If you've never heard of Acquia Lightning, it is an all-purpose Drupal 8 distribution with around 75 modules and extra capabilities built in. Today thousands of sites worldwide are built on Lightning. It exists in an ecosystem with vertical-specific distributions like Gov CMS (government), Open EDU (education) and Thunder (publishing). Lightning provides a clearly defined bundle of enterprise Drupal capabilities and offers a default starting point for new builds. We like to say Lightning delivers everything in Drupal core, and more.
