+# Using GPU Workload in Welkin
+
+!!! elastisys "For Elastisys Managed Services Customers"
+    You can order a new Environment with GPU support by filing a [service ticket](https://elastisys.atlassian.net/servicedesk/).
+    Make sure to specify the need for GPU Nodes in "Additional information or comments".
+    If you are unsure, get in touch with your account manager.
+
+As the demand for AI, machine learning, and data science workloads grows, Kubernetes provides a flexible and scalable platform to manage these applications.
+In this guide, we'll focus on how to use GPU in the Welkin platform.
+
+> [!NOTE]
+> Not all infrastructure providers have support for GPU.
+> Check with the platform administrator to find out if your environment has support for GPU workload.
+
+## Deployment
+
+To use GPU resources in your cluster, you need to create a deployment that is using the resource `nvidia.com/gpu`.
+Here's an example of how to configure GPU resources for a Pod:
+
+```yaml
+apiVersion: v1
+kind: Pod
+metadata:
+  name: cuda-vectoradd
+spec:
+  restartPolicy: OnFailure
+  containers:
+  - name: cuda-vectoradd
+    image: "nvcr.io/nvidia/k8s/cuda-sample:vectoradd-cuda11.7.1-ubuntu20.04"
+    resources:
+      limits:
+        nvidia.com/gpu: 1
+```
+
+> [!NOTE]
+> If your cluster is using the cluster autoscaling feature and there's currently not enough resources, the autoscaler will create one for you.
+> It might take a couple of minutes for the new node to join the cluster and to install all the pre-requisites.
