AWS Networking Basics For Programmers | Hands On

One of the biggest struggles programmers have, when they move into the Cloud, is networking. Concepts like VPCs, subnets, CIDR ranges, route tables, gateways, etc. are not naturally found in a programmer's toolkit. But the requirement is becoming more and more prevalent as the years pass.

In this video, I look to change that for you. I want to teach you the basics of networking using AWS. We'll not only build out an AWS architectural diagram and discuss terminology but we'll get our hands dirty by building out a common network in AWS ourselves.

This will be a practical tutorial and one that will ensure that you understand basic AWS networking.

Its easy to get a 200+ hour AWS course on Udemy, etc, but getting a 20 min vid that's straight to the point with a working example is gold. Thank you!

[zeeshawnali]

In 30 minutes I learned more than I have tried with hours of other lessons. Well done!

[Toolookanu]

Coming from passing my AWS SAA a couple of months ago and just a nice little refresh....you're incredible at teaching. Spot on with everything. Thank you so much for the refresh.

Coming from 18 years of network engineering experience and 5 years of cloud Architecting, I can tell you this video is incredibly informative and important for anyone involved in the technical side of the cloud

[imnottellingyoumyname]

Dude, this was the most helpful, to the point, digestable explanation of the basics in one place I have found. I've been trying to learn DevOps stuff and having all of these terms scattered around without any basic explanation has really stagnated my learning. I'll start learning one topic and find I've been googling and trying to understand the lingo for the entire day.

I feel like you've genuinely unlocked a huge chunk of my learning potential with this video. Thanks so much.

As a Network Engineer that has no experience with the Cloud, this was super informative! Thank you much!

[techjutsu]

10 min into the video and I just want to tell you how well you executed this demo. Thank you for your time and effort.

[emmanuelotobo]

I've been trying to understand these networking concepts in AWS for a few weeks now. Every resource I've found left me feeling like some things were still unclear - until I watched your video. It's honestly the best resource I've found and has really helped to solidify my understanding of these networking concepts. A heartfelt THANK YOU!

I'm sitting in an AWS office and watching this video

[robertboulter]

I am not a programmer but using this programmatic approach allowed me to see all the dependencies in a VPC build. Short and Concise and not overwhelming. Thank you very much.

[gdrnxog]

Travis, I find myself exactly where you were trying to understand networking and CIDR ranges. Thank you for all you do, your videos are easy to understand and apply.

[vuanhkhoa]

Tomorrow I will have an interview for a DevOps Internship position, and this video helps me review and solidfy my networking knowledge. Back then I was only learning theoretical things, and this practical guide make those theories become crystal clear !

[surpwer]

So glad you breakdown the terminology. The worst part of exploring the tech industry or a field within is the intensive level of vocabulary.

[rodrigobaptista]

I have been digging a lot on AWS cloud, the teaching style is definitely a game changer, and you sir, just changed the game. I have been through all those concepts, seeing it in practice just make much more sense. One of the best explanations, will follow up your content.
Thank you very much ☁️ 🚀

[simonb]

Thanks buddy ! I struggled to find a good video explaining route tables, and yours is just perfect !

[themindbadger]

I've struggled with the networking aspects (that everybody else seems to gloss-over and rush through) for ages, but this vid has just enough bite-size parts to de-mystify it for me. And the CIDR block description was bang on for what I needed to know. Many thanks!

[enpassant]

I am definitely interested in learning more about advanced Networking concepts. Your teaching style suits me perfect and gave me understanding. Kind of like Confucius said:
I hear and I forget.
I see and I remember.
I do and I understand!

[enpassant]

This is such a clear and succinct explanation of Networking. It makes the advanced Networking classes I've had make more sense.

[synen]

I recently discovered this channel Travis and I am already so thankful for all the genuine and invaluable knowledge you have provided.

[trido]

Your explanation regarding the CIDR range is pretty clear. I learned another trick for calculating the CIDR range. For example: The range of /24 is (32-24)^2 = 256 IPs. CIDR range of /16 is (32-16)^2 = 65, 536 IPs. I think AWS preserves the first 5 IP addresses. BTW, your tutorial on Terraform is also awesome. I was able to apply the knowledge right away.
