The European Grid Infrastructure (EGI) enables researchers to address novel scientific theories and create more knowledge, by providing access to state-of-the-art computer technology. Access to an e-infrastructure, such as EGI, is granted through a range of different user interfaces or gateways. The technical expertise of the user, as well as which resources are being targeted, will ultimately dictate which interface should be used.
This page aims to provide information about current interfaces that can be used by communities, as well as to provide details on the technologies underlying the interfaces.

A Science Gateway is a community-developed set of tools, applications, and data that are integrated via a portal or a suite of applications, usually in a graphical user interface, that is further customized to meet the needs of a specific community. Gateways enable entire communities of users associated with a common discipline to use national resources through a common interface that is configured for optimal use. Researchers can focus on their scientific goals and less on assembling the cyberinfrastructure they require. Gateways can also foster collaborations and the exchange of ideas among researchers.
A science gateway is a set of computational tools, applications, and data that is integrated and customized via an enterprise portal to meet the needs of a specific community. A science gateway enables community members to define and perform custom scientific/research scenarios. EGI science gateways are operated for and/or by European research communities and simplify access and interaction with the resources and services of the European Grid Infrastructure.

Science gateways are an emerging interface for communities to engage more actively with the e-infrastructure, by lowering the barrier that can exist between users and the evolving grid world. The success of bringing new communities, and sustaining current ones, relies heavily on the user-friendliness and robustness of the available interfaces. Otherwise, it will be mind-boggling for researchers and their lifelong commitment of producing knowledge will be lost.
The first steps in creating a gateway include deciding on the interface type and about the services to which a gateway will connect on the backend. You may choose to build a web-based user interface or a desktop application that is installed directly on the end-users' workstations. On the back end, the gateway may connect to only XSEDE services, or it may serve as a bridge to both XSEDE services and other community grids.

Using existing gateways
Empowering scientific communities with tools that enable them to make use of the European Grid Infrastructure resources in a user friendly, seamless and transparent way
Web-based user interfaces aim to lower the barrier that can exist between users and the evolving grid world. Portals are typically geared to specific users, applications and scientific use cases. These science gateways
Empowering scientific communities with tools that enable them to make use of the European Grid Infrastructure is important for the successful engagement of EGI with new users, while providing a continuous quality of service to current users.

These science gateways
Several national and community-specific teams/projects offer portals as well as underlying portal builder technologies in EGI.
With such a diversity it can be difficult to make a decision on which portal to use as a scientist, which portal builder technology to use as a portal developer.
Web-based user interfaces are an emerging interface for communities to engage more actively with the e-infrastructure. Again, the rule of thumb is to lower the barrier that can exist between users and the evolving grid world. The success of bringing new communities, and sustaining current ones, into this “cyber-jungle” relies heavily on the user-friendliness and robustness of the available interfaces.
can eliminate barriers of e-Infrastructure access while seamlessly integrating grids and the web.
EGI responded to this need with the setup of a "portal technology comparison table". The table provides a review of existing and reusable portals, portal developer frameworks, portlets and components that exist within EGI. The table helps scientific communities and their software teams identify solutions that best meet their needs and should be considered when accessing or building portals.
The questions that are used within the table to describe and compare the different portals and portal frameworks have been defined through an open process during December 2011 - January 2012. [[|]]
[[[../../../../index.php?title=Portal_Technologies&action=edit§ion=2|edit]]] Adding a new entry
New entries can be added to the table through this [LINK online survey]. The survey consists of two sections to collect basic and more detailed information about the technology to be added. If you wish to read the survey questions before filling the form please consult with [[../../../../../wiki/Portal_Technology_Questions|this page]]. The survey is managed by the EGI.eu User Community Support Team, who validate the received information and add entries to the below, publicly accessible table. If you register your portal in the table please also consider registering it in the EGI Applications Database. [[|]]

How to Turn Your Project into a Science Gateway
- Get an XSEDE allocation; Start-up and Educational allocations require only a one paragraph project description. For more information visit the Allocations section of the web site.
- Register your project as an XSEDE Gateway
- Build a portal
- Set up your developer accounts by Adding users to an existing allocation. Also, set up your Gateway community accounts.
Using Existing Gateways
Gateways are independent projects, each with its own guidelines for access. Most gateways are available for use by anyone, although they usually target a particular research audience. XSEDE Science Gateways are portals to computational and data services and resources across a wide range of science domains for researchers, engineers, educators, and students. Depending on the needs of the communities, a gateway may provide any of the following features:
- High-performance computation resources
- Workflow tools
- General or domain-specific analytic and visualization software
- Collaborative interfaces
- Job submission tools
- Education modules
See the List of Gateways, which is sortable by science domain, to explore the current XSEDE gateways projects.

Many scientists today routinely conduct simulations and run models using high performance computing (HPC) resources provided by national, regional and campus grid infrastructures, either directly logging into such resources or indirectly via web portals and other application client software, i.e. science gateways. Science gateways have proven to be an effective way of bringing HPC resources to a much larger user base.
