The Policy Charging and Control (PCC) solution consists of the following components:
- Containing the Access, Control and Execution Zones for execution of workflows.
Real-time Data Repository - For storage of runtime information, available to any Execution Zone. This is called Data Repository throughout this document.
Monitoring - For monitoring of the overall solution. Note that monitoring does not apply to Redis.
...
- [CZ01] and [CZ02] - Contain the Control
- [EZ01+DR01], [EZ02+DR02] - Contain the Execution Zones, where the workflows are executed, as well as the Data Repository where all data pertaining to processing is stored. Two [EZs] are required for failover purposes.
...
This instruction is based on the assumption that each "component" above corresponds to one machine, i.e, the names within [] is used throughout the document to describe on what machines the corresponding function is to be installed. Referring to [CZ] means the machines containing all the functions listed in that component.
