Key Insights

What is a Reverse Proxy?

• A reverse proxy acts as a server-side intermediary that receives client requests and communicates with backend services.
• It ensures that only authorized users can access specific services, addressing security in modern cloud environments.

How Reverse Proxies Work

• Every inbound request is validated for identity and Permission before reaching the application, enhancing security.
• The process involves protocols and configurations that dictate how clients connect to the services through the proxy.

Comparison with VPN

• Unlike a VPN, which creates a secure tunnel for traffic, reverse proxies focus on validating user identities and enforcing access controls.
• Reverse proxies can provide additional layers of security and perform load balancing for backend services.

Identity-Aware Reverse Proxy Architecture

• The article illustrates an architecture involving Envoy as the proxy with Keycloak for identity management.
• This setup ensures that all service requests are authenticated and authorized based on user roles and policies.
