Akamai Technologies, Inc. is a global content delivery network (CDN), cybersecurity, and cloud service company, providing web and Internet security services. Akamai's Intelligent Edge Platform is one of the world's largest distributed computing platforms. The company operates a network of servers around the world and rents out capacity on these servers to customers who want their websites to work faster by distributing content from locations near the user. When a user navigates to the URL of an Akamai customer, their browser is directed by Akamai's domain name system to a proximal edge server that can serve the requested content. Akamai's mapping system assigns each user to a proximal edge server using sophisticated algorithms such as stable matching and consistent hashing, enabling more reliable and faster web downloads. Further, Akamai implements DDoS mitigation and other security services in its edge server platform.
An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from. The application firewall can control communications up to the application layer of the OSI model, which is the highest operating layer, and where it gets its name. The two primary categories of application firewalls are network-based and host-based.
