A new MDA-SOA based framework for intercloud interoperability

Cloud computing has been one of the most important topics in Information Technology which aims to assure scalable and reliable on-demand services over the Internet. The expansion of the application scope of cloud services would require cooperation between clouds from different providers that have heterogeneous functionalities. This collaboration between different cloud vendors can provide better Quality of Services (QoS) at the lower price. However, current cloud systems have been developed without concerns of seamless cloud interconnection, and actually they do not support intercloud interoperability to enable collaboration between cloud service providers. Hence, the PhD work is motivated to address interoperability issue between cloud providers as a challenging research objective. This thesis proposes a new framework which supports inter-cloud interoperability in a heterogeneous computing resource cloud environment with the goal of dispatching the workload to the most effective clouds available at runtime. Analysing different methodologies that have been applied to resolve various problem scenarios related to interoperability lead us to exploit Model Driven Architecture (MDA) and Service Oriented Architecture (SOA) methods as appropriate approaches for our inter-cloud framework. Moreover, since distributing the operations in a cloud-based environment is a nondeterministic polynomial time (NP-complete) problem, a Genetic Algorithm (GA) based job scheduler proposed as a part of interoperability framework, offering workload migration with the best performance at the least cost. A new Agent Based Simulation (ABS) approach is proposed to model the inter-cloud environment with three types of agents: Cloud Subscriber agent, Cloud Provider agent, and Job agent. The ABS model is proposed to evaluate the proposed framework.Fundação para a Ciência e a Tecnologia (FCT) - (Referencia da bolsa: SFRH SFRH / BD / 33965 / 2009) and EC 7th Framework Programme under grant agreement n° FITMAN 604674 (http://www.fitman-fi.eu

An introduction to Graph Data Management

A graph database is a database where the data structures for the schema and/or instances are modeled as a (labeled)(directed) graph or generalizations of it, and where querying is expressed by graph-oriented operations and type constructors. In this article we present the basic notions of graph databases, give an historical overview of its main development, and study the main current systems that implement them

ClouNS - A Cloud-native Application Reference Model for Enterprise Architects

The capability to operate cloud-native applications can generate enormous business growth and value. But enterprise architects should be aware that cloud-native applications are vulnerable to vendor lock-in. We investigated cloud-native application design principles, public cloud service providers, and industrial cloud standards. All results indicate that most cloud service categories seem to foster vendor lock-in situations which might be especially problematic for enterprise architectures. This might sound disillusioning at first. However, we present a reference model for cloud-native applications that relies only on a small subset of well standardized IaaS services. The reference model can be used for codifying cloud technologies. It can guide technology identification, classification, adoption, research and development processes for cloud-native application and for vendor lock-in aware enterprise architecture engineering methodologies

OpenIaC: open infrastructure as code - the network is my computer

Modern information systems are built fron a complex composition of networks, infrastructure, devices, services, and applications, interconnected by data flows that are often private and financially sensitive. The 5G networks, which can create hyperlocalized services, have highlighted many of the deficiencies of current practices in use today to create and operate information systems. Emerging cloud computing techniques, such as Infrastructure-as-Code (IaC) and elastic computing, offer a path for a future re-imagining of how we create, deploy, secure, operate, and retire information systems. In this paper, we articulate the position that a comprehensive new approach is needed for all OSI layers from layer 2 up to applications that are built on underlying principles that include reproducibility, continuous integration/continuous delivery, auditability, and versioning. There are obvious needs to redesign and optimize the protocols from the network layer to the application layer. Our vision seeks to augment existing Cloud Computing and Networking solutions with support for multiple cloud infrastructures and seamless integration of cloud-based microservices. To address these issues, we propose an approach named Open Infrastructure as Code (OpenIaC), which is an attempt to provide a common open forum to integrate and build on advances in cloud computing and blockchain to address the needs of modern information architectures. The main mission of our OpenIaC approach is to provide services based on the principles of Zero Trust Architecture (ZTA) among the federation of connected resources based on Decentralized Identity (DID). Our objectives include the creation of an open-source hub with fine-grained access control for an open and connected infrastructure of shared resources (sensing, storage, computing, 3D printing, etc.) managed by blockchains and federations. Our proposed approach has the potential to provide a path for developing new platforms, business models, and a modernized information ecosystem necessary for 5G networks.publishedVersio

