What is External SSL Proxy Load Balancing?

It is primarily for SSL initiated traffic from the internet to GCP VMs.

  • It is a reverse proxy, layer 4 LB that distributes SSL traffic coming from the internet to VM instances on GCP.
  • Supports SSL offload where user SSL (TLS) connections are terminated at the load balancing layer, and then proxied to the closest available backend instances by using either SSL  or TCP.
  • supports global load balancing service with the Premium Tier
  • supports regional load balancing service with the Standard Tier
