The growing implementation of cloud computing continues to transform the competitive business landscape in profound and fundamental ways. Cloud hosting delivers IT related services in a manner that is exceptionally suited for progressive companies looking to improve communications, operational efficiency, and top line revenue. Understanding Cloud Hosting Built upon advanced virtualisation technology, the clustered server framework simultaneously channels the data related demands of clients and networks through the linked servers associated with the host. Combining resources in this manner provides clients with exceptional performance and extreme flexibility while removing the bandwidth, storage and space limitations associated with traditional dedicated servers. Within the cloud environment there are several hosting options including the public cloud, the private cloud and the hybrid cloud. While the public cloud is the most visible and cost competitive alternative, private cloud architecture allows enterprise level businesses to prioritise and protect sensitive data and applications. Clustered hosting within a private cloud ensures that data will be protected through security measures designed around the specific requirements of the business. Emerging as a viable solution for small and medium sized companies, the hybrid cloud affords the fixed cost advantages of the public cloud, while selectively retaining IT resources that are best suited for internal control. The hybrid cloud model provides a company with the ability to rapidly scale as demand increases without exposing applications to the security risks associated with the public cloud.

As IT expenses and capital investments begin to shrink, resources can be shifted to other critical revenue generating initiatives. Early Adoption Advantage As the irresistible benefits of cloud hosting continue to attract businesses of all sizes, companies with substantial investments in data centres and dedicated servers will be seriously handicapped from a competitive standpoint. While the sophistication of the cloud evolves, companies committed to large IT departments and massive infrastructure investments will find themselves in an increasingly disadvantageous position. It is during these periods in the business cycle where industry leaders are often replaced by smaller and more nimble enterprises eager to embrace the new technology.
The PaaS method cloud infrastructure has saved companies millions of dollars. One downfall that the PaaS structure has is that every company relies on the PaaS also relies upon the uptime of the vendor providing the service. If a vendor goes down then depending on how bad it is can put each company using their service at a potential financial loss.
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Partitioning and isolation, remains the qualities of server virtualization, by permitting simple and safe server consolidation. Through uniting, the number of physical server, it can be significantly reduced. This one is bringing the advantages of decreased power consumption, floor space, and air conditioning costs. It is necessary to note that it does not change even though the number of physical servers is brought down, to
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
Creating a hybrid cloud which entails taking a strategic approach to cloud adoption by determining what data you want to move to the cloud to avoid unnecessary business disruptions and support customers’ needs.
The scope of this project revolves around the addition of new resources and expansion of existing systems and hardware. This will provide an avenue for a larger entity that has the capability to deliver in an efficient and effective manner. A hybrid model such as cloud technologies will provide the appropriate structure relevant for a large and growing entity as per the proposed merger. A cloud technology can be hosted within and outside the entity for security reasons and maintenance issues. It assumes an important role in terms of costs reduction for the entity given that it results in the reduction of the number of personnel that would be tasked with maintaining and securing the in-house database and systems. Labor and subsequent resources usually result in higher costs of operation within the entity, which in turn hurts the profit margins and possibly the strategic objectives, and goals of the organization (Hallows, 2002).
It would be very difficult to ignore the potential benefits of cloud computing, but it also brings a number of new and worrying risks. Following are typical control requirements or opportunities that businesses may need to consider when considering a move to the cloud
Hybrid cloud is able to provide larger scale of environment. Private cloud and public cloud resource can be used to manage unexpected surges in workload.
As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.
This case study is an analysis of the Chicago Tribunes Server consolidation in which the Chicago Tribune moved its critical applications from several mainframes and older Sun servers to new, dual-site data-center infrastructure based on Sun 15K servers. The Tribune clustered the Sun servers over a 2-mile distance, lighting up a dark-fiber, 1-Gbps link between two data centers. This configuration let the newspaper spread the processing load between the servers while improving redundancy and options for disaster recovery. (Baltzan and Philips, 2009 p 162)

Several types of cloud storage systems have been developed to supporting both personal and business uses. Cloud storage also a model of networked enterprise storage where the data is stored not only in the user's computer, but also in virtualized of storage, which generally hosted by third parties company.
Saas is the model in which an application is hosted as a service to customers who access it via the internet. E.g. Google docs, salesforce.com, CRM, ERP, email, social networking.
There are several reason for the business to adopt cloud computing in order to benefit themselves. The following part is going to describe the two type of business that should adopt to cloud computing.
System design in a data center network provides the tools for addressing the challenges that occur with expansion of data center infrastructure. This includes support for the rapid growth of applications and their data and storage bandwidth, managing and modifying data storage requirements, optimize server-processing resources and access information
