For Amazon EC2 Container Service, providing the ability for users to select specific processor, memory, disk, and interface types might be an ideal feature. But, the practicality of offering all possible physical combinations is nearly impossible due to the underlying physical machines.

Customers generally comprehend this limitation, as even in their own data centers, exact physical machine requirements are often a result of a combination of factors such as price, availability, and new machine generations.
