Global Cloud Network
The Teridion Management System (TMS) uses real-time analytics from Teridion Measurement Agents (TMAs) to determine where to deploy Teridion Cloud Virtual Routers (TCRs). Quite a mouthful! These TCRs are deployed via TMS-driven APIs across all major cloud operators, leveraging congestion data as well as cost and geography.
Customer (a SaaS company, for example) traffic is shunted off the ISP layer (the underlay) at a TCR that is logically close to the customer’s end user. The traffic then follows the best TCR path (the overlay) to a TCR located logically close to the origin server. The connection is all but lossless and predictable between TCRs. Customer traffic is segregated through the creation of Virtual Backbone Networks (VBNs) that traverse the TCRs. Depending upon the customer requirements, there are multiple TCR resiliency levels, and via the TMS, the capacity of the network scales on-demand.
The GCN, though at its core a segmented control and data forwarding plane architecture, differs from a SDN in important ways. SDNs (and even SD-WAN) are designed for more ‘managed’ environments in terms of scalability and stability. In most cases they also infer a controller architecture. The Teridion GCN is designed to handle the uncertainties of the global Internet backbone and the different availabilities of cloud operators. It is also capable of scaling 10x or even 100x capacity in short order without operator intervention. Lastly, the TCRs, full-fledged virtual routers, may operate autonomously. The TCRs are instantiated on x86 compute resources in our cloud operator partners, in the same way as compute and storage, but we do not consider ourselves to be an NFV solution in the conventional definition.
