A hybrid approach to automation that uses configuration management (CM) to build transparent and portable images can speed up deployment time while providing the benefits of both techniques. Images alone have limitations for complex applications. While CM provides transparency and control, it can significantly slow down provisioning. A process of developing CM manifests to build images, validating images, and deploying with final CM configuration exploits the strengths of each approach.
7. The promise of Cloud computing
is to commoditize the availability
of dynamic/scalable/fault tolerant
compute resources and to rapidly
construct them to meet
organizational needs.
26. CM should provide the ability to:
specify node con鍖guration as a set of components
27. CM should provide the ability to:
specify node con鍖guration as a set of components
specify the relationships between components
28. CM should provide the ability to:
specify node con鍖guration as a set of components
specify the relationships between components
inspect the state of a node or component
29. CM should provide the ability to:
specify node con鍖guration as a set of components
specify the relationships between components
inspect the state of a node or component
simulate synchronization to the spec
30. CM should provide the ability to:
specify node con鍖guration as a set of components
specify the relationships between components
inspect the state of a node or component
simulate synchronization to the spec
build a query-able inventory
47. Process:
Develop con鍖guration manifests.
Build images using con鍖gurations manifests.
Validate that the image is built correctly.
Deploy images and complete any 鍖nal con鍖guration
using con鍖guration management.
60. Summary:
Images have limitations and are not generally suf鍖cient
to manage complex applications.
Con鍖guration Management can signi鍖cantly slow
down provisioning time while providing transparency and
control.

A Hybrid approach can speed up deployment time while
providing composable infrastructure component and a
transparent image building process that better delivers the
promise of Cloud computing.
