Currently we are running an application in a single amazon ec2 machine. On our application we are using some third party solution. For using those solution, we have asked the third party service provider to whitelist our ec2 machine ip.
our EC2 machine: IP - 220.127.116.11 Third party solution like global.bank.com and we have told global.bank.com to whitelist our IP
Now we want to scale up our application. We are planing to setup multiple node (our application in multiple ec2 machine) and a load balancer.
So my questions is, how i can manage our third party solution provider? Should I give all our ec2 machine ips to our third party solution providers for whitelist? Or is their any other solution to handle the situation?
