of Cloud Computing——–
Cloud computing is a technology which trends in the market
for coming up future technologies. It has turned to technology to support
business. Cloud computing
is a set of services. Presenting services in Internet by hosting their services
to internet is a new paradigm. Cloud computing, hardware or software need to implement any kind of
infrastructure. This paper is cloud and help customers for payment of benefits, flexibility,
and scalability, without nevertheless, computing Steps virtual platform
providing cloud and You can be taken to prevent security breaches
describes facing security problems in computing. Is essential for
companies to understand the risks associated with the cloud
compute. Security cloud and major problem of computing is facing problems. Data
protection and cloud examining the utilization of cloud by vendors and security
issues. Cloud computing is a detailed analysis of the description,
challenges, and security issues in the following article.
Cloud Used to represent diagrams and flow charts, Internet
computing more if the symbol was inspired by the cloud. Important components
of 1 of
independence where known virtualization and cloud computing, rapid elasticity,
and resources pooling. Such as in will be used to provide a variety of
characteristics. It is a way to improve business functions, without having
to invest in new infrastructure and investment. We the information technology (IT) of high speed growth in the field area to see the cloud computing a tremendous growth from
the business concept.
A powerful and rapid development of the process of
storing the computer resources are cheaper technology. New trends have
emerged among the company, the cloud in the
field of computing and information technology in recent years have affected a
great deal. Companies offering cloud technologies, Google, Amazon,
Microsoft ( Zheng c.) Is.
Cloud computing, Internet -Based computing 1 one store and access data and programs via the
Internet. Customers computing as a service is one of
the resources that provide the fastest way. Cloud computing renting
customer service online or not to install them. Cloud architecture identified solutions 4 there are
three different deployment models.
· Private cloud: private sector organizations and organizations using
or on site or off, or possibly third- Cloud is operated by the party Infrastructure.
· Public cloud: cloud can be used by the general public infrastructure. Usually Microsoft
Amazon or Google of such enterprises is owned by them.
· Community cloud: cloud shared tissue of some specific requirements or
concerns shared by Is the
· Hybrid cloud: cloud infrastructure the above probability of applications and data to
enable 3 One is in
the combination of deployment model.
Cloud & Computing architecture
Cloud Computing 3 has three main models. Other services the
· Software as a service (SaaS),
· Infrastructure as a service (IaaS)
· Platform as a service (PaaS):
Service (SaaS) As a software: Top layers of cloud computing
SaaS The SaaS Are available to customers through a network, and
executed on a server provided by the provider Web- -Based / On – Demand / Host Also referred to as software. It delivery model
or platform to expand applications via the Internet as a service, and provides
consumers with the ability to use the provider’s application. Access to
this application, security, availability, and performance such as email providers given the thin clients Interface through a variety of clients you can access from the device. This software data perform tasks related to storage, transfer and backup,
very low cost (Beer, Hocenski Z Popovic K. V.) In business software provides a service. “SaaS of
certain characteristics is as follows.
· Multi Tennant, Architecture: Common code base and
infrastructure to maintain. Useful for rapid innovation, vendor
development and save time it is.
· Easy customization: application is affecting the common ground that are
customized according to customer. All of the customizations maintain
during the upgrade of a unique low customer risk and adaptation costs for all
· SaaS use consumer Web: SaaS application web interface, Amazon and Yahoo On is very similar. Click and is easy to
customize with point.
· SaaS of trends: many
organizations are Sip (SaaS integration platform) of actively developing. Software adaptation is
also called the third wave as a platform for critical applications (sales force).”
Service (IaaS) As the intermediate layer of cloud computing
Infrastructure Service (IaaS) as a virtualized hardware, computing is a
layer of single tenants are also referred to as infrastructure. IaaS the software, hardware, and storage servers and other infrastructure, Hosting component, on behalf of the user third- party providers are included. Providing virtual space,
network connectivity and bandwidth are included IP address and load balancer and consumers to expand the Application
and operating you can run software that contains the
system. Network cloud provider Will provide the financial flexibility and
greatly minimize any huge investment and many data managed Will be distributed in the Center. Company
performs without any kind of hardware features it provides. Applications
that are deployed in the consumer and operating systems (Dimi trios Z., Dimi trios and l.) Can be controlled. Following the National Agency
for property as follows.
· Scalable: it can be to adjust the on-demand
scalability. Ideal for temporary, so that changing any experiment or
estimated workload (Margaret.).
· No single point of failure: number of hardware a wide
range of services is unchanged if there is any failure due to resource and
· Location independence: all 1 one is must be an active Internet connection from
anywhere to access cloud Security Protocol “(IaaS is).
Service (PaaS) As a platform: Cloud Layer in computing
PaaS, Provides the environment for the Platform stands as a
service, platform, and developers to build applications and services that you
can deploy cloud base on. Software application
uses the tools provided by your provider, you can create. Customers can
subscribe to the of has to choose from that meet the requirements.
is always upgraded on the existing and additional features. PaaS offers software and web developer can get companies to develop their own
internal software. The consumer cloud infrastructure (Dimi trios Z., Dimi trios and) Take
advantage of if you are not using the service for controlling, as the
developer’s workstation can be.
Features are as follows.
· Investment in the physical infrastructure: Can be used as a platform for creating software and
applications do not have to buy all the infrastructure can install or
rent. Reduces unnecessary costs to be able to service customers, they need
· Flexible it according to the requirements of the tools and
features Give control back to the customer on a platform installed.
· Adaptation: can change based on the situation and made easy to
· Virtual team: across the various locations of the developers, that
can be used together in the same application” (What is PaaS)
