Exapark Amazon Server Discoverer

Exapark Amazon Server Discoverer runs on VMs in Amazon cloud, writes the Private IP addresses of all other VMs under the user's account to the Hosts file and automatically restores the link to the Elastic IP when you stop-and-start a virtual machine.

Issue and Resolution

Without Amazon Server Discoverer: For example, you have a database server and two application servers in an Amazon cloud, with the application servers addressing the database through a Private IP. If you stop and start the DB server, it will be assigned with a new Private IP. After this, you will need to reconfigure the application servers. If the DB server has an Elastic IP, the latter is unlinked when you stop the server and needs to be reassigned manually.

With Amazon Server Discoverer: In the above case, with Amazon Server Discoverer in place, all server addresses will be automatically registered in the Hosts file and the Elastic IP will be automatically restored. Now you can restart/stop and start your VMs in Amazon Web Services without having to worry about anything.
