 # Azure Kubernetes Service (AKS) Samples
 
-This repository contains a set of end-to-end samples that show how to deploy an [Azure Kubernetes Service (AKS)](https://learn.microsoft.com/en-us/azure/aks/what-is-aks) cluster and run a real workload on it, either against Azure in the cloud or locally on the [LocalStack for Azure](https://docs.localstack.cloud/azure/) emulator.
+This repository shows how to deploy an [Azure Kubernetes Service (AKS)](https://learn.microsoft.com/en-us/azure/aks/what-is-aks) cluster and run real workloads on it, either against Azure in the cloud or locally on the [LocalStack for Azure](https://docs.localstack.cloud/azure/) emulator. Everything here runs unchanged against both.
 
-Every sample deploys the same Vacation Planner web app, a small Python [Flask](https://flask.palletsprojects.com/) single-page application, and only differs in the Azure data service used to persist the activity data behind it: 
+It contains two kinds of content:
 
-- [Azure SQL Database](https://learn.microsoft.com/en-us/azure/azure-sql/database/sql-database-paas-overview?view=azuresql)
-- [Azure Database for MySQL flexible server](https://learn.microsoft.com/en-us/azure/mysql/flexible-server/overview)
-- [Azure Database for PostgreSQL flexible server](https://learn.microsoft.com/en-us/azure/postgresql/overview)
-- An in-cluster [PostgreSQL](https://www.postgresql.org/) database deployed as a Kubernetes [StatefulSet](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/)
-- [Azure Cosmos DB for MongoDB](https://learn.microsoft.com/en-us/azure/cosmos-db/mongodb/overview)
-- [Azure Cosmos DB for NoSQL](https://learn.microsoft.com/en-us/azure/cosmos-db/overview)
-- [Azure Blob Storage](https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction)
-- [Azure Files](https://learn.microsoft.com/en-us/azure/storage/files/storage-files-introduction), mounted into the pods over SMB or NFS by the [Azure Files CSI driver](https://learn.microsoft.com/en-us/azure/aks/azure-files-csi)

-This makes it easy to compare how the same application is wired up against different backing stores.

+- **[Samples](#samples)**: end-to-end deployments of the same web app, each persisting its data in a different Azure data service, so you can compare how one application is wired up against different backing stores.
+- **[Tutorials](#tutorials)**: standalone walkthroughs of individual AKS capabilities, from network policies and the cloud controller manager to KEDA autoscaling, the Gateway API, the Key Vault CSI driver, and Terraform and Bicep deployments.

-To run any sample you must first create the AKS cluster with one of the two scripts above. Then pick a sample from the [samples/](samples/) folder and run the numbered scripts in its `samples/<sample>/scripts` folder in order. The web app source code for each sample lives in `samples/<sample>/src`.
+Every sample deploys the same *Vacation Planner* web app, a small Python [Flask](https://flask.palletsprojects.com/) single-page application, and differs only in the Azure data service that persists the activity data behind it, listed in the table below. Keeping the application identical makes the comparison the point: what changes from one sample to the next is the data service, its provisioning, and how the app authenticates to it.
 
-All samples implement the same Vacation Planner web app. They only vary the underlying repository where the activity data is actually stored.
