A Survey on Guaranteed Availability of Cloud Data with Efficient Cost

Cloud computing is an innovative proficiency in the field of information and expertise. It provides so many things in terms of “As-A-Service” basis. Cloud Computing is the basically visualization of computing as a utility, where customers can tenuously store up their data into the cloud so as to benefit from the on-request services from a collective pool of configurable computing assets. In recent day with increasing the population of data in whole world, the cloud storage space requirement is also increasing rapidly. The main advantage of using cloud storage is, customer can reduce their expenditure for purchasing and maintain the storage area, but they have to use the cloud in optimized manner. In this work, we propose a cost proficient multi-cloud for the data with high data availability. The proposed work contains two principle works; the first is selecting a few reasonable cloud storage providers and a fitting repetition procedure to store information with minimalized monetary cost and guaranteed data availability. The second is setting up a redundant storage method to re-distribute the data among different available data access patterns and cloud pricing models. The proposed technique not just saves around 20 percent of monetary cost additionally shows comprehensive flexibility to information and value changes.
