What is NIST architecture?
The NIST Enterprise Architecture Model is a five-layered model for enterprise architecture , designed for organizing, planning, and building an integrated set of information and information technology architectures. Data Delivery Systems (Software, Hardware, Communications) support the data architecture .
What is cloud reference model?
The Cloud Reference Model is a framework used by customers and vendors to define best practices for cloud computing. The reference model defines five main actors: the cloud consumer, cloud provider, cloud auditor, cloud broker, and cloud carrier.
Which two of the following are among the major five actors of the NIST Cloud Computing Reference Architecture?
The NIST cloud computing reference architecture defines five major actors : cloud consumer, cloud provider, cloud auditor, cloud broker, and cloud carrier. Each actor is an entity (a person or an organization) that participates in a transaction or process and/or performs tasks in cloud computing .
What are the five essential characteristics of the cloud as defined by NIST?
The NIST definition lists five essential characteristics of cloud computing: on-demand self -service, broad network access, resource pooling, rapid elasticity or expansion, and measured service.
What is NIST in cloud?
In 2011, NIST defined cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service
What is a reference architecture document?
A reference architecture is a document or set of documents that provides recommended structures and integrations of IT products and services to form a solution. The reference architecture embodies accepted industry best practices, typically suggesting the optimal delivery method for specific technologies.
What is meant by reference model?
From Wikipedia, the free encyclopedia. A reference model —in systems, enterprise, and software engineering—is an abstract framework or domain-specific ontology consisting of an interlinked set of clearly defined concepts produced by an expert or body of experts to encourage clear communication.
What are the fundamental components introduced in cloud reference model?
As shown in Figure 1, the NIST cloud computing reference architecture defines five major actors: cloud consumer, cloud provider, cloud carrier, cloud auditor and cloud broker.
What are the different cloud technologies?
There are three main service models of cloud computing – Infrastructure as a Service (IaaS ), Platform as a Service ( PaaS ) and Software as a Service (SaaS ).
What is security reference architecture?
Security is a fundamental concern in clouds and several cloud vendors provide Security Reference Architectures (SRAs) to describe the security level of their services. A SRA is an abstract architecture without implementation details showing a conceptual model of security for a cloud system.
Which cloud delivery model could be considered an amalgamation of other types of delivery models?
hybrid delivery model
Which of the following is an essential concept related to cloud?
What does NIST stand for?
National Institute of Standards and Technology
What are the essential characteristics of cloud?
This cloud model is composed of five essential characteristics: On-demand self-service . Broad network access . Resource pooling . Rapid elasticity . Measured Service.
What are the 4 main tenets of cloud computing?
Usable, Collaborative, Reproducible, and Extensible Four Key Tenets of Cloud Computing . Making data available isn’t enough to make it usable. The best science happens in teams. Reproducibility shouldn’t be hard. The impact of TCGA is extended by new data and tools. Current status.
