Developed per-VM volumes support in the ydb-platform/nbs repository’s CSI driver, enabling storage volumes to be scoped and managed at the individual virtual machine level. This work involved refactoring volume and instance ID logic to tightly associate storage resources with specific VMs, enhancing isolation and reducing cross-VM risk in virtualized environments. The implementation updated client ID generation to reflect VM context, laying the foundation for VM-aware storage policies and improved governance. Leveraged Go programming, cloud storage concepts, and virtualization expertise to align the codebase with evolving infrastructure needs. No major bugs were reported during this focused feature development period.
Monthly performance summary for 2024-11: Implemented per-VM volumes support in the CSI driver for ydb-platform/nbs, with VM-scoped volume IDs and VM-context client IDs, enabling improved storage isolation and VM-aware management in virtualized environments. The change is tied to commit 5f1c3898df46c14e712fc80c28c39ac17a4da649 ("Support per-VM volumes (#2361)"), and introduces volume/instance ID refactors to associate storage with specific VMs. Major bugs fixed: none reported in this period. Overall impact: provides VM-specific storage isolation, reduces cross-VM risk, and lays the groundwork for VM-aware storage policies. Technologies/skills demonstrated: CSI driver development, ID refactoring (volume IDs, instance IDs), updated client ID generation to VM context, codebase alignment for ydb-platform/nbs.
