TOTAL INTERPRETIVE STRUCTURAL MODELLING ON ENABLERS OF CLOUD COMPUTING

Abstract

Cloud computing is the delivery of computer resources over a network through web services, while the actual physical location and organization of the equipment hosting these resources are unknown to the users. Cloud computing strategy is subjected to many enablers. Interpretive structural modeling is a well proven tool for finding the interrelationship among the enablers. Total Interpretive structural model is an essential innovative version of interpretive structural modeling technique(ISM). In Total Interpretive Structural Modeling (TISM), influence/enhancement of enablers and their interrelationship is considered. Total interpretive structural model steps are identification of elements, pair-wise comparison, level partition, interaction formation, diagraph representation and formation of total interpretive structural model. The methodology of TISM is used to delineate the hierarchical relationship of enablers of cloud computing. Cloud computing is based on the concept of virtual machines. Hardware cost can be reduced by using virtualization. Different types of virtualization are operating system –level virtualization, application virtualization, service virtualization, memory virtualization, storage virtualization, virtual file system, data virtualization etc .Lack of trust between cloud users and providers has hindered the universal acceptance of cloud as outsourced computing services. To promote Multitenency we must design the cloud ecosystem to be secure, trustworthy and dependable
