Storage Optimization & Cost Efficiency
Optimizing storage in AWS is critical for cost efficiency, scalability, and performance. SecureCart, as a growing e-commerce platform, must ensure that its storage strategy aligns with business needs, balances cost, and maintains high availability. AWS offers various storage classes, lifecycle policies, and monitoring tools to optimize usage and reduce unnecessary spending.
✔ Why does SecureCart need storage optimization?
Minimizes costs by using the right storage class for different data types.
Prevents over-provisioning of high-cost, high-performance storage.
Ensures archived data is stored in cost-effective long-term storage.
Automates storage tiering to match changing workload demands.
🔹 Step 1: Choosing Cost-Optimized AWS Storage Solutions
✔ AWS provides various storage options optimized for different workloads and costs:
Storage Type
Best For
Cost Efficiency Considerations
SecureCart Use Case
Amazon S3 (Object Storage)
Unstructured data like images, logs, backups.
Use S3 Intelligent-Tiering for automatic cost optimization.
Stores product images, invoices, and logs.
Amazon EBS (Block Storage)
Persistent storage for EC2 instances.
Choose gp3 instead of gp2 for lower cost and better performance.
Hosts SecureCart’s database and app servers.
Amazon EFS (File Storage)
Shared storage across multiple EC2 instances.
Use EFS Lifecycle Management to move infrequent data to Infrequent Access (IA).
Stores configuration files for microservices.
Amazon FSx (Windows & Lustre)
High-performance file storage.
Optimize throughput capacity to reduce unused resources.
Processes AI-based recommendations efficiently.
✅ Best Practices: ✔ Use S3 for scalable, cost-effective storage with tiered pricing. ✔ Leverage EBS gp3 for cost savings on block storage. ✔ Enable EFS lifecycle policies to move inactive files to lower-cost tiers.
🔹 Step 2: Optimizing Amazon S3 for Cost Efficiency
✔ Why? – SecureCart stores large amounts of unstructured data (product images, transaction logs) and must minimize costs while maintaining availability.
✔ S3 Storage Classes for Cost Optimization:
S3 Storage Class
Purpose
Cost Efficiency Strategy
SecureCart Implementation
S3 Standard
Frequently accessed data.
Keep only essential high-traffic data in this tier.
Stores high-demand product images.
S3 Intelligent-Tiering
Automatically moves objects to cheaper tiers based on usage.
Enables automated cost savings.
Manages product catalog updates dynamically.
S3 Glacier
Archival storage with low retrieval frequency.
Use for long-term backups and compliance data.
Archives past order history for compliance.
S3 One Zone-IA
Cost-effective option for infrequent access, stored in a single AZ.
Use for temporary logs or backup copies.
Stores transactional logs with rare access.
✅ Best Practices: ✔ Enable S3 Lifecycle Policies to transition data automatically. ✔ Use Intelligent-Tiering for unpredictable access patterns. ✔ Compress and delete unnecessary files to optimize storage usage.
🔹 Step 3: Reducing Costs with Amazon EBS Volume Optimization
✔ Why? – SecureCart relies on Amazon EBS for its transactional database and application servers, requiring cost-efficient volume management.
✔ Amazon EBS Cost Optimization Techniques:
Optimization Method
Purpose
SecureCart Implementation
Use gp3 instead of gp2
Provides lower cost with customizable performance.
Reduces storage costs for SecureCart’s production servers.
EBS Snapshots
Backups of EBS volumes for disaster recovery.
Ensures cost-effective backup storage for critical databases.
Delete Unused EBS Volumes
Removes unattached volumes that still incur charges.
Automates cleanup of old instances to save costs.
✅ Best Practices: ✔ Resize volumes dynamically instead of over-provisioning. ✔ Use gp3 for better performance at lower costs. ✔ Schedule automated snapshots and delete obsolete backups.
🔹 Step 4: Saving Costs with Amazon EFS Optimization
✔ Why? – SecureCart uses Amazon EFS for shared application files, logs, and configuration data and must optimize storage costs.
✔ Amazon EFS Cost Optimization Techniques:
Optimization Method
Purpose
SecureCart Implementation
EFS Infrequent Access (IA) Mode
Moves rarely accessed files to lower-cost storage.
Optimizes costs for logs and infrequent assets.
Enable Automatic Lifecycle Management
Automates movement of files between Standard and IA tiers.
Reduces costs for old API logs stored in EFS.
Monitor EFS Utilization
Prevents overuse of expensive storage.
Ensures only necessary data remains in high-cost tiers.
✅ Best Practices: ✔ Enable EFS Lifecycle Management to reduce costs. ✔ Monitor EFS usage with CloudWatch to optimize capacity. ✔ Delete or archive infrequent data instead of keeping it online.
🔹 Step 5: Storage Cost Visibility & Optimization with AWS Monitoring Tools
✔ Why? – SecureCart uses AWS monitoring tools to analyze storage usage and optimize costs.
✔ AWS Monitoring & Cost Management Tools:
Tool
Purpose
SecureCart Use Case
AWS Cost Explorer
Analyzes storage costs over time.
Tracks S3, EBS, and EFS costs to identify savings.
AWS Trusted Advisor
Recommends cost-saving opportunities.
Flags unused EBS volumes and suggests lower-cost tiers.
Amazon CloudWatch
Monitors storage performance and usage.
Detects high-latency queries in RDS due to inefficient storage.
✅ Best Practices: ✔ Enable AWS Cost Explorer to track storage spending. ✔ Use Trusted Advisor to identify underutilized storage resources. ✔ Set up CloudWatch alarms for unexpected storage spikes.
🔹 Step 6: Implementing Data Lifecycle Management for Cost Efficiency
✔ Why? – SecureCart manages data retention policies to automatically transition data between storage classes, reducing long-term costs.
✔ Data Lifecycle Management Strategies:
Optimization Method
Purpose
SecureCart Implementation
S3 Lifecycle Policies
Moves infrequent data to lower-cost tiers.
Auto-archives order history in S3 Glacier.
EBS Snapshot Lifecycle Policies
Automates backup retention and deletion.
Retains only necessary database snapshots.
EFS Lifecycle Policies
Moves inactive data to Infrequent Access tier.
Optimizes application logs storage.
✅ Best Practices: ✔ Use lifecycle policies to automatically move aged data to lower-cost storage. ✔ Regularly audit and clean up old, unused data to save on storage costs. ✔ Implement automation tools (AWS Lambda, Step Functions) to enforce storage policies.
🚀 Summary
✔ Use S3 Intelligent-Tiering & lifecycle policies to optimize object storage costs. ✔ Deploy gp3 EBS volumes for better cost-to-performance ratio. ✔ Enable EFS IA mode to automatically reduce file storage expenses. ✔ Monitor and analyze storage spending using AWS Cost Explorer & Trusted Advisor. ✔ Implement automated lifecycle policies to transition aged data to cost-effective tiers.
