+# DeepSpeed with Azure
+
+This tutorial will help you get started running DeepSpeed on [Azure VMs](https://azure.microsoft.com/en-us/services/virtual-machines/), support for [Azure ML](https://azure.microsoft.com/en-us/services/machine-learning/) will be coming soon!
+
+To help with launching Azure instances we suggest using the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/?view=azure-cli-latest). We have created several helper scripts to get you quickly started using DeepSpeed with Azure.
+ * Install Azure CLI on your local box: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli
+ * Alternatively you can use the Azure in-browser shell: https://shell.azure.com/
+
+ ## Create an SSH key
+ Generate a SSH key that will be used across this tutorial to SSH into your VMs and between Docker containers. `ssh-keygen` is the recommended way of doing this. Our scripts assume your key is located inside the same directory as the Azure scripts.
+
+ ## Azure Config JSON
+ Our helper scripts depend on the following a configuration JSON for deployment and setup. We have provided a simple example JSON (see: [azure_config.json](azure_config.json)) that sets up a basic environment with two VMs, see the example below.
+ ```json
+{
+  "num_vms": 2,
+  "location": "southcentralus",
+  "azure_sku": "Standard_NV6_Promo",
+  "ssh_private_key": "id_rsa",
+  "docker_ssh_port": 2222
+}
+ ```
+
+ ## Create Azure VMs
+ [./create_vms.sh](create_vms.sh) will create VMs with the Azure SKU you choose and in the region you specify in your config JSON. Feel free to customize your JSON to your desired region/SKU. This step will take a few minutes to complete while it sets up all of your VMs on Azure.
+
+ ## Setup VM environment to use DeepSpeed
+ [./setup_vms.sh](setup_vms.sh) will generate the MPI-style hostfile and SSH config that all of your VMs will use so that your Docker containers can talk to one another after they are setup.
+
+ ## Start the DeepSpeed docker container
+ [./setup_docker.sh](setup_docker.sh) will pull the DeepSpeed docker image on all VMs and start a container instance in the background. This will take several minutes since it needs to pull the entire Docker image.
+
+ ## Access VMs
+ [./azure_ssh.sh](azure_ssh.sh) will let you SSH into any of your VMs with this syntax: `./azure_ssh.sh <node-id> [command]`, the node-id is a number between [0, num_vms). This script will find the public IP address of your VM and use the SSH key you provided in the azure config JSON.
+
+## Access DeepSpeed container
+Everything should be up and running at this point, let's access the running DeepSpeed container on the first VM and make sure we can talk to the other containers in our setup. Let's complete the following steps:
+
+ * SSH into the first VM via: `./azure_ssh.sh 0`
+ * Change directories into the azure folder of this repo via: `cd ~/workdir/DeepSpeed/azure`
+ * Attach the running docker container via: `./attach.sh`
+ * You should now be able to ssh into any other docker container, the containers can be accessed via their SSH alias of 'worker-N' where N is the VM number between [0, num_vms). In this example we should be able to successfully run `ssh worker-1 hostname`.
