Abstract:
This article designs and implements a low cost two-tier architecture model for high availability cluster combined with load-balancing technology and shared storage technology to achieve full facilities of the three-tier architecture for application load balancing e.g. web servers. The paper described design 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 low-cost investment in expensive hardware and computing solutions. This system can provide continuous service though any system components fail uncertainly such as network system, storage and application.
