E-Commerce Platform - AWS

Problem Statement: E-Commerce Platform on AWS

Business Requirements:

1. Scalability: The platform should handle high traffic during peak shopping seasons without performance degradation.
2. High Availability: Ensure minimal downtime to provide a seamless shopping experience.
3. Data Security: Protect sensitive customer data and ensure compliance with regulations such as GDPR.
4. Cost Efficiency: Optimize resource usage to minimize costs while maintaining performance.
5. Disaster Recovery: Implement a robust disaster recovery plan to ensure business continuity.

Technical Requirements:

1. Web Application: Host the main e-commerce website that includes product listings, user accounts, and a shopping cart.
2. Database: Use a relational database to manage product inventory, customer information, and orders.
3. Search Functionality: Implement a fast and scalable search service for product queries.
4. Content Delivery: Use a CDN to deliver static content like images and videos quickly to users worldwide.
5. Monitoring and Logging: Implement monitoring and logging to track performance, errors, and user activity.

Solution Design:

1. Web Application:
   • Use Amazon EC2 instances or AWS Elastic Beanstalk to host the web application for easy scaling and management.
   • Deploy multiple instances across different AWS Regions and Availability Zones for high availability.
2. Database:
   • Use Amazon RDS for relational data storage with automated backups and multi-AZ deployment.
   • Implement Amazon DynamoDB for handling NoSQL data if needed for certain parts of the application.
3. Search Functionality:
   • Use Amazon OpenSearch Service (formerly Elasticsearch Service) for a robust, scalable search solution.
4. Content Delivery:
   • Use Amazon CloudFront to deliver static content globally, reducing latency and improving load times.
5. Storage:
   • Use Amazon S3 for storing large objects like images, videos, and backups.
6. Authentication and Security:
   • Use AWS Identity and Access Management (IAM) for identity and access management.
   • Implement AWS Key Management Service (KMS) to manage secrets and encryption keys.
7. Networking:
   • Use Amazon Route 53 for DNS routing and traffic management.
   • Set up Amazon VPC for secure communication between services.
   • Implement Security Groups and AWS WAF (Web Application Firewall) for enhanced security.
8. Monitoring and Logging:
   • Use Amazon CloudWatch for monitoring and logging application performance and security events.
   • Implement AWS X-Ray for detailed application telemetry.
9. Disaster Recovery:
   • Set up AWS Backup for regular backups of databases and other critical resources.
   • Implement cross-region replication and failover strategies for high availability.
