Configurations are useful when deploying packages to many different servers, and make it easy to move packages from development to production environments.
You can use variables to update packages dynamically, which enables you to customize package functionality and adapt packages to the environments in which they run. To update package properties at run time by using variables, map variables to package object properties, create configurations for the variables, deploy the configurations with the package, and then update the variable values in the configuration file to suit the new environment. At run time, the package automatically uses the updated values. This flexibility is useful when the packages that you have deployed connect to different servers, run different SQL statements, or run different child packages.
