Exam CAS-004 topic 1 question 275 discussion

Provided answer is correct. Book definition below Content Delivery Network (CDN) is an example of implementing horizontal scalability. CDNs leverage the global footprint of cloud platforms by distributing and replicating the components of any service, such as web apps, media, and storage, across all the key service areas needing access to the content. This approach allows for the fastest delivery of content to local regions and provides unmatched scalability and performance. Typically, CDN Edge Servers are placed at the Internet Exchange Points (IXP) between different networks. The CDN Servers handle traffic originating in each network and communicate back to the Origin Server. CDN architecture improves website load times; improves availability and redundancy; reduces costs by limiting the amount of content delivered directly by an origin server; and improves website security by mitigating DDoS attacks, distributing digital certificates, and facilitating the use of specialized encryption hardware.

Simply addressing availability to international users.
