title: NIST Cloud Computing Reference Architecture
abstract: This paper presents the first version of the NIST Cloud Computing Reference Architecture (RA) This is a vendor neutral conceptual model that concentrates on the role and interactions of the identified actors in the cloud computing sphere. Five primary actors were identified Cloud Service Consumer, Cloud Service Provider, Cloud Broker, Cloud Auditor and Cloud Carrier. Their roles and activities are discussed in this report. A primary goal for generating this model was to give the United States Government (USG) a method for understanding and communicating the components of a cloud computing system for Federal IT executives, Program Managers and IT procurement officials.

title: The NIST Cloud Federation Reference Architecture
abstract: This document presents the NIST Federated Cloud Reference Architecture model. This actor/role based model used the guiding principles of the NIST Cloud Computing Reference Architecture to develop an eleven component model. This document describes these components individually and how they function as an ensemble. There are many possible deployments and governance options which lend themselves to create a suite of federation options from simple to complex. The basics of cloud federation can be described through the interactions of the actors in a layered three planes representation of trust, security, and resource sharing and usage. A discussion on possible future standards and use cases are also described in great detail.

title: NIST Cloud Computing Reference Architecture: Recommendations of the National Institute of Standards and Technology (Special Publication 500 292)
abstract: The National Institute of Standards and Technology, Special Publication 500 292 discusses how the adoption of cloud computing into the Federal Government and its implementation depend upon a variety of technical and non technical factors. A fundamental reference point, based on the NIST definition of Cloud Computing, is needed to describe an overall framework that can be used government wide. This document presents the NIST Cloud Computing Reference Architecture (RA) and Taxonomy (Tax) that will accurately communicate the components and offerings of cloud computing.

title: An Overview of the NIST Cloud Computing Program and Reference Architecture
abstract: Cloud computing is the next step in the continued evolution of information systems. Cloud computing allows consumers to choose what service they want, how the services will be delivered, and provides usage based. The resource pooling and rapid provisioning of cloud services allow providers to more efficiently supply these resources. This results in the consumers' needs being better met while at the same time using fewer resources (both physical assets and energy) To achieve these goals a better understanding of the implications of cloud computing along with interoperability, portability, and security standards is needed. The National Institute of Standards and Technology (NIST) has been tasked to help drive adoption of cloud computing by federal agencies through the identification and resolution of high priority interoperability, portability and security issues.

title: Cloud Computing Reference Architecture from Different Vendor's Perspective
abstract: The provision of on demand access to Cloud computing services and infrastructure is attracting numerous consumers, as a result migrating from traditional server centric network to Cloud computing becomes inevitable to benefit from the technology through overall expense diminution. This growth of Cloud computing service consumers may influence the future data centers and operational models. The issue of inter cloud operability due to different Cloud computing vendors Reference Architecture (RA) needs to be addressed to allow consumers to use services from any vendor. In this paper we present the Cloud computing RA of major vendors available in scientific literature and the RA of National Institute of Standard Technology(NIST) by comparing the nature of their RA (role based/layer based) and mapping activities and capabilities to the layer(s) or role(s)

title: Cloud Computing Architecture And Applications Security
abstract: Cloud computing is developed to tackle storage limitations and information security. It's being considered as a new computing paradigm that offers dynamic and flexible resource allocation. Business owners have become more attracted in the possibilities of using cloud computing because it increases the reachability of their services and reduces the need for physical resources. In this paper, the cloud computing architecture is described with a brief actors' roles based reference model. This model allows the stakeholders to understand the overall view of functions, activities, and responsibilities to evaluate and assign the risk of services. At the end of this work, several open researches for security applications is concluded and discussed. Index Terms Cloud computing, Cloud architecture, NIST, Reference model, 3DES, AES, Security applications.

title: Modeling an IaaS Broker Based on Two Cloud Computing Reference Models
abstract: Due to its rapid growth, short history and lack of regulation, eliciting the requirements for an information system broker in an IaaS Cloud Computing context can be a challenging task. Reference models such as the NIST Cloud Computing Reference Architecture and The Open Group Cloud Ecosystem Reference Model stand as recognized models in this domain. Additionally, Use Case models allow representing the process view of a system and can be considered as an adequate elicitation method for the cloud. Mapping these processes on both reference models may allow for a Cloud Computing suitability check for a proposed solution. Along these lines, we present the results of our work on an industrial project for a cloud broker platform in an IaaS service model. This approach allows for a feasibility and consistency check of the elicited system, pointing some incompletions and flaws, but also important differences in the reference models.

title: Using the NIST Reference Model for Refining Logical Architectures
abstract: The emergence of the Internet as a ubiquitous means of communication fostered the growth of new business and service models based on Cloud Computing. Information and Communication Technology companies use reference models to define their Cloud Computing strategies.  This paper aims to present the use of NIST reference architecture in the design of Cloud Computing architectures by employing a method that enables the application of the reference architecture to the refinement of logical architectures.

title: Cloud service orchestration based architecture of OpenStack Nova and Swift
abstract: OpenStack Nova and Swift are responsible for provisioning and management of compute and storage resources, respectively, in a need based manner. These cloud software are widely adopted by several popular organizations for deploying their compute and storage services. To have a cloud platform that is easily upgradable, modifiable and maintainable, there is a need for a well defined detailed architecture. For this, there is a need of identifying the internal components and processes required for the functioning of the software. In this paper, we present architecture of OpenStack Nova and Swift in conformance to layered architecture defined for service orchestration component of the NIST cloud computing reference architecture. The proposed architecture identifies the components, sub components and their interaction, at the layers defined for service orchestration component and provides insight into internal working and associated processes of Nova and Swift. The proposed architecture is beneficial for cloud provider and system administrator in maintaining and improving quality of the system.
