IP that resolves to other IP

Question

Hello,
I hope you can help me or point me in the right direction.

We have several IoT devices on the field which comunicate via LTE to a given server IP, changing the server IP on the devices comes with the risk of losing remote access to the IoT devices, so we rather keep this IP fixed, but at the same time we want to have the ability to change which server gets this communication. This looks like a Domain DNS, but the IoT devices only accept IPs.

So... I need to get a fixed IP address  that resolves to another IP address (EC2 instance) which I can change on the fly.

Thanks guys

Answer

It sounds like you want an **E**lastic **IP** Address.
This is a fixed IPv4 address that you can reassign from one EC2 instance to another. This address stays persistent through instance stops and starts.

Answer

Depending on your use case and how many region you IOT devices are connecting from AWS Global Accelerator Might also be able to reduce you latency
