Recently, cloud computing has drawn significant attention from both industry and academia, bringing unprecedented changes to computing and information technology. The infrastructure-as-a-Service (IaaS) model offers new abilities such as the elastic provisioning and relinquishing of computing resources in response to workload fluctuations. However, because the demand for resources dynamically ch...

Current IaaS clouds provide performance guarantee on CPU and memory but no quantitative network performance for VM instances. Our measurements from three production IaaS clouds show that for the VMs with same CPU and memory, or similar pricing, the difference in bandwidth performance can be as much as 16×, which reveals a severe price-performance anomaly due to a lack of pricing for bandwidth g...

Cloud Computing is becoming more and more popular, and various cloud services have appeared to make our lives easier. Mobile devices can also benefit from Cloud services: the huge data users produce with these devices are continuously posted to online services, which may require the modification of these data. Using cloud storage services together with computation-intensive infrastructure servi...

Résumé La sécurité des Clouds est un aspect essentiel qui n’est pas forcément abordé selon le point de vue de l’utilisateur. En particulier, sur une plate-forme de type Infrastructure-as-a-Service (IaaS), il est actuellement impossible pour un utilisateur de certifier de manière fiable et sécurisée que l’environnement qu’il a déployé (typiquement sous forme d’une machine virtuelle) est toujours...

Cloud data centers have a large number of resources. Management of such huge amount of resources for a large number of consumers requires fail-safe algorithms and leasing policies. Advance Reservation (AR) leasing policy is a rigid policy, which needs resource and consumer locking at a very early point of time, while advanced reserved lease can be rejected at actual point of time when resources...

Although, the advent of fifth Generation (5G) communication networks has introduced technology enablers and system capability to support a large number devices, highly-demanding services, as well ultra-low latency high reliability, enhancements current systems will not suffice for future generation networks. Instead, disruptive paradigm needs be that ultimately enable radical evolution new ones...
