This topic describes the prerequisites and resource requirements for installing Pivotal Container
Service (PKS) on Amazon Web Services (AWS).

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

Before you install PKS, you must install one of the following:

* Ops Manager v2.3.1 or later
* Ops Manager v2.4.x

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

To install an Ops Manager version that is compatible with the PKS 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 AWS, not the manual procedures. The Terraform procedures are the currently supported path for deploying Ops Manager on AWS for use with PKS.</p>

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

Installing Ops Manager and PKS requires the following virtual machines (VMs):

<table>
  <tr>
    <th>VM</th>
    <th>CPU</th>
    <th>RAM</th>
    <th>Storage</th>
  </tr>
  <tr>
    <td>Pivotal Container Service</td>
    <td>2</td>
    <td>8 GB</td>
    <td>16 GB</td>
  </tr>
  <tr>
    <td>Pivotal Ops Manager</td>
    <td>1</td>
    <td>8 GB</td>
    <td>160 GB</td>
  </tr>
  <tr>
    <td>BOSH Director</td>
    <td>2</td>
    <td>8 GB</td>
    <td>16 GB</td>
  </tr>
</table>

Each Kubernetes cluster provisioned through PKS 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>
  <tr>
    <td>master</td>
    <td>1</td>
    <td>2</td>
    <td>4 GB</td>
    <td>32 GB</td>
    <td>5 GB</td>
  </tr>
  <tr>
    <td>worker</td>
    <td>1</td>
    <td>2</td>
    <td>4 GB</td>
    <td>32 GB</td>
    <td>50 GB</td>
  </tr>
