+# Standardize Cluster Provisioning and Maintenance with Cluster Templates
+
+When you manage many Kubernetes clusters, configuring and upgrading them one by one does not scale. You need a way to
+apply the same configuration and upgrade rules across multiple clusters.
+
+In this tutorial, you will use **cluster templates** in Palette to create and manage clusters in a consistent way.
+Cluster templates let you reuse a cluster configuration, control when upgrades happen, and apply changes to multiple
+clusters at once.
+
+Cluster templates use two building blocks:
+
+- **Cluster profiles**, which define the software and infrastructure configuration of a cluster.
+- **Cluster template policies**, which control how clusters created from a template are operated, such as when upgrades
+  can run.
+
+A **maintenance policy** is one type of cluster template policy. Currently, maintenance policies are the only cluster
+template policy type available in Palette. When additional policy types are added, you will use the same workflow:
+create the policy, then link it to the cluster template.
+
+In this tutorial, you create two clusters named **dev** and **prod**. Both clusters are created from the same cluster
+template, but use different
+[cluster profile variables](../../../../../profiles/cluster-profiles/create-cluster-profiles/define-profile-variables/).
+This shows how you can reuse a single template while applying environment-specific settings per cluster.
+
+## What You Will Build
+
+In this tutorial, you will:
+
+- Create a cluster profile
+- Create a cluster template policy
+- Create a cluster template that uses the profile and policy
+- Deploy two clusters (**dev** and **prod**) from the same template
+- Set different profile variable values for each cluster
+- Update the template and upgrade both clusters together
+
+## Choose Your Workflow
+
+You can complete this tutorial using [Palette's UI on AWS](#provision-and-upgrade-clusters-using-the-palette-ui-for-aws)
+or [Terraform on AWS or Azure](#provision-and-upgrade-clusters-using-terraform) workflows. Choose the workflow that
+matches how you manage your infrastructure.
+
+:::warning
+
+This tutorial creates cloud resources. You will incur cloud costs until you complete the cleanup steps at the end of the
+tutorial.

+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+- A Palette account with permission to:
+  - Create cluster profiles
+  - Create cluster template policies
+  - Create cluster templates
+  - Create clusters
+  - Access the [Palette Community Registry](../../../registries-and-packs/registries/registries.md#default-registries)
+- A cloud account registered in Palette:
+  - [AWS](../../../clusters/public-cloud/aws/add-aws-accounts.md) for the Palette UI workflow
+  - [AWS](../../../clusters/public-cloud/aws/add-aws-accounts.md) or
+    [Azure](../../../clusters/public-cloud/azure/azure-cloud.md) for the Terraform workflow
+- Basic knowledge of [cluster profiles](../../../../../profiles/cluster-profiles/create-cluster-profiles/) and
+  [cluster profile variables](../../../../../profiles/cluster-profiles/create-cluster-profiles/define-profile-variables/)
+
+If you plan to use Terraform, you also need:
+
+- Terraform version 1.x installed
+- A [Palette API key](../../getting-started/palette/aws/setup.md#create-a-palette-api-key) set as an environment
+  variable
+
+```bash
+export SPECTROCLOUD_APIKEY=<your-api-key>
+```
