A presentation given at Samvera Connect 2018 described thus, An overview of modern front-end UI component architecture and patterns. Will showcase case studies in development and implementation decisions in Avalon Media System (platform, React/Redux application built on top of Hyrax in AWS). Will make a case for why UI component architecture is important in community-driven, open-source development, how it can directly benefit the Samvera community moving forward.

A presentation given at Samvera Connect 2018 described thus, Despite widespread interest in Hyrax, Samvera’s new flagship repository solution, there is a dearth of documentation about how to run a production instance. We’ll cover the lessons we’ve learned from a year of building and hosting Hyrax, including our new project checklist, logging and monitoring practices, and data migration paths. DCE has been hosting a Hyrax based ETD repository for Emory University for 12 months. We've made a lot of discoveries and improvements since we launched. We'll be sharing our learnings and best practices for running Samvera Based repositories including, and * Infrastructure as code (esp. ansible for configuration management) * Monitoring using open-source and commercial tools (nagios, ok computer, splunk, pingdom, honeybadger) * Maintenance, Upgrades, and Testing A video recording of this session is available at the 'Related URL' below.
Over the past two years, Northwestern University Libraries has moved its repository infrastructure and applications to Amazon Web Services. Our initial solution, presented at Samvera Connect 2017, involved AWS CloudFormation, several different deployment platforms, and a lot of manual intervention. In our second phase, we have adopted a fully automated build/configure/deploy system to stand up Fedora, Solr, PostgreSQL, Redis, a Cantaloupe IIIF server, an Avalon Media System instance, a secure CloudFront streaming media distribution, and two Hyrax applications using Terraform, Docker, AWS Elastic Beanstalk, and a whole bunch of homegrown tools and hacks. This presentation will provide an overview of our current system, and hopefully jumpstart some discussions of how these tools can be adopted, standardized, and reused among other members of the Samvera community.

This presentation aims to explore the possible integration of Samvera digital object repositories with additional web services using message brokers. There have been cases in which it is necessary to synchronize content updates between repositories and additional library systems such as library catalogs or digital exhibit publishing software. Within this context, developers may benefit by exploring architectural pattern in which a dedicated message broker receives asynchronous notifications of repository content updates, new ingestions, and deletions. In response to having received these messages, the broker may then broadcast these events to other listening library systems. The library systems then may reindex or update their own content accordingly. A conceptual overview of this architectural pattern shall be provided, followed by an overview of an implementation local to the systems within the Princeton University Library (synchronizing content between implementations of Valkyrie and Spotlight using RabbitMQ). The outcome of this presentation would be to identify other Samvera adopters who may also be utilizing message brokers, with the ultimate aim of determining whether or not this approach would be beneficial to a larger number of community members.
