A fifteen minute presentation I gave at the 21st Japan AWS User's Group in Sapporo (on 2018/11/15) giving an overview of the changes that were made to our AWS infrastructure and CI/CD build pipeline over a year from the initial release of Crystal Clash. I also cover how we make use of PHP with AWS Lambda to provide access to the game API from iOS/Android devices.
(Note: This presentation is only in Japanese, sorry.)
