A cloud that mixes use of a Public Cloud with local IT resources.
(From www.infoworld.com/d/cloud-computing/why-the-hybrid-cloud-model-the-best- approach-477, by David Linthicum, January 27, 2011)
The hybrid approach offers:
- A clear use case for Public Cloud Computing. Some aspects of IT infrastructure (e.g., storage and compute) are handled in the Cloud, and the remainder of the IT infrastructure stays on premise.
Example: Hybrid approach to operational data – keep data local, and perform analytical processing in the Cloud.
- The ability to mix and match resources between local infrastructure (typically a sunk cost but difficult to scale) with Public Cloud infrastructure (scalable and provisioned on demand). Place applications and data on the best platforms, then span the processing between them.
- An option in the discussion about whether all IT resources should exist in Public Clouds, and whether some should exist there at all. Considering compliance issues, performance requirements, and security restrictions, which local and remote platforms are best suited for which tasks?
