Frank Yue, Sr. Technical Marketing Manager, discusses Network Function Virtualization and how service providers are deploying it within their infrastructures. Frank talks about the relation to SDN, the functionality it provides SP’s, the NFV...
There's a common movie and television trope (known as the Third Wheel) that revolves around a guy, his girlfriend and either his or her "bestie". You know it - it's the bestie hates girlfriend or boyfriend trope, and it's a...
Immutable infrastructure, which I think is more appropriately called disposable infrastructure, has been enjoying a reinvigorated life with the success of Dockers and containerization over the past year. Too, DevOps has played a role in...
"Programmability in the network" is a wordy yet simpler way to describe the extension of network capabilities through the use of software-defined techniques. See what I mean? In any case, whatever you want to call it, there are two...
Please find the English language post, by Lori MacVittie, from which this was adapted here. この2つには違いがあります。そして、その違いはユーザがどのような技術を選択するかに大きな影響を与えることになるので重要です。SDNが、初めてメジャーな技術として登場した2012年のInteropで...
Whether you've bought into DevOps or NetOps or SDN or SDDC (or all of them) as a way to operationalize the data center, one thing is clear: organizations are desirous of ways to deliver applications  and their infrastructure faster wit...
Today F5 is announcing a new F5® BIG-IQ™ 4.5. This release includes a new BIG-IQ component – BIG-IQ ADC. Version 4.5 isn't just another dot release. IMHO, this release should have been numbered 5.0. With this release, BIG-IQ is finally...
The Law of Software Entropy as described by Ivar Jacobson et al. in "Object-Oriented Software Engineering: A Use Case Driven Approach": The second law of thermodynamics, in principle, states that a closed system's disord...
On August 12th I wrote of the announcement and subsequent release of the F5 device package for Cisco APIC. A big day for both organizations, bringing to the world a partnership able to complete the SDN vision by way of managing both low-level...
There is a difference. One is strategic, one is tactical. One lays the foundation for the future, the other sweeps the past under the rug. There is a move (again) in technology that pits consolidation as the be-all and end-all of tactical...
What is human latency? No, I’m not referring to how quick you can pull a table cloth - something my mother insisted I stop trying, and failing miserably at, at a young age. In technology circles, human latency refers to the delays incurred when...
I'm sure there are few people who have escaped some form of reporting or metrics collection in their careers. Pondering my various roles and responsibilities for a moment, I think I've measured almost everything: SPAM emails caught,...
Microservices. Service-oriented, but not SOA, this architecture is becoming more common as mobility and time to market drives up the ante in this high stakes game of applications. But just what are microservices? If you want a more complete and...
#DevOps #SDN We keep saying that, does it mean what you think it means? Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps...
I talk a lot about SDAS (that's Software Defined Application Services) with respect to F5 Synthesis and, well, F5 in general. That's because what F5 Synthesis delivers the ability to easily provision and orchestrate SDAS across a variety...

#SDN #DDoS #infosec Integration and collaboration is the secret sauce to breaking down barriers between security and networking  Most of the focus of SDN apps has been, to date, on taking layer 4-7 services and making them into extensions...
Application services are everywhere
article
#SDAS #SDN Application services are closer to apps than they are the network and like apps, they're everywhere. SDN has begun to recognize that it can't just focus on lower order (L2-4) network services. The bulk of network services...
#SDN #IoT #SDAS Jim Duffy over at Network World had an interesting post on IoT and the intersection of SDN, noting that some claim SDN is critical to the success of IoT while others are in the "it's an enabler" camp. Experts say...
#DevOps #SDN And more importantly, what can I do with it?  So within the realm of software-defined (everything) and DevOps one can find lengthy (and often in depth) discussions on the relevance and indeed importance of programmability to...
1024 Words: IT Syzygy

#SDN #DevOps #Agile A syzygy is an astronomical term that describes the alignment of three celestial bodies within a gravitational system. The alignment of three celestial bodies (app dev, ops, the network) within a gravitational system (IT). ...
#DevOps #SDN While some might still be focused on SDN with an OpenFlow-style twist, 30% of the organizations in our survey this summer (report forth coming, I promise!) were looking at SDN to improve time to market. Of those, 73% considered an...
