A Low Cost Two-Tier Architecture Model For High Availability Clusters Application Load Balancing
This article proposes a design and implementation of a low cost two-tier
architecture model for high availability cluster combined with load-balancing
and shared storage technology to achieve desired scale of three-tier
architecture for application load balancing e.g. web servers. The research work
proposes a design that physically omits Network File System (NFS) server nodes
and implements NFS server functionalities within the cluster nodes, through Red
Hat Cluster Suite (RHCS) with High Availability (HA) proxy load balancing
technologies. In order to achieve a low-cost implementation in terms of
investment in hardware and computing solutions, the proposed architecture will
be beneficial. This system intends to provide steady service despite any system
components fails due to uncertainly such as network system, storage and
applications.Comment: Load balancing, high availability cluster, web server cluster
An Experimental Study of Load Balancing of OpenNebula Open-Source Cloud Computing Platform
Cloud Computing is becoming a viable computing solution for services oriented
computing. Several open-source cloud solutions are available to these supports.
Open-source software stacks offer a huge amount of customizability without huge
licensing fees. As a result, open source software are widely used for designing
cloud, and private clouds are being built increasingly in the open source way.
Numerous contributions have been made by the open-source community related to
private-IaaS-cloud. OpenNebula - a cloud platform is one of the popular private
cloud management software. However, little has been done to systematically
investigate the performance evaluation of this open-source cloud solution in
the existing literature. The performance evaluation aids new and existing
research, industry and international projects when selecting OpenNebula
software to their work. The objective of this paper is to evaluate the
load-balancing performance of the OpenNebula cloud management software. For the
performance evaluation, the OpenNebula cloud management software is installed
and configured as a prototype implementation and tested on the DIU Cloud Lab.
In this paper, two set of experiments are conducted to identify the load
balancing performance of the OpenNebula cloud management platform- (1) Delete
and Add Virtual Machine (VM) from OpenNebula cloud platform; (2) Mapping
Physical Hosts to Virtual Machines (VMs) in the OpenNebula cloud platform.Comment: 6 page
