Mountkirk Games makes online, session-based, multiplayer games for popular mobile platforms. Historically, they used cloud providers to lease physical servers and faced issues with scaling their global audience, application servers, MySQL databases, and analytics tools due to unexpected popularity. For their new game, which is expected to be very popular, they plan to deploy the backend on Google Compute Engine to capture streaming metrics, run intensive analytics, and take advantage of autoscaling and managed NoSQL services. Mountkirk Games wants you to design their new testing strategy. How should the test coverage differ from their existing backends on the other platforms?
