2.2.6 Distributed System Configurations
Intended Use Case
The distributed system configuration allows interconnecting several projects that run
independently, either on one or several physical machines. The interconnection of the
projects allows transparent engineering and operation through them seeing them as
one and only one system. The distributed system configurations extend even further
the support of very large systems, increase robustness eliminating single point of
failures and allow geographical or discipline segregation.
Three types of distributed deployments are supported:
● Fully meshed: Each server is logically connected to all others. Clients can see all
objects in all servers. Servers can be geographically distributed. Virtual servers
are also supported.
● Segmented: A fully meshed configuration where all systems run on the same
server. Allows building larger systems on one single server.
● Hierarchical: front servers are logically connected to one head server. Clients
connected to the head server can see all objects; clients connected to front
servers can only see local objects. For campus or inherently hierarchical
applications.
