    BOKU-IT BOKUdrive – Sync and Share Online Storage At https://drive.boku.ac.at members of the University of Natural Resources and Life Sciences have access to a modern Sync and Share online storage facility. The data of this online storage are stored on servers and in data centers of the University of Natural Resources and Life Sciences. The solution is technically based on the free software "Seafile". Users can access their data via a web interface or synchronize via desktop and mobile clients. Seafile offers similar features to popular online services such as Dropbox and Google Drive. The main difference is that Seafile can be installed as open source software on its own servers and its data is stored completely on servers and in data centers of the University of Natural Resources and Life Sciences.

  • Openstack Designate
    OpenStack Designate Stephan Lagerholm Graham Hayes What is OpenStack? OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through RESTful web services. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2012, it was managed by the OpenStack Foundation (Source: Wikipedia) 2 Designate • Designate started as a project to maintain DNS infrastructure for OpenStack Users. It was an ecosystem project that was in production at both HP’s and Rackspace’s clouds. During 2015, Designate was moved into OpenStack Foundation and in 2017 it became a registered trademark. • Designate is providing API, CLI and a Graphical User interface so that OpenStack Users can setup and make changes to DNS data. The zones are thereafter exposed to secondary DNS servers via Zone Transfers. • Officially Bind 9.X and PowerDNS 4.X is supported although other DNS servers are known to work too. Most resource Record Types such as A, AAAA, PTR, CNAME, NS, MX, etc are supported 3 Producer Producer Backend Producer Producer Producer Worker Customer Facing API Central DNS Servers Standard XFR Secured by TSIG Nova / DB Mini

  • File Synchronization As a Way to Add Quality Metadata to Research Data
    File Synchronization as a Way to Add Quality Metadata to Research Data Master Thesis - Master in Library and Information Science (MALIS) Faculty of Information Science and Communication Studies - Technische Hochschule Köln Presented by: Ubbo Veentjer on: September 27, 2016 to: Dr. Peter Kostädt (First Referee) Prof. Dr. Andreas Henrich (Second Referee) License: Creative-Commons Attribution-ShareAlike (CC BY-SA) Abstract Research data which is put into long term storage needs to have quality metadata attached so it may be found in the future. Metadata facilitates the reuse of data by third parties and makes it citable in new research contexts and for new research questions. However, better tools are needed to help the researchers add metadata and prepare their data for publication. These tools should integrate well in the existing research workflow of the scientists, to allow metadata enrichment even while they are creating, gathering or collecting the data. In this thesis an existing data publication tool from the project DARIAH-DE was connected to a proven file synchronization software to allow the researchers prepare the data from their personal computers and mobile devices and make it ready for publication. The goal of this thesis was to find out whether the use of file synchronization software eases the data publication process for the researchers. Forschungsadaten, die langfristig gespeichert werden sollen, benötigen qualitativ hochwertige Meta- daten um wiederauffindbar zu sein. Metadaten ermöglichen sowohl die Nachnutzung der Daten durch Dritte als auch die Zitation in neuen Forschungskontexten und unter neuen Forschungsfragen. Daher werden bessere Werkzeuge benötigt um den Forschenden bei der Metadatenvergabe und der Vorbereitung der Publikation zu unterstützen.

For the example, the base we will create will be another Clouder. Odoo installation This guide will not cover the Odoo installation in itself, we suggest you read the installation documentation on the official website. You can also, and it’s probably the easier way, use an Odoo Docker image like https://hub.docker.com/ _/odoo/ or https://hub.docker.com/r/tecnativa/odoo-base/ Due to the extensive use of ssh, Clouder is only compatible with Linux. Once your Odoo installation is ready, install the paramiko, erppeek and apache-libcloud python libraries (pip install paramiko erppeek apache-libcloud), download the OCA/Connector module on Github and the Clouder modules on Github and add them in your addons directory, then install the clouder module and clouder_template_odoo (this module will install a lot of template dependencies, like postgres, postfix etc...).

Virtualisation is used to hide information like physical location and architectural details of the resources from the user. Eucalyptus is an open-source software framework for cloud computing implementing Infrastructure as a Service (IaaS). It is tailored for the use in the research community. Users can run and control virtual machine instances on a variety of physical resources found within academic settings. 2 Requirements Eucalyptus can be installed via the Ubuntu Enterprise Cloud, introduced in Ubuntu 9.04 [3]. The following installation instructions are based on Ubuntu 9.10 Server edition. In terms of hardware requirements recommended minimum specification is a a dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. 1 3 Installation procedure • Ubuntu 9.10, server edition • dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. • port 22 needs to be open for admins (for maintenance) • port 8443 needs to be open for users for controlling and sending requests to the cloud via a web interface 3 Installation procedure The installation instructions in this manual closely follow those given on the \Ubuntu Enterprise Cloud" homepage [2], with some remarks regarding installation from scratch via the Ubuntu 9.10 server edition.
