To support the NIST Enterprise Architecture Model in the 1990s, it was widely promoted within the U.S. federal government as Enterprise Architecture management tool. [2] The NIST Enterprise Architecture Model is applied as foundation in multiple Enterprise Architecture frameworks of U.S. Federal government agencies and in the overall Federal ...
As cloud computing evolves, the integration of cloud services may be too complex for cloud consumers to manage alone. Cloud broker and its interactions with other parties In such cases, a cloud consumer may request cloud services from a cloud broker, instead of contacting a cloud provider directly," according to NIST Cloud Computing Reference ...
The NIST's definition of cloud computing defines Software as a Service as: [2] The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure . The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a ...
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
Cloud computing architecture refers to the components and subcomponents required for cloud computing.These components typically consist of a front end platform (fat client, thin client, mobile), back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Intercloud).
FedRAMP is governed by different Executive Branch entities that collaborate to develop, manage, and operate the program. [8] These entities include: The Office of Management and Budget (OMB): The governing body that issued the FedRAMP policy memo, which defines the key requirements and capabilities of the program
The five levels of architecture are Business Unit, Information, Information System, Data and Delivery System. The levels are separate yet interrelated... The idea if an enterprise architecture reflects an awareness that the levels are logically connected and that a depiction at one level assumes or dictates that architectures at the higher level.
The development of the open-system environment reference model started early 1990s by the NIST as refinement of the POSIX (Portable Operating System Interface) standard. POSIX is a standard for maintaining compatibility between operating systems, and addresses interoperation for communications, computing, and entertainment infrastructure.
