Benefits
- Mobile devices can connect to Microsoft cloud services over a private network without going through the public internet.
- Private connectivity to Microsoft services can be achieved via SIM-based mobile lines without the need for a dedicated leased line.
- Centralizing BGP settings on the OCX-Router simplifies configuration.
Notes
- Ensure that AS numbers and network segments do not overlap.
- Internet connectivity is required for services not supported by MAPS, Windows Update, and endpoints such as CDN services used by Microsoft 365 that are provided by non-Microsoft parties. In this design pattern, internet connectivity is provided by Internet Gateway. Please contact Microsoft for details on supported services.
- An East-West redundant configuration is required to meet the SLA standards for XaaS Connection.
- XaaS Connection does not support IPv6.
