Scalability and performance management of internet applications in the cloud
… acting as the scalability components of Amazon EC2. The current scalability implementation in Amazon EC2 is used as a reference point for evaluating the improvement in the scalable application performance. ScaleSim is fed with realistic models of the RUBiS benchmark extracted from the …

Strategy-proof resource pricing in federated systems
… type. In a federated cloud composed of four Amazon EC2 regions, we show using traces that rational users with dynamic pricing increased welfare over EC2 spot pricing. As an application, we have prototyped SkyBoxz, a federated cloud platform for managing virtual machines across multiple public …

A virtual enterprise model for enabling cloud computing for SMMEs
… architecture for SMMEs is evaluated against the Amazon EC2 pricing model to prove that our pricing model is more suitable for SMMEs. This model is based on the realisation that it is not economically viable for SMMEs to acquire their own private cloud infrastructure or even subscribe to public …

Modeling price and demand in cloud computing systems
… in an environment similar to that of the Amazon EC2 spot instance market. It is shown that the optimal strategy of a user with a deadline and sequential load can be derived from a set of dynamic programming equations, the results of which can be implemented without knowledge of the current …

Efficient and Verifiable Timing Channel Protection for Multi-Core Processors
… the keystrokes of a user in the commercial Amazon EC2 cloud. In this thesis, we explored new timing channel attacks and developed timing channel protection schemes for some of the hardware resources in a multi-core processor. Specifically, we discovered new timing channel attacks in the …

A study of gossip algorithms for internet-scale cardinality estimation of distributed XML data
… evaluation of both gossip algorithms on Amazon Elastic Compute Cloud (Amazon EC2) web service using a heterogeneous collection of XML documents. The goal of the performance evaluation is to nd if the results we obtain are consistent with the theoretical analysis of VanillaXGossip and …

On Improving Distributed Transactional Memory through Nesting, Partitioning and Ordering
… language. We conducted our evaluation study on Amazon EC2 infrastructure and compared against Paxos- and EPaxos- based state machine replication protocols. Our results reveal that Alvin provides significant speed-up for read-dominated TPC-C workloads: as much as 4.8x when compared to EPaxos on 7 …
