The Cloud Of Cloud Computing

Cloud because of its wide range of applications it allows users to store data their data remotely in the cloud and enjoy the on-demand high quality cloud applications and reveal burden from the local storage, cost and maintenance. In this according to the user’s perspective, including both individuals (private) and enterprises like companies appealing the cloud benefits by storing data remotely into the cloud in a flexible on-demand manner and relief of the burden of storage management along with this he/she can also enjoy the universal data access which dependent geographical locations and avoidance of the capital expenditure, software, hardware and personnel management and maintenances and so on.

The purpose of this report is to provide decision makers with introductory information on cloud computing technologies that will facilitate their understanding of the primary concepts associated with the cloud computing paradigm and contribute to making informed decisions with regard to issues related to cloud adoption.

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources

The National Institute of Standards and Technology defines cloud computing as a model that allows convenient, on-demand network access to a pool of configurable computing resources. These resources may consist of storage, networks, servers, applications, services and so forth that can be quickly provisioned and put into service while requiring a minimum of management effort or interaction by the service provider (Mell & Grance, 2011).

Cloud computing has been defined by NIST as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or cloud provider interaction. Cloud computing can be considered a new computing paradigm insofar as it allows the utilization of a computing infrastructure at one or more levels of abstraction, as an on-demand service made available over the Internet or other computer network.

“Cloud Computing” is a buzzword that the IT industry has been talking about since the past few years. The future of computing is distributed and off-premise where remote servers handle terabytes of data every day. From both technical and social viewpoint, the concept of distributed data centers maintained by “server” companies somewhat dates back to 1990s where grid computing was actively thought upon as an IT requirement. Cloud Computing’s primary aim is provision of IT as-a-service to the cloud users on a utility-based delivery model envisioning greater storage availability, flexibility and scalability of IT systems.

Cloud Computing, also known as ‘on-demand-computing’. It is a computing that based on internet to share resources, information, and data with other devices on-demand. It is a model that enabled everywhere, computing resources such as servers, networks, applications and storages that are configurable can be shared once demand with access and provision rapidly and released with minimum effort of management, and different services are handed through Internet to the computer of organization. Cloud Computing depend on sharing computing resources instead of using personal devices or local servers to handle applications.

Cloud computing provides various services to its users through internet using a pay as per usage plan giving users the freedom to use just exactly what they want and change their requirements accordingly based on their usage. Hence avoiding the huge costs that incur to setup and monitor a server system which has a limited scalability. Even though Cloud Service

Cloud computing is a shared resource that holds valuable data from masses of people and organisations and is therefore an easy target for hackers. Security within cloud computing involves a set of control-based technologies, polices, processes and standards to protect information, data applications and infrastructures related to cloud computing usage. Security within this area addresses the physical and logical security issues across the different service models as well as how these services are delivered ie.via the public, private or hybrid model. There are many points of entry for an attacker in the cloud environment and people are more exposed to data breaches than they think e.g. using an insecure website on your mobile phone or if a database administrator shares a password, personal details can be accessed.

The scarcity of computing resources can lead to slowdown or delay in processing job requests. In some cases, it leads to the rejection of job request. However, the emergence of Cloud computing gives the illusion of infinite computing resources. These resources are made available on demand and can be provisioned rapidly and automatically in any amount of quantity to process users’ job requests. In the Cloud, it is possible to add up resources for provisioning when there is an increase in application load (Scale up). On the other hand, when there is a decrease in application load, resources can be released. (Scale down). This feature of the Cloud that dynamically scales the amount of the resources it provides to clients as their workloads increase or decrease is called elasticity [41]. In this work, the number of resources in the private Cloud are considered to be static (not elastic). However, based on the characteristics of the incoming jobs of users, extra public Cloud compute resources can be rented or released [1][42].

Mainly Cloud computing word is related to the concepts of the storage and the accessing of the data that was over the internet. With the usage of this cloud computing the growth in the business has been increased over the decade very high. On the client side there is no need to maintain the infrastructure and also there are many advantages of this cloud computing technology. By the usage of this model the cost will be saved and also the time will be. Service providers of the cloud computing will provide the different types of the delivery models and the deployment models and each model has its own services and features. Out of all the deployment models infrastructure as a service model is the best as it was offering its services based up on the pay per usage by the user and out of all the delivery models hybrid model is the best as it was having all the benefits of both the public and the private.

Cloud computing is an expansive scale disseminated computing worldview driven by economies of scale, in which a pool of disconnected, virtualized, powerfully adaptable, exceptionally accessible, and configurable and reconfigurable computing resources can be immediately provisioned and released with irrelevant organization effort in the data centers. Moving data into the cloud offers magnificent solace to customers since they don 't have to consider the complexities of direct hardware organization. The pioneer of cloud computing dealers, Amazon Essential Storage Service (S3), and Amazon Flexible Figure Cloud (EC2) [2] are both definitely comprehended representations. While these electronic online services do give enormous measures of storage space and versatile computing resources, this computing stage shift, then again, is discarding the commitment of adjacent machines for data support meanwhile. Accordingly, customers are vulnerable before their cloud service provider (CSP) for the openness and dependability of their data.
