SowjanyaAbstract - Cloud computing is not just a buzz-word, it represents a strong direction of IT industry development. Speaking of cloud computing weshould distinguish three different service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service(SaaS). The scope of this work is a model of Software as a Service. This represents the lease of computing resources on a network of remoteservers where applications are executed and data is stored. The application of cloud computing is very broad and growing daily because of manyadvantages to the users, and is driven by the increasing use of various mobile devices (laptops, tablets and Smartphone) and mobile Internetaccess being more available. Cloud computing is applicable in education, but it implies the acceptance of these services by all involved in theeducational process. Therefore, the aim of this paper is to investigate whether there is a need between our students for applications and services inthe "cloud" (SaaS), the extent to which they use them and what types of applications and services are leading. The paper analyzes and interpretsthe results of this study which provides indications of students’ willingness to "move to the cloud".Keywords: cloud computing, SaaS,PaaS,IaaS, education, studentslegacy systems and expand services.

Those educators who can deliverthese sophisticated communications environments,including the desktop applications that employersuse today, will be helping their students find betterjobs and greater opportunities in the future.According to [5], „the potential of cloud computingfor improving efficiency, cost and convenience forthe educational sector is being recognized by anumber of US educational establishments.
