Cloud computing and cloud storage are becoming an attractive option for businesses and governmental organizations in need of scalable and reliable infrastructures. Cloud providers, e.g., Amazon or Google, have substantial expertise and resources, allowing them to rent their services at very competitive prices. Cloud users are drawn by the ability to pay for only what they need, but maintain the ability to scale up if requirements change. Users can now take advantage of highly reliable storage solutions without investing large amounts of money for data centers upfront.
