Data is processed on the infrastructure the operator designates, under its control.
ATC reviews the platform the operator prioritizes and proposes the appropriate configuration. Sizing and review are provided at no cost.
- Review of the platform and the network interfaces
- Sizing according to the operator's infrastructure
- Staged proposal: module, platform or delegated operation
