  ### <a id='single-node'></a>Single-node processes ###
  
  You can think of components that do not support multiple instances as single-node processes.
  Since you cannot increase the number of instances of these components, you should choose a different strategy for dealing with events that degrade availability.

  ### <a id='processes'></a>Scalable Processes ###
  
  You can think of components that support multiple instances as scalable processes.
  If you are already scaling the number of instances of such components to increase platform capacity, you need to scale further to achieve the redundancy required for high availability.