A DEVSECOPS APPROACH FOR DEVELOPING AND DEPLOYING CONTAINERIZED CLOUD-BASED SOFTWARE ON SUBMARINES

There are unique challenges for using secure cloud services in disconnected resource-constrained environments and with controlled data. To address those challenges, this thesis introduces a tactical-edge platform-as-a-service (PaaS) solution with a declarative-delivery method for submarine Consolidated Afloat Network Enterprise Services (CANES) operating systems. The PaaS is adapted from the Department of Defense’s Big Bang core elements for submarine-focused outcomes. Using the Team Submarine Project Blue initiative as a case study, this thesis consists of a feasibility study for running containerized applications on different submarine-compatible baselines and applying a prototype declarative software-delivery method called ZARF. We demonstrated the feasibility of using ZARF for packaging and automated deployment of the Project Blue PaaS and its software to the submarine CANES infrastructure. This research culminated in successful integration tests on a current and future submarine hardware and software baseline. The thesis documents the execution of the research, lessons learned, and recommendations for the Navy’s path forward for development of secure software and declarative deployment in air-gapped environments.Outstanding ThesisLieutenant, United States NavyApproved for public release.

Доповнена реальність як інструмент відкритої наукової платформи дослідницької співпраці у віртуальних спільнотах

The provision of open science is defined as a general policy aimed at overcoming the barriers that hinder the implementation of the European Research Area (ERA). An open science foundation seeks to capture all the elements needed for the functioning of ERA: research data, scientific instruments, ICT services (connections, calculations, platforms, and specific studies such as portals). Managing shared resources for the community of scholars maximizes the benefits to society. In the field of digital infrastructure, this has already demonstrated great benefits. It is expected that applying this principle to an open science process will improve management by funding organizations in collaboration with stakeholders through mechanisms such as public consultation. This will increase the perception of joint ownership of the infrastructure. It will also create clear and non-discriminatory access rules, along with a sense of joint ownership that stimulates a higher level of participation, collaboration and social reciprocity. The article deals with the concept of open science. The concept of the European cloud of open science and its structure are presented. According to the study, it has been shown that the structure of the cloud of open science includes an augmented reality as an open-science platform. An example of the practical application of this tool is the general description of MaxWhere, developed by Hungarian scientists, and is a platform of aggregates of individual 3D spaces.Відкрита наука визначається як загальна політика, спрямована на подолання бар'єрів, що перешкоджають впровадженню Європейського дослідницького простору (ERA). Відкритий науковий фонд прагне охопити всі елементи, необхідні для функціонування ERA: дані досліджень, наукові інструменти, ІКТ-послуги (з'єднання, розрахунки, платформи та конкретні дослідження, такі як портали). Управління спільними ресурсами для спільноти науковців максимізує користь для суспільства. У галузі цифрової інфраструктури це вже показало великі переваги. Очікується, що застосування цього принципу до відкритого наукового процесу покращить управління фінансуючими організаціями у співпраці із зацікавленими сторонами через такі механізми, як громадські консультації. Це збільшить уявлення про спільну власність на інфраструктуру. Це також створить чіткі та недискримінаційні правила доступу, а також почуття спільної власності, що стимулює більш високий рівень участі, співпраці та соціальної взаємодії. У статті розглядається концепція відкритої науки. Представлено концепцію європейської хмари відкритої науки та її структуру. Згідно з дослідженням, було показано, що структура хмари відкритої науки включає доповнену реальність як платформу відкритої науки. Прикладом практичного застосування цього інструменту є загальний опис MaxWhere, розроблений угорськими вченими і являє собою платформу сукупностей окремих 3D-просторів
