Latency Reduction and Data Utilization Optimization for Online Classes

Client: Leading Ed Tech Company

Problem Statement: The client, a leading ed-tech company conducting online classes, faced challenges related to latency in video streaming and data utilization optimization. They required a solution that would reduce latency, improve video streaming performance, and optimize data usage.

Spanidea Solution: Spanidea provided a comprehensive solution to address the client’s requirements. The key components of the solution included:

Chunked Video Streaming:

The video stream was broken into smaller chunks to optimize data utilization and reduce latency. These video chunks were then directly stored in an AWS S3 bucket.

Stream Access through S3 Bucket:

Instead of using an RTMP (Real-Time Messaging Protocol) server for video streaming, users accessed the video stream directly through the S3 bucket. This reduced the load on the RTMP server and improved overall system performance.

AWS CloudFront and S3 Architecture:

To cater to users spread across the globe, an architecture was proposed with AWS CloudFront and S3. AWS CloudFront, a content delivery network (CDN), was used to distribute the video stream globally, while S3 served as the storage for the video chunks. This architecture ensured efficient content delivery and reduced latency for users in different regions.

Performance Testing:

A dedicated testing server was set up to simulate real-world usage. During the testing, 15,000 users were live for 15 minutes, streaming videos at both 720p and 480p resolutions. This allowed for performance evaluation and fine-tuning of the system.

Business Benefits: The implementation of Spanidea’s solution brought several benefits to the client:

Latency Reduction:

The chunked video streaming approach and direct access to the video stream through the S3 bucket resulted in a significant reduction in latency. The latency was reduced from 40-45 seconds to 15 seconds for users joining the live stream and 25 seconds for users joining after the live stream had started. This improvement in latency enhanced the real-time interaction and engagement for online classes.

Seamless Video Streaming:

By leveraging AWS CloudFront and S3, the client achieved seamless video streaming for users worldwide. The content delivery architecture ensured optimized data transfer, reduced buffering, and improved video quality, resulting in a smooth and uninterrupted streaming experience.

Improved User Experience:

The reduced latency, seamless video streaming, and optimized data utilization greatly improved the overall user experience. Students and instructors could interact in real-time, ask questions, and participate actively in online classes without significant delays or disruptions.

Key Technologies: The key technologies used in the solution included:

AWS CloudFront: AWS CloudFront, a scalable and secure CDN service provided by Amazon Web Services, was utilized for global content delivery and reduced latency.
RTMP Server: The load on the RTMP server was minimized by allowing users to directly access the video stream through the S3 bucket, resulting in improved system performance.
AWS S3: AWS S3 served as the storage for the chunked video stream, enabling efficient data utilization and easy access for users.

This case study highlights Spanidea’s successful implementation of a solution to reduce latency and optimize data utilization for online classes. By leveraging chunked video streaming, direct access through an S3 bucket, and utilizing AWS CloudFront and S3, the client achieved reduced latency, seamless video streaming, and improved user experience for online learning.
