With the progressive implementation of digital services over virtualized infrastructures and smart devices, the inspection of network traffic becomes more challenging than ever, because of the difficulty to run legacy cybersecurity tools in novel cloud models and computing paradigms. The main issues concern i) the portability of the service...

Modern computing paradigms (i.e., cloud, edge, Internet of Things) and ubiquitous connectivity have brought the notion of pervasive computing to an unforeseeable level, which boosts service-oriented architectures and microservices patterns to create digital services with data-centric models. However, the resulting agility in service creation...

The application of effective energy management strategies in data centers is often hindered by the substantial conict between the interests of cloud users and infrastructure owners. As a matter of fact, cloud users require that the service level they are paying for is tightly met, whereas data center owners try to cut down their operational...

In last years, the security appliance is becoming a more important and critical challenge considering the growing complexity and diversification of cyber-attacks. The current solutions are often too cumbersome to be run in virtual services and Internet of Things (IoT) devices. Therefore, it is necessary to evolve to a more cooperative models,...

The consolidation of resources is one of the most efficient strategies to reduce the power consumption in data centers. Various algorithms have been proposed in order to reduce the total number of required servers and network devices. The practice developed in response to the problem of server sprawl, a situation in which multiple,...

Efficient usage of IT equipment in Data Centers requires modulating their power-consumption according to the actual workload. The most effective strategy to this aim consists in consolidating as many applications as possible on the smallest number of servers, so that idle devices can be shut down or put in low-power states. Usually, this...

The growing interest in distributed, context-aware and data-sensitive applications is pushing the evolution of computing infrastructures from centralized to distributed models, which could effectively tackle the execution of complex software frameworks over geographical scale. The concept of cloud continuum that extends computing...
