I own the example.com domain name. For the moment I connect that to two services.
One for firebase as a A name record for the sudomian business.example.com Another for AWS as A record and a CNAME record.
This is my namecheap Advanced DNS settings
| Type | Host | Value |
|---|---|---|
| A record | @ | AWS IP |
| CNAME record | api | example.com |
| A record | business | Firebase IP |
For the moment if I visit http://example.com/ it will show me the "Welcome to nginx", So that is clear that since the host is point to @ in the A record, the domian is fully connected to the AWS eC-2 What I want is to ONLY CONNECT api.example.com to AWS and connect full domain to vercel. So that I can use example.com and www.example.com in vercel.
How do I do this?

First, make sure that you have created an Elastic IP address in the Amazon EC2 management console. This is a static IP address that will stay with the instance (and can be moved to other instances).
Then, configure your DNS with an A-record that points api to the Elastic IP address:
| Type | Host | Value |
|---|---|---|
| A record | @ | Vercel IP address |
| A record | api | Elastic IP address (eg 1.2.3.4) |
| A record | business | Firebase IP |
