Node-RED created in an IBM laboratory (UK) is a GUI for wiring up the Internet of Things (IoT)built-on Node.JS. It is possible that some of you have known, or used LabView. LabView is a GUI for wiring up complex laboratory equipment like Voltage sources, measuring instruments, automa...
Technology shifts are creating a lot of chaos, including the way we use words. Cloud. SDN. Multi-tenant. Instances. They're all inter-related and seem to have different meanings depending on who's trying to sell you what today. That's more than a tad bit disconcerting, because you kno...
On this side is a variant of SDN: network service virtualization (NSV). On the other side is an emerging application architecture: microservices. Where they meet lies devops. One of the most fascinating things to watch in the technological shifts occurring today is to see them all con...
It comes as no surprise that the CEO of Target has resigned in the wake of their massive data breach. The 2nd executive, if I remember correctly, to resign due to the mishap. Data breaches are costly according to the most recent Ponemon 2014 Cost of Data Breach Study: United States and...
As a SaaS business matures, the importance and value of SaaS metrics increase. Most SaaS businesses begin their journey down the SaaS metrics path by tracking recurring revenue in relation to customer acquisition costs. After building a solid customer base, churn becomes a priority. Th...
As public and private cloud adoption continues to skyrocket, it’s becoming more and more clear that Database-as-a-Service (DBaaS) is hugely important to users. This isn’t really news, as much as it’s a confirmation of what many were seeing much earlier in the cloud industry’s maturatio...
It means you can't use "network" protocols to make intelligent decisions about applications any more. Back in 2000 (or 2001, I forget exactly), I got to test a variety of bandwidth management appliances. Oh, they were the bomb back then - able to identify (and classify) applications b...
How many of you actually fill out the registration cards that come with your kid's toys? Anyone? Anyone? Bueller? Bueller? That's what I thought. Me neither. Not as a parent and certainly not as an adult. After all, they were just going to use it for marketing, right? Fast forwa...
In reviewing some opportunities for Plexxi this week, I was reminded that we have made things very hard on ourselves. Through no one’s fault but our own we have created monsters of networks that are impossible to maintain, debug, diagnose and understand. I have been lucky in my career...
This week's "bad news" with respect to information security centers on Facebook and the exploitation of HTTP caches to affect a DDoS attack. Reported as a 'vulnerability', this exploit takes advantage of the way the application protocol is designed to work. In fact, the same author who...
AppDynamics is excited to unveil details behind our new Application Intelligence Platform which is the technology foundation for the AppDynamics portfolio of performance monitoring, automation and analytics solutions (transaction analytics was also announced today). Today’s software d...
Forgotten in the outcry over the NSA snooping on people’s online activities is that our favorite websites and online marketers do the same thing every day. However, profiling, tracking and third-party leaks will soon be tools of the past. Re2You is re-imagining how we use the Internet....
How many different network protocols can you name? There are, of course, a set of staples just about everyone knows: IP, ARP, VLAN, TCP, UDP, DNS, HTTP, SSL, TLS, SMTP, FTP, SMB, CIFS, 802.1q, 802.1ad. Then there are recent additions like VXLAN, NVGRE, SPDY. But we could fill post ...
Cisco would like to use the phrase IoE – Internet of Everything. But the common term is IoT (Internet of Things) these days. It refers to any device that has an IP address, and can communicate. I will be speaking at an IoT Expo in San Francisco on May 5th. and my session is called – Bi...
Being from the Hawaiian Islands, the annual gathering of the Kohola (humpback whales) is always a spectacular view. They can get over half their body out of the water and administer a cannonball body slam splash like you’ve never seen before. Most of the internet thinks they breach to ...
Way back in the early days of the Internet scalability was an issue (the more things change...). One of the answers to this problem was to scale out web servers using a fairly well-proven concept called load balancing. Simply put, distribute the load across web servers to make sure eve...
From a cost perspective, the networking dialogue is dominated by CapEx. Acquisition costs for new networking gear have historically been tied to hardware, and despite the relatively recent rise of bare metal switching, networking hardware remains a high-stakes business. But SDN is chan...
Take a moment to consider the things we put up with on a daily basis because they have been understood and accepted as the status quo. Perhaps the old adage, “better the devil you know than the devil you don’t,” rings no truer than for traditional on-premise data storage systems. Sure,...
Over the past few years, the SaaS community has gained a solid understanding of SaaS financial metrics, as well as many of the operational principles required to achieve them. However, there has always been an obvious gap between what happens on the top line and what happens on the gro...
In the beginning there was a simply acronym: MTTI (mean time to innocence). Weary after years of costly and time-consuming war room battles, IT organizations turned to AppDynamics to give an objective application-level view of production incidents. As a result, application issues are s...
