Storage is moving to flash, and flash is getting faster, so people keep asking me why I keep talking about latency as if there is a problem. Isn’t faster flash going to just make everything faster? Won’t “the rising tide lift all boats”? Flash media as a storage media is indeed “fas...
Believe it or not, the first data backups were made on paper. Dating back as early as the 18th century, the "technology" was used in the form of paper tapes constructed from punch cards to control the functions of automated machinery such as textile looms. The concept of these cards wa...
Internet of Things (IoT) platforms have evolved. Advances in technology make it possible for facilities to become more data-driven by connecting to energy assets, thereby improving building resiliency and reducing energy costs. By creating an Energy Network of Things, facilities can ma...
Early (very early, in fact) in the rise of SDN there were many discussions around scalability. Not of the data plane, but of the control (management) plane. Key to this discussion was the rate at which SDN-enabled network devices, via OpenFlow, could perform “inserts”. That is, how man...
We live in a hyper-connected, mobility-enabled world, one in which carriers must make drastic changes to how they do business if they are to survive and thrive in the future. Accordingly, great strides have been made over the last three years to prove the viability of Network Functions...
Today, “network device management” means different things to different people, and the reality is that IT organizations do it, or at least do what they consider network device management to be, to vastly varying degrees, including some who do none at all (hopefully this isn’t you). A...
A year ago, I wrote a two-part series on how lower cost, higher performance on-premise storage and nearly free cloud based storage were driving both innovation and disruption in the storage industry. Applying Clayton Christensen's theory of innovation and disruption to the storage ind...
SDN, or software-defined networking, caught on fast among cloud service providers and hyperscale data centers, but enterprises have been slow to embrace these products. This article looks at a few of the obstacles SDN will need to hurdle before gaining mass acceptance among enterprise...

Everyone talks about continuous integration and continuous delivery but those are just two ends of the pipeline. In the middle of DevOps is continuous testing (CT), and many organizations are struggling to implement continuous testing effectively. After all, without continuous testing ...
Amazon and Google have built software-defined data centers (SDDCs) that deliver massively scalable services with great efficiency. Yet, building SDDCs has proven to be a near impossibility for ‘normal’ companies without hyper-scale resources. In his session at 17th Cloud Expo, David C...
Go ahead. Name a cloud environment that doesn't include load balancing as the key enabler of elastic scalability. I've got coffee... so it's good, take your time... Exactly. Load balancing - whether implemented as traditional high availability pairs or clustering - provides the mean...
In my last post I discussed how all major business models are facing a software-enterprise threat, and that IT will need to tackle this head on in order for businesses to remain successful. However: how can previous generation businesses ACTUALLY succeed in this new software-defined w...
I am not sure how many people remember Cisco SANTap. About ten years ago, Cisco introduced a data tapping mechanism in the MDS 9000 fibre channel switches. The idea was to allow the data path to be “tapped” at-will. Tapping in this case meant using a mechanism in the switch to split th...
SYS-CON Events announced today that Key Information Systems, Inc. (KeyInfo), a leading cloud and infrastructure provider offering integrated solutions to enterprises, will exhibit at the 17th International Cloud Expo®, which will take place on November 3–5, 2015, at the Santa Clara Con...
As Marc Andreessen says software is eating the world. Everything is rapidly moving toward being software-defined – from our phones and cars through our washing machines to the datacenter. However, there are larger challenges when implementing software defined on a larger scale - when b...
Software-Defined Networking (SDN) is one of the most interesting developments in networking to emerge in the last decade. The potential to establish a simplified infrastructure and leverage software to dynamically modify existing flow characteristics has the potential to address many c...
