Exam 13: Professional Cloud Developer

You are planning to deploy your application in a Google Kubernetes Engine (GKE) cluster. Your application can scale horizontally, and each instance of your application needs to have a stable network identity and its own persistent disk. Which GKE object should you use?

You need to migrate an internal file upload API with an enforced 500-MB file size limit to App Engine. What should you do?

Case Study Company Overview HipLocal is a community application designed to facilitate communication between people in close proximity. It is used for event planning and organizing sporting events, and for businesses to connect with their local communities. HipLocal launched recently in a few neighborhoods in Dallas and is rapidly growing into a global phenomenon. Its unique style of hyper-local community communication and business outreach is in demand around the world. Executive Statement We are the number one local community app; it's time to take our local community services global. Our venture capital investors want to see rapid growth and the same great experience for new local and virtual communities that come online, whether their members are 10 or 10000 miles away from each other. Solution Concept HipLocal wants to expand their existing service, with updated functionality, in new regions to better serve their global customers. They want to hire and train a new team to support these regions in their time zones. They will need to ensure that the application scales smoothly and provides clear uptime data. Existing Technical Environment HipLocal's environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. The HipLocal team understands their application well, but has limited experience in global scale applications. Their existing technical environment is as follows: • Existing APIs run on Compute Engine virtual machine instances hosted in GCP. • State is stored in a single instance MySQL database in GCP. • Data is exported to an on-premises Teradata/Vertica data warehouse. • Data analytics is performed in an on-premises Hadoop environment. • The application has no logging. • There are basic indicators of uptime; alerts are frequently fired when the APIs are unresponsive. Business Requirements HipLocal's investors want to expand their footprint and support the increase in demand they are seeing. Their requirements are: • Expand availability of the application to new regions. • Increase the number of concurrent users that can be supported. • Ensure a consistent experience for users when they travel to different regions. • Obtain user activity metrics to better understand how to monetize their product. • Ensure compliance with regulations in the new regions (for example, GDPR). • Reduce infrastructure management time and cost. • Adopt the Google-recommended practices for cloud computing. Technical Requirements • The application and backend must provide usage metrics and monitoring. • APIs require strong authentication and authorization. • Logging must be increased, and data should be stored in a cloud analytics platform. • Move to serverless architecture to facilitate elastic scaling. • Provide authorized access to internal apps in a secure manner. HipLocal wants to reduce the number of on-call engineers and eliminate manual scaling. Which two services should they choose? (Choose two.)

You are planning to deploy your application in a Google Kubernetes Engine (GKE) cluster. The application exposes an HTTP-based health check at /healthz. You want to use this health check endpoint to determine whether traffic should be routed to the pod by the load balancer. Which code snippet should you include in your Pod configuration?

Your application performs well when tested locally, but it runs significantly slower when you deploy it to App Engine standard environment. You want to diagnose the problem. What should you do?
