Breakdown of Amazon's cloud based services

Good basic overview of Amazon's cloud based services and how they interrelate. Graphical representation of:

1. Infrastructure (compute, storage, network, database); includes global physical infrastructure
2. Platform (parallel processing, payments, content delivery, workforce, messaing, email)
3. Cross service features (authetication and autorization, monitoring, deployment and automation)

Jinesh also explained how ISPs can resell AWS instances with margin using DevPay. Wondering what the developer/channel/spot market dynamics will be.

Wonder how many of the services are home grown vs. COTS white labeled. Anyone know?
