Introductory Info Company overview -

Mountkirk Games makes online, session-based, multiplayer games for mobile platforms. They have recently started 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 digital banner 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's backend on Google Kubernetes Engine so they can scale rapidly and use Google's global load balancer to route players to the closest regional game arenas. In order to keep the global leader board in sync, they plan 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 Cloud project 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 development and testing.

Business requirements -

Support multiple gaming platforms.

Support multiple 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 migration of 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 analyze player 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 our deployments of bug fixes and new functionality. Question Mountkirk Games wants you to secure the connectivity from the new gaming application platform to Google Cloud. You want to streamline the process and follow

Google-recommended practices. What should you do?

Your operations team has asked you to help diagnose a performance issue in a production application that runs on Compute Engine. The application is dropping requests that reach it when under heavy load. The process list for affected instances shows a single application process that is consuming all available CPU, and autoscaling has reached the upper limit of instances. There is no abnormal load on any other related systems, including the database. You want to allow production traffic to be served again as quickly as possible. Which action should you recommend?

As a cloud architect, you are managing a project that consists of a single Virtual Private Cloud (VPC) and a single subnetwork located in the us-west1 region. Within this subnetwork, there is a Compute Engine instance hosting an application. Now, your development team intends to deploy a new instance within the same project, but in the europe-central2 region. They require access to the application and wish to adhere to Google's best practices. As a cloud architect, what guidance should you provide in this situation?

When planning your migration, you find out that some members of the network management team will need to be able to manage all network components, but other team members will only need read access. What mechanism should you use to control this?

A motor company has launched a smart helmet that detects and reports accidents immediately. Each helmet has the capability to send 10 kb of biometric data in JSON format, collect biometric data from different platforms every second, process that data into a machine learning model, predict and detect if an accident has occurred, and send a notification. The main task for company developers is to architect a platform that matches up with the following requirements: • Real-time analyses of biometric data • The biometric data should be highly flexible and aligned • In the future, the service should be more efficient in accident detection and prepare proper remedies for it Which of the following architectures should you recommend for the above requirements?
