点击翻译按钮获取中文摘要

Clients using cloud services are often caught unaware of some of their drawbacks.  These include: (1) the necessity to explicitly replicate services to accommodate zone failures, (2) the inability to have fine grain control over location of data, and (3) the fact that large megadata centers may reside in areas subject to vastly different privacy laws. Despite these drawbacks, clouds provide affordable, effective, dynamically scalable infrastructure vital to meet the needs of growing user populations and massive data sets. Almost every dimension of society relies on today's cloud services, including research, government, industry, healthcare, education, citizen science, and entertainment.
