Office 365 runs on Microsoft's global cloud infrastructure. It provides key services like Exchange Online, SharePoint, and Identity Management. The logical architecture of Office 365 includes organizational productivity services, user productivity applications, and shared platform services that support streamlined management. Exchange Online in particular utilizes databases, servers, and load balancers across multiple datacenters for reliability and scalability.
