Cloud computing is an emerging technology which enables the cloud users to access the computing resources without having to pay huge capital expenses to scale up the IT infrastructure and reduces the management cost, in both hardware and software. A cloud introduces a resource rich computing model with features such as flexibility, pay per use, elasticity, scalability, and others. In this context,...
Elasticity mechanism is the important feature of infrastructure clouds, which can add or remove resources to adapt the workload change. The elasticity mechanism impacts the quality of service and service level agreement. However, the performance of elasticity is hard to quantity. There are no efficient benchmarks to evaluate the elasticity mechanism. Exiting methods haven't considerate the different...
Elasticity is an important feature of cloud computing, and can be understood as how a computational cloud fits to variations in their workload by provisioning and deprovisioning resources. Autonomic Computing brings many concepts quite useful in the construction of elastic cloud computing solutions, such as control loops and thresholds-based rules. This paper proposes an elastic architecture for cloud...
Stream processing platforms allow applications to analyse incoming data continuously. Several use cases exist that make use of these capabilities, ranging from monitoring of physical infrastructures to pre selecting video surveillance feeds for human inspection. It is difficult to predict how much computing resources are needed for these stream processing platforms, because the volume and velocity...
