Explanation
The best option to provide the desired service with the lowest cost and downtime after initial stress testing showed that a platform performed well with the specification of a single 32 vCPU node is to use three to six 8 vCPU nodes autoscaling group. An autoscaling group is a feature that allows dynamically adjusting the number of instances or nodes in a cluster based on the demand or load. This option will provide high availability, scalability, and performance for the service, while also optimizing the cost and resource utilization by adding or removing nodes as needed.
