Building a Rails applications with Scrivito completely avoids the maintenance effort usually associated with databases. No more replication, no backups. The cloud does it for you.
This analogously applies to the infrastructure usually required for making the content searchable. Through Scrivito, every website project is attached to an Elasticsearch engine. Your content is indexed automatically.
The content to be delivered by your Rails application, as well as the search functionality, can be accessed through the Scrivito SDK gem, that smoothly integrates the Scrivito CMS functionality into your Rails application. Towards your Rails application, the SDK behaves almost like a database adapter and additionally provides helper tools for rendering and manipulating content.
