Many popular cloud applications use inter-data center paths; yet, little is known about the characteristics of these “cloud paths”. Over an eighteen month period, we measure the inter-continental cloud paths of three providers (Amazon, Google, and Microsoft) using client side (VM-to-VM) measurements. We find that cloud paths are more predictable compared to public Internet paths, with an order ...

Cloud data centers are used to maintain the shared data values for the data owners .Data owners and public verifiers are involved to efficiently audit cloud data integrity without retrieving the entire data from the cloud server. File and block signatures are used in the integrity verification process. Public data auditing schemes are tuned to verify the encrypted cloud storage environment. “On...

The most important challenge faced by a public cloud is hacking or data intrusion. If an attacker hack the cloud they can manipulate the information or disable the services. We all know that a Biometric system can ensure that rendered services can only accessed by a registered user only. It can identify an authorized user by checking the physiological features of that person. Here I wish to pro...

Enterprise networks are migrating to the public cloud to acquire computing resources for promising benefits in terms of efficiency, expense, and flexibility. Except for some public services, the enterprise network islands in cloud are expected to be absolutely isolated from each other. However, some “stealthy bridges” may be created to break such isolation due to two features of the public clou...

Using cloud computing user will be able to store and secure their data without burden of local computer. Additionally, users should be able to just use the cloud storage as if it is local, without distressing about the need to verify its integrity. By enabling and using public audit for cloud storage, it can check the integrity of the data. Finding data that are corrupted using this is difficul...

Cloud computing has the potential to significantly change the way enterprises and their IT (Information Technology) systems run, but in order to achieve this the current cloud computing model needs to be changed according to the enterprise requirements. These modifications lead to the evolution of the hybrid cloud, which is a mix of both public and private clouds. Here, we consider hybrid cloud...

The need for process improvement is an important target that does affect as well the government processes. Specifically in the public sector there are specific challenges to face .New technology approaches within government processes such as cloud services are necessary to address these challenges. Following the current discussion of „cloudification“of business processes all processes are consi...

Cloud computing has found broad acceptance in both industry and research, with public cloud offerings now often used in conjunction with privately owned infrastructure. Technical aspects such as the impact of network latency, bandwidth constraints, data confidentiality and security, as well as economic aspects such as sunk costs and price uncertainty are key drivers towards the adoption of such...

Public Clouds offer a convenient way for storing and sharing the large amounts of medical data that are generated by, for example, wearable health monitoring devices. Nevertheless, using a public infrastructure raises significant security and privacy concerns. Even if the data are stored in an encrypted form, the data owner should share some information with the Cloud provider in order to enabl...
