Information Retrieval in Clouds
Abstract
Cloud computing nowadays is prevalent in our daily life, and it has been commonly used to provide IT [Information Technology] services over the Internet. Virtualization, as the foundation and main enabling technology of cloud computing, has played a crucial role in computing resource management inside a cloud,sharing finite hardware resources among a large number of software systems and programs. However, the security of virtualization has become a major concern for organizations and individuals who are hesitating to deploy their critical applications or data in cloud environments. This is mainly due to the fact that a hypervisor, which is a key component of virtualization and is controlled by cloud vendors, runs directly on the hardware or a host operating system [OS] to create and manage the guest OSes and have a higher privilege level than guest OSes. While significant research efforts have been paid to understand the cyber threats exposed by cloud computing, it is yet unclear how insecure/secure cloud environments are.
