Kakao Enterprise said on the 2nd that it participated in 'OpenInfra Day Korea (KCDxCephxOpenInfra Day Korea 2026)' and shared know-how on optimizing Kakao Cloud storage.
Park Chan-young, manager of Kakao Enterprise's IAM/Storage Development Team, gave a presentation titled 'BlueStore Optimization That Is Not Shaken by Disk Utilization.'
Kakao Cloud said it uses the open-source distributed storage platform Ceph and BlueStore to ease bottlenecks that cause disk fragmentation and stably increase disk utilization.
Kakao Enterprise said on the 2nd that it participated in 'OpenInfra Day Korea (KCDxCephxOpenInfra Day Korea 2026)' and shared know-how on optimizing Kakao Cloud storage. This year's OpenInfra Day Korea was co-hosted by 3 communities: 'Kubernetes,' 'Ceph,' and OpenInfra. 'Kubernetes' is a standard for cloud-native technology, 'Ceph' is an open-source distributed storage platform, and OpenInfra leads open infrastructure technologies.
At the event, Kakao Enterprise introduced operational cases for large-scale data processing and stable service delivery. The presentation focused on storage optimization experiences that improved disk utilization in large-scale data processing environments while maintaining and enhancing service stability and user experience. Park Chan-young, manager of Kakao Enterprise's IAM/Storage Development Team, gave a presentation titled 'BlueStore Optimization That Is Not Shaken by Disk Utilization.'
In the presentation, Manager Park shared examples of improving disk utilization and enhancing service stability and user experience. Kakao Enterprise said it responded to the 'surging memory prices' through open-source-based storage optimization.
Park said that, amid recent surges in NAND flash memory prices and recent SSD price increases, many companies are trying to improve the efficiency of memory resource utilization and disk resource utilization. He explained that Kakao Enterprise is also responding to the growing need for cloud service operations through resource efficiency improvements.
However, Kakao Enterprise explained that in cloud operations, rising disk utilization is accompanied by the problem of disk fragmentation. Disk fragmentation refers to a state in which related data is stored non-contiguously, free space is stored non-contiguously, and data is distributed across multiple locations on the disk, adding that there are limits due to increased latency caused by disk fragmentation.
Accordingly, Park said Kakao Enterprise has turned to open source to promote smoother storage services for Kakao Cloud users. He explained that the company is taking a preemptive response by easing bottlenecks that cause disk fragmentation and securing low latency.
Kakao Cloud said it uses the open-source distributed storage platform Ceph and BlueStore to overcome these limitations. Through this, it said it alleviates bottlenecks that cause disk fragmentation and stably increases disk utilization.
Park also explained that in Kakao Cloud's block storage service, metadata location information is written and modified just as frequently as original data is written and modified. Accordingly, the company applied an approach similar to separately splitting the metadata area from the existing hard disk, and said it applied a partitioning technique that separates the actual original data area and metadata area to a single SSD.
