This tutorial shows how to set up a two-node Apache web server cluster that provides high-availability. In front of the Apache cluster we create a load balancer that splits up incoming requests between the two Apache nodes. Because we do not want the load balancer to become another "Single Point Of Failure", we must provide high-availability for the load balancer, too. Therefore our load balancer will in fact consist out of two load balancer nodes that monitor each other using heartbeat, and if one load balancer fails, the other takes over silently

S'il est encore difficile d'installer un cluster MySQL en 15 minutes, les tutoriels pour assurer la configuration initiale sont de plus en plus nombreux. En voici pas moins de quatre, avec des versions récentes de MySQL (5.1 recommandée). Les limitations du Cluster le réservent encore pour des applications spécialisées. Toutefois, le temps de mise en place et la courbe s'apprentissage se réduisent à chaque version.

This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package that provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

Pipeline is a search engine and web portal that combines the result relevance of a PageRank style link algorithm with the navigation utility of results clustering.

In the past several years, grid computing has emerged as a way to harness and take advantage of computing resources across geographies and organizations. In this IBM Redbook, we describe a generalized view of grid computing including concepts, standards, and ways in which grid computing can provide business value to your organization. In a nutshell, grid computing is all about virtualization that enables businesses to take advantage of a variety of IT resources in order to be more responsive to demands of the business and increase availability of applications while reducing both infrastructure and management costs.

APHID is an acronym for Asycnhronous Parallel Hierarchical Iterative Deepening. The APHID game-tree search algorithm attempts to accomplish many goals: * to test out the viability of asynchronous search methods for parallel alpha-beta based search. * to develop an algorithm that works well across all hardware platforms and applications. * to implement a tool that can be easily inserted into legacy sequential search algorithms.
