Today’s cloud networks are shared among many tenants. Bandwidth guarantees and work conservation are two key properties to ensure predictable performance for tenant applications and high network utilization for providers. Despite significant efforts, very little prior work can really achieve both properties simultaneously even some of them claimed so. In this paper, we present QShare, an in-net...

Existing cloud provisioning schemes allocate resources to batch processing systems at deployment time and only change this allocation at run-time due to unexpected events such as server failures. We observe that MapReduce-like jobs are timemalleable, i.e., at runtime it is possible to dynamically vary the number of resources allocated to a job and, hence, its completion time. In this paper, we ...

The present investigation is part of a more comprehensive study of old people living in Dorset (Simonds, 1954). The main survey, which was sponsored by the Health and Social Services Committee of the Dorset County Council, had as its immediate objectives: (1) to discover the extent and nature of latent welfare needs among old persons living in the county; (2) to decide which of the permissive c...

Although cloud computing service providers offer opportunities for improving the administration, reliability, and maintenance of hosted services, they also concentrate network resources and data in a small number of cloud service providers. The concentration of data and resources also entails various associated risks, including sharing the underlying infrastructure with unknown (and untrusted) ...

Most of current Software-as-a-Service (SaaS) applications are developed as customizable serviceoriented applications that serve a large number of tenants (users) by one application instance. The current rapid evolution of SaaS applications increases the demand to study the commonality and variability in software product lines that produce customizable SaaS applications. During runtime, Customiz...

Application-level multi-tenancy is an architectural design principle for Software-as-a-Service applications to enable the hosting of multiple customers (or tenants) by a single application instance. Despite the operational cost and maintenance benefits of application-level multitenancy, the current middleware component models for multi-tenant application design are inflexible with respect to pr...

Accurately predicting response times of service queries is necessary for deployments optimisation in the multi-tenant applications system. This task is particularly challenging owing to the fact that the mixes of tenants with different business scale and operating characteristics and the interaction among the concurrently running queries have a great impact on the response time of queries in th...

Key-Value SSDs (KVSSDs) introduced so far are limited in their use as an alternative to the key-value store running on host due following technical limitations. First, they were designed only for single tenant, limiting of multiple tenants. Second, mainly focused designing indexes primary key-based searches, without supporting various queries using a combination key and non-primary attributes-b...
