Agility for the Cloud with Juniper and OpenStack
Apr 15, 2013

Cloud computing is transforming the way business is done today, and it’s not hard to see why when you consider all the benefits that the cloud promises: flexibility, business agility and economies of scale. Unfortunately, as you delve deeper into the underlying layers of compute, storage and network, you quickly realize the complexity in managing such an infrastructure in a dynamic environment where workloads are mobile and move all around the data center.

With the advances in server virtualization, it is possible to deploy applications within seconds. However, making the corresponding changes to the network infrastructure can take hours and sometime even days. In addition, the introduction of virtual networking components such as virtual routers and switches, along with overlay technology, makes the task of orchestrating the various pieces of the data center infrastructure quite a challenge.  In order to truly realize the benefits of cloud computing, there is a need to orchestrate between these different components.


Juniper’s OpenStack Integration

This is where OpenStack comes in. OpenStack provides the ability orchestrate compute, storage and network, all in concert with each other.  OpenStack, an open platform that prevents vendor lock-in and enables organizations to deploy an agile cloud infrastructure, aims to deliver a simple yet powerful solution for all types of cloud deployments that is flexible, easy to deploy and scalable. Juniper is a member of the OpenStack community and embraces the philosophy of open standards by optimizing its networking solutions for OpenStack.




OpenStack has three major components:  Nova for compute, Quantum for networking, and Swift for storage.  Juniper provides Quantum plug-ins that simplify the network configuration for the deployment of private, public and hybrid clouds through a set of standard APIs. Moreover, Juniper offers Quantum plug-ins that allow customers to manage their physical as well as their virtual networks, resulting in faster deployment of multi-tiered data center applications. Juniper’s Quantum plug-in can also be used to automate orchestration of overlay networks, enabling customers to rapidly deploy services on existing networking infrastructure.


Today Juniper has Quantum plug-ins to manage the EX series, QFX series and Qfabric switches.  Also supported is native L3 capabilities with the virtual network software overlay (from Contrail acquisition). Over time, these will continue to be loosely coupled components and Juniper will continue to support OpenStack and Quantum on all of its networking platforms.  Across these loosely coupled, modular components, Juniper will deliver enhancements at the solution level that is more secure, interoperable and scalable. 


Juniper’s Collaboration with Cloudscaling

OpenStack derives its strength from the community and ecosystem around it.  Cloudscaling, an early member of this community, has deep domain experience in scaling virtualized data centers and elastic cloud environments for dynamic applications and understands the challenges SP and enterprise customers are facing as they move past SDN pilots.


Today, Cloudscaling and Juniper Networks announced a partnership that will integrate Juniper’s virtual network control technology—developed by Contrail—into Cloudscaling’s Open Cloud System (OCS). Together, Juniper and Cloudscaling will address the unfulfilled needs of cloud networks that require a turnkey elastic cloud infrastructure that is open and can seamlessly interoperate with existing and emerging heterogeneous networks.


Juniper’s (Contrail) Virtual Network Controller technology is more than a simple emulation of a Layer 2 network. It solves many of the problems inherent in other designs that compromise the dynamic scaling capabilities that application developers expect of a Layer 3 network—IP reachability and network services including advanced security, horizontal scaling and fault tolerance. With the Contrail controller and OCS, customers get what they expect: architectural and behavioral compatibility between Layer 2 and Layer 3 topologies that simplifies automation and supports today’s enterprise applications and tomorrow’s hybrid deployments.


While the first step of the collaboration is the integration of Contrail technology into Cloudscaling’s OCS to provide Virtual Private Cloud capabilities, we will continue to develop new capabilities and engage in partnership activities later this year. A demo of the Juniper plug-ins can be seen at the upcoming OpenStack Summit April 15-18, 2013. You can find Juniper in booth number C7.
