Sitefinity Cloud is a Platform-as-a-Service (PaaS) that runs on enterprise-grade infrastructure from Microsoft Azure. The platform is designed to ensure redundancy, uptime and elevated security. Our Sitefinity Cloud Engineers and Platform architects continuously develop the platform to provide unmatched reliability and performance. To deliver always-on experiences to our customers, we don’t allow direct access to the underlying infrastructure.
While Sitefinity Cloud customers cannot directly add additional services, they can add those in Azure/AWS/Google Cloud subscriptions of their own. We can provide what is necessary for the integrations to those services – e.g., configure a VNet tunnel.
Sitefinity Cloud enables customers to configure the platform to match their needs by adding functional and service add-ons.
One example is the ability to use Azure Logic Apps for creating and running automated workflows that integrate your applications, services and systems
