Information Technology World Cloud Computing

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

According to Lawrence Shawa, "a number of organizations I have spoken to have expressed concern about how secure their data is that is hosted in the cloud. There is sense of control that is taken from them making the organizations feel vulnerable" (Collection 2:1) Companies naturally feel a strong sense of obligation to protect their customers. Additionally, they may lose business if they have a reputation for compromising customer security.

Question 1. What is the most appropriate Cloud Deployment model (or combination) for BPI (Public, Private, Community, or Hybrid)?

Services such as, data storage and security, are provided by cloud computing over the internet. In cloud computing, users can pay for what they consume (Bisong & Rahman, An Overview of the Securtiy Concerns in Enterprise Cloud Computing, 2011). Cloud computing is an emerging information technology, which can make it easier for the users to manage their data. Cloud computing allows businesses to expand as new cloud-based models are being discussed and implemented as solutions (Bamiah & Brohi, 2011).

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

The economic case for cloud computing has gained widespread acceptance. Cloud computing providers can build large datacenters at low cost due to their expertise in organizing and provisioning computational resources. The economies of scale increase revenue for cloud providers and lower costs for cloud users. The resulting on-demand model of computing allows providers to achieve better resource utilization through statistical multiplexing, and enables users to avoid the costs of resource over-provisioning through dynamic scaling [12, 2]. At the same time, security has emerged as arguably the most significant barrier to faster and more widespread adoption of cloud computing. This view originates from perspectives as diverse as academia researchers [12], industry decision makers [35], and gov-

Cloud computing is an emerging computing technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Cloud computing is broken down into three segments: "applications," "platforms," and "infrastructure." Each segment serves a different purpose and offers different products for businesses and individuals around the world. In June 2009, a study conducted by VersionOne found that 41% of senior IT professionals actually don 't know what

of organization, are discussed. Characteristics of cloud computing discussed to get idea what the cloud computing is all about using. In addition to that, deployment model of cloud computing is discussed in greater detail to explain cloud computing can be used as public, private or hybrid type. Based on service delivery cloud computing divided into three types Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are explained further in this section.

Cloud computing is a technology that provides practice of applications and services over a remote servers, which means you can use a remote server to store, process and manage your data rather than buying your own server. Cloud computing is a rising technology now a day’s every big organizations are adopting cloud in their services due to its vast benefits and also it has numerous potential profits to the associations by creating a service which is very simple and easy to maintain. By introducing cloud service in the organization will simplify many issues related to the security, computer networks and other services which are served online.

CLOUD Computing set up unavoidable, advantageous, on request arrange access to a mutual pool of configurable computing assets that can be quickly arranged and discharged with basic endeavors for administration or specialist organization association. Its primary target is to convey quick, secure, helpful information stockpiling and net computing administration, with all computing assets, imagine as administrations and conveyed over the Internet. Various computing ideas and advances are joined in Cloud Computing to fulfill the computing needs of clients, it gives normal business applications online through web programs, while their information and programmings are put away on the servers.

Cloud computing security is that the combination of control-based technologies like network security, pc security, info security and policies designed to bind the restrictive compliance rules. it 's primarily wont to shield info, knowledge applications and infrastructure related to cloud computing use. The zoom in field of “cloud computing” has multiplied severe security issues like securing knowledge, and examining the use of cloud by the cloud computing vendors. the most plan is to spot the foremost dangerous security threats in cloud

The Cloud Computing refers to “Computing over the Internet”.It came from Grid,utility and web services.It is a combination of network,servers,storage ,operating system and virtualization technologies to form a shared infrastructure that enables web-based value added services.End users access cloud-based applications through a web browser or a light-weight desktop or mobile application.The business software and user 's data are stored on servers at a remote location. The cloud model comprises five

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)

Cloud Computing today has really reached in cloud 9 position.It is ever rising field in software and hardware world.Cloud Computing provides the utilities remotely.The utility it provides can be remote Operating System or it can be storage space or any such software and hardware utility.The user of cloud utilizes this resources remotely without having them in his own local machine.The local machines cannot store huge amount of data and process it,so by using cloud user can store its data on cloud for further processing.Cloud Computing principles are the reason why cloud is gaining huge success and popularity.

This technology named as Cloud Technology or Cloud Computing was just a buzzword during the early 2010 but became more prominent and was widely adopted by 2012.Internet in other terms can be termed as a “cloud”. There are two words that define Cloud computing the most: Web Applications. Any organization using huge clusters of computers which require high performance through the host of services available use cloud computing. [1, 2]
