A recording of a presentation at Samvera Connect 2018 described thus, prototyping a core component of our new architecture to be horizontally scalable, designing a new architecture for our digital library with a wide ranging set of requirements and users, Stanford University Library has a robust digital library system called the Stanford Digital Repository. This repository holds a little under 500 TB of materials in preservation, and a little less than that for online access, from our cultural heritage digitization efforts and institutional repository outputs. These materials are managed across 90+ codebases serving a variety of functions from self-deposit web applications, to a nearly 10 year old parallel processing framework, to a digital repository assets publication mechanism leading into our Blacklight, Spotlight, and Geoblacklight applications - among other services and needs. At the core of this system is a Fedora 3 store. With Fedora 3 now end-of-lifed, and our system suffering from limited to no horizontal scalability options, we’re revisiting our system and architecture. We are writing it from the start with a goal to have data-forward, distributed microservices and some event-driven processing components. TACO, our new core management API, is the heart of this new architecture, and is currently being developed as a prototype. This talk will walk through the process of analysing our current system via a dataflows analysis, then planning how to create ‘seams’ in our current system to migrate towards our new system in an evolutionary fashion instead of a turn-key migration.

At Stanford libraries we've run hundreds of virtual machines to support dozens of applications. We've found the cost and complexity of patching and maintaining these machines to be untenable. We believe that a serverless infrastructure is our future and so we are using AWS Fargate (Elastic Container Services) and Lambda architecture to reduce our maintenance burden. We will explain the AWS offerings in this space, explain how we can set up a simple distributed system, and point out pitfalls that we've experienced. and A video recording of a presentation at Samvera Connect 2018 described thus

A recording of a panel presentation at Samvera Connect 2018 described thus and In this panel we will briefly discuss the current landscape of needs and reasons for users to consider moving from an established repository, and the challenges facing users of a variety of platforms, both cultural and technological. We will also consider work currently underway such as "Bridge to Hyku", a grant-sponsored project empowering Content DM users to migrate, successes in DSpace-to-Samvera migration and what's on the horizon for BePress. In discussing these challenges, we hope to present the Samvera Community with an opportunity to grow the portfolio of users and create the potential for standards and teams to assist those who wish to be a part of the Samvera Community.

A recording of a presentation at Samvera Connect 2018 described thus and Panelists from Duke University, Indiana University, and the University of Michigan will share their experience of developing a Research Data Repository based on Hyrax 2. They will discuss what worked out-of-the-box, what was customized, future directions, lessons learned to date from working together, and contributing back to the Hyrax community. Institutions’ efforts include data migration, accessibility testing, branding, community outreach, curation workflows, and overcoming the challenges associated with large datasets.
