Overview

This guide contains the maximum verified scalability limits for Cisco Cloud Network Controller, Release 26.0(3):

These values are based on a profile where each feature was scaled to the numbers specified in the tables. These numbers do not represent the theoretically possible Cisco Cloud Network Controller scale.


Note

Scalability Limits

This section contains scalability numbers for Cisco Cloud Network Controller deployments. The scalability limits differ based on whether it's a single cloud site or a multi-cloud deployment.
