Part three of a series of webinars providing an introduction to a variety of gateway platforms that can be used for building new gateways.
Building and operating an effective science gateway for the long term is harder than you think. This talk describes Apache Airavata and its growing ecosystem of software extensions that can be used to build science gateways. The Science Gateways Platform as a service (SciGaP.org) is a hosted version of Apache Airavata that is operated by the Cyberinfrastructure Integration Research Center (CIRC) at Indiana University. SciGaP makes building and operating gateways both easier and more sustainable. We review several example gateways in diverse research fields that are based on Apache Airavata and that use SciGaP.org services.
About Apache Airavata:
Apache Airavata is multi-tenanted middleware that manages the execution of scientific software and data transfers on XSEDE high performance computers, university clusters, and computational clouds; Airavata also tracks user sessions and metadata for gateway users so that they can review, clone/copy, search, and share metadata about computational experiments.
Apache Airavata is supplemented by additional open source projects reviewed in this presentation: Custos is security middleware that helps gateways manage user identities, resource access secrets, and groups; the Django-based reference portal framework for Airavata is a Web front end for gateways that can be used both out of the box and as a basis for extensive customization; and the Managed File Transfer service provides an abstraction layer that allows gateways to manage and transfer data distributed across multiple resources.

HUBzero Platform for Scientific Collaboration: Overview of the architecture, features, and sustainability
Presented by Nate Snodgrass, Program Manager, HUBzero®
Part two of a series of webinars providing an introduction to a variety of gateway platforms that can be used for building new gateways.
HUBzero® is an open source software platform for building powerful websites that host analytical tools, publish data, share resources, collaborate, and build communities in a single web-based ecosystem. Initially created by researchers in the NSF-sponsored Network for Computational Nanotechnology to support nanoHUB.org, the HUBzero® platform now supports science gateways from a variety of disciplines built from the HUBzero® platform with a collective of over 2 million visitors a year. In this webinar, the HUBzero® team will review the HUBzero® architecture and middleware with examples of different use-cases.
Answers to questions asked during the webinar
Feel free to contact email@example.com with questions.
Q: Are you looking at TAPIS (Agave) and/or Abaco for remote HPC services?
A: We have talked to folks at TAPIS and Airavata and are having continuing conversations about the possibilities.
Q: How does the HUBzero platform handle "static" gateway web pages? Can non-developers add/edit without having to redeploy the stack? Or do static pages need to go elsewhere?
A: Static pages are housed in a Hub, and administrators of the Hub can sign-in and edit pages via an editor. The access point is via a back-end login to manage these pages. For group pages, static pages available in the group space can be edited from the group by managers or users who have assigned roles to manage those pages.

Using Tapis: APIs for Portable, Reproducible High Performance Computing in the Cloud
Presented by Julia Looney, Software Engineer, Cloud & Interactive Computing, and Richard Cardone, Research Engineering/Scientist Associate, Web & Cloud Services, Texas Advanced Computing Center
Part one of a series of webinars providing an introduction to a variety of gateway platforms that can be used for building new gateways.
This webinar considers the challenges of running computationally intensive and high throughput applications in a reproducible, easy-to-use manner. To reach the widest audience, web-based applications tailored to specific domains provide gateways for different user communities. To avoid duplication of effort, there's a clear need for a middleware layer that mediates between those web applications and backend systems, such as supercomputers, cloud-based clusters, mass storage systems, and databases. Tapis fills this middleware need with a set of authentication, authorization, data transfer, job management, and function execution services that can span multiple data centers and manage batch, interactive, and streaming jobs. This webinar provides an overview of the recently announced, NSF-funded, Tapis project.
