# 1. Azure Pre-requisites

## Overview

The Azure Kubernetes Service (AKS) is one of the Azure services for deploying, managing and scaling any distributed and containerised workloads. Here we can provision the AKS cluster on Azure from the ground up using [**Terraform**](https://www.terraform.io/intro/index.html) **(**infra-as-code) and then deploy the DIGIT platform services as config-as-code using [**Helm**](https://helm.sh/docs/).

## **Pre-requisites**​

1. Azure subscription: If you don't have an Azure subscription, create a [free account](https://azure.microsoft.com/free/?ref=microsoft.com\&utm_source=microsoft.com\&utm_medium=docs\&utm_campaign=visualstudio) before you begin.
2. Install Azure [CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
3. Configure Terraform: Follow the directions in the article, [Terraform and configure access to Azure](https://docs.microsoft.com/en-us/azure/developer/terraform/get-started-cloud-shell)
4. Azure service principal: Follow the directions in the Create the service principal section in the article, [Create an Azure service principal with Azure CLI](https://docs.microsoft.com/en-us/cli/azure/create-an-azure-service-principal-azure-cli?view=azure-cli-latest). Take note of the values for the appId, displayName, password, and tenant.
5. Install [kubectl](https://kubernetes.io/docs/tasks/tools/) on your local machine, which helps you interact with the Kubernetes cluster.
6. Install [Helm](https://helm.sh/docs/intro/install/), which helps you package the services along with the configurations, environments, secrets, etc, into [Kubernetes manifests.](https://devspace.cloud/docs/cli/deployment/kubernetes-manifests/what-are-manifests)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digit.org/platform/guides/installation-guide/infrastructure-setup/azure/1.-azure-pre-requisites.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
