You support a production service that runs on a single Compute Engine instance. You regularly need to spend time on recreating the service by deleting the crashing instance and creating a new instance based on the relevant image. You want to reduce the time spent performing manual operations while following Site
Reliability Engineering principles. What should you do?

A. File a bug with the development team so they can find the root cause of the crashing instance. B. Create a Managed instance Group with a single instance and use health checks to determine the system status. C. Add a Load Balancer in front of the Compute Engine instance and use health checks to determine the system status. D. Create a Stackdriver Monitoring dashboard with SMS alerts to be able to start recreating the crashed instance promptly after it was crashed.
