It provides an infrastructure that is scalable, usable, virtually accessible and adjustable Information Technology resources that need not be owned by an individual but can be delivered as a service over the Internet. This paper discusses the effect of Performance Expectancy on the acceptance to use Cloud Computing within public universities in Kenya. Mixed method research was used with Purposive and Stratified sampling being used to select the sample population and the sample size was 181 respondents from four public universities which were arrived at by using proportional allocation method. Questionnaires and interviews were used to capture data. The study established factors such as Performance Expectance to be a direct predictor of acceptability of cloud computing, migration to the cloud computing should be structured and incremental and more people would use Cloud Computing if given access to reliable internet and computers. Keywords: Cloud computing, performance expectancy, virtualizing 1. Introduction 1.1 Background Information Information Technology has become one of the key areas in an organization for it to succeed. The organization can communicate faster, store huge amount of data in a more effective and reliable way. The communication within an organization has been boosted through computer network. There have been network services since the intervention of Internet in the year 1970’s Martin, (2014) [20] . This has facilitated intensive online transactions. Cloud Computing services are accessible once payment is done through subscription. As a consequence, there is no need of anymore worries for a machine running the application as the supplier of the service is now taking care of it. There is no devolution to time and resources needed to develop and maintain the application used with the concept of virtualization. Serves could be utilized more effectively. Applications and other IT infrastructure are independent thus allowing servers to be easily shared by many applications that are running virtually. Virtualization of application involves packaging the application bit with everything needed to run e.g. operating system, database etc. According to Armbrust (2010) [1] , virtualization application can run anywhere thus not needed to run in a data center or in an application provider’s center. Virtualization application can also run in the cloud. Cloud Computing is currently being seen as the newest effort in providing computing resources as a service. The National Institute of Standards and Technology (NIST) in the US published a functioning definition that summarized the generally agreed aspects of Cloud Computing. According to Mell and Grance (2009a) [21] , Cloud Computing is described as a model for enabling universal, convenient, and on-demand network access so as to share a pool of configurable computing resources such as applications, networks, storage, servers, and services that can be quickly provisioned and released with minimal service provider interaction and management effort as shown in Figure 1.
