##### SUMMARY

RDS services can auto-allocate storage. So you can start with the lowest ebs volume and don't care anymore about growing data in der database.  
The boto3 parameter to activate this feature is `MaxAllocatedStorage` (integer) 

>  The upper limit to which Amazon RDS can automatically scale the storage of the DB instance.
