Patterns: Implementing Self-Service in an SOA Environment

Chapter 1. Patterns for e-business 13

Figure 1-7 Directly Integrated Single Channel application pattern::Runtime pattern

These are just two examples of the possible Runtime patterns that are available.

Each Application pattern will have one or more Runtime patterns defined. You

can modify these Runtime patterns to suit the client’s needs. For example, the

client might want to add a load-balancing function and multiple application

servers.

1.2.4 Reviewing Product mappings

The last step in defining the network structure for the application is to correlate

real products with one or more runtime nodes. The Patterns Web site shows

each Runtime pattern with products that have been tested in that capacity. The

Product mappings are oriented toward a particular platform. However, it is more

likely that the client will have a variety of platforms involved in the network. In this

case, you can mix and match product mappings.
