Alta disponibilidade na web: web clustering

Abstract

In the modern web-based systems paradigm, there is an increasing need for continuous online services availability to the users. Delays or interruption s in client-server interactions may be costly equally to the service providers and the customers. High availability solutions are used to withstand the service availability due to infrastructure critical failures. In high availability environments a failure is automatically detected and then the critical load generated is diluted into the structure. This paper presents a high availability model for web systems.
