The Fifth Generation (5G) mobile networking coupled with Internet of Things (IoT) can provide innovative solutions for a wide range uses cases. flexibility virtualized, softwarized and multi-tenant infrastructures the high performance promised by 5G technology are key to cope deployment IoT use cases demanded various vertical businesses. Such incur challenging Quality Service (QoS) requirements...

Software product line engineering (SPLE) techniques revolve around a central variability model which in many cases is a feature model that documents the logical capabilities of the system as features and the variability relationships between them. In more traditional SPLE, this feature model is a result of domain analysis and requirement elicitation, while more recently this approach has been e...

Multi-tenant applications serve different customers with one application instance. This architectural style leverages sharing and economies of scale to provide cost efficient hosting. As multi-tenancy is a new concept, a common definition of the word and related concepts is not yet established and the architectural concerns are not fully understood. This paper provides an overview of important ...

Shared storage services enjoy wide adoption in commercial clouds. But most systems today provide weak performance isolation and fairness between tenants, if at all. Misbehaving or high-demand tenants can overload the shared service and disrupt other well-behaved tenants, leading to unpredictable performance and violating SLAs. This paper presents Pisces, a system for achieving datacenter-wide p...

Network slicing to support multi-tenancy plays a key role in improving the performance of 5G networks. In this paper, we propose two time-scale framework for reservation-based network backhaul and Radio Access (RAN). proposed scheme, subset slices is activated via novel sparse optimization long with goal maximizing expected utilities tenants while short are reconfigured according time-varying u...

Outsourcing of computation and storage infrastructure into the cloud entails new challenges for the architecture and design of multi-tenant datacenters. With the evolution of virtualization techniques, tenant applications do not need to be operated on dedicated servers. Software switches hereby play an important role by mediating between physical infrastructure and virtualized applications. In ...
