As
expected, this system has many single-points-of-failure (SPOF) where
a single fault can cause a partial or complete Sterling Selling and
Fulfillment Foundation system or application outage. For example,
- failure of the node (node-a) will cause a complete
system outage.
- failure of the Sterling Selling and
Fulfillment Foundation agent server will affect all services provided
by the application server. In addition, it would halt all services
running the integration and application servers that depend on the
message queues.
- failure of the database instance due to software
errors or disk errors will cause a complete system outage since the
application is strongly reliant on the data in the database.
