Regulation on Cloud to Protect User Privacy

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure. [1] Example: Google application engine, Software as a Service (SaaS) is

Cloud computing includes three service models, it is important to differentiate between them because the service provided is not the same and they do not address the same users. The three service models are:

Cloud computing enables businesses to deploy or subscribe to services as it needs them. A cloud features self-service, broad network access, centralized shared resources, and measurement of service usage. There are three widely accepted types of cloud service models. They are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each serves a different purpose and business may choose to use just one, two, or even all three of the cloud types simultaneously as the needed.

Cloud computing is a fairly new technology; it is separated into three separate categories. The first is Infrastructure as a Service (IaaS) this service is mainly used by companies to cut the cost of buying computer hardware such as servers , they also save on maintenance cost since the virtual servers is maintained by the company that rents them [1]. The second category is Software as a Service (SaaS) this service deals with providing software which is usually rented, this allows users to have multiple users whereas normal software limits the amount of users [1]. The last category Platform as a Service (PaaS) is used as a tool to develop software [1]. All these services offered by Cloud Computing are done virtually where you access

In a virtu¬alized environment , lease compute, stor¬age, network, and other resources are provided to user by the IaaS model. underlying cloud infrastructure has not been manage by the user but user has control over the OS, storage, deployed applications, and possibly certain network¬ing components.

There are different types of cloud computing services available on the market which falls into one of the following categories.

The popularity of mobile system with the headway in engineering, with the increment of Internet utilization, comprehensively reinvent the old idea of network computing system, to the new buzzword "Cloud computing". Cloud computing is a link way to the usage of Cloud which process by transmitting and receiving files in utilizing Internet. Most systems uses either of the three major models of cloud computing services on the market, which are software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS).

The main purpose of the cloud technology from software perspective is to provide private and hybrid cloud, big data analytics, file storage, disaster recovery, and important backup. Generally, cloud providers offer services according to their models. There are mainly three standard models are available according to National Institute of Standards and Technology, which are Infrastructure as a Service (servers that allows user to store data and access the services), Platform as a Service (develop the software for the user to access cloud technology), and Software as a Service (graphical view of application, from where user can access cloud servers)

Software and Platform as a Service describe the business model of users logging into a centralized hub to access their software products. Users open their files and software only while online, using only their web browser and passwords. It is similar to the idea of mainframe terminals, but cloud computing involves a much larger "cloud" (network) of processing computers at the center.

The following provides an overview of the three cloud service models defined by NIST together with some real world examples for each:

The three deliver methods of cloud computing/storage is software as a service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). The service provides on-demand pay per use and is independent of a platform.

These private environments are made accessible via the Internet. Cloud computing provides services such as software (applications), platforms and infrastructures with a subscription-based in a pay-as-you-go model. These services are generally referred as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

Software as a Service is where your application and data are both in the same place. For e.g. Google Docs, Salesforce, etc. Any service which has its application and data in the same location and which provides you APIs with which you can interact. For e.g. Let’s say your

This cloud architecture allows the cloud provider to create a computing platform that consist of components such as hardware, servers, routers, storage, and other networking modules. The model follows the pay as you model where each user takes the services offered and pays for what they use or consume. Users can deploy and run any software, which comprise Operation Systems, applications. The cloud provider is responsible for managing the core cloud infrastructure for which users deployed applications or operating environment. Examples of this cloud computing model include Amazon Elastic Compute Cloud (Amazon EC2) which is an Iaas model that facilitates scalable compute volume, on-demand, in the cloud. It actually allows users make use of a plethora of Amazon 's infrastructure with no up-front investments. Amazon EC2 decreases the clock needed to get hold of and boot latest server instances and permit users to immediately scale space – equally up and down as their computing needs vary.
