OpenStack Networking Tutorial at ONUG 2015

by Kyle Mestery

With a theme of “Operationalizing Open Networking,” the ONUG Spring 2015 conference is giving voice not only to the technologies enabling open networking, but also to the operational aspects of running these networks. This is encouraging because it means we’ve reached the point where open networking is being used in production. If you look at the Open Source networking stack, you can see the pieces are all there to run a full-fledged open networking stack for production systems: Continue reading

White Box Is So Much More Than CapEx Reduction!

by Rob Sherwood

If there’s only one message you take from my ONUG white box tutorial, it’s this: reducing capital expenditures (CapEx) is not the only reason to move to white box, branded white box (“brite box”) or disaggregated open networking switches and routers. All of these terms translate into one thing: switches that enable you to buy the hardware separately from the software. Continue reading

2015: Year of the Sheep, Network Virtualization, Overlays and Docker

by Srini Seetharaman

The prevalent migration of application delivery from legacy compute clusters to cloud generates relentless pressure on networking staff for new application needs and push for agility, without a corresponding growth in budget. There is also a stigma of the networking team as being part of the cost-center of the organization. On the other hand, the compute and application IT teams rejoice in being part of the revenue-center of the organization. They talk about “Docker”, “Chef”, “Puppet”, “Salt”, “Ansible”, “Nginx”, “Kubernetes”, “Hadoop”, “Storm” and a whole bunch of DevOps-friendly tools and applications, and how the networking is in their way. Understandably, the job of enterprise network architects and operations engineers has become more complex and challenging. Continue reading

IT Organizational Design is Key to Economic Growth

by Nick Lippis

In Global 2000 companies, IT has organized primarily around silos of technologies. There are different silos: the network, storage, application, server/host, virtualization, security groups and more. This model became popular in the mid 1980s when mainframe computing gave way to mini- and personal computers. Remember Apple’s 1984 Superbowl commercial? Big brother wasn’t just IBM; it was the IT organizational model that created huge barriers of entry for new IT products and ideas from enterprise corporations. But as the mainframe market disaggregated and the IT industry segmented, technical professionals were needed to manage each part of the IT service delivery chain. Each IT group or silo developed processes and tools to manage its specific segment of the IT infrastructure besides cultivating unique relationships with vendors of its choice. The model worked, and for the most part, it still does, but at a heavy cost. But just like the shift away from mainframes drove a new siloed IT organizational model, so too are current mobile and cloud computing technologies, and that new IT organizational design model is the Cloud Infrastructure group.
