6. Product ServicesStorage Services & Storage for our games

7. Product Services – Leaderboard – Flights (a/b testing) – Push Notification – Social (gifts/etc) – User/Save files – Logs & Metrics – Game Logic Storage – Additional content (more levels, more puzzles) – Binary limit (10mb in early days, now 100mb) – Facebook share images (attachment => more permissions)

8. Information Architecture

9. Information Architecture on AWS Red = Storage Blue = Compute Yellow = Load Balancer Green = Data flow Front-End EC2 Game Content S3 Leaderboards, Game Config, A/B Testing, Social, User Data, Logs & Metrics RDS Front-End EC2 Games & Apps Very Simple!

10. Mobile Apps/Games Most mobile apps/games have more simple back-end requirements so you have services like https://parse.com/https://parse.com/

11. Key Decision All compute nodes run all services for all games (generalized nodes) – Easier to scale – Better load balancing Tier 1/Tier 2 RDS – I actually have 2 RDS services – Tier 1 (user data) – Tier 2 (logs/metrics) => more data, less stable Dashboard calculates every 3 hours – No worker role. Basically just web role forks out thread to do work every 3 hours.

12. Dashboard Stats aren’t exactly right. Pirates!

13. Continuous Integration https://circleci.com/ GitHub Dev CircleCI Test Container (EC2) Kooapps production servers (EC2) Pass Fail
