Kubernetes and its ecosystem provide appropriate abstractions and tools for composing heterogeneous resources into a tailored platform for a specific mission or audience.<div class=""><br class=""><div class="">In this talk we present the Center for Astrophysics | Harvard & Smithsonian Research and Development effort to provide a multi-wavelength science platform catered to scientists across departments and wavelength domains. The effort is aimed at integrating heterogeneous data using IVOA standard protocols, as well as providing a platform for bringing astronomer's science close to the data, in preparation for the ambitious vision of enabling Peta-scale Astronomy through missions currently being developed at the Center for Astrophysics. One of the Nexus R&D project's goal is to maximize reuse of existing tools and services. The Vera Rubin Science Platform (RSP) provides a set of tools and services in a generalized and extensible framework that offers such flexibility, while also reusing software from other IVOA members. As the first attempt at reusing the RSP framework for a different mission, the CfA-Nexus R&D project offers a unique perspective on how to generalize the abstractions in the RSP Phalanx project and how to streamline the development and deployment of IVOA compliant services along with powerful cloud-based computational resources. We will present the lessons learned in developing and deploying the CfA Nexus R&D prototype, with a focus on using the RSP as a generalized, extensible framework for generating custom Science Platform deployments for Astronomy.</div><div class=""><br class=""></div><div class="">~~~~~</div><div class="">A “what-if?” VO service implementation<div class=""><br class=""></div><div class="">Frossie Economou, Russ Allbery, Gregory Dubois-Felsmann<br class=""><br class="">For historical reasons, Rubin Science Platform had a mature web services architecture before starting to implement many of the required VO-compliant APIs. This made the gaps between the our common development patterns and the ones required to implement the standards particularly noticeable. We have talked about these issues before in the IVOA context (see also <a href="http://sqr-063.lsst.io" class="">sqr-063.lsst.io</a>) but sometimes these arguments come across as theoretical, or can end up being dominated by format arguments (e.g., xml vs json). In order to demonstrate more concretely the issues we have raised, we have done a what-if implementation alongside our standard compliant SODA service to highlight some of the divergence with current web services practice. We would like to prompt a discussion on how the standards can change not to solve any specific concern as a one-off, but in order to be able to evolve again, and again.<br class=""></div></div><div class=""><br class=""></div><div class=""><br class=""></div></div><div class="">
