I need to extend the capabilities of an EC2 instance on AWS. The thing is, I have a t3a.small instance, and I wanted to "upload" it to t3a.medium. I've been reading the documentation, but I can't confirm if the instance will continue to work after I've stopped it, expanded it, and started it again. Apparently it is necessary that the volume is EBS, the elastic ip... etc. The operating system installed is a Centos 7.
Basically I need to know if it is possible to resize the features of the machine and then make it work as before. If anyone has experience or has had to perform these extensions. Any information needed, let me know. Thank you for your attention.
Once the instance is stopped (note, stop is not terminated , if you terminate an instance there is no going back) you can change the type of the instance to a different one according to your needs.
To change the type you select the image in the AWS console, right click and in the Instance settings menu choose " Change Instance Type " and there it lets you choose the type of micro that is going to be used from that moment on.
You can repeat this operation as many times as you want. The only requirement, as I have mentioned, is that the instance must be stopped.
