Demo | Three-tier web app in AWS with VPC, ALB, EC2 & RDS

In this video, I'm going to demonstrate how to set up basic networking and deploy a simple three-tier application in AWS Cloud.
This video is meant for beginners who want to start their hands-on journey on AWS Cloud. To keep the video simple, I have not included auto-scaling, caching in this use case, I'll cover the same in my upcoming videos.
Services used:
* VPC
* ALB
* EC2
* RDS

[@shamilshaikh3485]

Amazing explanation, I have one doubt, If we create three NAT gateways (one for each AZ), so should we put the entry all NAT or anyone NAT in the route table of private app and db route tables?

[@ajitinamdartech]

Hi Shamil,
If we create three NAT gateways in one AZ each, you will have to create separate route tables for that layer. You can’t have multiple NAT gateways in a single route table.

Hi Dhayalan,
Thanks for asking this question. I have deployed the application in only two availability zones as this is a demo. In real life scenarios you can deploy across all three AZs. Hope this answers your question.

Excellent Video.. I am a beginner to AWS and this video has helped to learn the architecture from basic. One query; in the Php MyAdmin login page, when did you created username and password? I means which username and password you entered? Please clarify.

Hi,
During the RDS creation I have passed the username and the password in here (24:16)

Thanks for the video! I have two questions there is any easy way to rename a subnet? Also when I try to copy the key pair to the jump server I get a message "chmod: cannot access ‘mykeypair.pem’: No such file or directory" The file is currently on the downloads folder.

[@ajitinamdartech]

Hi Debbie,
Thanks for your feedback. I think you are not in the right directory while trying to chmod. Also, if you want to rename the subnet, you can update the name tag if that helps.

Got the response from the comments..A very informative and comprehensive video.

Thanks Pooja, glad it was helpful for you!
I haven’t consumed the third AZ as it is a demo, for real life scenarios if your budget permits and you need that kind of resilience, you must always use all 3 AZs.
