Cloud Platform Migration to AWS for E-Learning System
SAID RAHHAL
Introduction
This document outlines the successful migration of an e-learning platform's infrastructure to AWS Cloud. The project aimed to modernize video content delivery, enhance scalability, and ensure seamless adaptive streaming by transitioning from the legacy Microsoft Azure Media Services, which faced retirement.
Project Overview
Background
The e-learning platform provided access to educational content through video streaming, leveraging Microsoft Azure Media Services. With the announcement of Azure Media Services’ retirement by June 2024, migration to AWS was identified as a strategic move to ensure uninterrupted service delivery and scalability.
Goal
The primary objectives were:
Migrate video storage and streaming services.
Implement scalable and automated workflows for future content uploads.
Enhance security, performance, and content delivery using AWS services.
Migration Strategy
The migration was executed in two phases:
Phase 1: Initial Migration
1. AWS Account Preparation
Provisioned AWS Virtual Private Cloud (VPC) for a segregated network environment.
Created Amazon S3 buckets for video storage.
Configured AWS MediaPackage for video segmentation and manifest generation.
2. Data Transfer and Setup
Established EC2 instances to act as migration servers.
Transferred video files from Azure Storage to AWS S3.
Organized files with naming conventions and folder structures.
3. Content Processing
Developed Lambda functions to generate SMIL files and integrate with MediaPackage.
Leveraged DynamoDB to map video manifests for playback tracking.
Configured CloudFront as a Content Delivery Network (CDN) to enhance streaming speeds.
4. API Gateway Integration
Built APIs using AWS API Gateway to serve video manifest files dynamically.
Phase 2: Automation and Future Handling
1. Workflow Automation
Created workflows using AWS Step Functions to automate video encoding and packaging.
Implemented AWS MediaConvert for multi-bitrate encoding.
2. Content Upload Process
Added a dedicated S3 bucket for new video uploads.
Automated encoding workflows triggered upon upload events.
3. Metadata Management
Integrated DynamoDB tables to track encoding statuses and manifest URLs.
Key AWS Services Utilized
Amazon S3: Primary storage for video files.
AWS MediaPackage: Video segmentation and manifest file creation.
AWS MediaConvert: Encoding video files to multiple formats.
AWS Lambda: Serverless processing for automated workflows.
DynamoDB: Metadata storage for manifest files.
CloudFront: Content caching and global delivery.
API Gateway: API management and integration with serverless applications.
Security Measures
Enforced IAM roles for granular access control.
Utilized signed URLs for secure access to content.
Implemented CloudFront authentication to restrict unauthorized access.
Outcomes
Seamless migration of legacy video content.
Automated workflows reduced manual intervention for content processing.
Enhanced scalability and performance using AWS native services.
Optimized delivery with low latency through CloudFront CDN.
Conclusion
This migration successfully transitioned the e-learning platform to AWS, modernizing its infrastructure and improving its ability to scale and deliver high-quality video content. The implemented workflows and architecture ensure the platform remains competitive and adaptable to future requirements.
