## SHEDS:A Simple and Secure Cost Efficient Data Storage in Heterogeneous Multiple Cloud

Multi-cloud | HomePage

This paper proposes a novel data hosting scheme (named SHEDS) which integrates two key functions desired. The first is selecting several suitable clouds and an appropriate redundancy strategy to store data with minimized monetary cost and guaranteed availability. The second is triggering a transition process to re-distribute data according to the variations of data access pattern and pricing of clouds. We evaluate the performance of SHEDS using both trace-driven simulations and prototype experiments. .

The results show that compared with the major existing schemes, SHEDS not only saves around 20% of monetary cost but also exhibits sound adaptability to data and price adjustments

## Multi-cloud data hosting

Multi-cloud data hosting received wide ttention from researchers, customers, and . The basic principle of multi-cloud (data hosting) is distribute data across multiple clouds to gain enhanced redundancy and prevent the vendor lock-in risk, as shownThe potential prevalence of multi-cloud is illustrated in three
folds. First, there have been a few researches conducted on multi-cloud. DepSky guarantees data availability and security on multiple clouds.

## Vendor lock-in risk

Facing numerous cloud vendors as well as their heterogenous performances/policies, customers may be perplexed with which cloud(s) are suitable for storing their data and what hosting strategy is cheaper.

The general status quo is that customers usually put their data into a single cloud and then simply trust to luck.
