Overview
This section explains how Business Central online is structured and operated. The infrastructure page describes the model: a Microsoft Entra tenant holds environments organized by country/localization, and each environment holds companies as separate legal entities. The Environment types subtopic covers production, sandbox, preview, test and demo environments, including trials, partner sandboxes and quotas.
Operational reference pages cover update cycles (major updates in April and October, monthly minor updates, preview, grace and enforced update periods), version numbering mapped to release waves, operation limits, and country/region availability with supported languages.
Partner-facing pages cover reselling, delegated admin access through GDAP, and technical support. Trials and subscriptions covers the customer-side lifecycle. Start with the infrastructure page, then Environment types, then the page that matches your task.
