Let me answer your question.
Just for context, here’s the rationale that’s given for the option: Use EC2 Dedicated Instances with elastic inference accelerator
“..is incorrect because these are EC2 instances that run in a VPC on hardware that is dedicated to a single customer and are physically isolated at the host hardware level from instances that belong to other AWS accounts. It is not used for reducing latency. In addition, elastic inference accelerators only enable customers to attach low-cost GPU-powered acceleration to Amazon EC2, Amazon SageMaker instances and other resources”
EC2 Dedicated Instance indeed isolates your instances at the host hardware level. However, it doesn’t guarantee that instances will always launch on the same physical server. What it does ensure is that the underlying hardware your instance runs on is exclusively yours and not shared with other customers. Therefore, there may be situations where your instances are not colocated and are hosted on separate hardware. For that reason, the use of EC2 Dedicated Instances is incorrect.
Let me know if this helps.
