Purpose of the Infrastructure

The goal of this infrastructure is to:

• Deliver public image assets quickly to users around the globe.
• Securely manage and serve video content requiring controlled access.
• Provide a scalable and reliable API for application functionality.

Components and Workflow

1. CloudFront (CF)

CloudFront serves as the entry point for all traffic and provides the following functionalities:

• Image Distribution: Serves public image assets stored in the S3 bucket.
• Video Distribution: Secures access to video content by requiring signed URLs.
• API Traffic Management: Routes API requests to the Application Load Balancer (ALB).

2. S3 Bucket - Images

• Purpose: Stores publicly accessible image assets, such as thumbnails, banners, or logos.
• Access: Content is publicly available and distributed via CloudFront for enhanced performance and caching.

3. S3 Bucket - Videos

• Purpose: Stores video content, including episodes or VOD.
• Access Control: Requires signed URLs to ensure only authorized users can access the content.
• Integration: Works seamlessly with CloudFront to deliver secured video streams to end users.

4. Application Load Balancer (ALB)

• Purpose: Balances incoming API traffic across multiple ECS tasks (containers).
• Features: Ensures high availability, scalability, and reliability of the API backend.

5. Elastic Container Service (ECS)

• Purpose: Hosts the backend API services using Docker containers.
• Scalability: Dynamically adjusts based on traffic and workload demands.
• Integration: ECS tasks are registered with the ALB, ensuring seamless load balancing.
