# T1 - Exceptions
In general keep exceptions in views, not in models. 
Put exceptions in models just when very necessary like to make process atomic or multiples tasks, 
even in this case think if is not better split the method in multiple methos and treat exception in each method

# T2 - Always try to name the relationships

# T3 - Concentrate business logic into models methods and Managers

# T4 - Always help_text

Roles
- Or you might want to allow a mobile app to use AWS resources, but not want to embed AWS keys within the 
app (where they can be difficult to rotate and where users can potentially extract them). 
Sometimes you want to give AWS access to users who already have identities defined outside of AWS, such as in your corporate 
directory. Or, you might want to grant access to your account to third parties so that they can perform an audit on your resources.

Fixed Performance Instances (e.g. M3, C3, and R3)

Burstable Performance Instances
    - T2
    - Accrue CPU Credits when they are idle
    - It stores them in its CPU Credit balance for up to 24 hours.
    - If and when your t2.small needs to burst to more than 20% of a core, it draws from its 
    CPU Credit balance to handle this surge seamlessly
