Difficulty: EasyProvisioning Compute Engine and Kubernetes Engine Clusters

An infrastructure engineer needs to provision compute resources for an enterprise application that requires custom operating system kernel modifications and direct access to underlying virtual machine settings. The application must automatically scale out identical instances based on metric thresholds. Which compute provisioning strategy should the engineer select on Google Cloud Platform?

  1. Create an instance template specifying the custom VM configuration and deploy a Managed Instance Group (MIG) configured with autoscaling.Answer
  2. B
    Provision a Google Kubernetes Engine (GKE) cluster to run the application containers with custom node kernel parameters.
  3. C
    Deploy unmanaged Compute Engine instances using a service account assigned the primitive Owner role.
  4. D
    Provision individual Compute Engine instances on demand without verifying or requesting regional vCPU quota increases prior to deployment.

Answer

Create an instance template specifying the custom VM configuration and deploy a Managed Instance Group (MIG) configured with autoscaling.
Creating an instance template with the required custom virtual machine configuration and provisioning a Managed Instance Group (MIG) enables automated, policy-based scaling of identical Compute Engine instances.

Step-by-Step Solution

1
Identify workload infrastructure requirements
The application requires custom kernel modifications and automatic scaling of identical virtual machine instances.
Compute Engine virtual machines support low-level guest OS and kernel modifications, whereas standard container platforms restrict direct host kernel modification.
2
Select the optimal compute provisioning and scaling method
Define an instance template and launch a Managed Instance Group (MIG) with autoscaling.
Instance templates encapsulate custom instance configuration, and MIGs automate scaling out identical Compute Engine instances based on metrics.
