Open Source Foundational Fatigue: Is It Growing?

By | Blog | No Comments

There was an article a few weeks ago regarding “foundation fatigue” with regard to the Linux Foundation. This article touched on a few key points, but among them was the “fatigue” felt by the participants in the Linux Foundation projects when it comes to the cost of playing, which can approach $500,000 for some companies. The question of “pay to play” is touched on, but not really discussed a whole lot in the article. The angle I’d like to talk about on this topic is more along the lines of: are…

OpenStack is MANO? No…No, It Is Not

By | Blog | No Comments
There was an article on Tech Target about a year ago with the question, "Are OpenStack and NFV MANO interchangeable?"  A colleague stumbled on this recently and asked my opinion on the topic, how true it may have been then and how true it may be now. I can see where people that don't get what MANO is could ask this question. The short answer is that OpenStack is a part of MANO, specifically the VIM. Of course, as this is a blog post, I am going to give a little longer answer...

The Current State of NFV: Virtual Network Functions

By | Blog | No Comments

  This may be one of the shorter blogs in this series, as it is very straightforward. In this one I want to focus on Virtual Network Functions, where they are today and where they are headed. In recent years, as cloud environments have become more and more common, vendors have begun creating virtualized versions of their network gear. Whether it is Nokia/ALU, Juniper, Cisco, or whoever, they all have a version of their major products that they have inserted a “v” in front of to enter the virtual arms race….

The Current State of NFV: Standards

By | Blog | No Comments

There are two standards out there right now that have strong momentum. One being the ETSI NFV standard that has been around for quite a while, and the other being the recently open sourced Enhanced Control, Orchestration, Management and Policy (ECOMP) architecture from AT&T based on the work done as part of Domain 2.0. ETSI has been the leader in this space, and is the standard that almost everyone is using. It is also a less complicated view of what is required to successfully create and manage an NFV environment. There…

The Current State of NFV: Introduction

By | Blog | No Comments

We are going to be posting a series of blogs over the next few weeks to cover where we see the NFV landscape right now, the issues we see still outstanding, an assessment of the maturity of various layers to the NFV reference architecture (considering both the ETSI NFV and AT&T ECOMP frameworks), and where we see things moving in the future. Itential has spent the last 2 years or so working with clients in a hands-on capacity trialing various tools and solutions for SDN and NFV. We have at a…

Disaggregation and the Operational Nightmare It Presents

By | Blog | No Comments

One of the big trends discussed at the OpenStack Summit in Austin a few weeks ago was the idea of disaggregation. While traditional thinking in the network world has been to aggregate as much as possible; in the NFV world the dominant model is quite the opposite. First you have OpenStack itself, which is a conglomeration of dozens of projects integrated together to create your cloud environment. Every executive I have witnessed when first seeing the details of what this really means has a bit of a freak out moment. The…

So What’s Up With MANO?

By | Blog | No Comments

The Management and Orchestration (MANO) stack in the ETSI NFV model is a place full of interesting, and confusing at times, ideas. Many vendors have very different ways of looking at the functionality provided in that area. For reference, below is the standard ETSI NFV framework, with some of the underlying and surrounding components added: One of the best defined areas within MANO, and most mature, is the Virtual Infrastructure Manager (VIM) component. As such we won’t spend a lot of time on that. OpenStack is the clear leader in this…

So I am Building a Private Cloud, Now What?

By | Blog | No Comments

The question of whether you should be in the cloud or not, in some capacity, should be a forgone conclusion at this point. There is value to be had in the cloud for all businesses, whether big or small. Most businesses are probably already using the cloud in some manner, even if it is just through the use of a storage service like Box, Dropbox, or Google Drive. The next question then became whether you should build a private cloud or use a public cloud, such as those offered by…
