Amazon Virtual Private Cloud (VPC) Routing Deep Dive

Routing can be a complex topic and it's no different in an Amazon VPC. In this video, I'll simplify the subject and give you the core knowledge you need to understand how routing behaves in AWS within a VPC.

This AWS video tutorial covers VPC routing, route tables, prefixes, NAT gateways, VPC peering, gateway route tables, internet gateways and more.

This video is from our AWS Certified Solutions Architect Professional course in which I dive deep into subjects like this and teach you how to build architectures on AWS hands-on.

This is an excellent and pragmatic overview without feeling too granular. Great job!

You’re the best instructor on the WEB thank you!!!

Well explained, Neal! The term "longest prefix" is used throughout AWS docs and presentations, but didn't realize until your video what a simple concept this is -- that "length" of prefix merely means more specific IP, which necessarily makes it "longer". Also, your use of route table on IGW explains how to force traffic through appliance. Thank you.

Excellent explanation. Keep up the good work.

Your videos are excellent, Neal.

I, especially, appreciate your use of graphics. It beats the hell out of my reading the content over and over. Because when I take practice exams, it seems I get the same VPC questions incorrect when I have to select multiple options on a particular question.

BTW, I clearly understand using /32 to target a specific IP address.

Very precise and good explanation to gain good confidence on real life scenario's questions.

[marcogonzalez]

Detailed video with specific scenarios. Thank you!

[mattongbp]

Thanks very much. Very concise information presentation.

Great video. I just have one question - how would you communicate between public and private subnets? Would this be via private gateway?

This video may be uploaded in 1080p but your jawline is in 4k. God damn I'm jealous.

What is the purpose of "Edge associations" on Route Tables? Is this what you're talking about in the last example with the Security Appliance? I am having a hard time finding any information or examples for these.

Suppose we want to connect two private subnets in two different VPC'c with peering connection. How will we create a Route table . Can we use the Main route table of both VPC to define the routes. Or we need to create a private route table in the second VPC

Hi, could anyone explian what is"Gateway Route table"? I have checked everywhere on AWS control panel but I did not find it. Also I don't how to attach route table to a IGW or VGW? Many thanks.

[Sky-nthy]

The main route table of the vpc does not have target igw in my setting. why is this?

[PraneetCastelino]

Would we use this architecture in the real world as in two VPC's with the same CIDR block address?
