INTRODUCE TO CLOUD COMPUTING Cloud computing, one kind of distributed

computing technology .

The term Cloud Computing derives from the common depiction in most technology architecture diagrams

ARCHITECTURE

CLOUD COMPUTING HISTORY

In the past computers were clustered together to form a single larger computer.

 the cluster management software ensured that the “best” CPU at that time was used to run the code.

GRID COMPUTING Grid computing - expands the techniques of

clustering

Had to be jumped with the move from clustering to grid was data residency

THE NUTS

Storage management

Security provisioning

Data movement

EMC PLANS cloud will monitor data usage, and it

automatically shunts data around to load-balance data requests and internet traffic, being self tuning to automatically react to surges in demand

ADVANTAGES OF CLOUD COMPUTING Cloud computing infrastructures can allow

enterprises to achieve more efficient use of their IT hardware and software investments.

Cloud computing can reduce computerized equipment cost.

Cloud computing can let user use system conveniently, user can use it anyplace and anytime by Internet.

ADVANTAGES OF CLOUD COMPUTING Cloud computing can reduce time and

human resources cost. Cloud computing can apply high-speed

operation in bioscience and linear programming.

Location of infrastructure in areas with lower costs of real estate and electricity.
