Explanation

The "why" behind DT Edge Platform. Concepts and design decisions that make the rest of the docs cohere. Read these when you want understanding, not instructions.

What you'll find here

• What is DT Edge Platform? — the 5-minute big picture
• Tenancy: single vs multi — license-driven, not env-driven
• Identity and SSO — local + OIDC SSO, group→role reconcile, require_sso, session lifetime
• License states — active / grace / missing / invalid
• Edge instances — what they are, why they're a row
• Marketplace vs direct helm — when to publish a package vs install ad-hoc
• Alarms and tenant scoping — how PromQL injection keeps orgs from seeing each other's data
• Preset system — cluster_profile flag, encrypted admin passwords, coupled secrets

When to read explanation

You'll come here mostly when something doesn't behave the way you expected and you want to know whether that's a bug, a quirk, or a design choice. Each page tries to answer "why is it like this" in addition to "what is it".
