Cloud Computing Is An Internet Based Technology Essay

Business owners use three types of cloud service, public, private, and hybrid these clouds store their data and provide them with services. The benefits of these clouds are endless, additionally, they saves businesses time and money, promoting innovation, enhancing productivity, and improving communication while cloud hosting accelerate information sharing, like email, application hosting, web-based phone, and data storage (Griffith, 2013).

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 innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of

Hybrid cloud is a mix of both private and public from different providers that offers benefits of multiple deployment models. Extends capability of a cloud service.

When a cloud service provider connected both public and private cloud’s infrastructure, it will be called hybrid cloud, which let an organization to arrange workload between two environments that its deployments need compatibility among the software that both private and public clouds using.

These administrations are extensively separated into three classifications: Infrastructure-as-a-Service (Iaas), Platform-as-a-Service (Paas) and Software-as-a-Service (Saas). Cloud computing was named motivated by the cloud image that is frequently used over the Internet through diagrams or flowcharts. Input data is analysed, collected and stored in one big online server which an authorized particular person can get access to. Margaret Rouse (December 2010). Moreover, four deployment models that have been used to deliver cloud services are private, public, community and hybrid. Private cloud is used by single organization to be able to

The word "cloud" is used to represent the internet and other communications systems. Cloud computing is the result of an evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing in the past, telecommunications companies mainly gave simply dedicated, point-to-point data circuits to their users. Starting from the 1990's, virtual private network services was included in their contributions. It made the telecommunication companies offer equally improved services whereby cutting down on cost as well as using resources effectively.

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

of a Public cloud is that they may be larger than an enterprises cloud, thus providing the

Private Cloud :- In this form of deployment a designated service provider will operate a cloud infrastructure for a private entity. The two variants in the private cloud are on premise private cloud and externally hosted private cloud(or off premise private cloud).

Public cloud: cloud computing model whereby a cloud service provider provision resources over the internet such as software and data storage, which clients can access through the web browser.

Cloud computing is a practice of storing, collecting and sharing data and resources through web-based tools. It connects many computers together and forms a bigger computer. The biggest characteristic of cloud technology is flexibility. This refers to the ability of system adapting and scale to change in workload. Cloud computing can automatically provision and deprovision information to ensure it satisfies the latest resource demands (Interoute, What is Cloud Computing).

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).

The organisation which does not give rights to the trusted third party to govern the management of the clouds because of various security limitations will try to implement this kind of cloud. Hybrid cloud is the combination of the public cloud and private cloud the data transfer takes place without creating any effect to both of the clouds, it allows the computing needs to deal with the clouds and the cost changes according to the resource. The advantages of hybrid cloud are its data storage , bandwidth flexibility to the business sector. Hybrid cloud which is designed properly is used for security services for customers payment etc.. In this cloud the most secured and sensitive data is placed on small private cloud and the

In today’s age and time more services are moving to the cloud. A lot of people do not know what the cloud is, as the main variations are the public cloud, public/private cloud and the private cloud. The pubic cloud security is what we are going to be focusing on but there will be references to the private cloud. A quick definition of the public cloud is basically like an apartment or condo where multiple tenants share a huge building but have there on private spaces inside that building. An example of the public cloud for business is Amazon Web Services (4), Microsoft Azure (3), Office 365 (5), Google Cloud Hosting (6), and Box.com (7). A private cloud on the other hand is something you host internal inside your company to do similar services that is a private cloud. If you have remote log in like an SSLVPN connection you technically have a private cloud even with a file server or you could make it a little more user friendly and bypass the SSLVPN with something like Owncloud (8), which is similar to a private Dropbox (9) or Box.com (7).
