An Elastic Scaling Method for Cloud Security

Scaling the Performance and Cost for Elastic Cloud Web Services

Cloud computing is the latest evolution of computing where the IT resources are offered as services following the “pay-per-usage” pricing model. Cloud’s scalability feature causes variable price for resources governed by the cloud service providers. Therefore, the cloud customers’ main interest is whether the performance scales to the price for the leased resources in the cloud. In this paper w...

Auto-scaling Techniques for Elastic Applications in Cloud Environments

Data Security Algorithms for Cloud Storage System using Cryptographic Method

Cloud computing paradigm enables the users to access the outsourced data from the cloud server without the hardware and software management. For the effective utilization of sensitive data from CSP, the data owner encrypts before outsourcing to the cloud server. To protect data in cloud, data privacy is the challenging task. In order to address this problem, we proposed an efficient data securi...

An Optimization Method for Elastic Shape Matching

This note addresses the following shape matching problem: given a ‘template’ shape, numerically described by means of a computational mesh, and a ‘target’ shape, known only via a signed distance function to its boundary, we aim at deforming iteratively the mesh of the template shape into a computational mesh of the target shape. To achieve this goal, we rely on techniques from shape optimizatio...

SHEFT: An Elastic Workflow Scheduling Algorithm for Cloud Computing

Due to the complexity of scientific processes, compute and data intensive scientific workflows are often required to be executed in a distributed high-end computing environment, such as the Cloud. Most existing workflow scheduling algorithms only consider a computing environment in which the number of compute resources is bounded. Resources assigned to a workflow cannot be automatically determi...
