"What is the difference between a CDN and a Web server? Since data delivery is made in closer proximity, a CDN essentially helps a website to speed up a website by reducing time needed to transport data across longer distances. Where web hosts serve all kinds of data, a CDN typically only hosts and serves static data"

CDN is good. But CDN has to be implement on top of a highly available web severs. Bad question and wording.

A _______________blank_______________________ leverages the global footprint of cloud platforms by distributing and replicating the components of a service to improve performance to all the key service areas needing access to the content. Content Delivery Network (CDN) is the answer. Key word "GLOBAL."

While implementing a content delivery network (CDN) is an important step for improving website performance and providing high-quality streaming media to users, it may not be the FIRST action that should be taken. This is because implementing a CDN is dependent on having a stable and reliable web server infrastructure in place.

Going with C due to the fact that the company has a global footprint. CDNs will help distribute content globally.

Example Scalable Designs 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. Caching improves the performance of services by creating copies of static, or infrequently changing content, separately from the complexities of the system as a whole. Caching in a cloud environment can be coupled with API Gateways so that the API gateway can direct requests to the cache to improve performance and reduce load on the main components of a service. Using a separate cache in this manner also allows for the cache to be independently scaled up to meet capacity demands.

Implementing a content delivery network (CDN) is also a reasonable first action to take as it can help improve website performance and user experience by delivering content to users from geographically distributed servers. This can help reduce the load on the origin server and provide quicker access to information as requested by users. However, the requirement to provide high-quality streaming media and create a user-friendly interface needs high-availability web servers to ensure that users can access the website whenever they want without any downtime. Hence, deploying high-availability web servers is often considered the more critical requirement and should be addressed first. That being said, both deploying high-availability web servers or implementing a CDN can be valid first actions, and it ultimately depends on the university's specific needs and priorities.
