Quiz on YouTube's Design
Test your understanding of the concepts related to the design of the YouTube via a quiz.
Assume that 100,000 users try to watch a football stream at 1080p in a densely populated city. If the CDN point of presence (PoP) in that area can provide a bandwidth of 300 Gbps for end users, which design best serves the clients without any buffering issues?
A)
Not the best choice because it will require an extraordinary bandwidth for the CDN to serve out 100,000 users each with 1080p quality of streaming service.
B)
This strategy will put huge burden on the backbone Internet. Bottlenecks will create issues.
C)
Cache servers maintained at the ISP will provide coverage to all the users reducing bandwidth requirements for the CDN as well as the origin servers.
D)
Streaming servers are an alternative to colocation sites. These will not be enough for 100,000 users within the same geographical location.
