DMVPN Cisco is, effectively, a solution that allows different branch locations using the same resources to communicate directly and safely with one another via public WAN or internet connections, rather than having to use an internal network. The way that it does this doesn’t utilize a permanent VPN connection between the various sites, but rather through a centralized architecture that can apply VPN protection and granular access controls on an as-you-need-it basis. As such, when communications are open or access has to be granted to specific digital resources, it applies the security features of a VPN on a more selective basis. DVPN also integrates modes of communication, such as the VoIP system, into the protections of a VPN.

Reduces the cost of secure communications and connections between branches by integrating VPN with communication practices.
Allows for easier branch-to-branch communications and connections through a centralized system.

Hub and Spoke Network Architecture 
As mentioned, the Hub and Spoke Network Architecture is a way to efficiently manage the endpoints that are being secured. There are three different phases, each of them suitable for different configurations. However, in general, the hub is used to configure the protocols by which the connections are secured, and these protocols are then applied to the spokes (or endpoints) of the network. This system can be centralized to ensure that allow spoke-to-spoke tunnels first go through the hub, or can be decentralized to cut the hub out entirely.

Dynamic Multiple VPN (or DMVPN) is a complex topic, but it’s a security configuration that could allow businesses that use a wide range of remote endpoints (or flexible endpoints that move location often) to make sure they can keep the security of their network in place, which making sure it’s flexible and not prohibitive in costs.
