The Data Science Infrastructure HOKUSAI SailingShip (HSS) began operations
in October 2020 and is scheduled to end in May 2026.
We are currently considering a successor system.
HSS is a private IaaS primarily designed for storing, sharing,
and analyzing data related to research, and is widely used by over 100 projects.
However, we believe there is untapped potential demand,
and aim to address this by developing a more user-friendly system.

To ensure the next HSS becomes a widely adopted system within RIKEN,
we are soliciting feedback from across the organization.
Even if you do not plan to use the next HSS, your input will be valuable for future reference.
We kindly request your participation in this survey.

• Response deadline: July 7, 2025
• Questionnaire form (RIKEN Portal)：Questionnaire for the introduction of the next HSS

Reference: Data Science Infrastructure HSS TOP

Please note that the introduction of the next HSS has not been decided,
and we expect to extend the operation of HSS for several months.
