In a Personalized Nutrition Service company, the application is running on App Engine and is accessed globally through different devices. Which metric should be used in Cloud Monitoring for App Engine to determine the number of connections?

You support a high-traffic web application with a microservice architecture. The home page of the application displays multiple widgets containing content such as the current weather, stock prices, and news headlines. The main serving thread makes a call to a dedicated microservice for each widget and then lays out the homepage for the user. The microservices occasionally fail; when that happens, the serving thread serves the homepage with some missing content. Users of the application are unhappy if this degraded mode occurs too frequently, but they would rather have some content served instead of no content at all. You want to set a Service Level Objective (SLO) to ensure that the user experience does not degrade too much. What Service Level Indicator {SLI) should you use to measure this?

Your company processes IOT data at scale by using Pub/Sub, App Engine standard environment, and an application written in GO. You noticed that the performance inconsistently degrades at peak load. You could not reproduce this issue on your workstation. You need to continuously monitor the application in production to identify slow paths in the code. You want to minimize performance impact and management overhead. What should you do?

• Install a continuous profiling tool into Compute Engine. Configure the application to send profiling data to the tool.
  

As a social impact investment platform company, you want to ensure that images deployed to your application services in Google Kubernetes Engine (GKE) are only from the centrally-managed GoogleContainerRegistry (GCR) image registry in the altostrat-images project. How can you achieve this goal while minimizing development time?
