An application is being managed on a Compute Engine instance, alongside multiple backend services that are run on stand-alone Docker containers in Compute Engine instances. These Compute Engine instances supporting the backend services are scaled by managed instance groups across several regions. In order to ensure a loosely coupled calling application, it is necessary to be able to invoke individual service implementations which are selected based on the value of an HTTP header located within the request.What is the appropriate Google Cloud feature to activate the backend services?

Your application is logging to Stackdriver. You want to get the count of all requests on all /api/alpha/* endpoints. What should you do?

After deploying your application in Google Kubernetes Engine, you now require the release of a new version of the application. It is essential to have the capability to promptly revert to the previous version in case complications arise with the latest version.What would be the most suitable deployment model to use?

Itis used for event planning and organizing sporting events, and for businesses to connect with their localcommunities. HipLocal launched recently in a few neighborhoods in Dallas and is rapidly growing into a globalphenomenon. Its unique style of hyper-local community communication and business outreach is in demandaround the world.Executive StatementWe are the number one local community app; it's time to take our local community services global. Our venturecapital investors want to see rapid growth and the same great experience for new local and virtual communitiesthat come online, whether their members are 10 or 10000 miles away from each other.Solution ConceptHipLocal wants to expand their existing service, with updated functionality, in new regions to better serve theirglobal customers. They want to hire and train a new team to support these regions in their time zones. 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 wants to reduce the number of on-call engineers and eliminate manual scaling.Which two services should they choose? (Choose two.)

Azgomi is a popular community application that facilitates communication between people in close proximity. It is used for event planning, organizing sporting events, and connecting businesses with their local communities. Although it launched recently in a few neighborhoods in Dallas, it is rapidly expanding into a global phenomenon. The company's venture capital investors are looking for rapid growth and expansion into new regions, offering the same experience to users, regardless of their location.Azgomi wants to expand its service to new regions, with updated functionality to better serve its global customers. They plan to hire and train a new team to support these regions in their respective time zones. It is essential that the application scales smoothly and provides clear uptime data, and that they analyze and respond to any issues that occur. The existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. The application runs on Compute Engine virtual machine instances hosted in GCP. State is stored in a single instance MySQL database in GCP. Release cycles include development freezes to allow for QA testing. The application has no logging. Applications are manually deployed by infrastructure engineers during periods of slow traffic on weekday evenings. There are basic indicators of uptime, and alerts are frequently fired when the APIs are unresponsive.Azgomi's investors want to expand its footprint and support the increase in demand they are seeing. They require the following:• Expand availability of the application to new regions.• Support 10x as many concurrent users.• 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 Google-recommended practices for cloud computing.○ Develop standardized workflows and processes around application lifecycle management.○ Define service level indicators (SLIs) and service level objectives (SLOs).The technical requirements for Azgomi include:• Providing secure communications between the on-premises data center and cloud-hosted applications and infrastructure.• The application must provide usage metrics and monitoring.• APIs require authentication and authorization.• Implement faster and more accurate validation of new features.• Logging and performance metrics must provide actionable information to be able to provide debugging information and alerts.• Must scale to meet user demand.What steps can Azgomi take to revamp their architecture in order to accommodate a significant surge in user traffic?
