What is the primary function of a vSphere license?

The primary function of a vSphere license is to allow access to the features of VMware vSphere components. Licensing is essential in ensuring that users can utilize the various functionalities offered by the vSphere suite, which includes VM management, resource allocation, and advanced features like vMotion and DRS (Distributed Resource Scheduler). A valid license enables organizations to unlock and leverage the capabilities necessary for managing their virtualized environments effectively.

While technical support is important for addressing issues and providing assistance with VMware products, that is not the main purpose of the license itself. Additionally, backups of virtual machines and increasing storage capacity are operational tasks that may involve specific tools or services but are not directly related to the core function of licensing. The license specifically governs access to the features of the vSphere suite, making it crucial for users to ensure they have the appropriate licenses for their needs.
