Does this include:
- rack space monthly
- any service contracts
- cost of physically mounting, learning, and configuring the bespoke system
- power costs
- cost to pay an senior admin to be available to support it
- cost to have that admin come in on a weekend to a data center at 3AM to replace failed disk or debug other issues vs. clicking links in AWS from home
...and how does Cisco know what the cost of S3 storage is going to be even 6 mo from now? That's the best part of AWS - commodity pricing goes down automatically, while the cost of skilled labor to support enterprise capital metal always goes up.
