Cloud Infrastructure

I was reading through the could infrastructure. It’s going to change the way we work with infrastructure. For me as an infrastructure professional it’s change the environment. Very easy to build the systems. Easy access, easy disconnection and lot more change the way we manage.

My end user desk tops are from cloud. My server’s and application’s are from cloud. I will be keeping a big pipe WAN link, dump terminals, telephones, and LAN connections of these. The entire infrastructure is from cloud. Applications are browser based. All the applications are accessed through an integrated area or form a portal. All the infrastructure is managed cloud provider. Locally no server, no data, no application. More and more mobile workers. Good to see more……

Cisco DMVPN (Dynamic Multipoint Virtual Private Network)

DMVPN is a simple, secure, low cost, scalable VPN-Tunnel. DMVPN supports distributed applications including: data, voice, and video, with QoS. All of this can be done in a secure IPSec VPN tunnel over an Internet connection.  The only change is the IP address of the GRE Tunnel.  The spoke uses dynamic discovery of IPSec tunnel end-points, (other spokes). No IPSec static configuration for each spoke.

Because DMVPN supports multipoint GRE tunneling you can run VoIP, Video, and Multicast services across your secure DMVPN link. Hub-and-Spoke, (H&S) and Spoke-to-Spoke, (S2S). With H&S the design.

It’s a cost effective and secure communication for branch offices.
