   MicroBOSH does not require that you specify a database in the deployment manifest. If you do not specify a database, MicroBOSH uses an internal Postgres database. To configure MicroBOSH to use an external Postgres database, add a `postgres` sub-block to your deployment manifest and redeploy.

negative.code: title: Connecting BOSH or MicroBOSH to an External Postgres Database
  ---
  
  The BOSH Director or MicroBOSH Director stores deployed VM status information in an internal or an external database. An internal database might be sufficient for your deployment; however, a highly-available external database can improve performance and scalability and protect against data loss.
  
  This topic describes how to connect BOSH or MicroBOSH to a highly-available external Postgres database.
  
  
  ##<a id="bosh"></a>BOSH ##
  
  BOSH requires that the BOSH deployment manifest contains database configuration information. By default, the manifest includes a pre-configured `postgres` sub-block that connects BOSH to an internal Postgres database. To configure BOSH to use an external Postgres database, modify the manifest with your external database connection information and redeploy.
