The Emory Libraries implemented a second-generation preservation infrastructure in 2019 utilizing Hyrax 3, Fedora 4 and AWS, following a requirements gathering phase that included developing a preservation policy and a review of preservation community best practices. This presentation describes our solution design including locally-defined entities such as preservation workflows and events and FileSet expansion to support derivative files. We will also address implementation lessons learned while leveraging existing Samvera functionality and building new features to bridge gaps between existing framework components.

"what are we going to do about the cloud?" If only we had some kind of animal, recently retrofitted with Wings, that could live up there natively. Fear not, Hyraxes do that. This presentation tackles the what, why, and how of cloud native Samvera. What is the community doing and what are solution bundles supporting? Why should you be interested? Why should you contribute? How can you (yes, i'm looking at you developers, operations folks, repository managers, bosses) benefit? How can your repository make its home among the clouds?

This talk will outline the Surfliner code base, describe the GitLab monolithic source repository, and discuss the reasons behind choosing this model of source control management. It will include background on the systems and workflows used by the UC San Diego and UC Santa Barbara teams that make managing and working productively with a single repository feasible, in addition to a psychomachia-style discussion of the advantages and trade-offs of this approach.

A presentation given at Samvera Connect 2020 On-line described thus and After trying to navigate deployment, configuration, performance, and scaling issues of several different image servers and support infrastructure (Cantaloupe, Aware, Riiif, nginx, and SquidCache, to name a few), we decided to see if we could build something less general/configurable but far more suited to our use case and runtime environment. serverless-iiif started out as a bare bones, proof-of-concept demonstration of how a scalable, high-performance IIIF image server could be implemented in a small, inexpensive AWS Lambda function. Just over a year later, the project serves as the basis for high-volume IIIF services running in production at Northwestern University, Princeton University, the University of Notre Dame, and the Royal Pavilion & Museums, Brighton & Hove. This presentation will cover the project from its beginnings (as a small demo repository carved out of Northwestern's cloud repository infrastructure), through a number of forks, merges, performance enhancements, deployment improvements, and into production. We will also include performance benchmarks, current production stats, and some thoughts on future work. The 'Related URL' below links to a video recording of the session.

A presentation given at Samvera Connect 2020 On-line (originally titled 'Cloud storage service uploads for a Valkyrie repository') and described thus and This presentation aims to outline and discuss attempts throughout 2019 and 2020 to integrate an early pre-release of the BrowseEverything 2.0 component for supporting Google Drive file uploads into a Samvera repository. While this shall be restricted in scope for cases which were specific to the Princeton University Library and a Valkyrie-based repository Figgy, the hope is to encourage discussions regarding obstacles which were encountered and to aim to generalize the solutions which were discovered in this integration.

Northwestern University Libraries is currently running Samvera applications in production. Three of these are developed, maintained, and managed by the Repository & Digital Curation workgroup, * Arch, an Institutional Repository, based on Hyrax 2.4.1 * AVR, Northwestern's audiovisual repository, based on Avalon 6.3 * DONUT, the staff-facing ingest interface for the digital object repository, based on Hyrax 2.4.1 In developing and deploying these applications, we have encountered (and mostly overcome) numerous stumbling blocks relating to performance, scalability, customization, and assumptions about the deployment environment and infrastructure on which the apps will run. While we have found it possible to shoehorn the Samvera stack (as it exists today) into our Amazon Web Services cloud-based deployment environment, we have also started to investigate the rewards and compromises involved in taking a cloud-first approach to our next generation of tools. We have identified several basic tenets for this approach so far, * If AWS offers a native Software-as-a-Service (SaaS) solution for a particular problem, use it (e.g., choose ElasticSearch/Cloud Search over Solr) * Avoid virtual server instances that run 24x7 waiting for requests/work * Do not assume there is a local filesystem to work with * Optimize startup time so that units of work can be spawned and killed as needed * Constantly assess and reassess every unit of work for scalability, repeatability, and idempotence * Keep data portable and code adaptable, but don't over-stress about vendor lock-in In this presentation, members of the Repository Development & Administration Team will present on lessons learned from 7 years of working with Samvera, Avalon, and Hyrax, what the future holds for our next round of in-house development, and the opportunities & compromises our cloud-first approach creates regarding our use of and contributions to the larger Samvera community., and A presentation at Samvera Virtual Connect 2019 described thus

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.
