QUESTION 317

Introductory Info Company overview -

Mountkirk Games makes online, session-based, multiplayer games for mobile platforms. They have recentlystarted expanding to other platforms after successfully migrating their on-premises environments to Google Cloud.

Their most recent endeavor is to create a retro-style first-person shooter (FPS) game that allows hundreds of simultaneous players to join a geo-specific digital arena from multiple platforms and locations. A real- time digitalbanner will display a global leaderboard of all the top players across every active arena.

Solution concept -

Mountkirk Games is building a new multiplayer game that they expect to be very popular. They plan to deploy the game TMs backend on Google Kubernetes Engine so they can scale rapidly and use Google TMs global loadbalancer to route players to the closest regional game arenas. In order to keep the global leader board in sync, theyplan to use a multi-region Spanner cluster.

Existing technical environment -

The existing environment was recently migrated to Google Cloud, and five games came across using lift- and-shift virtual machine migrations, with a few minor exceptions. Each new game exists in an isolated Google Cloudproject nested below a folder that maintains most of the permissions and network policies. Legacy games with low traffic have been consolidated into a single project. There are also separate environments for developmentand testing.

Business requirements -

Support multiple gaming platforms. Supportmultiple regions.

Support rapid iteration of game features.Minimize latency.

Optimize for dynamic scaling.

Use managed services and pooled resources.Minimize costs.

Technical requirements -

Dynamically scale based on game activity.

Publish scoring data on a near real-time global leaderboard. Store game activity logs in structured files for future analysis. Use GPU processing to render graphics server-side for multi-platform support. Support eventual migrationof legacy games to this new platform.

Executive statement -

Our last game was the first time we used Google Cloud, and it was a tremendous success. We were able to analyzeplayer behavior and game telemetry in ways that we never could before. This success allowed us to bet on a full migration to the cloud and to start building all-new games using cloud-native design principles. Our new game is our most ambitious to date and will open up doors for us to support more gaming platforms beyond mobile. Latency is our top priority, although cost management is the next most important challenge. As with our first cloud-based game, we have grown to expect the cloud to enable advanced analytics capabilities so we can rapidly iterate on ourdeployments of bug fixes and new functionality.
