YouTube
YouTube is the world’s largest online video-sharing and social media platform, owned by Google. Launched in 2005, YouTube allows users to upload, view, share, and comment on videos across a wide array of categories, including entertainment, education, news, and more. From an IT perspective, YouTube relies on complex technologies such as large-scale data storage, content delivery networks (CDNs), video encoding and transcoding, machine learning algorithms for recommendations, and robust security measures to handle billions of daily views and uploads. It serves as a prime example of scalable, cloud-based infrastructure supporting global content distribution.
