Description
The KEK Central Computer System (KEKCC) is a computer service and facility that provides large-scale computer resources, including Grid and Cloud computing systems and essential IT services, such as e-mail and web services.
Following the procurement policy for the large scale computer system requested by the Japanese government, we replace the entire KEKCC every four or sometimes five years. The current system has replaced the previous system and has been in operation since September 2020, and decommissioning will start in early 2024.
During about 20 months of operation in the current system, we have decommissioned some legacy Grid services, like LFC, and migrated some Grid services to the newer operating system, CentOS7. In this talk, we would like to share our experiences and challenges regarding Grid services introduced in the KEKCC. Also, we pick up some issues to be addressed in the future.
