Configuration Staging - Is An enhancement to the rules engine that allows customers to test configuration changes in a staging environment before using the configurations in production.
Rules Engine - Receives an overhaul of existing rules engine to make it more intuitive for customers, enabling them to create custom rules to fit their traffic needs.
The "Configuration" is the heart of a customer's interaction and usage of a CDN. Any settings, preferences, parameters and optimizations are written into the configuration files for an account. Placing updated configurations in a staging environment will enable a customer to change the configuration for their account in some way or another and then determine the impact that these changes will have without actually modifying the configuration that is in the production environments.
A CDN takes advantage of "Rules" to analyze and modify the traffic that is traveling to and through the Customer's or CDN's servers. Creating a policy of customized rules allows a customer to analyze broadly or very specifically for particular scenarios and perform complex actions on the traffic that interacts with the content on their websites or services they provide.
