The Cloud Computing

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.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

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

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.

On the day of August 31, 2014, nearly 200 private celebrity pictures of various individuals, mostly female and all very personal were posted online. They were taken from personal, private cloud storage systems. They thought their personal information was safe, stored by trusted manufacturing giant Apple Inc. in their iCloud service (Kedmey, 2014). There is no such thing as safe when storing private data in a cloud environment. Individuals and corporations place a great deal of trust in cloud technology. Every day financial information, photos, plans and personal information is poured into virtual accounts stored in places unknown by people unknown. A great and ever-present threat is posed by unscrupulous thieves that stand ready to take advantage of the trust in these accounts. Research suggests the cloud is dangerous to IT security because physical ownership exists outside user control, it is vulnerable to hacking, and has no clearly defined security standards.

Although cloud computing was first introduced in 1950’s, it’s importance of storing digital files online and providing access to it everywhere has become particularly evident over the last decade. Cloud computing can provide access to many daily life services, such as banking, educational and business through the use of mobile phones. Cloud computing solves many daily problems and makes sharing any type of data much easier. Cloud computing shares data through Internet, which makes it easier for anyone to have access to data. Although cloud computing has many advantages, there are also many disadvantages. Many businesses uses cloud computing to get access to various types of data that would benefit them in

Cloud computing is a general term that describes a type of computing that provides services over internet. The roots of cloud computing starts from a concept formulated by J.McCarthy in the 1960, the utility computing or the idea that computing could be organised as a public utility such as water or gas. This concept with many others such as network-centric-architecture and grid-computing can be found under the umbrella of cloud computing (Marinescu, 2013).

Among the most astounding features of cloud computing are that it may offer huge amounts of power with regards to computing and storage and still offer unequalled scalability and elasticity. Furthermore, when considering efficiencies and economies of scale, cloud computing services are not only cheaper, but they also provide a greener way of building and deploying IT services. However, Wang & Laszewski (2008) contend that cloud computing is distinct from other services in several ways.

“The implementation of cloud-based solutions will be subject to various essential elements. These elements are as follows:

Much like a giant office building provides the basic resources that can be tailored to fit several different businesses specific needs, Cloud providers offer customizable IT resources to satisfy an organization’s demands. (Salesforce, 2011) Employing Cloud allows the organization to focus on its primary goals and objectives.

For cloud computing systems to function optimally, the individual components of the network of computing resources must function optimally. Thus, the importance of keeping track of the performance of these components is apparent. In addition to this, the providers of the cloud service need to

Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.

1.Cloud Computing: Cloud computing is defined as the different services such as service, storage and applications are deliver to organization devices and computers through internet. There are mainly three types of clouds they are private public and hybrid and three services are offered by the cloud mainly Software as a service in which user rent access to software application functionally over the internet eg:ltu student mails .,

As information technology continues to improve, applications no longer are limited to being installed locally on a physical computer or server. Cloud computing now allows applications be access via a virtual solution knows as the "cloud". There are many essential characteristics of cloud computing such as on-demand access, pay per use, connectivity, and resource pooling (Durkee, 2010). Users must be able to trust the connectivity when relying on access an application over the internet. Today 's cloud servers are connected to high-speed networks that allow data to flow to the Internet. These high-speed networks improve reliability and expand accessibility. Cloud computing offers
