Abstract
Fault tolerant systems are necessary to be there for distributed databases for data centers or distributed databases requires having fault tolerant system due to the higher data scales supported by current data centers. In a large distributed database usually data resides on servers which are dedicated servers having backups. Therefore, large amount of servers are used for this purpose.
In this paper it is proposed that instead internet can be used as backbone where Infrastructure-as-a-service
(Iaas) service of cloud can be used for storage servers. The advantage of this will be that storage location is abstracted and database can be accessed from anywhere. However while the storage allocation is abstracted it also brings in performance concerns in a multi tenant cloud environment where by most of the cloud consumers are geographically dispersed. Recent large Web applications make heavy use of distributed storage solutions in order to be able to scale up. Here we propose that static distributed database is spread over cloud making database dynamic.
Keywords-distributed database; cloud; geo-redundancy; API
I INTRODUCTION
Data storage is diverse at different remote locations in case of distributed databases. Dedicated servers are used to store these databases; therefore many servers are needed by companies to store their large databases. Those servers were static i.e. their

    A main server that is big enough to route files in it for storage can help a computer and website run faster. Just as an external hard drive can store data on it away from a computer to free up the main hard drive can help a computer run faster. Cloud storage operates in the same concept, instead of having a hard drive, there is a huge server with a lot of storage. In this paper, the company that I have chosen has issues with server space and need a newer solution to developing a better service to the company and its production facilities. I will explain what it will take to boost service speed and help the company to ship products out faster with just a solution in server space.…

    Cis 500- Cloud Computing

    Technology has taken great leaps of advancement. Some of the new technology that companies and consumers are taking advantage of to store and process data is cloud computing. Cloud computing was derived from virtualization. Virtualization allows companies to separate business applications from hardware. Doing this gives the company the capability of assigning applications as needed. The option to manage applications is a great benefit to companies. Resulting from the virtualization error, cloud computing has emerged to provide flexible IT infrastructures. This has not only enhanced the options companies now have, but it is also proven to be more cost efficient. This has increasingly become a preferred method of companies and consumers alike.

    Cloud Database

    The cloud computing is the next generation of the computing, its advantages, advancements and research are a plenty. In recent years, the term “cloud computing” has been critical in the world of IT. Cloud computing, or the use of internet-based technologies to conduct business, is recognized as an important area for IT innovation and investment (Armbrust et al., 2010; Goscinski and Brock, 2010; Tuncay, 2010). Cloud computing has spread out through the main areas related to information systems (IS) and technologies, such as operating systems, application software, and technological solutions for firms (Armbrust et al., 2010). The promise of cloud computing is to deliver all the functionality of existing information technology services even as it dramatically reduces the upfront costs of computing that deter many organizations from deploying many cutting-edge IT services (J.Staten, 2009). Cloud computing represents a convergence of two major trends in information technology — (a) IT efficiency, whereby the power of modern computers is utilized more efficiently through highly scalable hardware and software resources and (b) business agility, whereby IT can be used as a competitive tool through rapid deployment, parallel batch processing, use of compute-intensive business analytics and mobile interactive applications that respond in real time to user requirements (W.Kim, 2009). The impetus for change right now is seen predominantly from a costs perspective, as organizations increasingly discover that their substantial capital investments in information technology are often grossly underutilized (Sean Marston et al., 2010).…
