+# Deploy EloqDoc with Eloq Operator
+
+This directory contains deployment guides for running EloqDoc on different cloud platforms using the Eloq Operator.
+
+## Overview
+
+The Eloq Operator simplifies the deployment and management of EloqDoc clusters by providing:
+- Declarative configuration through Kubernetes Custom Resources (CR)
+- Automated lifecycle management (deployment, scaling, updates)
+- Cloud-native integration with various cloud providers
+- Simplified storage configuration (local SSD, cloud object storage)
+
+## Deployment Guides by Cloud Provider
+
+| Cloud Provider  | Platform | Guide                                 |
+| --------------- | -------- | ------------------------------------- |
+| **AWS**         | EKS      | [Deploy on AWS EKS](./aws-eks.md)     |
+| **Baidu Cloud** | CCE      | [Deploy on Baidu CCE](./baidu-cce.md) |
+
+1. **Choose your cloud platform** from the guides above
+2. **Follow the platform-specific guide** for detailed step-by-step instructions
+3. **Deploy the Eloq Operator** and required components
+4. **Apply the EloqDoc CustomResource** to create your cluster
+5. **Connect and test** your EloqDoc deployment
+
+## Common Prerequisites
+
+Before deploying on any platform, ensure you have:
+
+- `kubectl` installed (v1.28 or later)
+- `helm` installed (v3.0 or later)
+- Access to a Kubernetes cluster (v1.28 or later)
+- Appropriate cloud provider CLI tools and credentials
+
+## Common Components
+
+All deployments require the following components:
+
+1. **cert-manager** (v1.19.0+)
+   - Manages TLS certificates for webhook endpoints
+   - Required by the Eloq Operator
+
+2. **OpenEBS** (v4.3.0+)
+   - Provides local persistent volume provisioning
+   - Supports XFS filesystem with quota
+
+3. **Eloq Operator**
+   - Manages EloqDoc cluster lifecycle
+   - Deploys and configures EloqDoc instances
+   - Handles storage and networking configuration
+
+## Deployment Architecture
+
+EloqDoc uses a hybrid storage approach:
+
+- **Block Storage (Raft Log)**
+  - Cloud block storage (EBS/CDS) for raft consensus logs
+  - Used by the log service for distributed consensus
+  - Persistent volumes for durability and consistency
+  - Provisioned via CSI drivers (EBS CSI/CDS CSI)
+
+- **Local Storage (Hot Data)**
+  - Fast local SSDs for cache and active data
+  - XFS filesystem with quota support
+  - Provisioned via OpenEBS local PV
+
+- **Object Storage (Cold Data)**
+  - Cloud object storage (S3/BOS) for persistent data
+  - Transaction logs and SST files
+  - Automatic bucket creation and lifecycle management
