StackPath is a CDN provider head quartered in Dallas, Texas and has multiple offices across the U.S. StackPath was created after a large investment from ARBY Partners. Since then Stackpath has aqcuired Highwinds, and MaxCDN.
StackPath is highly focused on internet security as a CDN, and is positioned as a Security-as-a-Service providing many built-in options including a Web Application Firewall, DDoS mitigation, and many physical security measures at their data centers.
Not to be confused with Amazon Cloudfront, CloudFlare is a San Francisco-based CDN provider founded in 2009.
The company offers a Free plan, which includes a CloudFlare issued SSL certificate. The features included in the Free plan are basic; more become available to Pro, Business and Enterprise customers.
CloudFlare, together with Akamai, Fastly, Highwinds, Level3 and EdgeCast, is part of the Google Cloud Platform CDN Interconnect program. As part of the collaboration, 30 CloudFlare points-of-presence (PoPs) are directly connected to the Google Cloud infrastructure. When a content request comes in from a Google Cloud origin it will route directly through the interconnect between both parties rather than through the public Internet. As a result, latency is reduced for origin requests. Clients using Google Cloud also receive a discount to their egress traffic.
