Understanding cloud computing

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.

4

Traditional service is like building a house.

Cloud computing is like renting an apartment.

5

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.

7

Economies of scale

By aggregation, hourly demand levels off.

Cloud providers achieve efficiency by deploying large-scale servers.

8

Characteristics of cloud computing Speedy service 

Low cost

Flexibility

Security concerns

9

Major providers

Amazon, Rackspace, Microsoft, Google, Salesforce, IBM, etc.

Some provide application services in addition to lending servers (called SaaS).

10

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.

11

Private cloud (cont.)Companies have to buy, build, and

manage servers by themselves.Economies of scale decrease.

Cloud computing and the government

13

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.
