Disaggregated Zoned Namespace for Multi-tenancy Scenarios
The traditional block-based interface used in flash-based Solid State Drives (SSDs) imposes limitations on performance and endurance due to write amplification and garbage collection overheads. In response to these challenges, the NVMe Zoned Namespaces (ZNS) devices introduces a novel storage …

SDN based security solutions for multi-tenancy NFV
… operator to offer network-as-a-service (NaaS) to multiple tenants in a data-centre deployment. Despite the benefits brought by these technologies, they also bring along security challenges that need to be addressed and managed to ensure successful deployment and encourage faster adoption in …

Henge: An intent-driven scheduler for multi-tenant stream processing
… Henge, a system that supports intent-based multi-tenancy in modern stream processing applications. Henge supports multi-tenancy as a first-class citizen: everyone inside an organization can now submit their stream processing jobs to a single, shared, consolidated cluster. Additionally, Henge …

Mélange: Multi-tenant scheduling with adaptive eviction for graph processing clusters
Multi-tenancy is an important approach to resource consolidation in cluster management. In this thesis we design and evaluate Mélange, an efficient multi-tenant scheduler targeted towards graph processing jobs. Mélange supports job priorities and eviction, while attempting to avoid starvation. We …

Cauldron: a framework to defend against cache-based side-channel attacks in clouds
… cloud computing platforms due to high levels of multi-tenancy. In fact, there exists recent work that demonstrates such attacks on real cloud platforms (e.g., DotCloud). In this thesis we present Cauldron, a framework to defend against such cache-based side-channel attacks. Cauldron uses a …

Next Generation Operating Systems for the Datacenter
… high resource utilization and efficient multi-tenancy. Traditional operating systems, designed for an era of slower hardware, introduce significant overheads to microsecond-scale I/O that prevent applications from exploiting the full performance of the underlying hardware. Furthermore, …

Techniques for efficient high performance computing in the cloud
… schedulers, and the inherent heterogeneity and multi-tenancy in cloud are some bottlenecks for efficient HPC in cloud. Our philosophy for bridging the divide between HPC and clouds is to a) use a complementary approach of making clouds HPC-aware and HPC cloud-aware, b) consider also the unique …

Efficient radio resource management for the fifth generation slice networks
… characteristics of network slicing support the multi-tenancy paradigm, which is predicted to drastically reduce the operational expenditure (OPEX) and capital expenditure (CAPEX) of mobile network operators. Furthermore, network slices enable mobile virtual network operators to compete with one …

A multi-tenant database framework for software and cloud computing applications
… the same software and computing environment for multiple tenants. This contemporary multi-tenant service requires a multi-tenant database design that can accommodate data for multiple tenants in one single database schema. Due to multi-tenant database resource sharing in this service, the …
