Hi, currently I have a Databridge installed onpremise in a Mac machine that is always on.

The syncronization between local DB and Zoho is configured to happen every 3 hours.

I'm going to migrate DB to AWS and use an EC2 instance as the databridge.

In order to save costs, I want to avoid having the EC2 turned on all the time.

I want to create an AMI image with an Ubuntu OS and databridge installed and ready to go. Then, spawn every 3h a new machine at the same time that the sync job would trigger. 

After this finnish, I'll terminate the EC2.

After 3 hours the cycle would repeat.

Is this possible?

PS: I can't directly connect Zoho to RDS because DB must be in private subnet
