Initial Requirements (100,000 users/hour):

• Concurrent streams: ~28,000 (assuming 10-minute average watch time)
• Storage needed:
  • Daily Active users (DAU): 2,400,000 (100k/hr)
  • Average video uploaded per user per day: 0.005 videos (0.5 % of DAUs upload a video daily)
  • Average video size: 100 MB (at 1080p resolution, H264 compression)
  • Daily uploads: 2,400,000 x 0.005 = 12,000 videos/day
  • Daily storage for uploads: 12,000 x 100 MB = 1.2 TB/day
  • Annual video uploads: 1.2 TB/day x 365 days = 438 TB/year
