A Hybrid solution is an option best suited for medium- to large-sized organizations. In a hybrid solution, an organization moves a portion of its infrastructure to the cloud, and retains the critical infrastructure on-premise. Organizations typically choose to deploy a hybrid solution based on the following criteria:

• Strict security requirements make it impossible/difficult to allow access to a large number of external users on the corporate network
• Customization and integration with other systems in the organization is necessary
• Have sufficient budgets and IT skills to have an on-premise installation and support a cloud-based SaaS installation
