Deployment Models

• Public cloud: This computing infrastructure is hosted at the vendor’s workplace. The end user cannot view the infrastructure. The computing infrastructure is shared between companies.
• Private cloud: The computing infrastructure is dedicated to the customer and is not shared with any other companies. They are costly and highly secure than public clouds.
• Community cloud: The cloud infrastructure is shared between the companies of the same community.

Co-Existent use case

• Cloud bursting
• Use of cognitive services from a public cloud
• Licensing restrictions
• Non availability of a service on the Public cloud

A Strategy for Hybrid Cloud Success

• Choose a single framework—a “cloud operating system”
• Modernize your on-premises environments in accordance with that framework.
• Choose only public clouds and CSPs compatible with that framework.
