Edge Computing (EC) consists in deploying computational resources, e.g., memory, CPUs, at the of network, base stations, access points, and run there a part computation currently running on Cloud. This approach promises to reduce latency, inter-domain traffic enhance user experience. Since resources are scarce, resource allocation is crucial for EC. While most studies assume users interact directly with submitting sequence tasks, we instead consider that will different Service Providers...
Grid is a manifold and highly dynamic scenario. One of the fundamental issues in this environment related to jobs scheduling; since allocation resources combinatorial optimization problem, NP-hard most cases, several heuristics have been proposed achieve near-optimal solutions . This paper proposes job scheduling policy based on Alienated Ant Algorithm (AAA), new metaheuristic strategy freely inspired by ants' self-organization ability. As it will be shown, AAA able find adapting its...
Developing distributed software systems is a complex activity that involves facing not only the problems of specific application, but also those typical distribution. Computational reflection supplies means to handle different concerns with distinct components and framework in which latter can interact smoothly. We propose reflective architecture encapsulates distribution within are separated from independent addressing functional concerns. The proposed achieves thorough management...
IaaS cloud providers, as Amazon or Rackspace, provide their users with the abilities to create an own virtual environment, populate it applications, and manage a wide range of critical issues (e.g. scale up/down, load balancing, faults) by means ad hoc services. One limits these systems is lack tools that enable user have direct knowledge physical resources supporting his application. Some providers supply set for monitoring application CloudWatch) but present several limits: time...
This paper presents some experimental results on the evaluation of a resource finding algorithm for peer-to- peer grid. The algorithm, which is based spatial computing concepts, models grid as P2P overlay network, resources are obtained by suitable navigation strategy that forwards request from node to node, until one found offering desired amount resources. experimentally evaluated means software simulator, and fully characterised assessing performances afforded different strategies...
In recent years, the widespread use of container technologies has significantly altered interactions between cloud service providers and their customers when developing offering services. The shift away from Virtual Private Server scenarios in Infrastructure-as-a-Service environments requires drastic changes to deployment strategies adopted by providers. This also opens many questions what information must be supplied how improve performance user applications, especially case...
Network segmentation, also known as the Division Problem, is one of most effective techniques for computer network performance management. It has been dealt with in recent years by several researchers who have formalised problem mathematical terms. The solutions currently available literature are based on minimisation certain functionals, called fitness functions which, however, consider a limited number parameters, thus privileging only target to detriment others. This paper introduces new...
The current implementations of File System for distributed environments are mainly storage-oriented, have rigid schemas and little configurable. These aspects make them unsuitable handling the dynamicity cloud environments. In this paper, authors introduce concept as a Services (FSaaS), providing an high configurable service that enables applications to define their own rules policies managing sets files shared among themselves. particular, FSaaS aims create logical virtual space, containing...
Pulsed plasma can be produced by direct energy transfer to a solid target in nanosecond regime. Useful sources are laser and pulsed electron beams. The wavelength must chosen limit the depth absorption into submicron surface layer, avoid any dispersion during irradiation. Combining pulse duration makes ablation mechanism possible. Typically, source conditions for beams of 100 ns; 10–25 keV beams; an fluence 10–100 J/cm2. chemical composition is transferred substrate highly energetic plasma,...
In this paper, we present an implementation of the concept Multiple Option Resource Allocation (MORA) in context Multitenant Edge Computing. We assume a Network Operator (NO) owns computational resources on edge, e.g., storage and CPU co-located with mobile base station, opens them to 3rd party Service Providers (SPs), which work are video streaming services. Each SP is fully containerized Kubernetes pods. Following MORA concept, order cope limited that each can run under different...
