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
