# Platform Resources

> Use Altostrat SDX platform references for endpoint planning, troubleshooting, glossary terms, and operational best practices.

Platform resources are the reference pages you use when you are not configuring one feature, but making the operating environment safer and easier to run.

Use this section for endpoint planning, management tunnel behavior, troubleshooting paths, terminology, and repeatable operating practices.

## Operating Principle

SDX is designed around outbound connectivity from managed sites. Routers check in, fetch jobs, report status, and maintain a management tunnel without requiring you to expose inbound management ports to the public internet.

That means most platform preparation comes down to:

* Allowing required outbound traffic.
* Keeping control-plane policies accurate.
* Tagging and naming resources clearly.
* Watching faults, workflows, and job outcomes after changes.
* Using transient access instead of permanent broad management exposure.
