**Layer 7**
What is Layer 7?
Layer 7 refers to the application layer of the OSI model. It is the layer closest to the end user, providing the interface between applications and the network. Technologies operating at Layer 7, such as HTTP, SMTP, and DNS, deal with the actual content of messages and requests, enabling functionalities like web browsing, email, and domain name resolution. Common uses include load balancing (application-aware routing), web application firewalls (inspecting HTTP traffic), and content delivery networks (caching and serving content).
