Evaluating your hardware environment

Diameter Enabler installs and runs as an application on WebSphere® Application Server. It can be deployed on various hardware configurations.

WebSphere Application Server supports numerous deployment topologies. It is beyond the scope of this documentation to provide detailed steps for each topology. Therefore deployment information has been grouped into a number of broad categories. Throughout the documentation the categories are used to provide a reference point. Each component has a unique deployment strategy. Prior to deployment, review all of the planning and installation information.

Here is a list of the most commonly used topologies in a WebSphere Application Server environment:
Note: The single server topology can be used for development or the proof of concept.
Single-server topology
The components are installed on the same server. You can use this type of installation to evaluate your system for a proof-of-concept, simple interoperability testing, or simple functionality testing of the solution.

In conjunction with the single-server topology, an IBM® WebSphere Telecom Toolkit development environment can help you rapidly develop and deploy IMS™ Application Server applications. This toolkit is available as a free download. It is designed to reduce the time to develop applications that use the Diameter Enabler and other IBM WebSphere software for Telecom. The toolkit includes sample applications that demonstrate how to invoke the Diameter Enabler Web services.

Vertical scaling topology
Members of a cluster exist on the same physical machine. Some services perform better with a small or moderate size Java heap. This may not utilize all of the resources of a powerful machine, so a vertically scaled deployment allows the processor and memory to be more fully utilized, while each instance can run more efficiently in a smaller JVM heap.

Frequently, vertical scaling is combined with horizontal scaling to allow both the efficient use of resources and the benefits of physical redundancy.

Horizontal scaling topology
Members of a cluster exist on multiple physical machines, effectively and efficiently distributing the workload of a single instance. HTTP redirector products can also be used to implement horizontal scaling. Clustering is most effective in environments that use horizontal scaling because of the ability to build in redundancy and failover, to easily add new horizontal cluster members to increase capacity, and to improve scalability by adding heterogeneous systems into the cluster.

You can combine vertical and horizontal scaling techniques to increase efficiency in the environment.

The database is shared and clustered.

Development topology
An IBM WebSphere Telecom Toolkit development environment can help you rapidly develop and deploy IMS Application Server applications. This toolkit is available as a free download. It is designed to reduce the time to develop applications that use the Diameter Enabler and other IBM WebSphere software for Telecom program products. The toolkit includes sample applications that demonstrate how to invoke the Diameter Enabler Web services.
