Research often requires transferring large amounts of data among widely distributed resources including supercomputers, instruments, Web portals, local servers, HPC clusters and laptops/desktops. Traditional methods such as FTP and SCP are ill-suited to data movement on this scale due to poor performance and reliability, and custom solutions are costly to develop and operate. Globus Online is a new Software-as-a-Service solution that provides a robust, reliable, secure, and highly monitored environment for file transfers, with powerful yet easy-to-use interfaces. Globus Online simplifies large-scale data movement without requiring construction of custom, end-to-end systems. With Globus Online, the robust file transfer capabilities that were traditionally available only on the largest scale grid implementations are now accessible to all users
