<strong><%= modified_date %></strong>

This topic describes the prerequisites and resource requirements for installing <%= vars.product_full %> on Microsoft Azure.

##<a id='prerequisites'></a> Prerequisites

Before you install <%= vars.product_short %>, you must satisfy Azure subscription requirements and install one of the following:

* Ops Manager <%= vars.ops_man_version_2_5 %> 
* Ops Manager <%= vars.ops_man_version_2_6 %> 

<p class="note"><strong>Note:</strong> You use Ops Manager to install and configure <%= vars.product_short %>. Each
version of Ops Manager supports multiple versions of <%= vars.product_short %>. To confirm that your Ops Manager version
supports the version of <%= vars.product_short %> that you install, see <a href="release-notes.html"><%= vars.product_short %> Release Notes</a>.</p>

###<a id='resources'></a> Subscription Requirements

For <%= vars.product_short %> and Kubernetes services to run correctly, you must have at least a `standard` subscription
tier.

###<a id='ops-man'></a> Install and Configure Ops Manager

To install an Ops Manager version that is compatible with the <%= vars.product_short %> version you intend to use,
follow the instructions in the corresponding version of the Ops Manager documentation.

<p class="note"><strong>Note</strong>: The topics below provide the Terraform procedures for deploying Ops Manager on Azure, not the manual procedures. The Terraform procedures are the currently supported path for deploying Ops Manager on Azure for use with <%= vars.product_short %>.</p>

<h3> Kubernetes Cluster Resources </h3>

Each Kubernetes cluster provisioned through <%= vars.product_short %> deploys the VMs listed below. If you deploy more
than one Kubernetes cluster, you must scale your allocated resources appropriately.

<table>
  <tr>
    <th>VM Name</th>
    <th>Number</th>
    <th>CPU Cores</th>
    <th>RAM</th>
    <th>Ephemeral Disk</th>
    <th>Persistent Disk</th>

  <tr>
    <td>master</td>
    <td>1</td>
    <td>2</td>
    <td>4 GB</td>
    <td>32 GB</td>
