Exam Associate Cloud Engineer topic 1 question 277 discussion

If the application did not have to be run on VMs I would have chosen D as Cloud Run would be easier and can scale to zero which reduces idle-time cost. But the app does, so MIGs is the choice.

MIG supports stateless applications.

Vote for A

Here's why A is the most suitable solution: Managed Instance Groups (MIGs): MIGs are designed to manage groups of identical VMs, making them ideal for running stateless applications. They provide features like auto-scaling, auto-healing, and load balancing, which are crucial for handling fluctuating traffic. Autoscaling: You can configure autoscaling policies to automatically add or remove VM instances based on metrics like CPU utilization, HTTP load balancing traffic, or Stackdriver Monitoring metrics. This ensures that your application can scale up to handle peak traffic and scale down during periods of low demand.
