Open source has had a massive impact on information technology and the web: The Linux operating system, the LAMP stack, browsers, the Android smartphone OS. Individual enthusiasts, universities, and businesses spend enormous resources to build technologies, and then give them away for free. Are they out of their mind? The success of open source shows they are not.
OpenStack, the open source cloud management software, has come into the focus of service providers as a rapidly advancing, cost-effective technology foundation for NFV. With OpenStack, service providers are expecting to escape the tangles of individual vendors and build an open horizontal platform for their future networks.
Large enterprises increasingly resemble public network service providers as they manage access, transport and network routing while controlling devices and sessions. Whether businesses build their own or buy their communications services through a public provider, the IP communications architectures are looking remarkably similar.
“I’ve noticed that both private service operators (CIOs of large enterprises) and public service providers are implementing very similar solutions around the globe,” wrote Oliver Krahn in a recent TechZine article, 6 Steps that Improve Communications Services.

“GM factories reduce production in aftermath of Japan earthquake 2011”, “Hard disk shortage due to Thailand flooding 2012“, “Drug shortages continue to vex doctors”, “China factory fire sends memory chip prices to three-year high (2013)”. Industrial supply chains are becoming increasingly tenuous as they are thinned out and stretched across the globe. Raw materials are available from fewer and fewer specialized suppliers and warehouses are eliminated for just-in-time production. Small, local incidents affect the supply of goods on a global scale.
In the IT industry we are seeing a similar trend. Enterprises are moving their applications and data to the cloud, but this cloud is often highly centralized and not as resilient, free flowing, or efficient as one might think. Amazon Web Services, the largest cloud provider in the world, is serving their global customers from no more than two handfuls of locations. Netflix and other companies have experienced major outages due to single failures in the cloud they used.
So what does this mean for NFV?
By: David Amzallag - Alcatel-Lucent Vice President, Virtual Telecommunications and CloudBand CTO
While network functions virtualization (NFV) introduces new challenges to security, it also presents unique opportunities for addressing security problems due to the unprecedented scale, flexibility, and central control it affords. Compute, storage, and network resources can be optimally allocated and stitched together as required by the security policy. Our approach to address NFV security is based on a recursive, divide-and-conquer methodology, which involves securing the Alcatel-Lucent CloudBand™ NFV Platform, cloud nodes, and the network that interconnects them. CloudBand uses policy-based placement capabilities enabled by the CloudBand Management System to install virtualized functions in their appropriate security zones, and re-uses the security services provided by NFV applications.
I thought it would be a good idea to describe the journey to this approach together with its "making of" episodes.
