Limits of Opsworks

Hey all, I 'm a newbie in opsworks. I just wanted to know if there are any limits to AWS OpsWorks?

Hi, in AWS opsworks, you can create up to 20 Stacks by default. Every stack can hold up to 20 layers, 20 instances, and 20 apps.
These default AWS account limits allow you to launch up to 20 Amazon EC2 instances.
