Your application is deployed in a Google Kubernetes Engine (GKE) cluster. When a new version of your application is released, your CI/CD tool updates the spec.template.spec.containers[0].image value to reference the Docker image of your new application version. When the Deployment object applies the change, you want to deploy at least 1 replica of the new version and maintain the previous replicas until the new replica is healthy. Which change should you make to the GKE Deployment object shown below? 

Your team detected a spike of errors in an application running on Cloud Run in your production project. The application is configured to read messages from Pub/Sub topic A, process the messages, and write the messages to topic B. You want to conduct tests to identify the cause of the errors. You can use a set of mock messages for testing. What should you do?

They willneed to ensure that the application scales smoothly and provides clear uptime data.Existing Technical EnvironmentHipLocal'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 RequirementsHipLocal's investors want to expand their footprint and support the increase in demand they are seeing. Theirrequirements 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 has connected their Hadoop infrastructure to GCP using Cloud Interconnect in order to query datastored on persistent disks.Which IP strategy should they use?
