11. Facing problems
    ● Job queue congestion, long time waiting
    ○ Peak time is early evening in Japan
    ■ Global team members start working
    ○ Increasing mobile app projects
    ● CI machines scaling is hard
    ○ Specially, mac for iOS apps (shortage of set up automation, physical machines)
    ● Make self-service as much as possible on project
    ○ Project member ops faster than wait for mobile-infra team ops
    ○ Make a project team select technical means (includes CI services)

12. Our hope to cloud CI services
    ● Easy CI stacks scaling
    ○ Good provisioning tools support
    ○ Flexible CI Stacks Scaling (e.g. considered peak time, number of jobs, etc...)
    ● Wide choice development environment support
    ○ Xcode/Android SDK versions, React Native etc…
    ● Easy set up build steps, management, reusability
    ● Early follow to dev tools updates
