Vertical and horizontal elasticity for dynamic virtual machine reconfiguration
نویسندگان
چکیده
Today, cloud computing applications are rapidly constructed by services belonging to different cloud providers and service owners. This work presents the inter-cloud elasticity framework, which focuses on cloud load balancing based on dynamic virtual machine reconfiguration when variations on load or on user requests volume are observed. We design a dynamic reconfiguration system, called inter-cloud load balancer (ICLB), that allows scaling up or down the virtual resources (thus providing automatized elasticity), by eliminating service downtimes and communication failures. It includes an inter-cloud load balancer for distributing incoming user HTTP traffic across multiple instances of inter-cloud applications and services and we perform dynamic reconfiguration of resources according to the real time requirements. The experimental analysis includes different topologies by showing how real-time traffic variation (using real world workloads) affects resource utilization and by achieving better resource usage in inter-cloud.

متن کاملElastic Virtual Machine for Fine-grained Cloud Resource Provisioning
Elasticity is one of the distinguishing characteristics associated with Cloud computing emergence. It enables cloud resources to auto-scale to cope with workload demand. Multi-instances horizontal scaling is the common scalability architecture in Cloud; however, its current implementation is coarse-grained, while it considers Virtual Machine (VM) as a scaling unit, this implies additional scali...
متن کاملElastic Memory Management of Virtualized Infrastructures for Applications with Dynamic Memory Requirements
This paper addresses the impact of vertical elasticity for applications with dynamic memory requirements when running on a virtualized environment. Vertical elasticity is the ability to scale up and scale down the capabilities of a Virtual Machine (VM). In particular, we focus on dynamic memory management to automatically fit at runtime the underlying computing infrastructure to the application...
متن کاملA hybrid cloud controller for vertical memory elasticity: A control-theoretic approach
Web-facing applications are expected to provide certain performance guarantees despite dynamic and continuous workload changes. As a result, application owners are using cloud computing as it offers the ability to dynamically provision computing resources (e.g., memory, CPU) in response to changes in workload demands to meet performance targets and eliminates upfront costs. Horizontal, vertical...
متن کاملVertical Scaling Capability of OpenStack - Survey of Guest Operating Systems, Hypervisors, and the Cloud Management Platform
With the emergence of cloud computing, resources can be dynamically scaled. A common scaling approach is the addition and removal of virtual machines, known as horizontal scaling. Horizontal scaling can take several minutes but erratic and sudden changes in demand take place within seconds. Therefore, vertical scaling has been introduced, changing the resources of an existing virtual machine du...
