III. WEBLOGIC SERVER CLUSTER
A cluster is a logical group of managed servers within a
domain. Managed servers can reside on different machine
but a cluster cannot span across more than one domain.
WebLogic Server cluster consists of multiple WebLogic FIG .1 BASIC VIRTUALIZATION IMAGE
Server, server instances running simultaneously and
working together to provide increased scalability and
reliability. A cluster appears to clients to be a single
WebLogic Server instance. The server instances that
constitute a cluster can run on the same machine, or be
located on different machines. You can increase a cluster’s
capacity by adding additional server instances to the cluster
on an existing machine, or you can add machines to the
cluster to host the incremental server instances. Each server
instance in a cluster must run the same version of
WebLogic Server.
Web applications can consist of different types of
objects, including Enterprise Java Beans (EJBs), servlets,
and Java Server Pages (JSPs). Each object type has a

This paper introduces implementation of private cloud

environment is an expensive and complex work and only
big player can implemented it – is a myth. Implementation
of cloud computing is cost effective and better utilization of
resources. In low budget project, project must run on open

Cloud computing environment on open source technology
like Oracle, JAVA, Eclipse, etc. My implementation is not
