Description: Path-based routing is a technique used in Elastic Load Balancers (ELB) that directs network traffic based on the URL path of the request. This strategy is particularly useful in environments where multiple services or applications are managed within the same infrastructure. By analyzing the URL path, the router can decide which specific server or service to send the request to, thereby optimizing load distribution and improving system efficiency. This technique not only helps balance the load among different server instances but also allows for the implementation of more complex routing policies, such as separating traffic between versions of an application or managing different types of content. Additionally, path-based routing facilitates scalability, as it allows for the addition or removal of services without impacting user experience. In summary, this technique is essential for ensuring optimal performance and high availability in modern applications that require efficient web traffic management.
