Unprotected application reference architecture
The unprotected application architecture is a baseline or starting point after an application is integrated with Access Gateway. It's the state before any configuration to deny direct access to the back-end protected web resource has been made.
In this architecture, a single application, referred to as a protected web resource, is served to requesting clients using Access Gateway. All URLs (Access Gateway and the back-end protected web resource) are typically resolvable using a single DNS server and are accessible to all.
This architecture meets the following requirements:
- No specialized configuration is required.
- URLs (Access Gateway and application) are entered into DNS but no further action is taken.
- It can be used as a baseline for testing and development.

Architecture
In this architecture, external clients can access the application directly if they know the internal URL/IP. Likewise internal network clients can also access the application directly. Represented by neither dotted access path being blocked.

DNS server providing DNS resolution for both the external URL and the internal (protected web resource |
|
| DMZ | Access Gateway | The Access Gateway cluster provides access to applications used by external internet clients. It's housed in the DMZ. It's typically hosted in a virtual environment such as Amazon Web Services, Microsoft Azure, Oracle OCI, or similar. See Manage Access Gateway deployment. |
| Internal network |
Internal URL |
The Internal URL, represented by the protected web resource in Access Gateway. |
| Application | The protected web resource, also referred to as the application. | |
