According to the WebSphere Application Server Glossary, an application server is "a server program in a distributed network that provides the execution environment for an application program. All WebSphere Application Server configurations can have one or more application servers. With Network Deployment, you can build a distributed server environment consisting of multiple application servers maintained from a central administration point.

In a distributed server environment, you can cluster application servers for workload distribution. In a Network Deployment environment, a cell can consist of multiple nodes and node groups , which are all administered from a single point, the deployment manager. If your cell configuration contains nodes running on the same platform, it is called a homogeneous cell.

It is also possible to have a cell made up of nodes on mixed platforms. This is referred to as a heterogeneous cell. Cluster A cluster is defined as "a group of application servers that collaborate for the purposes of workload balancing and failover" in the WebSphere Application Server Glossary. In other words A cluster is a logical collection of application server processes that provides workload balancing and high availability. Application servers that belong to a cluster are members of that cluster and must all have identical application components deployed on them. Other than the applications configured to run on them, cluster members do not have to share any other configuration data.

For example, one cluster member might be running on a large multi-processor server while another member of that same cluster might be running on a small mobile computer. The server configuration settings for each of these two cluster members is very different, except in the area of the application components that are assigned to them. In that area of configuration, they are identical. The members of a cluster can be located on a single node vertical cluster , across multiple nodes horizontal cluster , or on a combination of the two.

When you install, update, or delete an application, the updates are automatically distributed to all members in the cluster. A more detailed explanation is that the deployment manager is The deployment manager uses the node agent to manage the application servers within one node. A node can only be managed by a single deployment manager and must be federated to the cell of that deployment manager. The configuration and application files for all nodes in the cell are centralized into a master configuration repository.

This centralized repository is managed by the deployment manager and synchronized with local copies that are held on each of the nodes. It is possible to create multiple nodes inside one operating system instance, but a node cannot leave the operating system boundaries. In a stand-alone application server configuration, there is only one node. With Network Deployment, you can configure a distributed server environment consisting of multiple nodes, which are managed from one central administration server.

Source: WebSphere Application Server V7: Concepts, Planning, and design Node Agent A Node Agent is "an administrative agent that manages all application servers on a node and represents the node in the management cell" according to the WebSphere Application Server Glossary In addition: In distributed server configurations, each node has a node agent that works with the deployment manager to manage administration processes A node agent is created automatically when you add federate a stand-alone node to a cell.

It is not included in the Base and Express configurations. Source: WebSphere Application Server V7: Concepts, Planning, and design In simpler terms, the node agent's purpose is to pass information between the deployment manager and the application server. They share core product files.

WebSphere Application Server is the base for the infrastructure; everything else runs on top of it. Oct 13 TPG Confidential 7. Collectively, they support the use of business rules to drive applications that support business processes. High performance environments also use WebSphere Extended Deployment as part of their base infrastructure.

Other WebSphere products provide a wide variety of additional services, as described below. Oct 13 TPG Confidential 8. You can use WebSphere to build and monitor an infrastructure to support your on demand business, and to build and extend applications that run on that infrastructure.

IBM provides extensive tools and facilities, based on industry open standards such J2EE and Eclipse, to help you build, run, manage, and optimize your WebSphere applications. Oct 13 TPG Confidential A node is an administrative grouping of application servers for configuration and operational management within one operating system instance. Each node has a node agent that works with the deployment manager to manage administration processes. A node group is a grouping of nodes within a cell that have similar capabilities.

A cell is a grouping of nodes into a single administrative domain. In the Base and Express configurations, a cell contains one node and that node contains one server. The following are the some design consideration for WebSphere deployment:. Single cell configurations Multiple cell configuration Mixed node versions in a cell Flexible management.

Clusters A cluster is a collection of servers managed together. Clusters behave as a single application server entity to accomplish a job by parallel processing.

Typically in production environment Allows the user to use the server even when a new version of the application is being rolled out. Application need to be scaled Can distribute an application across geographies to reduce the risk. User load and High availability requirements can be handled through Vertical Scaling Horizontal Scaling Vertical scaling Adding more hardware to the same machine for efficient usage of system resources Increasing number of server instances to handle user requests Represents a single point of failure Oct 13 TPG Confidential Refers to addition of more systems To distribute load Ensuring high availability Reduce single point of failure Network deployment architecture is beneficial in server administration and monitoring of horizontally scaled application Oct 13 TPG Confidential In a Horizontal clustered environment Websphere deploys application to one node at a time in the cell before moving to next node During such roll out, use of ripple start is advised, this ensures server in a cell is restarted automatically one after another thus ensuring high availability.

Care must be taken when ripple start is used in a 2 server environment and the retry interval set.

Configuration files Configuration is stored in XML files, these files can be modified for server administration Scripting client A command line interface for administration. Admin Console: Console Deployment Admin console is an inbuilt web application In Network deployment Admin console is hosted on deployment manager.

Admin console deployment involves uploading an ear to the server using web based console, hence ear should be picked from the local folder path Virtual host configuration enables a system to resemble multiple hosts Virtual host are created through different DNS name alias Different applications can be hosted on different virtual hosts to make use of available resources.
