Based On The JBoss AS7Study Of Enterprise Distributed Deployment Platform

With the rapid development of the Internet, the huge increase in the amount of access tothe network at the same time also led to the amount of information into a geometric growth,network access of the flask already appear, this kind of service overloading problem is alsoincreasingly becoming a severe test that the network and its Web application server must face.This paper studys how to use the latest Jboss application server Jboss AS7to design adistributed implementation architecture of server cluster to achieve load balancing, solvingthe network congestion and server overload problems. It provides the tachnical support tostudy the network server load balancing.JBoss Application Server is a Java open source, integration and development of fullservice implementation based on J2EE. This paper analysis the application server used; Theadvantage of the JBoss application server relative to other application servers; The evolutionof the JBoss application server history; the new features of the latest JBoss application serverJBoss AS7: the JBoss application server based on module classloader to realize the JBoss7modular hot deployment and hot unload and the concept of domain (domain).During uses the new JBoss AS7two operation modes: single server model(standalone model) and the domain model (domain model).Domain model: the domain modelis a main control field which is responsible for running and managing multiple jboss servertopology, in order to realize the unified management of multiple servers; Singleton pattern:single instance model therefore incredible refers only to implement a jboss application serverinstance running and management. JBoss AS7domain (domain) model make many sets ofJBoss AS the server’s configuration can converge, unified configuration, deployment, in orderto achieve the management of multiple JBoss AS server, to realize centralized management.The purpose of the domain is composed of multiple servers to a server group, and for multiplehosts within a server group:(1)A single point of centralized configuration:via a domain controller, DomainController, unified configuration of the host of the group.(2)single unified deploy, the domain controller will project a deployment to group allhosts.This article focuses on how to deploy a distributed enterprise large-scale deploymentplatform, through the use of JBoss AS7domain model of unified management and unifieddeployment of multiple server or server group method, respectively. The master node deployment, constructs the enterprise distributed deployment platform system from the node,using the JBoss mod_cluster load balancer to solve the access allocation, realization of servercluster function, solve the enterprise web application problems. Through the test on singlemode and the domain model in traffic has reached1000000per second, the maximum amountof data access domain mode is2.5times of the single mode, improve the access efficiency ofthe server. The deployment of jpetstore applications, and also to the server asynchronousrequest, to perform the update or query the database, rather than to refresh the whole page.The end user does not have to understand is to communicate with the server browser, whereassite seems like an instant response. To achieve high availability of erver.
