Does this answer your question? (from the blog)

How do load balancers differ from reverse proxies? While both components distribute requests, load balancers primarily focus on improving performance, availability, and fault tolerance by distributing traffic among multiple backend servers. Reverse proxies, on the other hand, operate at the application layer and offer additional functionality such as URL rewriting, content compression, and access control. So, when should you choose a load balancer or a reverse proxy? It depends on your specific requirements and whether you need advanced application-level features.
