Proxy vs Reverse Proxy vs Load Balancer Explained (With Real-World Examples)

The podcast elucidates the distinctions and applications of forward proxies, reverse proxies, and load balancers in web architecture. Forward proxies enhance client-side privacy and content filtering, exemplified by TechCorp's implementation to manage employee internet access. Reverse proxies optimize server-side security and performance through SSL termination, caching, and infrastructure obfuscation. Load balancers ensure high availability and efficient traffic distribution across multiple servers, crucial for handling traffic spikes, as demonstrated by an e-commerce site during Black Friday. The technologies can be combined in multi-tier configurations to create comprehensive traffic management solutions. Selecting the appropriate solution depends on specific requirements, traffic volume, security needs, and scaling plans.
