Software Defined Networks (SDN) in the Wild

Software Defined Network BrainI’ve seen a few articles around the emergence of SDNs in the past couple of weeks and I’ve been hunting around for some references of organisations that have embraced the technology.

There has been a flurry of acquisitions and funding for SDN companies relatively recently:

The market leader is considered to be Nicira so I had a look at their references page to see which companies were investing in SDNs and for what reasons.
From my research it looks like SDNs are being used to increase business agility at this stage. Where it gets very interesting is the potential for SDNs to enable more complex cloud deployments to exist and for customers to be able to provision these more complex cloud environments through self-service portals.

It’s this potential that has me excited. The ability to provision complex cloud implementations quickly means that the enterprise will be moving hard to the cloud as it offers the ability for a more comprehensive “total IT in the cloud” as opposed to one or two applications.

I’d be very interested to see some more details on SDNs that have been deployed and what real world user experiences look like to confirm if these more complex clouds are starting to exist.

Cloud Architecture (Part 1) – The Overview

This post is part one of a five part series of posts on what should be designed into any cloud architecture. In this post, I will be giving a high level overview of what makes up a cloud and in the next 4 posts I will focus in on a particular piece of the cloud.

The entire series will be grouped under the Cloud Architecture category.

Due to the huge amount of technical innovation in the market at the moment there are a number of products that an organisation can purchase to help them build their private or public cloud. Instead of singling out specific products that may be right for some organisations but not others, I will write about capabilities which can then be mapped onto specific products.

The four layered cloud architecture presented in this article will be suitable for public, private and all types of hybrid clouds.
