### **🔹 Step 2: SecureCart’s Hybrid Storage & Data Migration Strategy**

✔ **How SecureCart optimizes hybrid storage and migration costs:**

| **Use Case**                              | **Hybrid Storage Solution**      | **Cost Optimization Strategy**                                                                              |
| ----------------------------------------- | -------------------------------- | ----------------------------------------------------------------------------------------------------------- |
| **Migrating Product Images**              | **AWS DataSync → S3 Standard**   | **Uses DataSync to move high-resolution product images, then applies lifecycle policies for cost savings.** |
| **Storing Cold Data & Backups**           | **Storage Gateway → S3 Glacier** | **Stores infrequently accessed backups in Glacier Deep Archive to reduce costs.**                           |
| **Syncing Local File Shares**             | **Amazon FSx for Windows**       | **Extends SecureCart’s on-prem Windows file storage to AWS while reducing on-prem hardware costs.**         |
| **Securely Sharing Reports with Vendors** | **AWS Transfer Family (SFTP)**   | **Eliminates the need for expensive on-prem SFTP solutions by using AWS Transfer Family.**                  |

✅ **Best Practices:**\
✔ **Use lifecycle policies to automatically archive cold data to S3 Glacier.**\
✔ **Sync infrequently accessed shared files using Amazon FSx to avoid on-prem storage expansion.**\
✔ **Use Transfer Family for secure file exchange without on-prem FTP servers.**

### **🔹 Step 3: Cost Optimization for Data Migration**

✔ **Data migration can be expensive, but AWS provides cost-efficient strategies:**

| **Data Migration Method**    | **Cost Efficiency Strategy**                                          | **SecureCart Implementation**                                                           |
| ---------------------------- | --------------------------------------------------------------------- | --------------------------------------------------------------------------------------- |
| **AWS DataSync**             | Automates **incremental transfers** to reduce data transfer costs.    | **Syncs SecureCart’s order logs from on-prem to S3 only when changes occur.**           |
