How do I Start/Stop AWS RDS Instances using Boto?
You can only start or stop AWS RDS instance of single availability zone instances. For your case, you will have to check if the multi-AZ option is enabled or disabled. 
Incase your database is in Multiple availability zone, the best way would be to take the snapshot and restore it.
I had a question about Amazon RDS. I wanted to Start/Stop AWS RDS Instances at my need . AWS Console does not allow me to do so.  
The Only method I know is to take a snapshot of the rds instance and delete it and when I need it then a create rds instance using that snapshot.
Is there any better way to acheive the same using Boto?
