You have one huge file coming in over a constrained link. How do you distribute it to thousands of machines?

Focus on the methods and technologies you would use to efficiently distribute a large file across a vast number of machines while considering the constraints of the link. Discuss strategies like chunking the file into smaller pieces, implementing parallel downloads, and using protocols like BitTorrent or multicast if applicable. Address potential bottlenecks and how to mitigate them, such as load balancing and optimizing network usage. Finally, consider the trade-offs between speed, reliability, and resource consumption in your distribution plan.
