# Apps

Apps allow instances having general relationships to be grouped in a clean and organized manner. App functionality enables full control of which instances belong in an app as well setting Firewall and Access Control List (ACL) rules. Use Apps to structure all necessary components into a single place. Add checks and groups for web servers, database nodes, etc.

Apps can be created from Blueprints, which are made in Library > Blueprints > App Blueprints or from Existing Apps.
