What is a science gateway, and is it related to portals?

The terms "portal" and "science gateway" both refer to graphical user interfaces (GUIs) designed to make it easier to work with computers generally; they are often confused.

A portal is a general term for any system designed to facilitate your use of computer-based resources (typically implying some resource beyond your personal computer, and an interface other than the GUI provided by your computer's operating system). A common type is a web portal, a web site that provides personalized capabilities to its visitors. Web portals use a variety of middleware, hardware, and distributed applications to provide services from different sources.

The term "science gateway" refers to an interface designed specifically to support a particular type of scientific research, with an emphasis on supporting the entire scientific process from start to finish. Science gateways require considerable effort to create, and are typically designed to help an entire community of researchers use high-performance computing resources and advanced cyberinfrastructures to pursue common scientific goals.

The Extreme Science and Engineering Discovery Environment (XSEDE) develops science gateways for areas including severe weather prediction, astronomical observations, computational chemistry, genomics, and nanoscience.

For more about Extreme Science and Engineering Discovery Environment (XSEDE) Science Gateways, see the Science Gateways Overview and the list of current Science Gateways in the XSEDE User Portal. For information about registering and managing an XSEDE Science Gateway, see Gateways for principal investigators (PIs). For information about planning and designing an XSEDE Science Gateway, see The Role of the Developer.
