10. Ambitions •  Provide a simple framework for us to build an efficient, resilient, second generation Hailo •  Allow Hailo to scale the business along three axis: adding features to our current business, adding cities and brand new stuff •  Solve pain points in our current architecture •  Be productive

12. Key features •  Lose PHP, adopt Go – gains in efficiency of developer time and compute resource •  Eliminate all SPOFs – adopt a cloud native approach to build a working whole out of ephemeral and often broken parts •  Scale engineering output in line with additional resource – services with few, clearly defined responsibilities reduce friction •  Increase reusability – develop features by composing fine-grained services that are agnostic to Hailo’s current operation
13. Move fast: build a service in 30 minutes
14. Move fast: reuse existing services to build features ETA Service Routing Service Phone Service Profile Service Login Service State Service Charge Service Near Drivers Service Tow Truck Service Restau- rant Service Place Service
15. Move fast: simple global deployment
17. Move fast: powerful tools for developer insight

19. June July Aug Sept Oct Nov Dec July 26th Launch 9 services in production to handle driver location updates, bypassing H1 PHP
20. June July Aug Sept Oct Nov Dec September 5th Launch 2 new services in production to power AB testing system. During the first week of operation this processes nearly 1B events.
22. June July Aug Sept Oct Nov Dec September 27th First demonstration of “tech free city” driver registration completed in our test environment. Total H2 services now around 20.
23. June July Aug Sept Oct Nov Dec November 8th First integration of the entire H2 job flow with the new Driver 2 app – entirely server configured. Total H2 services now around 60.
25. June July Aug Sept Oct Nov Dec December 15th Alpha production release of tech-free city to Atlanta.
