new cloud architecture for the government marketplace

old cloud architecture

my personal views on how this framework could be modified to address Federal government community requirements.

Key modifications include:
The addition of an access management layer;
Explicit SOA related layers to address workflow orchestration, application security and service management; and
An explicit connectivity layer in order to avoid a common assumption that the public Internet is always used as the networking layer in cloud computing solutions
I also briefed some advantages to using an ontology for developing federated cloud computing solutions which included:
Providing a framework for enterprise architecture development, maintenance, and use that aligns, locates, and links disparate architectures and architecture information via information exchange standards to deliver a seamless outward appearance to users;
Recogning the uniqueness and specific purpose of disparate architectures and allows for their autonomy and local governance while enabling the enterprise to benefit from their content; and
As a way to organize an enterprise’s body of knowledge (architecture) about its activities (processes), people, and things within a defined context and current/future environment.
This approach seemed to enhance the conversation and interest so with great expectation, I'm now putting this out to the wider community for consideration. Your comments are welcomed and appreciated.
