What is a Drupal platform?
WHAT IS A DRUPAL PLATFORM?
Platform technology is a term for technology that enables the creation of products and processes that support present or future development. It can be defined as a structural or technological form from which various products can emerge without the expense of a new process/technology introduction.

WHAT IS A DRUPAL PLATFORM?
WHAT IS A DRUPAL PLATFORM?
Benefits of starting with a platform • Removes typical overhead
• Finding/installing modules • Permissions • Roles
• Provides bundled functionality • Features! • Common Views • Default Contexts
• Common CMS workflows
WHAT IS A DRUPAL PLATFORM?
Things to keep in mind • One size doesn’t fit all • Usually have to customize some behaviors • Not all bundled features might apply • Custom UX
What is Drupal multi-site?
WHAT IS DRUPAL MULTI-SITE?
Multi-site allows you to share a single Drupal installation (including core code, contributed modules, and themes) among several sites. This is particularly useful for managing the code since each upgrade only needs to be done once. Each site will have its own database and its own configuration settings, so each site will have its own content, settings, enabled modules, and enabled theme.

WHAT IS DRUPAL MULTI-SITE?
WHAT IS DRUPAL MULTI-SITE?
Benefits of Drupal multi-site • One codebase
• Easy to update contrib and platform code • Easy to roll out security patches quickly • Common code == common behavior • “Single” cloud deployment, easier to scale
• Support • Common set of features/functionality • Consistent admin experience • Simplifies training for content managers
WHAT IS DRUPAL MULTI-SITE?
Things to keep in mind • One codebase
• More difficult to add new modules/themes per site • Greater care required in QA for new code • Dev vs production environment differences • Virtual host management
• Support • Changes affect all sites • Managing site owners’ expectations
