An Isolated Network in Apache CloudStack is a private guest network dedicated to a single account. It is not part of a VPC. CMP creates and manages isolated networks through network offerings, virtual routers, public IP behaviour, and optional network billing.
An L2 Network in CloudStack is a layer-2 guest network. It does not deploy a virtual router for L3 services the way isolated or VPC networks do.
CloudStack network types available through CMP. Each type has its own guest network model, routing behaviour, and package requirements.
A Shared Network in CloudStack is a guest network that can be used by multiple accounts within a zone (subject to CloudStack scope and admin configuration). Unlike isolated networks, it is not dedicated to a single tenant’s private router model in the same way.
A VPC (Virtual Private Cloud) in Apache CloudStack is a private, isolated part of the cloud with its own virtual network topology. Customers create VPCs in CMP by selecting a VPC package that maps to CloudStack VPC Offering and VPC Network Offering values.
