Azure
Microsoft's public cloud platform — the infrastructure Dynamics 365 runs on.
Azure is Microsoft's public cloud platform and the underlying infrastructure that hosts every Dynamics 365 app and the Power Platform. From a customer's perspective Azure shows up in several ways: as the region where the Dynamics 365 environment is provisioned, as the identity provider (Microsoft Entra ID, formerly Azure AD) that signs users in, and as the place where companies build complementary services — APIs, integrations, data warehouses, and AI models — that talk to Dynamics 365. Azure is also where partners host Logic Apps, Service Bus queues, and Functions used to integrate Business Central or Finance with third-party systems.
