You need to select and configure compute resources for a set of batch processing jobs. These jobs take around 2 hours to complete and are run nightly. You want to minimize service costs. What should you do?

A.
Select Google Kubernetes Engine. Use a single-node cluster with a small instance type.
Answers
A.
Select Google Kubernetes Engine. Use a single-node cluster with a small instance type.
B.
Select Google Kubernetes Engine. Use a three-node cluster with micro instance types.
Answers
B.
Select Google Kubernetes Engine. Use a three-node cluster with micro instance types.
C.
Select Compute Engine. Use preemptible VM instances of the appropriate standard machine type.
Answers
C.
Select Compute Engine. Use preemptible VM instances of the appropriate standard machine type.
D.
Select Compute Engine. Use VM instance types that support micro bursting.
Answers
D.
Select Compute Engine. Use VM instance types that support micro bursting.
Suggested answer: C

Explanation:

If your apps are fault-tolerant and can withstand possible instance preemptions, then preemptible instances can reduce your Compute Engine costs significantly. For example, batch processing jobs can run on preemptible instances. If some of those instances stop during processing, the job slows but does not completely stop. Preemptible instances complete your batch processing tasks without placing additional workload on your existing instances and without requiring you to pay full price for additional normal instances.
