The Open Grid Forum (OGF) is a leading standards development organization for cloud, grid, and distributed computing. OGF has developed many relevant standards over its history dating back to 2001. These standards include specifications for identity management, job submission, data transfer, service agreements, and cloud computing interfaces. OGF actively collaborates with other standards bodies and its standards see widespread adoption in both research and industry implementations of distributed computing infrastructure.
Introduction to the Open Grid Forum community and the document production process, as well as several primary application arenas for OGF specifications, given at the co-located International Conference on Cloud and Autonomic Computing (CAC 2014), IEEE International Conference on Self-Adaptive and Self-Organizing Systems (SASO 2014) and the IEEE International Conference on Peer-to-Peer Computing (P2P’14) conferences, September 8-12, 2014 at Imperial College in London, UK.
Invited talk on Open Grid Forum standards, focusing specifically on the current status of the Open Cloud Computing Interface (OCCI), given at the US National Institute of Standards and Technology Cloud Computing Forum and Workshop VIII, July 7-10, 2015.
Overview and introductory remarks for the OGF sessions held May 21-22, 2015 co-located with the European Grid Initiative 2015 conference that took place the week of May 18-22, 2015 in Lisbon, Portugal. For details, see https://www.ogf.org/ogf/doku.php/events/ogf-44
OCCI - The Open Cloud Computing Interface – flexible, portable, interoperable...Alan Sill
The Open Cloud Computing Interface (OCCI) specification set defines a general protocol and API applicable to many different cloud resource management tasks.
OCCI began as a remote management API for IaaS model based Services, allowing for the development of interoperable tools for common tasks including deployment, autonomic scaling and monitoring. It has since evolved into a general-purpose flexible RESTful API framework with a strong focus on integration, portability, interoperability and innovation while still remaining highly extensible.
OCCI is suitable to serve many other models in addition to IaaS, including e.g. PaaS and SaaS. The current release (v1.1) of OCCI has achieved a high degree of adoption and implementation in production in a wide variety of languages, projects, software products and application areas.
The OCCI working group is in the process of developing an update of the OCCI specifications as version 1.2 with improvements that result from nearly four years of successful field experience. This version will be backwards compatible with v1.1 and will include:
- A new JSON rendering to accompany updates to the existing HTTP and text renderings.
- Minor updates of current OCCI core infrastructure model and specification.
- New extensions that will include PaaS support, notifications support and SLA support.
?In addition, the OCCI group is considering best methods for support of additional features, including monitoring, key management and security, interdomain networking and direct interface support for popular batch systems through the Distributed Resource Management Application API (DRMAA) standard.
Cloud Testbeds for Standards Development and InnovationAlan Sill
Invited talk given at the 2014 Chip-to-Cloud Security Forum "Advances in Securing Embedded, Mobile and Cloud Services and Ecosystems" in the seminar session on "Procurement, SLAs, and Standardisation on a Global Scale." In this talk, Dr. Sill reviews the history of cloud and grid computing, the formation and charter description for Phases I and II of the US National Institute of Standards and Technology (NIST) "SAJACC" working group, and brings the discussion up to date with an overview of current "DevOps"-oriented cloud standards and software interoperability hands-on testing efforts worldwide.
Overview of the US National Science Foundation Cloud and Autonomic Computing Industry/University Cooperative Research Center testbed activities on the US NSF Chameleon, Cloudlab and XSEDE resources.
The NSF CAC will use its industry/university connections to promote and foster open cloud standards & interoperability testbeds using internal and external resources.
Specific projects have been proposed and approved on two new NSF computer-science-oriented cloud “testbed as a service” resources, Chameleon and CloudLab, which have recently been funded to replace the FutureGrid project.
These testbeds will be open to all researchers who wish to cooperate with us on cloud interoperability, performance, standards or general cloud functionality testing within the context of the approved projects.
Both US domestic and international participants are welcome, as long as you’re willing to work on interoperability topics and share your results.
Opportunties for involvement in the CAC by commercial companies also exist, as described at http://nsfcac.org

Towards a Lightweight Multi-Cloud DSL for Elastic and Transferable Cloud-nati...Nane Kratzke
Cloud-native applications are intentionally designed for the cloud in order to leverage cloud platform features like horizontal scaling and elasticity – benefits coming along with cloud platforms. In addition to classical (and very often static) multi-tier deployment scenarios, cloud-native applications are typically operated on much more complex but elastic infrastructures. Furthermore, there is a trend to use elastic container platforms like Kubernetes, Docker Swarm or Apache Mesos. However, especially multi-cloud use cases are astonishingly complex to handle. In consequence, cloud-native applications are prone to vendor lock-in. Very often TOSCA-based approaches are used to tackle this aspect. But, these application topology defining approaches are limited in supporting multi-cloud adaption of a cloud-native application at runtime. In this paper, we analyzed several approaches to define cloud-native applications being multi-cloud transferable at runtime. We have not found an approach that fully satisfies all of our requirements. Therefore we introduce a solution proposal that separates elastic platform definition from cloud application definition. We present first considerations for a domain specific language for application definition and demonstrate evaluation results on the platform level showing that a cloud-native application can be transfered between different cloud service providers like Azure and Google within minutes and without downtime. The evaluation covers public and private cloud service infrastructures provided by Amazon Web Services, Microsoft Azure, Google Compute Engine and OpenStack.

