  • Efficient development and deployment of Hydra projects using Vagrant

    Description:
    A presentation at Hydra Connect 2016 described thus, In this presentation, we will present a software development and deployment process that we have developed at Virginia Tech. We have used this procedure to develop several Hydra projects for University Libraries services at Virginia Tech and have also used it to conduct interviews for Ruby and Rails developers. We implemented a central vagrant box to facilitate the development and deployment processes. Using this vagrant box gives us many benefits, and 1. Code immediately. Our software engineers can focus on coding without worrying about software installation. 2. Unified development environment. All developers do their work in the same, consistent development environment. 3. Development of multiple projects simultaneously. Developers can work on multiple projects in parallel, switching between project environments in just a few minutes. 4. Minimal differences between development environments and production environment. After we finish implementation, we can quickly deploy our applications into a cloud environment (e.g. AWS and OpenStack) that is highly consistent with our development environments. We will present and demonstrate our hands-on experience on how we use a single vagrant box with different GitHub repositories to develop multiple Hydra applications in detail, including Sufia, GeoBlacklight, Fedora, Solr, Vagrant, AWS, and OpenStack. An audio recording of the session is available for download below.

  • Samvera and Fedora 4 Performance

    Description:
    A presentation given at Connect 2017 described thus and In this presentation, we present Fedora 4’s performance in different use cases. These use cases are the most general use cases that were developed by the Fedora 4 performance team. We compare the performance between different versions of Fedora 4 and demonstrate the improvement between these versions. We will also describe the procedures of these performance experiments and demonstrate the software we use (Ansible, AWS, and JMeter). Our performance experiments are conducted in the AWS ecosystem, and we use an R graph tool to visualize the JMeter result. With the AWS grant, we can do many different performance experiments in many scales. Moreover, it is easy to repeat and verify the performance results using AWS. The Fedora 4 performance team wants to know more about the Samvera community’s interests related to the Fedora 4 performance. We plan to gather more use cases from the Samvera community, including middleware such as Solr, Camel, and Fuseki, etc. We can investigate, explore issues, and continue enhancing the future of Fedora 4.
