A. Current Network Infrastructure:
a. Web Hosting:
- Hosting Provider: The website is hosted on a reliable cloud-based infrastructure, such as AWS, Google Cloud, or Azure. This ensures scalability and high availability.
- Server Specifications: Cloud instances are configured based on the anticipated load and traffic patterns, with options for auto-scaling to handle peak usage.
b. Content Delivery Network (CDN):
- Purpose: To optimize content delivery by caching static resources (images, CSS, JavaScript) and reducing latency.
- Provider: Services like Cloudflare or AWS CloudFront are used to speed up content delivery globally.
c. Domain and SSL:
- Domain: Managed through a reputable domain registrar.
- SSL Certificate: Enabled to secure data transmission and enhance user trust, especially for transactions and user account management.
d. Database Management:
- Database System: Likely uses a relational database system such as MySQL or PostgreSQL for managing course content, user data, and transactional records.
- Backup and Recovery: Regular backups and data recovery solutions are in place to protect against data loss.
e. Network Security:
- Firewall Protection: Implemented to safeguard against unauthorized access and cyber threats.
- DDoS Protection: Anti-DDoS measures to mitigate potential attacks that could disrupt service.
Network Design Considerations:
- Scalability: Cloud infrastructure supports auto-scaling to adjust resources based on traffic and usage demands.
- Redundancy: Redundant systems and failover mechanisms are designed to ensure high availability and minimize downtime.
- Load Balancing: Load balancers distribute incoming traffic across multiple servers to prevent overload on any single server and improve reliability.
