Distribution and Deployment Scenarios
The SDX software comprises a set of interacting software modules that you can install on different hosts and connect to other internetworking devices and applications through a range of standard interfaces. This distributed architecture offers high scalability and extensive flexibility as you customize the SDX software for specific services or create your own applications based on the underlying SDX capabilities. SDX releases 3.1.1 and lower, in which the SDX software was an integrated application rather than a set of interacting modules, are fully compatible with this distributed architecture.
This chapter describes various distribution scenarios for SDX components. It also covers the architecture, component interactions, and deployment for key Enterprise Access Service Portal (EASP) cases. Finally, it includes deployment strategies for the SDX Workflow application according to the expected load of the system, integration with external OSSs, and distribution requirements.

NOTE: This chapter describes some typical scenarios, but they are by no means the only ones; many other variations are possible. |
