Notes from MS Learn AZ-700 Module 3: Design and Implement Azure ExpressRoute – Unit 3: Design an ExpressRoute Deployment
ExpressRoute used to connect on-prem with Azure. Plan decisions prior to deployment of an ExpressRoute Circuit
- ExpressRoute Circuit SKUs
- Three SKUs have different charges
- Local SKU
- Automatically charged Unlimited Data Plan
- Standard SKU
- Select Between Metered or Unlimited Data Plan
- Ingress are free except when using Global Reach
- Select Between Metered or Unlimited Data Plan
- Premium SKU
- Select Between Metered or Unlimited Data Plan
- Ingress are free except when using Global Reach
- Select Between Metered or Unlimited Data Plan
- Local SKU
- Use Azure Pricing Calculator to estimate costs
- Three SKUs have different charges
- Choose a Peering Location
- Azure Region
- Global DCs housing Azure computer/network/storage resources
- Resource Location determins Azure DC or availability zone created in
- ExpressRoute Location (Peering Location)
- May be called Peering Location or Meet-me-location
- Colo where MS Enterprise Edge (MSEE) devices live
- Entry point to MS network – globally distributed allowing connectivity to MS network around the world
- Where ExpressRoute partners and ExpressRoute Direct customers cross-connect to MS network
- Azure regions to ExpressRoute location in geopolitical region
- Check up to date link to these via Azure regions to ExpressRoute locations MS maintained page
- ExpressRoute Connectivity Provider
- Check MS maintained page Service providers by location
- Connectivity through Exchange providers
- If connectivity provider not listed in above, still able to create connection
- Several providers already connected to Eth exchanges
- Connectivity through satellite operators
- Remote and no fiber
- Want to explore other options
- Other options
- Other service providers
- DC providers
- National Research and Education Networks (NERN)
- System integrators
- Azure Region
- Choose the Right ExpressRoute Circuit and Billing Model
- MS various Express Route options based on desired bandwidth. Evaluate current usage as a starting point
- Deterring ExpressRoute based on requirements: keep in mind budge/SLAs
- Choose appropriate SKU and if applicable Metered vs Unlimited within the SKU
- Consider ExpressRoute Direct
- Connects network to closet MS Edge which connects to MS Global Network
- Usage of Global MS Network charged on top of ExpressRoute Direct
- Express Route pricing for metered and unlimited bandwidth details
- Available in range of bandwidths – check with provider for what they support
- Choose a billing model
- Unlimited
- Billing based monthly
- All Inbound/Outbound included
- Metered
- Billing based on monthly fee. Inbound free, Outbound per GB
- Rates vary by region
- ExpressRoute Premium add-on
- Additional Capabilities
- Increased route limits for Azure public/private peering from 4k to 10k routes
- Global connectivity for services. Circuit in any region (exclude national clouds) has access to resource in any other region
- Increased VNet links per ExpressRoute circuit from 10 based on bandwidth
- Additional Capabilities
- Unlimited
