Abstract:

Technology that is fast evolving and looks promising is cloud computing. The global computing infrastructure is rapidly increasing and moving to a cloud-based design. Cloud computing enables an organization's IT infrastucture to be greater flexible, more cost-effective, faster data transfer than with traditional IT. Thus, it is essential to determine if cloud computing can provide value for emerging small and medium enterprises (SMEs) or existing ICT business firms. Cloud computing provided such solutions that can be huge benefits for SMEs in the context of IT. This study examines the potential benefits of cloud computing and the security challenges for cloud adoption while companies are migrating to a Cloud-based systems. It also provides an overview of cloud computing as well as the security challenges for organizations that arise relating to cloud computing and cloud infrastructure. The thesis was discussed both theoretical and practical aspects of Cloud computing. The theoretical part includes the theoretical background of cloud computing, its features, cloud models, services, advantages, and disadvantages of Cloud with relevant works of literature as well as the current research concerns and implications. The practical part focuses on research of using cloud computing in business organization specially for SMEs. This part discusses how cloud security risks and threats are affecting the current and protential cloud users’ decisions for adopting to their buisness. The possibilities of cloud computing are explored along with the challenges and threats in order to implement for small and medium enterprises. This study will highlight various aspects of cloud computing in order to draw a meaningful conclusion and to make recommendations on the potential usage of cloud computing in ICT-intensive business. Furthermore, we will explore existing security threats and point out the limitations of current solutions, as well as provide insights on future security possibilities.
