+# Ghaymah Block Storage for Stateful Workloads
+
+## Overview
+
+Stateful applications store persistent data that must remain available even if a container is restarted, replaced, or moved to another node.
+
+Ghaymah Block Storage provides persistent storage that can be attached to stateful workloads such as databases.
+
+---
+
+## Common Stateful Workloads
+
+- MySQL
+- PostgreSQL
+- MongoDB
+- Redis (Persistent Mode)
+
+---
+
+## How It Works
+
+1. The database container stores its data on a Ghaymah Block Storage volume.
+2. If the container fails, a new container can be started.
+3. The same Block Storage volume is reattached.
+4. The application continues using the existing data.
+
+---
+
+## Benefits
+
+- Persistent data storage
+- High durability
+- Faster recovery after failures
+- Data remains available after container restarts
+- Suitable for production database workloads
