Despite this, the service model is still plagued with several adoption inhibitors, one of which is lack of interoperability between proprietary application infrastructure services of public PaaS solutions. Although there is some progress in addressing the general PaaS interoperability issue through various devised solutions focused primarily on API compatibility and platform-agnostic application design models, interoperability specific to differentiated services provided by the existing public PaaS providers and the resultant disparity owing to the offered services’ semantics has not been addressed effectively, yet. The literature indicates that this dimension of PaaS interoperability is awaiting evolution in the state-of-the-art. This paper proposes the initial system design of a PaaS interoperability (IntPaaS) framework to be developed through the integration of semantic and agent technologies to enable transparent interoperability between incompatible PaaS services. This will involve uniform description through semantic annotation of PaaS provider services utilizing the OWL-S ontology, creating a knowledgebase that enables software agents to automatically search for suitable services to support Cloud-based Greenfield application development. The rest of the paper discusses the identified research problem along with the proposed solution to address the issue.Submitted Versio

Containerisation and the PaaS Cloud

Containerisation is widely discussed as a lightweight virtualisation solution. Apart from exhibiting benefits over traditional virtual machines in the cloud, containers are especially relevant for Platform-as-a-Service (PaaS) clouds to manage and orchestrate applications through containers as an application packaging mechanism. We discuss the requirements that arise from having to facilitate applications through distributed multi-cloud platforms

Cloud Application Portability: Issues and Developments

Cloud computing is a standard that is fast gaining momentum in the IT world. The availability of storage capacity that can be accessed and increased as the need arises makes computing easier. Applications can also be deployed using services provided by a cloud service provider. Portability allows utilization of applications and services across various domains. Portability could be in the area of programming language, application programming interface, data storage or data migration. Clearly, the easier it is to move services across various providers, the more attractive cloud computing becomes. The study was executed by means of review of some literature available on cloud application portability. This chapter examines current trends in cloud application portability area and gives focus for future research. In the present work, the objective is to answer the following question: what is the current trend and development in cloud application portability? Papers published in journals, conferences, white papers, and reputable magazines were analyzed. Some core topic facets were used in this review for the identification of trends in cloud application portability. The finding is that discussions on virtualization and API-specific issues are not adequate. This will be of benefit to prospective cloud users and even cloud providers

Ontology-Based Resolution of Cloud Data Lock-in Problem

Cloud computing is nowadays becoming a popular paradigm for the provision of computing infrastructure that enables organizations to achieve financial savings. On the other hand, there are some known obstacles, among which vendor lock-in stands out. Furthermore, due to missing standards and heterogeneities of cloud storage systems, the migration of data to alternative cloud providers is expensive and time-consuming. We propose an approach based on Semantic Web services and AI planning to tackle cloud vendor data lock-in problem. To complete the mentioned task, data structures and data type mapping rules between different types of cloud storage systems are defined. The migration of data among different providers of platform as a service is presented in order to prove the practical applicability of the proposed approach. Additionally, this concept was also applied to software as a service model of cloud computing to perform one-shot data migration from Zoho CRM to Salesforce CRM

SEGURANÇA EM INFRAESTRUTURA PARA INTERNET DAS COISAS

O conceito de Internet das coisas (Internet of Things - IoT) pressupõe que objetos comuns possam estar interligados à Internet, de modo a dotá-los da inteligência necessária para interagir e, de algum modo, auxiliar a vida das pessoas por meio da coleta de dados físicos, processamento e promoção de respostas através de atuadores eletromecânicos. Além do desenvolvimento de tecnologias há de se efetuar a pesquisa e o tratamento dos aspectos de segurança aplicáveis em infraestrutura para Internet das coisas. Dessa forma, este artigo visa primeiro repassar os conceitos teóricos básicos sobre os elementos que compõe a infraestrutura para Internet das Coisas, com destaque para rede de sensores sem fio, middleware e computação em nuvem. Em seguida o trabalho faz um levantamento e discute os desafios e soluções adequadas para a segurança em infraestrutura para Internet das Coisas, em específico a necessidade de manutenção da privacidade dos usuários como também a busca pela interoperabilidade entre os diversos dispositivos inteligentes. Ao final o estudo realiza uma comparação de algumas implementações em infraestrutura para Internet das Coisas em termos de atendimento aos requisitos de segurança da informação: confidencialidade, integridade, disponibilidade, autenticação, controle de acesso e não repúdio e registra os desafios e trabalhos futuros na área

PaaS-BDP a multi-cloud architectural pattern for big data processing on a platform-as-a-service model

Copyright © 2018 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved. This paper presents a contribution to the fields of Big Data Analytics and Software Architecture, namely an emerging and unifying architectural pattern for big data processing in the cloud from a cloud consumer’s perspective. PaaS-BDP (Platform-as-a-Service for Big Data) is an architectural pattern based on resource pooling and the use of a unified programming model for building big data processing pipelines capable of processing both batch and stream data. It uses container cluster technology on a PaaS service model to overcome common shortfalls of current big data solutions offered by major cloud providers such as low portability, lack of interoperability and the risk of vendor lock-in

Clouds of Things. Data protection and consumer law at the intersection of cloud computing and the Internet of Things in the United Kingdom

The article critically analyses the Internet of Things (IoT) and its intersection with cloud computing, the so-called Clouds of Things (CoT). ‘Things’ are understood as any physical entity capable of connectivity that has a direct interface to the physical world (i.e. a sensing and/or actuating capability). From another perspective (especially product liability), Things can be seen as an inextricable mixture of hardware, software, and services. Alongside a clarification of the essentials, the six factors of the CoT complexity are described and light is shed on the regulatory options (regulation, co-regulation, self-regulation, holistic approach, fragmentation). Focussing on the British legal systems, the article reports on the state of the art of CoT deployment in the United Kingdom and deals with some of the main technical and legal issues emerging from CoT. Particularly, the core will be data protection, privacy, and consumer law. Indeed, these themes are considered the most relevant by the regulators. By mastering the relevant legal issues and following the example of the United Kingdom, the Republic of Korea will be able to unleash its extraordinary potential as to the IoT, thus retaining its position as the smartest country in the world

Application Migration Effort in the Cloud

Over the last years, the utilization of cloud resources has been steadily rising and an increasing number of enterprises are moving applications to the cloud. A leading trend is the adoption of Platform as a Service to support rapid application deployment. By providing a managed environment, cloud platforms take away a lot of complex configuration effort required to build scalable applications. However, application migrations to and between clouds cost development effort and open up new risks of vendor lock-in. This is problematic because frequent migrations may be necessary in the dynamic and fast changing cloud market. So far, the effort of application migration in PaaS environments and typical issues experienced in this task are hardly understood. To improve this situation, we present a cloud-to-cloud migration of a real-world application to seven representative cloud platforms. In this case study, we analyze the feasibility of the migrations in terms of portability and the effort of the migrations. We present a Docker-based deployment system that provides the ability of isolated and reproducible measurements of deployments to platform vendors, thus enabling the comparison of platforms for a particular application. Using this system, the study identifies key problems during migrations and quantifies these differences by distinctive metrics
