#devops #SDN #SDAS Whether it's DevOps or SDN, a key goal is the reduction of variation (complexity) in the network. Kirk Byers at SDN Central writes frequently on the topic of DevOps as it relates (and applies) to the network and recently introduced a list of seven DevOps princip...
#SDAS #webperf Consumers are increasingly performance-sensitive, which means every microsecond counts. In the five seconds it takes you to read this, 60% of your visitors just abandoned your site. Another 20% were gone before you even hit the first comma, and 30% of all them are purch...
Application delivery, as defined as its own little corner of the network industry, has been fairly focused on assuring the performance, security and availability of applications since its inception back around 2003. Oh, the ways in which those three core tenets have been supported by a...

#cloud #loadbalancing Scalability requires load balancing, but it doesn't require efficient or cost-effective load balancing. It's not the first time we've heard the statement that cloud can be too expensive and I doubt it will be the last. This latest episode comes from A...
#devops #webperf Continuous Measurement needed. Performance. Speed. Velocity. Quality of experience. No matter what particular turn of phrase we use to describe it, the reality is that we'll try a whole lot of things if it promises to improve application performance. Entire marke...

#IAM  #IoT     If you listen to the persistent murmur in the market surrounding the Internet of Things right now, you'd believe that it's all about sensors. Sensors and big data. Sensors that monitor everything from entertainment habits to health statu...

One of the primary principles of object-oriented programming (OOP) is encapsulation. Encapsulation is the way in which the state of an object is protected from manipulation in a way that is not consistent with the way the variable is intended to be manipulated. The variable (state) is ...
It's an application world; a world that is rapidly expanding. With new opportunities and markets arising driven by mobility and the Internet of Things, it is only going to keep expanding as applications are deployed to provision, license, and manage the growing sensors and devices in t...

#HTTP #ietf #webperf #infosec Despite the hype and drama surrounding the HTTP 2.0 effort, the latest version of the ubiquitous HTTP protocol is not just a marketing term. It's a real, live IETF standard that is scheduled to "go live" in November (2014). And it changes e...
One of the benefits of SDN is centralized control. That is, there is a single repository containing the known current state of the entire network. It is this centralization that enables intelligent application of new policies to govern and control the network - from new routes to user ...

Inarguably one of the drivers of software-defined architectures (cloud, SDDC, and SDN) as well as movements like DevOps is the complexity inherent in today's data center networks. For years now we've added applications and services, and responded to new threats and requirements from th...
#cloud #SDAS #AWS And you can try it out for free...  June 30, 2014 (The Internet) Today F5 Networks, which delivers solutions for an application world, announced it had completed jumping through the hoops necessary to offer an hourly (utility) billing model for its BIG-IP VE (Vi...
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...
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...

#Cloud #devops  Cloud and software-defined architectures have brought to the fore the critical nature of load balancing. 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,...

It's probably no surprise that I have long advocated the position that hybrid cloud would eventually become "the standard" architecture with respect to, well, cloud computing. As the dev/ops crowd at Glue Con was recently reminded by the self-styled "most obnoxious man in cloud", Josh ...

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...
When people write about software-defined architectures being "disruptive" to the network they're doing a bit of a disservice to just how much change is occurring under the hood in the engine that drives today's businesses. The notion of separating control and data planes is superficial...
