Scalability and Performance:

In Tutorac Academy, the primary USP lies in the quality of its content. However, the substantial size of each video (average exceeding 2 GB for a 20-minute video) posed challenges in performance and scalability. The target audience, primarily from lower-tier cities, often faces issues related to internet speed and availability.

To address these challenges, we implemented a solution focused on video chunk loading and dynamic video rendition selection based on available internet speeds. During video uploads, we leveraged AWS Media Pipeline for transcoding videos into multiple renditions. These renditions were then served through CloudFront to ensure appropriate output based on users' internet speeds. This approach optimized performance and scalability while catering to the diverse needs of our user base.

Security and Privacy Concerns:

In Tutorac, the creation of premium, in-house video content of exceptional quality raised significant concerns regarding security and privacy. It was imperative to prevent external intruders from downloading and exposing these videos in the market.

Initially, we addressed this challenge by integrating external DRM solutions. However, as time progressed, this approach proved costly and unsustainable for the client. Consequently, we devised an innovative security approach.

During video transcoding, we generated a hash for each video chunk and bound it to a unique signed URL using advanced hash algorithms. These URLs were then served through CloudFront. By implementing this method, we ensured that intruders were unable to access the videos, thereby safeguarding the integrity and exclusivity of the premium content.
