VPNs (or Virtual Private Networks) are largely understood as a concept by many who are using networked connections that may involve sending and receiving sensitive data. Dynamic Multiple VPN, such as Cisco DMVPN, works to encrypt transmitted data much like a regular VPN. However, they do it in a way that can secure communications between branch offices in particular. It does this using a centralized architecture to provide easier implementation and management for deployments across the entire IT scope of the organization.

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)
