IBM Cloud offers two content delivery networks: CDN and CIS. Which two networks underpin these two offerings?

IBM Cloud offers two content delivery networks (CDNs): CDN and Cloud Internet Services (CIS).

These two offerings are underpinned by the networks of Akamai and Cloudflare, respectively.

IBM Cloud CDN: IBM Cloud uses Akamai’s global network for its Content Delivery Network (CDN)

service. Akamai is one of the largest and most trusted CDN providers globally, known for its

expansive network that delivers content with low latency and high availability.

IBM Cloud Internet Services (CIS): This service is built on Cloudflare's global network and offers a

suite of services, including a CDN, DDoS protection, web application firewall (WAF), and more.

Cloudflare's network spans many data centers worldwide, optimizing traffic delivery and securing

applications.

Comparison with Other Options:

Limelight and KeyCDN (A), CDN 77 and CloudFront (C), Cloudflare and Fastly (D): These are other

CDN providers but do not represent the networks underpinning IBM Cloud's CDN offerings.
