Therefore, edge computing can be viewed as having the same centralized This has led to a need for developing evaluation techniques that can provide quantitative measures of reliability of a cloud computing system (CCS) for efficient planning and expansion. To overcome this challenge, we intend to propose a set of models to evaluate the availability and security of MTD in cloud computing … CLOUD TECHNOLOGY . Firstly, importance of cloud computing and the significance of the quality of service (QoS) selection problem is introduced. This paper addresses an important issue in evaluating performance of cloud services for the prevalence of cloud computing nowadays. This paper consists of four major sections. This problem is overcome by cloud hosting. justification of the economic capacity evaluation and management of cloud computing as a capacity evalu-ation and investment decision. IT industry is expanding day by day and so are the businesses using the cloud services. •NIST Definition of Cloud Computing "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." Cloud computing is an advanced technology that has the potential to transform the way organizations view and deal with IT operations. Cloud computing has made a huge positive impact on the way a business runs. 4 iBm Center for the Business of Government movinG to tHE CLoUD: An introDUCtion to CLoUD ComPUtinG in GovErnmEnt ForEWorD Jonathan D.
