# Overview

Pods in Lium represent individual GPU rental units that users can lease for their computational needs. Each pod is a containerized environment that provides secure, isolated access to GPU resources through the Bittensor subnet infrastructure.

Security depends on the underlying machine you choose. CVM-enabled machines provide stronger isolation for sensitive workloads, while non-CVM machines may allow the GPU provider to access the rented pod. Review the [Create Pod guide](./create-pod.md) before deployment, and read the [Confidential Virtual Machine (CVM) guide](../providers/nodes/cvm.md) if you need the full security model.
