A template description framework for services as a utility for cloud brokerage

Integration and mediation are two core functions that a cloud service broker needs to perform. The description of services involved plays a central role in this endeavour to enable services to be considered as commoditised utilities. We propose a conceptual framework for a cloud service broker based on two parts: a reference architecture for cloud brokers and a service description template that describes the mediated and integrated cloud services. Structural aspects of that template will be identified, formalised in an ontology and mapped onto a set of sublanguages that can be aligned to the cloud development and deployment process

Contribución a la estimulación del uso de soluciones Cloud Computing: Diseño de un intermediador de servicios Cloud para fomentar el uso de ecosistemas distribuidos digitales confiables, interoperables y de acuerdo a la legalidad. Aplicación en entornos multi-cloud.

184 p.El objetivo del trabajo de investigación presentado en esta tesis es facilitar a los desarrolladores y operadores de aplicaciones desplegadas en múltiples Nubes el descubrimiento y la gestión de los diferentes servicios de Computación, soportando su reutilización y combinación, para generar una red de servicios interoperables, que cumplen con las leyes y cuyos acuerdos de nivel de servicio pueden ser evaluados de manera continua. Una de las contribuciones de esta tesis es el diseño y desarrollo de un bróker de servicios de Computación llamado ACSmI (Advanced Cloud Services meta-Intermediator). ACSmI permite evaluar el cumplimiento de los acuerdos de nivel de servicio incluyendo la legislación. ACSmI también proporciona una capa de abstracción intermedia para los servicios de Computación donde los desarrolladores pueden acceder fácilmente a un catálogo de servicios acreditados y compatibles con los requisitos no funcionales establecidos.Además, este trabajo de investigación propone la caracterización de las aplicaciones nativas multiNube y el concepto de "DevOps extendido" especialmente pensado para este tipo de aplicaciones. El concepto "DevOps extendido" pretende resolver algunos de los problemas actuales del diseño, desarrollo, implementación y adaptación de aplicaciones multiNube, proporcionando un enfoque DevOps novedoso y extendido para la adaptación de las prácticas actuales de DevOps al paradigma multiNube

A comparison framework and review of service brokerage solutions for cloud architectures

Cloud service brokerage has been identified as a key concern for future cloud technology development and research. We compare service brokerage solutions. A range of specific concerns like architecture, programming and quality will be looked at. We apply a 2-pronged classification and comparison framework.We will identify challenges and wider research objectives based on an identification of cloud broker architecture concerns and technical requirements for service brokerage solutions. We will discuss complex cloud architecture concerns such as commoditisation and federation of integrated, vertical cloud stacks

Cloud service brokerage: a conceptual ontology-based service description framework

Cloud service brokerage has been identified as a key concern for future Cloud technology research and development. Integration, customization and aggregation are core functions of a Cloud service broker. The need to cater to horizontal and vertical integration in service description languages, horizontally between different providers and vertically across the different Cloud layers, has been well recognized. In this chapter, we propose a conceptual framework for a Cloud service broker in two parts: first, a reference architecture for Cloud service brokers; and second, a rich ontology-based template manipulation framework and operator calculus that describes the mediated and integrated Cloud services, facilitates manipulating their descriptions, and allows both horizontal and vertical dimensions to be covered. Structural aspects of that template will be identified, formalized in an ontology and aligned with the Cloud development and deployment process

Internet of Things Software Modules Marketplace

The project developed is a centralised repository of software packages to be used in cyber-physical systems. It is composed by a central database, an http api, an ftp client to serve files and a web application to manage the repository. The system also communicates via OPCUA protocol with the embed-system for real time monitoring.The advent of the Cyber-Physical Systems (CPS), a physical system representation through a vir-tual model, usually used to control a system or a process comes from the growing democratizationof the computational power. Nowadays, virtually anything can be equipped with some kind ofembedded processor to automate tasks, generate or consume some kind of data. In addition, thecontinuous development and improvement of the communication networks has helped leveragethe concept of the Internet of Things (IoT) in which things are now, themselves, connected to theInternet, exchanging data with each other and with people.In the industrial sector, CPS, also called Cyber-Physical Production Systems (CPPS) and theIoT are the main technological advances that lead to the industry fourth revolution, common des-ignated as Industry 4.0 in which the factory floor is no longer a centralized model where all thecomputation is done centrally but is now a decentralized model where industrial equipment haveembedded devices to control, automate tasks and react in a dynamic and intelligent manner to thesensed physical environment.Thereby, one of the keywords around the CPPSs is software. Software is no longer centralizedand is now distributed through several devices that comprises the system. This new approachcomes with significant changes and one of them is the reuse and distribution of the software. Itis not viable to manual deploy and install software in hundreds or thousands of devices and nothaving a way of reusing the existing software. If, on the one hand, the desire is to develop a moreintelligent process control system, on the other, flexibility, adaptability and simplicity are alsoconvenient capabilities or else intelligent manufacturing process control systems are built upon alot of resources debt. Hence, the solution is to build standards, tools and frameworks that allowthe reuse of software and its rapid deployment in the distributed devices.One option, in the Industry 4.0 field, to cope with the software reuse issue in this kind of sys-tems is the encapsulation of software in functional blocks, the Function Blocks (FBs) and their usein the function block programming paradigm, described in IEC 61499 standard. The functionalityis abstracted away in the FBs and can be reused by just deploying the them to the devices. Thisway, it is easier to manage a network by dragging and dropping these blocks, building complexapplications centrally and deploy everything to the distributed embedded devices. However, theimplementation of this standard to address the aforementioned problem brings, itself, other neces-sities such as managing the FBs, monitoring them and their previous download by the embeddeddevices.This dissertation main goal is the development of a marketplace to manage and monitor of FBs in a IEC 61499 network envisioning the filling of the previous mentioned gaps in this kindof networks. The marketplace, integrated in a IEC 61499 global solution will not only enable thedistribution of FBs among the embedded devices in a IEC 61499 compliant CPPS but also manageFBs versions, functioning as a central repository of software components, having also monitoringand statistical features, allowing the detection of flaws or malfunctions and collect statistical datai iiabout FBs usage

New Mexico: Round 1 - State-Level Field Network Study of the Implementation of the Affordable Care Act

This report is part of a series of 21 state and regional studies examining the rollout of the ACA. The national network -- with 36 states and 61 researchers -- is led by the Rockefeller Institute of Government, the public policy research arm of the State University of New York, the Brookings Institution, and the Fels Institute of Government at the University of Pennsylvania.New Mexico is no longer one of the key battleground states as it has moved more Democratic in recent presidential races, a trend driven by Latino population growth and a shift to the Democratic Party among that population. During the 2013 legislative session, Senate Bill 221 passed and authorized the establishment of a state-run New Mexico Health Insurance Exchange (NMHIX). On March 28, 2013, the governor signed Senate Bill 221 into law. Another major ACA-related decision involved Medicaid. Given the aggressive opposition from other Republican governors to the ACA, Martínez surprised some observers when she announced in early 2013 that New Mexico would expand Medicaid as long as the federal government provided the funding for the initial expansion
