This yr has been fairly vital for Cisco’s multicloud networking software program evolution. Earlier within the yr Cisco launched, together with different thrilling software program options bulletins, Google Cloud Platform (GCP) help for Cisco Cloud Community Controller (CNC), previously referred to as Cisco Cloud APIC. This weblog sequence introduces the GCP help capabilities subdivided into three elements:
Extra in regards to the rebranding and different expanded capabilities on our Modernize your Multi-Cloud Community with Cisco Cloud Community Controller weblog. For brevity, Cisco CNC will likely be used all through the sequence.
Whereas organizations are more and more turning into extra mature with their to the cloud methods, currently there was a shift in focus to within the cloud networking, as additionally noticed by Gartner of their first Market Information for Cloud Networking Software program and subsequent releases. This sequence will present how a cloud-like coverage mannequin will help addressing contained in the cloud challenges with the intention to maintain bettering operations in public cloud environments and augmenting native cloud networking capabilities, as wanted.
Google Cloud sources are organized hierarchically, and the Mission degree is essentially the most related from the Cisco CNC perspective as a tenant is mapped one-to-one to a GCP mission. Cisco CNC is deployed from the Google Cloud Market right into a devoted infra VPC (Digital Non-public Cloud) contained inside a mission mapped to the infra tenant, whereas person VPCs are provisioned in devoted or shared tasks related to their very own tenants throughout the Cisco CNC.
The Cisco CNC structure on GCP is much like that of AWS and Azure, because it additionally helps BGP IPv4 or BGP EVPN to on-premises or different cloud websites utilizing Cisco Cloud Router (CCR) based mostly on Cisco Catalyst 8000v. It additionally helps native GCP Cloud Router with Cloud VPN gateway for exterior connectivity. As for inside cloud connectivity, it leverages VPC Community Peering between person VPCs throughout the identical or throughout areas as illustrated on the diagram under.
A short overview of the Cisco CNC GUI earlier than continuing. The left aspect of the GUI accommodates the navigation pane which could be expanded for visualization of cloud sources or configuration. The applying administration tab is the place one can go to make configurations, or alternatively, use the blue intent icon on the prime proper which offers quick access to numerous configuration choices.
To exhibit how Cisco CNC automates inter-region routing throughout VPCs, let’s construct a easy situation with two VPCs in several areas contained throughout the identical user-tenant mission referred to as engineering. Word that the identical situation might exist with these two VPCs in the identical area, as VPC networks in GCP are world sources and never related to any area, in contrast to subnets that are regional sources.
Step one is to create a Tenant and map it to a GCP Mission as depicted under. The entry sort is ready to Managed Id, which permits Cisco CNC to make adjustments to user-tenant tasks by the use of a pre-provisioned service account in the course of the preliminary deployment.
The configuration under illustrates the creation of two Cloud Context Profiles used as a mapping software for a VPC. It’s contained inside a Tenant and offers the area affiliation to find out which area(s) a VPC will get deployed to, together with regional subnets. Moreover, a Cloud Context Profile is at all times related to a logical VRF.
By creating these two profiles and mapping to VPCs in several areas, every with their respective CIDR and subnet(s), the Cisco CNC interprets them into native constructs within the Google Cloud console underneath VPC networks as seen under. Word that the VRF identify defines the identify of the VPC, on this instance, network-a and network-b.
Cisco CNC GUI offers the identical degree of visibility, underneath Utility Administration the place extra VPCs could be created or underneath Cloud Sources.
For this situation, a route leak coverage is configured to permit inter-VRF routing which is finished independently of contract-based routing or safety insurance policies to be reviewed on half 2 of this weblog sequence. As seen beforehand, the VRF affiliation to a selected VPC is finished throughout the Cloud Context Profile.
Whereas the “Add Reverse Leak Route” choice just isn’t depicted for brevity, it’s also enabled to permit for bi-directional connectivity. On this situation, since it’s only inter-VPC route leaking, VRFs are labeled as inside and all routes are leaked.
Within the GCP console, it automates VPC community peering between network-a and network-b with correct imported and exported routes.
Peering routes are auto generated for each VPCs, together with default routes automated throughout VPC setup.
It is a easy situation with solely two VPCs as to introduce Cisco CNC capabilities in automating cloud networking inside GCP. It goes from provisioning VPCs to establishing route commercials, automating peering, and offering visibility and management over what’s being deployed.
Cisco CNC can automate different eventualities and use circumstances in only a few clicks. These could be single VPC throughout a number of areas or a number of VPC networks in the identical area, throughout the identical or totally different tasks. This permits prospects to scale their cloud environments utilizing a typical coverage mannequin that abstracts native cloud networking and accelerates their cloud journey.
Half 2 of this weblog sequence will present how Cisco CNC may also use contract-based routing together with automating VPC firewall guidelines in GCP by extending the identical coverage mannequin.
