What is Azure Lighthouse, and how does it provide cross-tenant management for service providers? Azure Lighthouse: Azure Lighthouse is a Microsoft Azure service that enables service providers to manage resources across multiple customer tenants securely. It streamlines the management process, offering a centralized view and tools while maintaining the security and isolation of each tenant. Cross-Tenant Management: Azure Lighthouse allows service providers to gain authorized access to customers' Azure resources without needing to switch contexts or credentials. This is achieved through Azure delegated resource management, ensuring that service providers can efficiently and securely manage and monitor resources across different customer tenants from a single interface.
