Problem with Grid Computing / Parallel Computing
High admin cost
Difficult to use from lay users perspective
Users still have to be aware of the physical hardware layer - #
of nodes, etc.
Users are transparent to the physical hardware through
It scale-in / scale-out based on pre-defined usage criteria.
Administration cost is decreased.
IT resources are better utilized.

Cost Structure of Public Cloud Service
• 2 Points to Note:
Initial fixed cost is switched from users to service providers
As users become increasingly rely on server access, it is cheaper
for users to implement their own IT infrastructure

Why AMZN provides Public Cloud Services?
From service providers’ viewpoints, it has high initial
fixed cost, so why are they still doing it?
The players are: Google, Amazon, IBM
They have already built a hugh IT infrastructure to handle their
Internally, AMZN want to utilize their IT resources to save their
Cloud Service solves their own problem. And they could take
advantage of their existing IT infrastructure by make business
use of it
=> Public Cloud Services is born
