Akamai Technologies

Akamai Technologies operates a distributed edge network of over 325,000 servers across more than 1,000 cities, carrying roughly 15-30% of all web traffic. Founded in 1998 by MIT researchers working on distributed content delivery, the company began as a content delivery network (CDN) and now runs one of the largest authoritative DNS infrastructures in operation.

The CDN foundation has expanded well past caching. Akamai's Edge DNS platform handles billions of queries daily and is engineered for the scale modern applications demand, with built-in DDoS protection and traffic management that routes requests to the optimal server.

Layered on top of the network is the mapping system. Proprietary algorithms analyze network conditions, user locations, and content types continuously, then decide where each request should be served from. A click on a link resolves the domain name to the IP address of whichever edge server can deliver the content fastest.

Expansion into cybersecurity and cloud infrastructure has been systematic. The web application firewall and bot management products defend against attacks that can take websites offline, while microsegmentation technology from the $600 million Guardicore purchase in 2021 secures internal enterprise networks. The $900 million Linode acquisition in 2022 added compute and storage services that compete with AWS and Azure at the edge.

For the DNS and domain space, the relevant role is infrastructure. Akamai is the authoritative DNS provider for many of the domains it also delivers content for, handling the step that turns a domain name into a routable IP address. The $450 million acquisition of API security vendor Noname Security in 2024 extends that reach to the application layer where domains and APIs intersect.

CEO Tom Leighton describes the company as "the cybersecurity and cloud computing company that powers and protects business online." Revenue stands at $3.99 billion with over 10,000 employees, and the bet is that the edge infrastructure can serve cloud and AI the way it already serves content delivery and security.
