VIDEO TRANSCRIPT:
In this video I'll show you how to change the type or size of an existing EC2 instance.
In many cases, it is hard to predict the required instance type or size for a workload. But with AWS, you don't have to make a final decision up front. You can simply get started with an initial estimate and adapt as you go.

You can always change the size or type of an existing EC2 instance in three simple steps. All you have to do is:

1: stop the instance,
2: change the underlying type or size,
and 3: start the instance again.

Let me quickly walk you through this process in the AWS Management Console.

With the new instance type and size, we can now make sure the instance is selected again and click on "Instance state" → "Start instance". As you can see, the instance state is pending while the instance starts up, and a few seconds later is is up and running again.

Two things to note: The instance ID and the Private IP address haven't even changed. The only thing that's new is the public IP address, so please make sure to take this into account.

If you like this video, please make sure to give me a thumbs up. Thanks for watching, see you in the next one.
