How to Link Your Sub/Domain Name With Your AWS Instance Running Ubuntu — AWSSeries # Episode 03

In this post we will show you, from the very beginning, how to register a domain for your IoT project and redirect it to your Ubuntu instance, running in the cloud! this continues this previous post.

Hi, I’m from Brazil, and I register this domain here:

Fig 1. I register my domain for 3 years! This post follows a series. Init it here!

You have to search in your country which institution registers a domain officially.

Fine. Now come with me:

01#Step — As said, I just bought ownership for my domain(3 years);


02#Step — Go to your AWS Management Console and point it to this service:

Fig 2. Route53

03#Step — Click this button: Create hosted zone:

What is a Hosted Zone AWS?

A hosted zone is an Amazon Route 53 concept. A hosted zone is analogous to a traditional DNS zone file; it represents a collection of records that can be managed together, belonging to a single parent domain name. All resource record sets within a hosted zone must have the hosted zone’s domain name as a suffix. (from AWS FAQ)

04#Step — Config hosted zone like this:

Fig 4. Note that there is no www subdomain here. We leave it to record…Now Click this button:

05#Step — Now this screen opens showing us our DNS domain; Get each one of these address and transport it to your Registrar site (Registro.br):

Fig 5. AWS Route53 offers you DNS Servers Address (4 NSs)

06#Step — Now return to your Registrar site dashboard (https://registro.br/painel/) and save each of these addresses in your DNS (we will replace the local DNS with AWS DNS):

Fig 6. Click +DNS to add more DNS; Click Save Settings.

07#Step — From that point, we will have the propagation of the names of these servers pointing to your IP. It can usually last for hours … Wait for confirmation from your domain registrar.

08#Step — Now return to EC2, copy your IP Address:

09#Step —Now, open AWS Services>Route53:

Fig 8. Open Route53 Dashboard…
Fig 9. Select your hosted zone…
Fig 10. And Create a Record…
Fig 11. Note how I have set my parameters! Hit Create records button!

Now, when someone on the internet types www.j3.blog.br they will be redirected to this IP address.

We here could make a subdomain, like, iot.j3.blog.br, or mqtt.j3.blog.br, etc. It is up to you to choose one sub/domain that represents your project better!

Ready now, just wait for the propagation of the DNS name.

For the test, sometime later, just type:


And should appear on our test page from the previous lesson:

Fig 12. Type this /index.php or…
Fig 13. by browsing www.j3.blog.br/index.html see the Apache welcome page! saying that your remote Ubuntu instance is up and running!

For more info please watch this video or read this post: )

For now, That is it!

In the next AWS Episode, it’s for real: LetsEcrypt!

Bye o/

This process took from 14:00h of the day 04/01/2021 until .... not yet:/

Ready: 16:57h 04/01/2021 (roughly 3 hours later)
