[ChristianCastil]

this document describes how to use a MIG and iLB to distribute the traffic on all members for East-West and Egress.

also there is a video explaining all the steps

Excellent Work Christian. Love the detailed explanation and the fact that we can leverage a very simple script to address the health probe replies to ILB.  I would also be nice to point to GCP relevant articles on ILB next hop, alias & health probes in the doc as reference.

As usual great job Christian!! I was not aware of the limitations of client affinity for the ILB in GCP, thanks for sharing!

Hi Christian,

Great tutorial. I've also learned that the TCP ILB can be used also for UDP traffic by putting the port to 'all'.
