3.1 Overview of Cloud Computing Architectures
We purposed a framework in cloud computing system five layers:
application, software environment, software Infrastructure, software kernel,
and hardware are available. Hardware layer the actual physical component of the
system is available at the bottom of the cloud stack. Different companies have
devised system on subleasing the hardware in this layer as service. Cloud
application layer the interface of the cloud to the common computer user is at
the top of the stack through web browser and thin computing terminals. Five subsections of the layers showing their
characteristics and limitation are under. The first layer of the cloud
application is PAAS. This is the clearest layer to the end user of the cloud.
The users access the services provided by the layer through web portals on fee
basics. Many users have been attracted by it as it reduces the Burdon of
software maintains etc. this in turn reduce the limits on hardware needs at the
user end. Allowing them to get best performance to some of their CPU-intensive
workloads.Curtailing huge capital investment on machines. For cloud application
providers this model simplifies their work of upgrading and testing the code.
Protecting their intellectual property.In this model configuration and testing
of the application is less complex as the use of environment becomes limited.

regrades the provider profit this model support him with a continues flow of
revenue becoming more profitable in future. Yahoo pig a high level language to
enable processing of huge files on Hadhop environment may be seen as open-source use of the cloud
platform layer. It helps the process of the development of cloud application.
