Template mismatch

Steps to Reproduce:

1. Create a hardware profile with below configuration
    memory(MB)      1024
    cpu count       2
    storage(GB)     200
    architecture
    label     x86_64
     
Expected Results:

The close match from aws template definition for the above configuration is m1.large.
     
Actual Results:
    Aeolus displays c1.xlarge as the close match(PFA: Template mismatch.png)
     
Additional info:
    cost of m1.large:$0.20 per hour(for Linux usage)
    cost of c1.xlarge:$0.40 per hour(for Linux usage)
     
Conclusion:

    It seems that aeolus is choosing the close match based on RAM value.  It will be really appreciated, if aeolus would consider all the possible parameters (which includes the cost also) to choose the best possible match, this will benefit the end customer to a greater extent.
