Ways to connect a public cloud to a global router

A VMware-based public cloud can be connected to a to a Selectel global router to route L3-level traffic between public cloud virtual machines and other Selectel products.

You can configure connectivity in one of three scenarios. Each scenario will create a subnet in the public cloud, but the connectivity management capabilities will differ.

	1. New subnet for connecting virtual machines without a client Edge router	2. Linking subnet with add on client Edge router and configuring static routes	3. Public cloud docking subnet with adding a subnet to the client Edge router and configuring a BGP session
Public cloud subnet to connect to a global router	New subnet only, no addition to the client Edge router	Any subnet added to the client Edge router	Any subnet added to the client Edge router
Using a client Edge router (ability to configure NAT, Firewall and other features)	✗	✓	✓
Mechanism for configuring routes between service and client Edge routers	-	Static routes	BGP protocol
Changing the subnetwork composition after configuring connectivity	✗	✓ (you will need to update static routes yourself and create a ticket)	✓ (you will need to complete the route redistribution settings yourself)
