I'm trying to create an extremely basic model of what a setup in Amazon Web Services might look like translated over to an on-premises cloud. I'm aware that Amazon is quite SAN-reliant, and pretty complex, but please bear with me on this simple model :)
How do these two setups compare? Is one more powerful than the other, and is there a good rule of thumb for equivalence?
AWS: m3.2xlarge has 8 vCPUs at 2.1GHz, 30GiB RAM, and 2x80 SSD drives.
Physical Rack Server: 8 physical CPUs at 2.2GHz, 32GB RAM, 500GB hard drive.
Ideally I'd love to know something like "one AWS instance like this is roughly half as powerful as the physical version."
