In this paper, we present a software project management of agile development in cloud computing environments, called as TOAST, which is constructed based on the MOAT model. MOAT is a two-layer model of software project management using agile methodology, which is especially designed for managing software projects in cloud computing environments. In MOAT, the primary operations of agile software...

Attribute-based encryption has the potential to be deployed in a cloud computing environment to provide scalable and fine-grained data sharing. However, user revocation within ABE deployment remains a challenging issue to overcome, particularly when there is a large number of users. In this work, we introduce an extended proxy-assisted approach, which weakens the trust required of the cloud ser...

The objective of our paper is to propose a Cloud computing framework which is feasible and necessary for handling huge data. In our prototype system we considered national ID database structure of Bangladesh which is prepared by election commission of Bangladesh. Using this database we propose an interactive graphical user interface for Bangladeshi People Search (BDPS) that use a hybrid structu...

Security concerns are a substantial impediment to the wider deployment of cloud storage. There are two main concerns on the confidentiality of outsourced data: i) protecting the data, and ii) protecting the access pattern (i.e., which data is being accessed). To mitigate these concerns, schemes for Oblivious Storage (OS) have been proposed. In OS, the data owner outsources a key-value store to ...

Cloud computing is bringing a revolution in computing environment replacing traditional software installations, licensing issues into complete on-demand services through internet. Microsoft office 365 a cloud based office application is available to clients online hence no need to buy and install the software. On Facebook a social networking website, users upload videos which uses cloud provide...

In traditional Internet of Things (IoT) ecosystems, fog devices transmit data from sensors to a centralized cloud server. Issues with security and upkeep while updating firmware for millions smart devices, single points failure, as well third-party Cloud server administration, the difficulty frequently on presents maintenance issues bottleneck in information flows, all raise privacy concerns. B...

In this paper, we have considered a Markovian bulk-service queue for cloud computing architecture. The multiple class i users from the public cloud entering into the queue are naturally based on the FCFS discipline. Partial batch service mode and full batch service mode have considered for accessing cloud database. The requesting and service of the public cloud has been modelled using queueing ...

Cloud Computing plays a vital role in IT field which develop the field of computer in fast manner. Cloud Computing is nothing but sharing of resources to their clients in efficient way. It works under the concept of virtualization and by three different types of service providers such as SaaS, IaaS and PaaS. In cloud computing we come across some problems in security and data stored in the clou...

Cloud computing facilitates data protection, privacy and medical record access. Computing is the new trend to reduce the investment in business to satisfy the client needs using internet. The various cloud services provides infrastructure, software and platform. In cloud computing, data is moved to a remote location. Users store their data conscientiously in the cloud and return back when it is...
