Is LVM still used in a Cloud Infra ?
@EngrAbhishekRoshan
@EngrAbhishekRoshan 4 часа назад
Yes, LVM (Logical Volume Manager) can still be used in cloud infrastructures, though it depends on the specific cloud platform and use case. Flexibility and Customization: LVM is still valuable in cloud environments when users require more control over storage management. It provides flexibility in resizing volumes, creating snapshots, and managing storage across multiple disks, which can be useful in custom VM setups or self-hosted cloud solutions. Cloud Storage vs. LVM: Most modern cloud platforms (like AWS, Azure, or GCP) provide their own block storage solutions (e.g., AWS EBS, Azure Managed Disks) with similar features to LVM, such as volume resizing and snapshots. As a result, these cloud-native solutions might reduce the need for LVM. Hybrid and On-Premise Scenarios: In hybrid or on-premise cloud infrastructures where cloud and physical servers coexist, LVM is still frequently used, especially for managing local storage in on-premise servers. Containerized Environments: In some containerized or Kubernetes environments, storage orchestration frameworks (like Ceph, LVM-based persistent volumes) still use LVM to manage disk space efficiently.
