The main difference between an API and a load balancer is their function and purpose. An API’s (Application Programming Interface) primary function is to provide a unified interface to access backend services. On the other hand, a load balancer’s function is to distribute incoming network traffic across multiple servers.

An API Gateway acts as a central entry point for a group of microservices. It handles tasks like authentication, load balancing, and routing requests to the appropriate service.
