Question

You support a web application that runs on App Engine and uses CloudSQL and Cloud Storage for data storage. After a short spike in website traffic, you notice a big increase in latency for all user requests, increase in CPU use, and the number of processes running the application. Initial troubleshooting reveals: - After the initial spike in traffic, load levels returned to normal but users still experience high latency. - Requests for content from the CloudSQL database and images from Cloud Storage show the same high latency. - No changes were made to the website around the time the latency increased. - There is no increase in the number of errors to the users. You expect another spike in website traffic in the coming days and want to make sure users don't experience latency. What should you do?

Options

  • AUpgrade the GCS buckets to Multi-Regional.
  • BEnable high availability on the CloudSQL instances.
  • CMove the application from App Engine to Compute Engine.
  • DModify the App Engine configuration to have additional idle instances.
