FusionAuth Cloud is a fully managed authentication and authorization platform offered by FusionAuth. It provides a private, dedicated instance of FusionAuth's identity management solution hosted in the cloud. FusionAuth Cloud offers features for user authentication, single sign-on, multi-factor authentication, and user management, with the infrastructure and maintenance handled by FusionAuth. The service can be deployed at multiple global locations to support high performance, high availability, and data sovereignty requirements. FusionAuth Cloud provides isolated deployments with no shared database or network paths, allowing customers to have their own server with complete access to the administrative user interface, API keys, and management via client libraries or APIs. The platform is designed to scale from a simple development server to a high availability fully replicated cluster, accommodating varying hosting needs and supporting millions of users.
