Cloud computing (CC) is rapidly growing new information technology (IT) in private, public and especially in Government sectors internationally. CC technology facilitates rather than deploy and manage an in-house physical IT infrastructure by having local servers or personal devices to manage their softwares application. This new technology helps to transfer their traditional IT services model into remote, virtualised environments, which are often hosted and managed by the third parties. Therefore, CC environment of any organisation turn prospective opportunity for cyber attackers, which is become a primary challenges of CC in the protection of valuable data from different types of attacks. CC posed a serious risk and major challenge to digital investigators, also offers sufficient opportunities to investigators for better refining the forensic science. This study summarises the key areas of CC forensics science challenges and analyses by the researched performed by other researchers. The challenges also presented along with associated literature that particularly reference them. Finally the discussion and analysis, which is based on the study finding to consider the challenges provoke by the CC forensics science on our findings.

The adoption of cloud computing in small and medium size organisations has become a significant trend in today's information technology. Therefore, there is a requirement to identify possible security challengesand guidelines for the researchers based on the adoption. Keeping in view of these elements, a systematic literature review (SLR) of cloud computing adoption in businesses and organisations was conducted. Goal: The main purpose of this research is to identify the possible opportunities, challenges, factors and guidelines for the evaluation and adoption of cloud computing (CC) for organisations intending to adopt or already using CC.

The trend in information technology has been changed by cloud computing (CC) services to facilitate the day to day business activities. CC services benefits for business and information technology (IT) includes a secure platform, reducing cost and increasing productivity. There are some challenges for some organisations that adopting CC services without ensuring that the information in the cloud is secure. The primary objective of this research is to investigate the IT and IT professional perception regarding the adoption of CC services as a new generation trend in computing technology. However, the extent of CC adoption services, to identify some of the factors motivating and some challenges affecting the adoption of CC services in England. Still some organisations are struggling, how to create a secure and cost effective CC services environment.The expected finding from this research believe to provide the certain analysis and confirm the significant factors from which perceptions are derived through classification, that can address the business and technology related issues by CC services. Especially, in this study, the CC users analyse the secure platform technologies, compatibility, cost evaluation and some other types of control they assume are beneficial for the deployment of on-premise or in the cloud environment. The interview data are presented, where CC services users reviews are collected to rate the different types of important information's related to CC services adoption. Then results are used to determine the compatibility, security and cost effectiveness are critical parameter to make this technology as a turning point for the organisation for their day to day business activities.

Cloud computing (CC) has received significant attention from different types of businesses and Industries and emerged as a new utility for businesses activities. The philosophy behind CC shows a great potential to transform a major part of the IT industry, making computing environment and resources even more attractive as a cost-effective service and changing the way IT hardware is designed and purchased. Resulting day by day more small and medium and large enterprise are adopting different types of CC services. However, strong market competitive environment for converting existing IT services to CC environment imposed different types of challenges for the CC architect. Development of CC architect environment in any organisation is a very complex process and success depends on its proper architecture design and development according to business requirements. The aim of this paper identifies the major type of key factors from literature and provides different guidelines for organisations to support the CC architecture development process. Finally, the different types of CC services generally referred to as CC architect are explained how they all work. This paper will be helpful and provides certain guidance on situations where specific types of CC services are particularly not the best option for any organization.
