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...

The exponential growth of the Internet, cou led with the increasing populari of dynamically generated content on the WorlJWide Web, has created the nee2 for more and faster Web servers capable of serving the over 100 million Internet users. Server clustering has emerged as a promising technique to build scalable Web servers. In this article we examine the seminal work, early products, and a sam...

Three-dimensional protein structures provide invaluable information for understanding and regulating biological functions of proteins. The GalaxyWEB server predicts protein structure from sequence by template-based modeling and refines loop or terminus regions by ab initio modeling. This web server is based on the method tested in CASP9 (9th Critical Assessment of techniques for protein Structu...

Most Internet networking devices are now equipped with a Web server for providing Web-based element management so that an administrator may take advantage of this enhanced and powerful management interface. On the other hand, for network management, an administrator normally buys and deploys SNMP-based network management platform to be customized to his network. Each management scheme has mutua...

E-commerce server reliability is critical, as downtimes cost an average of $10,000 per minute [40]. Commercial web server development today is done with fairly generic programming languages, like Java, Perl, and C#. The generality of these languages, while permitting a wide range of target applications, makes it difficult to guarantee reliability: dynamic type errors, race conditions, and resou...

The article describes an approach to evaluating the effectiveness of modern technologies for web development. Performance of different languages (C++, C#, JavaScript, PHP) is analyzed in the context of their suitability for the web. The method for determination of technology efficiency is considered in view of its cost, performance, size of community, the learning complexity and hardware requir...

As many geo-located web services will be deployed in the future, the mobile clients will be interested in locating a specific application server based on requirements such as proximity, service cost per location area, bandwidth and server utilisation rate. This paper presents a middleware system named GLWSA (Geo-Located Web Services Architecture) that aims at satisfying these requirements as we...
