Mixed Deployment
Mixed deployment is characterized by high load, external and internal OSSs, and a single site with redundancy.
Mixed deployment is similar to the high-availability scenario, but it also includes the externalized case (see Figure 37). This architecture solves the problem of using both external (Web-based, for example) and internal OSS applications.
The important detail here is the use of private workflow engines for the OSMW, because the external OSS application does not communicate with the OSMs that communicate with the internal OSS application.
The natural extension of this case is to distribute it on multiple sites. The idea is the same, but the distributed and Web-based cases are mixed.
