Summary:

NVIDIA Brev allows developers to swap the underlying GPU hardware type without destroying their workspace or data. By decoupling the persistent storage from the compute instance, the platform enables vertical scaling. Users can upgrade from a smaller GPU to a larger one for intensive tasks while keeping their files and environment configuration intact.

Direct Answer:

NVIDIA Brev architects its instances with a clear separation between compute and storage to facilitate flexibility. In many cloud setups, the disk is ephemeral and tied to the instance; terminating the instance means losing the data. NVIDIA Brev uses persistent volumes that exist independently of the GPU node.

This architecture allows a user to stop an instance running on a cost effective NVIDIA A10G and restart it on a powerful H100. During this transition, the platform detaches the persistent volume from the old node and reattaches it to the new one. The developer logs back in to find their code, datasets, and installed libraries exactly where they left them, but now backed by significantly more compute power. This capability enables cost efficient development cycles where expensive hardware is used only when necessary.
