Cloud computing (CC) is a distributed computational model over a large pool of shared-virtualized computing resources (e.g., storage, processing power, memory, applications, services, and network bandwidth), where customers are provisioned and de-provisioned recourses as they need. This computing paradigm represents a vision of providing computing services as public utilities like water and electricity. The architecture of cloud computing can be split in two: front-end and back-end. The front-end represents cloud customers, organizations, or applications (e.g., web browsers) that use the cloud services. The back-end is a huge network of data centers with many different applications, system programs, and data storage systems.
Recently, CC has received considerable attention due to a number of key advantages: cost effectiveness, low management overhead, immediate access to a wide range of applications, flexibility to scale up and down information technology (IT) capacity, and mobility where customers can access information wherever they are, rather than having to remain at their desks.
Although CC has received much attention from research communities in academia as well as industry, there are many challenges facing cloud computing to be widely deployed and used. The main challenge is security, which is related to infrastructure and data.
In this talk, we investigate major challenges that may hinder the broad use of cloud computing, namely, data confidentiality, data integrity, availability, computational integrity, authentication, and auditing. In addition, we provide some perspectives and methodologies that can be used to mitigate the risks associated with cloud services. Furthermore, we highlight some open research issues that need to be investigated and tackled to achieve the wide acceptance and usage of outsourcing data storage.
