The Media Service is a component designed to fulfill the following functions within the platform:
Content Upload and Management: It provides a platform for educators to upload and manage multimedia content, including PDF documents, MP4 videos, PowerPoint presentations (PPTX), and more.
MinIO Object Storage Integration: To ensure efficient storage and accessibility, the service utilizes the MinIO object storage system. Different types of media are stored in separate buckets within MinIO, allowing for structured storage.
GraphQL Endpoint: Users can interact with the service through a GraphQL endpoint, enabling the retrieval of URLs for uploading and downloading media files.
