Nuage Networks: Unconstrained Networks for the Cloud Age
Jan 15, 2015
Houman Modarres, Senior Director of Marketing, Nuage Networks. More than ever, CIOs are challenged with growing application needs, security and compliance, and ways to minimize overall costs. With compute resources now fully elastic, networks need to match a flexible consumption model across private and public clouds. In this session, we'll discuss innovative ways SDN technology can automate policy-based network connectivity throughout and across enterprise and public cloud data centers. This allows network administrators to set up policies once and apply them automatically across locations, users, and applications. We'll also highlight how SDN's benefits can be extended to your entire data center assets, virtualized and bare metal alike.

Where are they needed in existing solutions?
1. Getting out of the Datacenter
“Back to Square 1”: complex VLAN stitching
2. Supporting Bare metal servers
L2 only services & limited feature capability
Gateway
The Role of Gateways
The Network shouldn’t need a Gateway to get to the Network!
No gateways needed for WAN connectivity in Nuage SDN 2.0 solution
Implicitly a fully distributed routing & switching solution
