The full test suite takes several hours to complete, running on a limited number of on premises servers reserved for testing. Your company wants to move the testing infrastructure to the cloud, to reduce the amount of time it takes to fully test a change to the system, while changing the tests as little as possible. Which cloud infrastructure should you recommend?

1. A. Google Compute Engine unmanaged instance groups and Network Load Balancer
2. B. Google Compute Engine managed instance groups with auto-scaling
3. C. Google Cloud Dataproc to run Apache Hadoop jobs to process each test
4. D. Google App Engine with Google Stackdriver for logging

Google Compute Engine enables users to launch virtual machines (VMs) on demand. VMs can be launched from the standard images or custom images created by users.
Managed instance groups offer autoscaling capabilities that allow you to automatically add or remove instances from a managed instance group based on increases or decreases in load. Autoscaling helps your applications gracefully handle increases in traffic and reduces cost when the need for resources is lower.
