Installing Cisco Catalyst 9800 Wireless Controller for Cloud on GCP
The Cisco Catalyst 9800 Wireless Controller for Cloud is a virtual controller running Cisco IOS XE. Most of the Cisco IOS XE features are available on the cloud controller and you can choose to deploy the controller software on Google Cloud Platform (GCP).
To deploy a Cisco Catalyst 9800 Wireless Controller for Cloud on GCP, you must create a project with the following resources: virtual machines, interfaces, virtual private cloud (VPC) networks, routes, public IP addresses, firewall rules, and storage. Resources that exist in different projects can only connect through an external network.
Google Compute Engine instances can run the public images for Linux and Windows Server that Google provides as well as private custom images that you can create or import from your existing systems. Compute instances use SSH public-key authentication. Certain Compute Engine resources live in regions or zones. Resources that live in a zone, such as instances or persistent disks, are referred to as zonal resources.
Other resources, like static external IP addresses, are regional. Regional resources can be used by any resources in that region, regardless of zone, while zonal resources can only be used by other resources in the same zone. A firewall enables you to specify the protocols, ports, and source IP ranges that can reach your instances using security groups. Static IPv4 addresses are used for dynamic cloud computing. Metadata, also known as tags, allows you to create and assign your GCP compute resources.
GPC VPC Concepts
A VPC network, sometimes just called a network, is a virtual version of a physical network, like a data center network.
You can launch your GCP cloud resources, such as GCP compute instances, into your VPC.
You can specify an IP address range for the VPC, add subnets, associate security groups, and configure route tables.
You can optionally connect your VPC to your own corporate data center using an IPsec GCP managed VPN connection, making the GCP Cloud an extension of your data center.
