AWS Networking -a look behind the scene -where can I have a look ? :-)

Hi guys

Are there any documents that show what is the network piece behind any network concept used in AWS?I would like to understand how route tables are implemented. ACLs are ...clear and not quite (they have limitations compared with the ACLs we know from a regular NOS). How are the network segments stitched together, how are the network load balancers, vpn gateways firewalls built and so on

Also I am curious about the way they build their backbone, how DirectConnect is built and so onSomething like in this doc https://www.slideshare.net/AmazonWebServices/behind-the-scenes-exploring-the-aws-global-network-net305-aws-reinvent-2018
