<div class="ulist">
<ul>
<li>
<p>A highly available architecture that spans two Availability Zones.*</p>
</li>
<li>
<p>A VPC configured with public and private subnets, according to AWS best practices, to provide you with your own virtual network on AWS.*</p>
<div class="ulist">
<ul>
<li>
<p>An internet gateway to allow internet access for bastion hosts.*</p>

<li>
<p>In the public subnets:</p>
<div class="ulist">
<ul>
<li>
<p>Managed network address translation (NAT) gateways to allow outbound internet access for resources in the private subnets.*</p>
</li>
<li>
<p>A Linux bastion host in an Auto Scaling group to allow inbound Secure Shell (SSH) access to Amazon EC2 instances in public and private subnets.*</p>
</li>
</ul>
</div>
</li>
<li>
<p>In the private subnets:</p>
<div class="ulist">
<ul>
<li>
<p>A ClickHouse client in an Auto Scaling group to allow administrators to connect to the ClickHouse cluster.</p>
</li>
<li>
<p>A ClickHouse database cluster that contains Amazon EC2 instances.</p>
</li>
<li>
<p>A ZooKeeper cluster that contains Amazon EC2 instances for storing metadata for ClickHouse replication. Each replica stores its state in ZooKeeper as the set of parts and its checksums. The default is three.</p>
