### **🔹 Step 1: Understanding AWS Storage Options & Cost Optimization Strategies**

✔ **AWS provides multiple storage options with different pricing models and use cases:**

| **AWS Storage Service**                           | **Purpose**                                                      | **Cost Optimization Strategy**                                                            | **SecureCart Implementation**                                               |
| ------------------------------------------------- | ---------------------------------------------------------------- | ----------------------------------------------------------------------------------------- | --------------------------------------------------------------------------- |
| **Amazon S3 (Object Storage)**                    | Stores structured and unstructured data at scale.                | Use **S3 Intelligent-Tiering** to automatically move infrequent data to lower-cost tiers. | **Stores SecureCart’s transaction logs, customer orders, and media files.** |
| **Amazon S3 Glacier (Archival Storage)**          | Provides low-cost, long-term archival storage.                   | Move old transaction logs and historical order data to **S3 Glacier Deep Archive**.       | **Stores SecureCart’s compliance and audit logs.**                          |
| **Amazon EBS (Block Storage for EC2)**            | Provides high-performance, persistent storage for EC2 instances. | Use **GP3 volumes** instead of **GP2** to reduce costs without performance impact.        | **Optimizes SecureCart’s EC2-based application workloads.**                 |
| **Amazon EFS (File Storage for Linux Workloads)** | Managed file storage for scalable workloads.                     | Use **EFS Infrequent Access (IA)** to optimize cost.                                      | **Supports SecureCart’s shared application files and logs.**                |
| **Amazon FSx (Managed File Systems)**             | Provides Windows and Lustre file system options.                 | Optimize cost by choosing **FSx for Windows Server with deduplication enabled**.          | **Stores SecureCart’s analytics and ML training datasets.**                 |

✅ **Best Practices:**\
✔ **Use S3 lifecycle policies to transition data to lower-cost storage tiers.**\
✔ **Enable intelligent-tiering for automatic cost optimization.**\
✔ **Use S3 Glacier for compliance and archival storage instead of keeping old data in S3 Standard.**\
✔ **Use EBS volume snapshots for backup instead of maintaining large, unused EBS volumes.**

✔ **How SecureCart optimizes storage costs across different workloads:**

| **Storage Type**                                        | **Purpose**                                                            | **Optimization Strategy**                               | **SecureCart Use Case**                                        |
| ------------------------------------------------------- | ---------------------------------------------------------------------- | ------------------------------------------------------- | -------------------------------------------------------------- |
| **Primary Storage (S3 Standard, EBS, EFS)**             | Stores frequently accessed order data, website content, and inventory. | Use **S3 Intelligent-Tiering** and **EBS GP3 volumes**. | **SecureCart’s main product catalog and transaction records.** |
| **Cold Storage (S3 Standard-IA, EFS-IA)**               | Stores logs, backups, and infrequently accessed reports.               | Move old reports to **S3 Infrequent Access (IA)**.      | **SecureCart’s monthly revenue reports.**                      |
| **Archival Storage (S3 Glacier, Glacier Deep Archive)** | Stores old compliance records and historical order history.            | Use **Glacier Deep Archive** for lowest-cost storage.   | **Long-term storage of SecureCart’s financial data.**          |

✅ **Best Practices:**\
✔ **Classify data by frequency of access and storage retention needs.**\
✔ **Use compression and deduplication techniques to reduce storage footprint.**\
✔ **Delete unnecessary or redundant data periodically to prevent unnecessary storage costs.**
