Globus platform services enable developers to create applications that leverage the Globus identity, profile, file transfer, and data sharing capabilities. Services currently available to developers include Globus Auth and Globus Transfer, as well as a number of web helper pages to accelerate application development.
Research applications often require sophisticated data management capabilities, for example to move large amounts of data between acquisition, storage, analysis and archival. However, doing so efficiently and reliably is often a difficult undertaking, requiring significant expertise to maximize available bandwidth, restart transfers that fail (due to network unreliability), validate that files have been transferred correctly, and securely transfer data between resources with different security configurations. Globus Transfer addresses these challenges by providing an easy to use "fire-and forget" data transfer mechanism that can be integrated by developers into their own applications.
Globus Transfer provides high performance, secure, third-party data movement and synchronization between endpoints, as well as in-place sharing of files directly on existing storage systems. Globus Transfer handles all the difficult aspects of data transfer, allowing application users to easily start and manage transfers between endpoints, while automatically tuning parameters to maximize bandwidth usage, managing security configurations, providing automatic fault recovery, and notifying users of completion and problems. With in-place sharing of data, researchers can share large datasets directly from their existing storage repositories on which the data resides.
Developers can leverage Globus Transfer to provide a high-performance and reliable upload or download mechanism for large (or small) datasets. This allows application users to asynchronously start uploads or downloads and rely on Globus Transfer to ensure the data is moved efficiently and reliably. By integrating Globus Transfer into an application, developers gain access to over 10,000 Globus endpoints.
Explore the Globus Platform
Globus Auth is a foundational identity and access management platform service designed to address unique needs of the science and engineering community. It serves to broker authentication and authorization interactions between end-users, identity providers, resource servers (services), and clients (including web, mobile, desktop, and command line applications, and other services).
Globus Auth thus makes it easy, for example, for a researcher to authenticate with one credential, connect to a specific remote storage resource with another identity, and share data with colleagues based on another identity. By eliminating friction associated with the frequent need for multiple accounts, identities, credentials, and groups when using distributed cyberinfrastructure, Globus Auth streamlines the creation, integration, and use of advanced research applications and services. Globus Auth builds upon the OAuth 2 and OpenID Connect specifications to enable standards-compliant integration using existing client libraries. It supports identity federation models that enable diverse identities to be linked together, while also providing delegated access tokens via which client services can obtain short term delegated tokens to access other services.
Many research communities have adopted Globus Auth to facilitate access to their resources and services, including the JetStream cloud, XSEDE, NCAR's Research Data Archive, and FaceBase.
Web Helper Pages
The Globus platform provides several web helper pages to enable use of common Globus functions within your web applications. Web helper pages simplify integration by allowing you to embed endpoint browsing, group selection, and login/logout pages into the application workflow with minimal code. After the user performs their action in Globus, the flow will redirect the user back to the application. For example, the endpoint selection page allows users to preselect a source endpoint and path. The user is then presented only with a destination selection interface to transfer a datasets. This approach provides a simple way for developers to use advanced Globus Transfer functionality without having to develop their own user interfaces.
