A cloud computing as a distributed computing emerging paradigm in which data and services are available in data centers extensible and can be accessed transparently since devices (computers, phones, clusters, ) connected via the Internet. Cloud computing solve problems of scalability and availability and insure distributed computing. This paper aims to provide an architecture for services deployed...
Nowadays, virtualization is an important technique that offers illimited resources to network users. It allows users to share switch's resources in time and space. Sharing in time is done by scheduling algorithms determining at which moment each input queue is matched with an output queue. Regarding sharing in space, it takes place in the queues which are split into multiple virtual queues. Being...
Among the many limitations that the clouds are facing today, the heterogeneity of IT resources and networks. The dynamic deployment and on-demand applications are also major challenges. To ensure this deployment, it is essential to rely on methods of managing applications and services in a cloud. This paper proposes to apply the concept of Virtual Appliance for cloud architectures to ensure the dynamic...
