Notes from MS Learn AZ-700 Module 3: Design and Implement Azure ExpressRoute – Unit 8: Connect Geographically Dispersed Networks with ExpressRoute Global Reach
- Use cross-region connectivity to link multiple ExpressRoute Locations
- Various ways to design/implement ExpressRoute based on org requirements
- ExpressRoute connections allow access to
- Microsoft Azure Services
- Microsoft 365 Services
- Connecity to all regions in geopolitical region
- Connect MS in one peering location and access regions in same geopolitical region
- Global connectivity with ExpressRoute Premium
- Enable premium to extend across geopolitical boundaries
- Local connectivity with ExpressRoute Local
- Transfer data costly using Local SKU
- Bring data to ExpressRoute near Azure region desired
- Data transfer included in ExpressRoute port charge
- Transfer data costly using Local SKU
- Across on-prem connectivity using Global Reach
- Enable ExpressRoute Global Reach to exchange across on-prem sites via connecting ExpressRoute Circuits
- Connect private DCs together through two ExpressRoute Circuits
- Cross DC traffic uses MS network
- Rich partner connection ecosystem
- Connectivity to national clouds
- MS operates isolate clouds for special geopolitical regions and customer segments
- ExpressRoute Direct
- Provides opp to connect direct to MS Global Network using peering locations.
- Offers dual 100Gbps connectivity in active/active
- Is private/resilient connection of on-prem to MS Cloud
- Can access services e.g. Azure and MS 365 from corp DC
