Abstract:Cloud computing has emerged as a most

important technological breakthrough for small to

medium scale enterprises and software users who

are looking for dynamic scalability at a low or zero

initial investment. This paper offer a brief view on

cloud services; evolution of cloud computing; and

an outline of the opportunities cloud services bring

to the enterprise. Also, proposing one secured

architecture for cloud computing using M! and

A"# algorithm in cloud data server.

Keywords: Cloud computing, architecture, security,

models, services.

The (nternet has e-perienced massive increase in thelast decade, and hundreds of millions of users no

depend on it for dail nes, entertainment and

commerce. Cloud Computing is a ne processing

method in hich computer processing is performed in

the internet called /Cloud0 meaning that the user need

not concern ith the processing details. Cloud

computing is a general term for anthing that involves

delivering hosted services over the (nternet. Cloud is an

environment here properl secured, highl scalale,

and elastic services can e easil consumed over the

(nternet on an asneeded asis. (n Cloud computing, theprivac and securit concerns ill differ eteen

consumers using a pulic cloud application, a medium

si3ed enterprise using a customi3ed suite of usiness

applications on a cloud platform. The shift of each

categor of user to cloud sstems rings a different

pac4age of enefits and ris4s.

According to the 5ua617 et al. Cloud Computing

is defined as8 /a type of para!!e! and distri"uted systemconsistin of a co!!ection of interconnected and

virtua!i$ed computer that are dynamica!!y provisioned

and presented as one or more unified computin

referring to the comination of computer resources

common goal. The grid can e thought of as a

? Uti!ity Computin% tilit Computing is the

pac4aging of computing resources, such as

computation, storage and services, as a metered service

similar to a traditional pulic utilit Bsuch as electricit,ater, natural gas, or telephone netor4?. This model

has the advantage of a lo or no initial cost to acuire

computer resources: instead, computational resources

After all these computing process, Cloud computing

emerged and this has all these technologies or4ing
