The effectiveness of cloud databases

‘Utility computing’ was the concept introduced by John McCarthy in 1961 in a speech given at MIT. He proposed that sharing the computing power on a time-sharing basis will help grow business of ‘providing computing power as an utility’ and this was the inception of the cloud computing. Cloud computing can deliver the best to the end users either through the private, public or hybrid cloud infrastructures. As the databases are of significance importance, it is a mandate that they ought to be designed compatible to the rising cloud technology. Cloud computing has changed the face of the IT industry. But in the current scenario there are many database issues that are not addressed. With tremendous data growth, the need for the paradigm shift in the technology to be used to store, manage and retrieve data is awaited. Databases have changed from file storages to relational databases and further transformed to today's cloud databases. Still the need to process the query efficiently without losing the data privacy had been the topmost priority. The resource optimization and query dynamism are the major unchanged aspects in this changing scenario. The timing constraints on the query execution could be leisurely, indefinite, urgent or instantaneous. In almost all the scenarios, the effective storage, elastic manipulation and efficient data retrieval is the key.
