Topic 1 Question 8
A company is migrating a distributed application to AWS. The application serves variable workloads. The legacy platform consists of a primary server that coordinates jobs across multiple compute nodes. The company wants to modernize the application with a solution that maximizes resiliency and scalability. How should a solutions architect design the architecture to meet these requirements?
- Configure an Amazon Simple Queue Service (Amazon SQS) queue as a destination for the jobs. Implement the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure EC2 Auto Scaling to use scheduled scaling.
- Configure an Amazon Simple Queue Service (Amazon SQS) queue as a destination for the jobs. Implement the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure EC2 Auto Scaling based on the size of the queue.
- Implement the primary server and the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure AWS CloudTrail as a destination for the jobs. Configure EC2 Auto Scaling based on the load on the primary server.
- Implement the primary server and the compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group. Configure Amazon EventBridge (Amazon CloudWatch Events) as a destination for the jobs. Configure EC2 Auto Scaling based on the load on the compute nodes.

- 正解だと思う選択肢: B
  A - incorrect: Schedule scaling policy doesn't make sense. C, D - incorrect: Primary server should not be in same Auto Scaling group with compute nodes. B is correct.

- 正解だと思う選択肢: B
  The answer seems to be B for me: A: doesn't make sense to schedule auto-scaling C: Not sure how CloudTrail would be helpful in this case, at all. D: EventBridge is not really used for this purpose, wouldn't be very reliable

  A: Incorrect - the question don't mention about schedule for high workload. So we don't use scheduled scaling for this case. B: Correct - SQS can keep your message in the queue in case of high workload and if it too high we can increase the EC2 instance base on size of the queue. C: Incorrect - AWS CloudTrail is API logs it is use for audit log of AWS user activity. D: Incorrect - Event Bridge is use for filter event and trigger event.
