AWS re:Invent 2021 - Integrate Amazon EKS with your networking pattern

Because of its security, reliability, and scalability capabilities, Amazon EKS is used by organizations in their most sensitive and mission-critical applications. This session focuses on how you can set up networking for Amazon EKS, connect it to Amazon VPC, and expose your Kubernetes application using Elastic Load Balancing and AWS App Mesh.

One of the best videos out there on Amazon EKS networking !!

Kudos to both architects

Echoing others' comments below; great work (as usual) Tom and Theo! During t=19:10 to 21:10, the key difference in the 2 scenarios is the location of the Worker node -- Public Subnet as in the first case (Source NAT enabled, _EXTERNALSNAT=false) where the NAT Gateway is bypassed and goes directly to IGW because it already has route to Internet (it's in the Public subnet with such a route), and Private Subnet as in the 2nd case (Source NAT disabled, _EXTERNALSNAT=true) where the NAT Gateway performs the necessary translation (or NAT64 if it's an IPv6 address) before advertising to IGW and onward to the Internet. Tom did explain this, but the slide transition was fast so I missed this initially; this nuance helped me understand the two use-cases; it may help others too.
