Increasingly we ask how sustainable Science Gateways are. A small number of such platforms garner large audiences, while the long tail is significantly smaller. It is challenging for large platforms to reach the point of sustainability, let alone for smaller platforms. A series of tactics help to increase such chances: lowering barriers to using the platform's resources, providing diverse functionality to support a large portion of the scientific enterprise, and using analytics to drive user engagement. Still, many find that when funding expires, keeping the platforms vibrant is too demanding. Further steps are being taken by the HUBzero® group and MyGeoHub.org to assist with sustainability. MyGeoHub.org is a science gateway powered by HUBzero that unites many communities using geospatial data, and which faces the challenge of sustaining its member communities. MyGeoHub hosts multiple research projects on a single HUBzero instance to lower the cost to individual projects. Projects share the gateway's common capabilities and the underlying hardware and other connected computing resources, and continued maintenance of their sites even after initial funding has run out, allowing time to acquire new funding. MyGeoHub has hosted projects for hydrologic modeling and data sharing, plant phenotyping, global and local sustainable development, climate variability impact on crops, and modeling of industry processes to improve reuse and recycling of materials. The shared need to manage, visualize and process geospatial data across the projects has motivated the Geospatial Data Building Blocks (GABBs) development, funded by NSF DIBBs. GABBs provides a barrier lowering interface to upload geospatial data and visualize them on maps, or "open with" tools that directly load the data in a seamless workflow. It also makes available libraries and APIs for rapid development of geospatial applications without requiring GIS programming expertise. GABBs can be added to an existing HUBzero site through an automated installation process. Similarly, HUBzero has established OneSciencePlace.org to host many HUBzero hubs when funding expires. With efforts like MyGeoHub and OneSciencePlace, an enabling platform is provided where the long tail of online science communities can band together to solve the sustainability problem.
