In this chapter, we will work with throttling rules to limit the usage of our RESTful Web Service. We don't want to process requests until our RESTful Web Service runs out of resources, and therefore, we will analyze the importance of throttling rules. We will take advantage of the features included in the Django REST framework to manage different versions of our web service. We will gain an understanding of:

• Understanding the importance of throttling rules
• Learning the purpose of the different throttling classes in the Django REST framework
• Configuring throttling policies in the Django REST framework
• Running tests to check that throttling policies work as expected
• Understanding versioning classes
• Configuring the versioning scheme
• Running tests to check that versioning works as expected
