Transforming eLearning with AWS Storage & Compute Solutions

The client, a prominent NBFC in India, was scaling its internal eLearning system for training and certifying employees. This platform, accessible via mobile and web apps, was generating and storing large volumes of data including:

·       Learning content (documents)

·       Financial transaction receipts

·       Exam question papers and certificates

·       Billing invoices and user-uploaded images

The company also required comprehensive, secure logging for auditing and compliance, but lacked a cost-effective, scalable, and secure storage structure.

Saints & Masters designed a scalable, secure, and cost-efficient cloud architecture on AWS to manage the client's growing eLearning platform and logging requirements.

·       Centralized Storage with Amazon S3

o   All application data such as learning materials, receipts, certificates, and images were stored on Amazon S3. Frequently accessed data used by S3 Standard, while older or less-used data was moved to S3 Standard-IA to reduce storage costs.

·       Automated Backup & Archiving

o   Backup strategies were implemented using S3 lifecycle policies to automatically transition and archive data, ensuring durability and easy recovery when needed.

·       Application Hosting & Database

o   The platform was hosted on Amazon EC2, with Amazon RDS managing structured data. An Application Load Balancer ensures high availability and smooth traffic distribution.

·       Centralized Logging & Monitoring

o   Logs from multiple services were collected using Amazon CloudTrail and VPC Flow Logs and stored securely in S3 for auditing and compliance.

·       Security Enhancements

o   AWS WAF was deployed to protect applications from common web threats, ensuring secure access to the platform.

·       Cost Optimization with Automation

o   Amazon Event Bridge and AWS Lambda were used to automatically stop non-essential EC2 instances during off-hours, significantly reducing operational costs.

The implemented AWS-based solution delivered significant improvements in performance, cost efficiency, and operational management for the client's eLearning platform:

·       High Data Durability & Availability: Achieved high data durability with Amazon S3, ensuring reliable and long-term data storage.

·       Reduced Infrastructure Costs: Optimized resource usage led to a 20% reduction in EC2 costs through automated instance scheduling during non-business hours.

·       Improved Security & Compliance: Centralized logging across AWS services enabled better audit readiness, traceability, and regulatory compliance.

·       Efficient Storage Management: Lifecycle policies helped automatically move data to cost-effective storage tiers, reducing overall storage expenses.

·       Simplified Operations: Automated backups, archiving, and monitoring reduced manual effort and improved overall system reliability and manageability.
