# Reference Architecture Diagrams

Authgear Enterprise Plan offers self-managed options for customers to run the whole application on their private cloud or public cloud instances using our docker images. This is generally useful for regulated industries such as Financial, Insurance or Public Sectors which must retain the processing and storage of user data on-premises or in specific geographical area.
