Understanding cloud computing A good example of cloud computing is
Google Docs. You don’t need to buy a CD-ROM and
install it in your computer. Just access to Google’s server via
Internet. Write and save files in Google’s server. It’s like borrowing Google’s server and
application.

Traditional service is like building a house.
Cloud computing is like renting an apartment.

Why is cloud computing cheaper? Servers are not fully utilized. Average utilization rate is below 10%.

Virtualization
10%
“Virtualization” has made it possible to use this portion for other purposes.

Economies of scale
By aggregation, hourly demand levels off.
Cloud providers achieve efficiency by deploying large-scale servers.

Major providers
Amazon, Rackspace, Microsoft, Google, Salesforce, IBM, etc.
Some provide application services in addition to lending servers (called SaaS).

Public cloud versus private cloud
Public cloudStandard cloud model explained
above.
Private cloudOperated solely for a single
organization over the Intranet.Not connected to the Internet. So it’s
Secure.

Private cloud (cont.)Companies have to buy, build, and
manage servers by themselves.Economies of scale decrease.

US Government
Federal cloud computing strategy (2011) Federal Government’s IT spending is
currently $80 billion. $20 billion is a potential target for migration to cloud computing.
Federal Data Center Consolidation Initiative (2010) Out of current 2,100 data centers, a
minimum of 800 should be eliminated by 2015.

Japanese Government
Kasumigaseki Cloud Project Private cloud model. Basically consolidate all servers. Consolidate as many
operating systems as possible.
Consolidate applications that have similar features across ministries.