Resumo
Em relatório publicado pelo Comitê Gestor da Internet no Brasil (CGI.br) em 2018, em termos de acesso à Internet por banda larga no Brasil, há uma ampla desigualdade entre as classes econômicas A/B (maior) e D/E (menor), fato evidenciado nas análises entre as áreas urbanas e rural. Além de evidenciar que cerca de 34% dos brasileiros ainda não possuem acesso à Internet, o relatório também explica que o acesso à Internet é um catalisador de desenvolvimento social, econômico e tecnológico: fato consagrado em diversas pesquisas internacionais e enfatizado pela organização Internet Society. Redes sem fio comunitárias têm se tornado um meio sustentável de promover meios acessíveis de conexão à Internet,tanto em áreas rurais remotas quanto em regiões urbanas densas. Em sua ampla maioria, redes sem fio comunitárias adotam a tecnologia wifi, no entanto apenas recentemente, devido ao desenvolvimento de tecnologias de código livre e de baixo custo, o padrão Long-Term Evolution (LTE) começou a ser explorado para estes fins. Logo, não há conhecimento na literatura acadêmica de estudos que busquem utilizar e melhorar o padrão LTE aplicado à redes sem fio comunitárias. Nesse escopo, esta proposta busca trazer conceitos inovadores de novos paradigmas de redes, Redes Definidas por Software (Software Defined Networks -SDN) e Virtualização de Funções de Rede (Network Functions Virtualization - NFV), para o desenvolvimento de redes LTE comunitárias. Por meio de uma metodologia ágil de testes,conceitos de SDN e NFV serão aplicados no desenvolvimento de mecanismos que realizem o gerenciamento inteligente de recursos de redes LTE comunitárias visando desempenho eficiente e tolerância a falhas robusta, i.e., a sustentabilidade da rede. Todos estes estudos serão feitos tendo por base um levantamento de características de redes sem fio comunitárias em operação no Brasil proposto para o início do projeto. Ao final, a execução desta proposta irá produzir um material didático elucidando as formas de modelamento, implantação, e manutenção sustentável de uma rede LTE comunitária nos moldes dos estudos realizados por esta proposta (i.e., com todos os dados, avaliações, metodologias, e protótipos). Este material será utilizado como base de uma proposta de implantação de uma rede LTE comunitária no Brasil junto ao programa "Beyond the Net" da Internet Society.

Comparing Open Source SDN Controllers, like OpenDaylight, OpenContrail, and ONOS is a challenge. Here, we’ll compare open source SDN Controllers. In a software-defined network (SDN), the SDN Controllers is the “brains” of the network. It is the strategic control point in the SDN network, relaying information to the switches/routers ‘below’ (via southbound APIs) and the applications and business logic ‘above’ (via northbound APIs).
Slides from my talk on R&D innovation projects around the Janet network for the HEAnet / Juniper Innovation Day, September 2015. I talk about some recent Janet R&D initiatives such as our Reach scheme for connecting industry to the network, our end to end performance initiative, and our Safe Share project for secure access to sensitive data by researchers - e.g. medical records. There is also a recap of some of our recent activity around equipment sharing, our shared data centre, connectivity and deals with major cloud providers.

Project Summary
The ever increasing performance of computer systems in general and IoT systems, in particular, delivers the capability to solve increasingly challenging problems, pushing automation to improve the quality of our life. This triggers the need for a next-generation IoT architecture, satisfying the demand for key sectors like transportation (e.g. self-driving cars), industry (e.g. robotization or predictive maintenance), and our homes (e.g. assisted living). Such applications require building systems of enormous complexity, so that traditional approaches start to fail. The amount of data collected and processed is huge, the computational power required is very high, and the algorithms are too complex allowing for the computation of solutions within the tight time constraints. In addition, security, privacy, or robustness for such systems becomes a critical challenge.
Future Internet: Managing Innovation and TestbedShinji Shimojo
Innovation is a big key word for ICT research and development. However, a road toward innovation is facing full of uncertainties and there are many obstacles. key elements to overcome these obstacles seems to be agile management of people, software and hardware. In addition, we think involvement of users in R&D will have much effect on the management of uncertainty in R&D. In this talk, I talk on our approach to this user involvement in JGN-X, an international future internet testbed and Knowledge Capital, Osaka, an smart city experimental testbed.

https://goo.gl/fSVnZy
http://dcs.iyte.edu.tr/ws/ppt/10/presentation.pdf
In distributed applications where the number of members in the cluster increases, the
separation of the consensus related operations at the hardware level is essential for the
following reasons:
1. At the operating system level, messages broadcast on the protocol stack cause latency.
2. It is necessary to increase the number of completed transactions in the communication of
distributed system components and on the network unit (throughput).
3. For devices with limited storage and CPU computing facilities that use embedded operating
systems such as IOT devices, it is also necessary to reduce the processing burden due to
"consensus" operations.
4. A common consensus communication model is needed for different applications that need
to work together in (BFT) distributed systems.
