If you're an executive that's concerned about the high-cost of proprietary software, you're not alone. If your IT team pushes back whenever Line of Business leaders ask them for feature enhancements that goes beyond the limits of the commercial software packages they've licensed, then ...
The days of completely separate storage network technologies are quickly fading. It feels like it’s only a few years ago that Fiber Channel was the way to create large scale storage networks. Big honking storage devices on a separate network, connected to Fiber Channel switches, connec...
Senior executives at progressive companies have been on a mission -- they're raising the bar of expectations for leaders of their significant investment in business technologies. Providing reliable access to IT resources and reporting on system up-time objectives are unlikely to gain r...
When we think about what’s next, our frame of reference is almost universally anchored to what we are doing now. We look at how things are, and then we aim our sights forward. In some cases, we might make incremental moves ahead; in other cases, maybe we look for improvement by orders ...
Conventional wisdom refers to DevOps as a strategy, an approach, or a movement as some call it. DevOps addresses the idea that Development and Operations need to be aligned well in an application lifecycle, work closely and collaboratively to eliminate inefficiency, reduce bottlenecks,...
A great article of future of cloud IDEs: The Cloud IDE and its impact on DevOps by Chris Riley (@HoardingInfo). The article makes a number of excellent points. Many developers will oppose the Cloud IDE without much consideration. These are all very good points. From my personal exper...
Programmability is in F5's DNA. Since 2001 when we introduced iControl SOAP to the more recent additions such as iRules and iCall. Even looking at our most recent acquisitions you can see the common theme: an architectural vision based on extensibility and programmability. BIG-IQ is ...
The Internet has been buzzing over the recent news of a federal proposal that creates the equivalent of “slow” and “fast” lanes online. The Federal Communications Commission (FCC) voted on Thursday, May 15, 3-2 in favor of a new proposal that enables the creation of Internet fast lanes...
IP Multicast is one of those technologies that most everyone loves to hate. It’s almost the perfect example of how complicated we have made networking. Getting IP Multicast to run depends on several protocols that are all somewhat intertwined or dependent on each, their relationship so...
Pop quiz: Your development team is developing a new mobile application. Should they optimize it for use over a mobile network or over WiFi? Another way to ask that same question is, "Should they provide a great quality of experience for users over a mobile network or over WiFi? And y...
It turns out that a real-time business-process approach to billing, ordering and settlement terms between buyers and sellers benefits both American Electric Power, one of the largest investor-owned electric utilities in the U.S., and its many vendors. BriefingsDirect had an opportunit...
For many SDN and DevOps enthusiasts, the natural outcome of this wave of technological change is a highly-automated network that is well-orchestrated with surrounding systems and applications. One of the prevailing thoughts is that this level of automation is a well-formed abstraction ...
The UK’s Digital Government program is such a great leadership example, because not only are they pioneering the G-Cloud store, a service catalogue for IaaS, PaaS and SaaS suppliers, but also they are defining ‘Agile Procurement’ practices too. Since the G-Cloud project was aligned un...
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 ...
