capabilities

- 17. What I’ve learnedfrom this story.
- 18. Public speaking fear,are people even listening to me?
- 19. Hackathons are powerfulthings
- 20. Managing (interns) ishard but rewarding
- 21. Explain the Companyvalues

- 23. Make sure internssocialize and have fun!
Editor's Notes
- #3 BGP is the protocol we use to figure out which server is closer to a given client, but it’s not aware about load Explain how DHCP is used
- #4 Explain how DHCP is used
- #9 Hacking is ‘an appropriate application of ingenuity’. Quick-and-dirty patchwork job or carefully crafted work of art. You still have to admire the cleverness that went into it.
- #11 Talk about hackathons at FB. held periodically, 1 or 3 days something done quickly food/drinks/socialize/know new people work on stuff you don’t normally work on like button, timeline and chat started as hackathon proj
- #12 We used go because we wanted to learn, my team doesn’t use it, I wanted to learn and we find the language was suitable for the problem. Suitable for hackathon.
- #13 Talk about prototype forums.
- #22 Teach new people about the important of fast iterative dev cycles to gather lots of feedback. Most inexperienced people tend to submit code for review only when they think it is perfect.
- #23 Talk about the fact that I went away for 2 weeks. Make sure you haven’t told them everything but they can figure out by themselves.
- #24 Talk about events we organize, Friday booze and banter, etc.
