Pawan Kumar Singh, Nirayo Hailu, Vinod Chandran · 2014
Unlike last countless years, the present era has no dependency on relational data base due to the rise of technological changes such as web based applications has replaced the stand alone applications , distributed servers has replaced the normal dedicated servers. A giant imagination gets converted into reality in the form of cloud computing next to World Wide Web. Cloud databases are becoming popular and used for data exhaustive applications as data mining, warehousing and intelligences. This paper give a review on an architecture of shared disk database for cloud computing. The database architecture called shared-disk is ideal for cloud databases, which eliminates the need to partition data. It allows the clusters of low-cost servers to use a single assortment of data. It is typically served up by a Network Attached Storage (NAS) or Storage Area Network (SAN). All of the data available to all the servers, there are no partitioning of data is required. For example if we are using two servers and query takes .60 seconds and now we can dynamically add another server, the same query might take .30 seconds. Thus elastic scalability is supported by this type of database.
