Previous Question Next Question

Load balancers handle SSL termination by decrypting incoming SSL/TLS traffic at the load balancer level, allowing it to inspect and manage the traffic before forwarding it to backend servers over plain HTTP. This offloads the SSL processing from the backend servers, improving their performance and simplifying certificate management.

Example Concept: SSL termination occurs when a load balancer decrypts incoming SSL/TLS traffic, allowing it to manage and distribute the traffic to backend servers over non-encrypted connections. This process involves the load balancer handling SSL certificates and keys, performing the decryption, and then forwarding the traffic to the appropriate server. This setup reduces the computational load on backend servers and centralizes SSL certificate management, making it easier to update and maintain.

Additional Comment:

SSL termination can improve performance by offloading cryptographic processing from backend servers.
Centralized certificate management simplifies updates and renewals.
Ensure the load balancer is configured securely to prevent unauthorized access to decrypted data.
Consider using SSL re-encryption if security policies require end-to-end encryption.
