I’ve managed, marketed, and implemented quite a few application and infrastructure offerings in the course of my career. This varied set of experiences has taught me that the line between a robust product and a true platform can be fuzzy.
For example, it’s frequently difficult to tell if a given offering is a product dressed as a platform or a platform that’s dressed as a product. Similarly, it’s hard to figure out if an offering is a true Software Defined Networking [...]

Cloud has won the hearts and minds of enterprise IT shops across industries, and they’re looking for next-generation telecommunications services to support these cloud computing environments. As such, telecommunications providers need to embrace the distributed nature of cloud-based service offerings, to launch network services targeted for c [...]
Virtualization brought significant changes in networking by moving the edge of the network in the server itself. This led to a significant increase of network endpoints and new requirements for the network in terms of provisioning for both speed and flexibility. To a certain extent the ideas of virtualization and cloud gave birth to the whole notion of software defined networking (SDN) since the network needed to keep up with the deployment speeds of virtual machines (VMs).
Docker and microse [...]
Docker and Containers are taking the application development world by storm, but with all of their benefits there are some limitations and challenges. One key challenge is security between containers, especially when those containers are in different security zones. The early adopters of containers at scale (e.g. Google, Twitter, Apple) have fairly consistent security requirements across their applications. In areas like Financial Services and Medical Records, companies have widely different sec [...]
Whether you’re overlay optimistic or overlay pessimistic about the way datacenter networks are going to evolve, there was a lot of proof in the virtual pudding at the recently concluded Open Networking User Group (ONUG) meeting in the Big Apple. The Overlay Working Group had issued their 2015 testplan challenge, and the results of their testing were published & discussed last week.
Admittedly and firmly among the Overlay optimistic, I see clearly now the leading indicators for a real sh [...]
Nuage Networks first shipped Virtualized Services Platform (VSP) in 2013. Since then, VSP has been operational in some of the largest data centers around the world, making the cloud “real” by making the network as accessible and fungible as the compute side of the house.
OpenStack powers the cloud orchestration layer in most of our installations. And, to meet our customers’ networking needs, we have been busy building a partner ecosystem. Among other functionality, we have deploy [...]
Some time ago, we discussed the principles of overlay networks and the design requirements for the physical infrastructure that can support such networks. As discussed in this blog, almost every communication channel we have today is indeed using one or more overlays - IP over Ethernet, IP over Optics, Wireless access over GRE tunnels over IP over Optics etc.
The idea of decoupling services from core networks, maintaining a simple core and pushing intelligence at the edge has been fundamental [...]
Imagine driving on a humid rainy day with the windows of your car fogging repeatedly. When time and safety are of the essence, this quickly becomes more than a nuisance. Especially in situations of busy traffic and rapidly changing road conditions, visibility is critical.
A leading indicator of the real adoption of private clouds by demanding enterprises is that the same observation is being made. Safely and productively expanding private cloud deployments often means breaking through an oper [...]
Last week I attended Australia’s largest technology expo in Melbourne Australia. The show was called Connect Expo and it brought eleven diverse technology areas under the same roof. Attendees could listen to world experts on such topics as cloud, big data, future health, connected education, digital marketing and UAV/drones…well I did say diverse… and I can vouch that if you put a drone the size of a car in a booth you generate a lot of foot traffic.
Nuage Networks supported the event w [...]
I have just returned from presenting at the China SDN/NFV conference for the second time. In 2013, I remember explaining Software Defined Networking (SDN) and what it meant for the future of our industry. Two years later, my subject is very advanced which in many ways reflects the speed at which our customers have accepted & deployed this technology.
This year’s talk focused on workloads mobility and how they can dynamically consume network resources regardless of their location (or bor [...]