We've talked before about the bifurcation of the network, which is driven as much by the evolution of network services from "nice to have" to "critical" as it is by emerging architectures. The demarcation line in the network stack has traditionally been - and remains - between layers 3...
Like moving to IPv6, simply picking up your existing network architecture and moving it to a completely new one is not going to happen overnight. There will undoubtedly still be "traditional" networks hanging around even when SDN adoption is considered mainstream and fully mature. That...
While organizations spend the next few days and weeks patching OpenSSL vulnerabilities, the realization is setting in that we may never know the full extent of the damage caused by Heartbleed. Although Heartbleed was only announced in early April, it has actually been present in OpenS...
Earlier this week, Ethan Banks wrote a very nice article about Mellanox’s dual spine and leaf network in support of a large amount 10GbE access ports. After describing the scaled up network design, he reviews 8 observations about the design, not to point out good or bad, but merely to ...
Last week was a crazy week for information security. That's probably also the understatement of the year. With the public exposure of Heartbleed, everyone was talking about what to do and how to do it to help customers and the Internet, in general, deal with the ramifications of such a...
Like every one I am updating my terminology to reflect the shift that occurred – Business and technical executives immediately get that when combined with a world of smart, connected devices then Cloud computing only makes more sense. We have entered an age where IoT Cloud Computing...
This past weekend, like many of you, I started getting the blood curdling password resets from a bunch of OpenSSL affected sites. I also got a few emails from sites indicating that I had nothing to worry about. Bad news, good news. Probably the biggest security story thus far for 2014 ...
When I visit clients to talk about DevOps, I usually ask them what their monitoring strategy is. Too often, the answer I hear is "We use Nagios". I think Nagios is a great tool, but it sure is not a strategy. Nagios does a good job of monitoring infrastructure. It will alert you when y...
One of the most powerful aspects of the Internet of Things is the process of synthesis it achieves; it provides a mental model for people to associate and relate a number of different technologies under one umbrella concept and trend. Therefore one early quick win is a simple taxonomy...
OpenStack. OpenDaylight. SDN. Cloud. It's all about abstraction, about APIs and "software-defined" (which really means software-controlled, but this is neither the time or place to get into that debate). It's about jailbreaking the network. Enabling access to features and functionalit...
There are a variety of opinions on the seriousness of Heartbleed being put forth ranging from "it's not the end of the world" to "the sky is falling, duck and cover." Usually the former cites the relatively low percentage of sites impacted by Heartbleed, pegged at about 17% or 500,000 ...
Not too long ago, it took even the most successful entrepreneurs several centuries or at least decades to reach a valuation of a billion and thus become a member of the exclusive Billionaire Boys Club*. Families like the Rothschilds, the Waltons or the Brenninkmeijers have indeed built...
Despite claims that there exists (or will, look out!) a mythical "god box" for the enterprise data center, capable of performing every data center function imaginable, it remains, well, mythical. Efforts to effectively secure the data center and the applications it delivers therefore r...
HTML5 is still one of the most discussed topics amongst us technical types. The key challenge, however, has remained unanswered for a long time. How do you effectively wrap HTML5 for use in native mobile applications? Unfortunately I do not have a universal answer, but I do have a s...
If the CEO of the company has anything to say about Lenovo's standing in the PC industry, the company won't stop until massive growth is achieved. In a series of recent buying sweeps, Lenovo has bought Motorola Mobility for a whopping $2.91 billion from Google and also acquired the ser...
What is the “3rd Platform” of IT? It comprises of the cloud, mobile, social, and big data products. According to IDC, “3rd Platform technologies and solutions will drive 29 percent of 2014 IT spending and 89 percent of all IT spending growth”. Much of that growth will come from the “ca...
We love analogies. No matter what the topic, analogies are a great way to explain something in a different context to make a specific point with a frame of reference that may be more familiar to those we are making a point to. There is one that seems to come back over and over again in...
There’s a new craze occurring in homes, highways, workplaces and everywhere imaginable – the Internet of Things or as I like to call it, The Internet of Nouns. Sensors, thermostats, kitchen appliances, toilets and almost every person, place or thing will have a chip capable of connecti...
The industry often talks about how the data center perimeter is expanding,necessarily, due to technological shifts such as cloud and mobility and BYOD. But that isn't really the case. If you look closely, you'll see that the perimeter is actually shrinking, getting tighter and tighter...
As the fourth installment of HBO’s ever popular hit series, Game of Thrones, premiered this past Saturday, millions of viewers were frustrated to find out HBO Go crashed due to overwhelming demand. A discouraging sign for fans who wanted to watch the highly-anticipated premiere. TechC...
