In cloud block store, indexing is on the critical path of I/O operations and typically resides in memory. With the scaling of users and the emergence of denser storage media, the index has become a primary memory consumer, causing memory strain. Our extensive analysis of production traces reveals...

Efficient cloud computing relies on high-performance Elastic Block Storage (EBS) services, where virtual disk (VD) image loading significantly affects user experience. While the commonly used "lazy loading" approach reduces cold-start time from minutes to sub-seconds, our trace analysis of around...
