The document discusses hybrid cloud scenarios that combine public and private clouds. It defines private and public clouds and their differences. Private clouds provide more control while public clouds provide scale. Hybrid clouds blend both models. The document outlines several hybrid cloud deployment patterns and application patterns, including using public clouds for variable capacity and private clouds for predictable workloads. It emphasizes the need for cloud-optimized application design and integration across cloud services when building hybrid applications.

5. Private CloudImplementation of cloud services on resources that are dedicated to your organization, whether they exist on-premises or off-premisesTypically, your organization owns and controls the resources/assets, definition of services, costs and risksVariations exist – such as hosted and virtual private cloudsMicrosoft solutionsWindows Server 2008 R2 Hyper-V, System Center (IaaS)Windows Azure Appliance (PaaS)

6. Public CloudImplementation of cloud services on resources that are shared between many customers, managed off-premisesTypically, cloud provider owns and controls the resources/assets, definition of services, costs and risksVariations exist – such as hosters and integrated cloud platformsMicrosoft solutionsOffice 365 (SaaS)Dynamics CRM Online (SaaS)Windows Intune (SaaS)Windows Azure platform (PaaS)
