What is Elastic IP address?

Elastic IP address is a permanent IP address that can be assigned to your instance for as long as you want to keep it.

If you do not assign Elastic IP address to your instance, then every time you stop and later re-launch your instance it will have a new IP, different from the one it had before you stopped it.

If you’ve set up some complex settings that are tied to the IP of your instance (like CloudFront), then you’ll have to re-set everything every time. Doing the same work over and over does not sound great, and here Elastic IP address comes like useful tool.

Before we begin

For this tutorial to be useful to you, ideally should already have an account on Amazon Web Services and an instance in your EC2 console.

If by chance you came here before you managed to get all that, please check out this tutorial first :
How to create SRT server and start streaming over the SRT Protocol.

There we cover the process of launching an instance on AWS in great detail.

Make sure to learn how to stop or terminate your instance when your work is done, as AWS charges running instances on a per-hour basis.

⚠️ Be aware of the cost

AWS charges a small per-hour fee for the IPs that are allocated in your account.

As small as $0.005 per hour. Which is around $3.6 per month.

However, different regions have different prices.
