  +An RDBMS is used to persist Data Flow state, such as stream definitions and deployment ids.
  +It can also be used for tasks to persist execution history.

positive.code: # Whether to allow self-signed certificates during SSL validation
  # (for setting env var use SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_SKIP_SSL_VALIDATION)
  spring.cloud.deployer.cloudfoundry.skipSslValidation=false
  ```
  
  Note that you can set the following properties `spring.cloud.deployer.cloudfoundry.services`,
  `spring.cloud.deployer.cloudfoundry.memory`, and `spring.cloud.deployer.cloudfoundry.disk` as part of an individual deployment request prefixed by the `app.<name of application>`.  For example
  
  ```
  >stream create --name ticktock --definition "time | log"
  
negative.code: NOTE: Only set 'Skip SSL Validation' to true if you're running on a Cloud Foundry instance using self-signed
  certs (e.g. in development). Do not use for production.
  
  NOTE: If you are deploying in an environment that requires you to sign on using the Pivotal Single Sign-On Service,
  refer to the section <<getting-started-security-cloud-foundry>> for information on how to configure the server.
