The document discusses hybrid cloud architectures and approaches for connecting private and public clouds. It presents several current patterns for primitive hybrid architectures including migration and interface abstraction. Emerging patterns described include static placement, assisted replication, auto migration, and dynamic migration. The document argues that cloud abstraction is needed to define common information, services, processes, map to proper architectures, and select technology solutions to fully realize the benefits of hybrid cloud environments.

Data Data
- Difficult or impossible to
dynamically port or migrate.
- Little or no use of standards.
Private Cloud - Typically older platforms
mixed with cloud platforms.
- Little use of abstraction.

9. Assisted Replication
Data Data
- Code port and/or interface
compatibility.
- Some use of standards.
Private Cloud - Typically new platforms that
are code/service compatible.
- Limited use of abstraction.

10. Auto Migration
Data Data
- Auto code/VM migration
and/or interface compatibility.
- Some use of standards.
Private Cloud - Virtualization, code, and
data levels.
- Some use of abstraction.

11. Dynamic Migration
Data Data
- Dynamic VM migration
OS within single logical OS.
- Logical and physical
abstraction.
Private Cloud
- Some use of standards.
- Hybrid cloud operating
systems.
