+
+In {product-title} version {product-version}, you can install a cluster on Amazon Web Services (AWS) into an existing VPC, extending workers to the edge of the Cloud Infrastructure using AWS Local Zones.
+
+AWS Local Zones are a type of infrastructure that place Cloud Resources close to the metropolitan regions. For more information, see the link:https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-local-zones[AWS Local Zones Documentation].
+
+{product-title} can be installed in existing VPCs with Local Zone subnets. The Local Zone subnets can be used to extend the regular workers' nodes to the edge networks. The edge worker nodes are dedicated to running user workloads.
+
+One way to create the VPC and subnets is to use the provided CloudFormation templates. You can modify the templates to customize your infrastructure or use the information that they contain to create AWS objects according to your company's policies.
+
+[IMPORTANT]
+====
+The steps for performing an installer-provisioned infrastructure installation are provided as an example only. Installing a cluster with VPC you provide requires knowledge of the cloud provider and the installation process of {product-title}. The CloudFormation templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.
+====
+
+== Prerequisites
+
+* You reviewed details about the xref:../../architecture/architecture-installation.adoc#architecture-installation[{product-title} installation and update] processes.
+* You read the documentation on xref:../../installing/installing-preparing.adoc#installing-preparing[selecting a cluster installation method and preparing it for users].
+* You xref:../../installing/installing_aws/installing-aws-account.adoc#installing-aws-account[configured an AWS account] to host the cluster.
++
+[IMPORTANT]
+====
+If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see link:https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html[Managing Access Keys for IAM Users] in the AWS documentation. You can supply the keys when you run the installation program.
+====
+* You noted the region and supported link:https://aws.amazon.com/about-aws/global-infrastructure/localzones/locations[AWS Local Zones locations] to create the network resources in.
+* You read the link:https://aws.amazon.com/about-aws/global-infrastructure/localzones/features/[Features] for each AWS Local Zones location.
+* You downloaded the AWS CLI and installed it on your computer. See link:https://docs.aws.amazon.com/cli/latest/userguide/install-bundle.html[Install the AWS CLI Using the Bundled Installer (Linux, macOS, or UNIX)] in the AWS documentation.
+* If you use a firewall, you xref:../../installing/install_config/configuring-firewall.adoc#configuring-firewall[configured it to allow the sites] that your cluster requires access to.
++
+[NOTE]
+====
+Be sure to also review this site list if you are configuring a proxy.
+====
+* If the cloud identity and access management (IAM) APIs are not accessible in your environment, or if you do not want to store an administrator-level credential secret in the `kube-system` namespace, you can xref:../../installing/installing_aws/manually-creating-iam.adoc#manually-creating-iam-aws[manually create and maintain IAM credentials].

+= Opting into AWS Local Zones
+
+If you plan to create the subnets in AWS Local Zones, you must opt in to each zone group separately.
+
+.Prerequisites
+
+* You have installed the AWS CLI.
+* You have determined into which region you will deploy your {product-title} cluster.
+
+.Procedure
+
+. Export a variable to contain the name of the region in which you plan to deploy your {product-title} cluster by running the following command:
++
+[source,terminal]
+----
+$ export CLUSTER_REGION="<region_name>" <1>
+----
+<1> For `<region_name>`, specify a valid AWS region name, such as `us-east-1`.
+
+. Review the list of zones that your region contains by running the following command:
++
+[source,terminal]
+----
+$ aws ec2 describe-availability-zones \
+    --filters Name=region-name,Values=${CLUSTER_REGION} \
+    --query 'AvailabilityZones[].ZoneName' \
+    --all-availability-zones
+----
++
+Depending on the region, the list of available zones can be long. The different zones use the following naming conventions:
++
+`${REGION}[a-z]`:: Availability zones available in the region.
+`${REGION}-LID-N[a-z]`:: Available AWS Local Zones. `${REGION}LID-N` is the zone group identifier, and `[a-z]` is the zone identifier.
+`${REGION}-wl1-LID-wlz-[1-9]`:: Available Wavelength zones.
+
+. Export a variable to contain the name of the Local Zone to host your VPC by running the following command:
++
+[source,terminal]
+----
+$ export ZONE_GROUP_NAME="${CLUSTER_REGION}-<location_identifier>-<zone_identifier>" <1>
+----
+<1> For `<location_identifier>-<zone_identifier>`, specify the location identifier and zone identifier for the Local Zone that you selected for your region. For example, specify `nyc-1a` to use the US East (New York) Local Zone.
+
+. Opt in to the zone group on your AWS account by running the following command:
++
+[source,terminal]
+----
+$ aws ec2 modify-availability-zone-group \
+    --group-name "${ZONE_GROUP_NAME}" \
+    --opt-in-status opted-in
+----
