Cloud computing provides many opportunities for enterprises by offering a range of computing services. In today´s competitive environment, the service dynamism, elasticity, and choices offered by this highly scalable technology are too attractive for enterprises to ignore. These opportunities have opened up a new dimension of challenges by introducing a different type of trust scenario. Today, the problem of trusting cloud computing is of supreme concern for most enterprises. The diversity of cloud service offerings makes it necessary for customers to evaluate the service levels of different cloud providers in an objective way such that required quality, reliability or security of an application can be ensured.
