By now we’ve seen plenty of cost justification on the efficiency of using cloud infrastructure. You can easily Google “Cloud Computing Value” and get a stack of analyst and vendor reports. Or just pop open Amazon’s AWS value calculator and plug in some numbers. There are huge one-time ...
72%. That's an estimate of how much of the IT budget is allocated to simply keeping the lights on (a euphemism for everything from actually keeping the lights on to cooling, heating, power, maintenance, upgrades, and day to day operations) in the data center. In a recent Forrester Res...
Ask two politically opposed people in any given country about the causes of the country’s problems, and guess what? Each will give you an answer filtered through their world-view. Through what they know, and what they believe. That is not to say one is right and one is wrong, both simp...
Some of you will remember Caddyshack - that campy '80s movie in which Chevy Chase often offered crazy advice, like "be the ball." For those of you who don't (because you're too young or were living under a rock), the premise of this particular piece of advice was along the lines of Obi...
It was a long and full day for me at Devops Summit. I could fill a week or more with blogs on ideas I both agreed - and of course, disagreed - with from sessions and panels. But for now, here's a digestible selection. Ephemeral Infrastructure From John Willis (@botchagalupe) sessi...

Thanks for attending one of my recent DevOps talks over the past few weeks in our community!

There are two fairly recurrent memes in IT infrastructure: the There’s an API for that! theme, and the Out of box! theme. It is actually telling that both continue to get play in IT given that they represent polar opposites. Assuming that each has a value, when do you need something th...
It's a great time to be in the business of delivering software. Today, every business needs to leverage software to differentiate its products or services. So, like it or not, every business is in the software business. This theme resonated at the SDLC Acceleration Summit that occurre...
One of the challenges in scaling modern data centers rises directly from an increase in network complexity over the past few years. We can argue why complexity has increased, but it's reasonable to say that scaling data centers means more boxes - more servers, more network gear, more m...
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 ...
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...
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...
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...
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...
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...
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...
Nick Lippis, who writes the eponymously named Lippis Report, had a fascinating report on the differences between enterprise and service provider environments with respect to network virtualization. He observes, through a survey of the ONUG (Open Networking User Group) membership, t...
The term "service chaining" hasn't quite yet made it into the mainstream IT vernacular. It's currently viewed as a technical mechanism for directing packets, flows or messages (depending on where you sit in the network stack) around the network. Service chaining is the answer to "how ...
Infrastructure must balance between applications and the network because otherwise werewolves would cease to exist. In science we're taught that gravity is the law. As it relates to us living here on earth (I can't speak for all you displaced aliens, sorry) there are two gravitational...
The overall networking landscape has been going through a fairly deliberate shift over the past couple of years. Where we used to talk CapEx, we are now talking OpEx. Where we used to talk features, we are now talking about workflows. This change in industry dialogue mirrors the rise o...
In my experience when you work in IT the executive team rarely focuses on your team until you experience a catastrophic failure – once you do you are the center of attention until services are back to normal. It is easy to ignore the background work that IT teams spend most of their da...
I will admit I have been a strong opponent of those listing roles and organizations as DevOps. Primarily because DevOps is a way to do something and creating a role DevOps Engineer is just putting lipstick on the pig for those looking to hire a Linux Sysadmin or infrastructure script c...
As "applications" continue to morph into what we once might have called "mashups" but no longer do because, well, SOA is officially dead, dontcha know, it is increasingly important for a variety of constituents within organizations - from business stakeholders to application owners to ...
Theresa Lanowitz, founder of voke, discusses "Extreme Automation: Software Quality for the Next Generation Enterprise." Learn how service virtualization and other extreme automation technology helps organizations overcome traditional age-old computing problems. We really want to unde...
A survey from the Vanson Bourne market research agency (with CA) late in 2013 indicated that 39% of those surveyed had adopted some form of DevOps and 27% were planning to do so in the near future. Despite this being such a hot topic in the IT sector, and with a high level of take-up, ...
Proponents of pure software infrastructures often point to rapid provisioning (like right now, push a button and blam! Instant scale) as one of the reasons to "go software." Superficially this is true. If your infrastructure is all software (or virtual, if you prefer) then when you nee...
It's that time of the year, when resolutions promising grand changes in our lives are made - and more often than we'd like to admit, broken. Along with the resolutions comes advice on how to make them "stick." In other words, how to make them habitual. Many folks still cite the old ...
A lot of security-minded folks immediately pack up their bags and go home when you start talking about automating anything in the security infrastructure. Automating changes to data center firewalls, for example, seem to elicit a reaction akin not unlike that to a suggestion to putting...

#SDN #Devops #LineRate When you put software into the data path there are some things it better have to make sure it doesn't become a liability

The software-everywhere drumbeat continues to resound across the entire industry. Experts assure us that software can perform as w...

There are a plethora of tactics used to test applications as they move to production. For example, as a developer I've created data and captured data for testing and - my favorite - ignored testing altogether. After all, it worked on my machine. The reason there are so many tactics ...
DevOps is an exciting and far-reaching shift in IT delivery. The promises are tempting: radically higher productivity, lower cost and more reliable systems. So I guess it’s finally time for your IT organization to get on the development-operations (DevOps) bandwagon, right? Everybody’s...
I've been following SSL for a long, long time. Since before the turn of the century, in fact. I devised performance tests back in the day that, on at least one system (back when PCI was still the standard method of enabling SSL hardware acceleration) actually melted circuits on the hos...
CA Technologies says, “For DevOps to work correctly, it must be treated as a movement, not a market for a specific vendor’s products.” As Arlo Guthrie once sang, with three people it is an organization. But if we can find … Feb. 5, 2014 03:00 PM EST  Reads: 17,143
The biggest difference between high-performance teams and more average teams is that the high-performance group actually acts like a team. That statement is so obvious, I am going to let it stand on its own. If you look at most groups, they tend to act less like teams and more like...
Rather than talking about what others should do or consider for their data protection needs, for this post I wrote down some notes using my Livescribe about what I need and want for my environment. As part of walking the talk in future posts I'm going to expand a bit more on what I'm d...
This is the second of a three-part series (read part I here) about how vendors are keeping backup alive, however what they can and should do to shift and expand the conversation to data protection and related themes. Modernizing data protection and what to do about it Building off of...
2014 will likely be a year of dual business goals for forward-thinking senior executives. Responding to ongoing needs for business efficiency and growth, but also adapting to exploit a fundamentally different digital commerce paradigm. Commercial digitalization, based upon the latest ...
