# Auto-Scaling for Access Nodes

Note for auto-scale version 1

Auto-scale version 1 is deprecated in older versions of Commvault. Commvault Platform Release 11.44 supports only auto-scale version 2. If you have upgraded to Commvault Platform Release 11.44, disable the auto-scaling option at the hypervisor level after you configure auto-scale version 2.

Auto-scaling for Azure access nodes optimizes performance and resource utilization, particularly during large-scale operations. The system dynamically provisions access nodes within a region only when required, ensuring that resources are automatically powered down and decommissioned once the workload completes.

This process is orchestrated through the Scale Manager, which intelligently automates provisioning, scaling, and cleanup. It reduces operational overhead, lowers compute costs, and enhances system efficiency. Additionally, it provides a robust foundation for elastic scalability across cloud environments, ensuring seamless and reliable operation at scale.

Auto-scaling can be used for the following operations:

- Backup and restore

- File indexing

- Replication

- Threat Scan

Multi-tenant environments

In multi-tenant environments:

- Service providers can offer auto-scaling as a service.
- Tenants can either use their service providers' scaling profile configuration or configure their own scaling profile.
