+# Managed Storage
+
+Defang helps you provision the infrastructure you need to run your services. That infrastructure is designed to scale in and out without persistent storage, so you can build highly scalable services. But Defang can also help you provision managed services to store and persist your data, like [caches](#managed-redis), databases[<sup>\*</sup>](#managed-postgres) , and object storage[<sup>\*</sup>](#managed-object-storage).
+
+## Managed Redis
+
+Redis is an in-memory data structure store widely used for caching, real-time analytics, and session management due to its high performance, low latency, and support for various data types. Defang can help you provision a managed Redis instance. To read more about the specifics of how this works for each provider, see the following:
+  - [Playground](../providers/playground#managed-redis)
+  - [AWS](../providers/aws#managed-redis)
+
+### How to use Managed Redis
+
+To use managed Redis, in your `compose.yaml` file, use the `x-defang-redis` extension to define your Redis service. Adding the annotation will tell Defang to provision a managed instance, rather than running Redis as a service. Here's an example:
+
+```yaml
+  redisx:
+    image: redis:6.2
+    x-defang-redis: true
+    restart: unless-stopped
+    ports:
+      - mode: host
+        target: 6379
+```
+
+## Managed Postgres
+
+:::info
+As of July 22, 2024, managed Postgres is in development.
+:::
+
+Postgres, or PostgreSQL, is an advanced open-source relational database system known for its robustness, extensibility, and compliance with SQL standards, making it a popular choice for complex applications requiring reliable data integrity and sophisticated querying capabilities.
+
+## Managed Object Storage
+
+:::info
+As of July 22, 2024, managed object storage is planned for future development.

 ### Runtime
 
 The provider runs your workloads using ECS using Fargate. It provisions a VPC with public and private subnets, and deploys your services to the private subnets. It then provisions an Application Load Balancer (ALB) and routes traffic to your services.

+
+The Defang Playground is a free tier that allows you to experiment with Defang. The Playground is a shared that cannot be used to run production workloads. The Playground is a great way to get started with Defang and to experiment with the Defang CLI.
+
+This page highlights architectural considerations when deploying to the playground and any differences you might encounter when deploying to the playground versus deploying to your own cloud account.
+
+## Overview
+
+Overall, the Defang Playground is very similar to deploying to your own cloud account. The Playground runs on a Defang-managed AWS account, so you can expect it to work similarly to deploying to [AWS](./aws.md).
+
+## Managed Redis
+
+The playground supports [Managed Redis](../concepts/managed-storage.md#managed-redis). Fundamentally, this works the same as it does in [AWS](./aws.md#managed-redis).
