text: **12.3.4 Horizontal and vertical scalability summary**
  
  You can use the architectural flexibility of Content Manager OnDemand (Figure 12-7 on 
  page 295) to select the correctly sized system based on your needs. A Content Manager 
  OnDemand implementation can be scaled both vertically (by using larger and larger systems) 
  and horizontally (by increasing the number of systems that are part of the Content Manager 
  OnDemand instance).
