#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 share the notion of "operationalization" as...
#IoT #IDM #SDAS #infosec As the Internet of Things continues to expand (and it is expanding rapidly) the issue of access to applications is going to get a lot more messy. One of the benefits of cloud, so I'm told, is it is "easy access" for everyone. Indeed, it matt...
#AWS #reinvent #linerate #cloud #SDAS Cloud, in all its forms, remains a trend of top strategic importance to organizations across every size, shape and vertical. The importance of hybrid is based largely on the reality that organizations are adopting and migrating to all of the varyi...
#SDAS #cloud #DDoS #infosec It's an application world. But it's also a hybrid cloud, very mobile world, too. Applications might be on-premise, in the cloud or delivered as a SaaS application. Users might be at home, on the road or in the office using a laptop, a tablet a phone or, incr...
#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 of the SDN controller. But HP is taking a diff...
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 share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like...
Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does...
Organizations are turning to cloud not just as an option for applications but also for the network and application services that deliver applications to anyone, anywhere at any time. And not just "in" the cloud marketplace, available for immediate provisioning and deployment, but as pa...
The Internet of Things is only going to make that even more challenging as businesses turn to new business models and services fueled by a converging digital-physical world. Applications, whether focused on licensing, provisioning, managing or storing data for these "things" will incre...
One of the more popular methods of dealing with not just with the explosion of devices but the growing challenge of dealing with growth of compute devices under management in general is virtual desktop infrastructure (VDI). While VDI has been overshadowed of late by newer and shinier T...
Now while we kidding around about naming this wall the "MacVittie-Roberts wall of DOOM", we weren't kidding about the need for better performance monitoring in production. After all, to definitely say that application performance is faster requires that we've measured performance after...
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 principles that are applicable in an article entitled, "DevOps and the Chaos Monkey. " On this list is the notion of reducing var...
When Instagram was sold to Facebook in 2012, it employed only 13 people and maintained over 4 billion photos shared by its 80 million registered users. Internally, Instagram was a small business. Externally, it was a web monster. Filling the gap between those two contradictory perspec...
Certainly, enterprises feel the pressure to transition their networks to next generation architectures like SDN to brace the coming storm that is an app economy. Service providers could provide valuable advice to them on how to do that, if they could yell loud enough over the thunderou...
#HTTP #HTTP2.0 Why that version number is so very important .... It's no surprise that HTTP is the new TCP. Inarguably, more applications are delivered via HTTP than any other. That's including mobile apps, by the way, which are more often than not using HTTP to talk to REST-based API...
#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 both. In the case of SDN, programmab...
When SDN made its mainstream debut at Interop in 2012, there was quite a bit of excitement tempered by the reality apparent to some folks that technical limitations would impact its applicability above layer 2-3 and, perhaps even at layers 2-3 depending on the network. But even then w...
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 API-enabled infrastructure to be important to very impo...
Shellshock, appropriately and of course punnily named, is ravaging the Internet right now. Active exploits continue to grow in number and in complexity. While there are multiple avenues through which this vulnerability can be exploited, the most active one at the moment appears to be ...
Architectural debt is incurred when you don't consider the implications of your choices today on your needs of tomorrow You may recall a previous post which discussed the notion of architectural debt incurred by the network being a significant contributor to the reality that the bul...
#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). The data seems to show some alignm...
#SDN #DevOps Stateful is not stateless. And vice-versa.  
We (as in the industry at large) don't talk enough about applying architectural best practices with respect to emerging API and software-defined models of networking. But we should. That's because as we continue down the path that continues to software-define the network, using APIs an...
Inarguably, the pressure is on "the network" to get in gear, so to speak, and address how fast its services can be up and running. Software-defined architectures like cloud and SDN have arisen in response to this pressure, attempting to provide the means by which critical network servi...
#SDAS #IAM #IoT #Mobile The new requirements for app delivery include a focus on hyperscaling access to applications. A plurality (48%) of enterprises deliver between 1 and 500 applications to consumers and employees. A somewhat surprising 21% deliver more than 1000 applications every ...
The problem with web application performance is directly related to the increasing page size and number of objects comprising pages today. Increasing corporate bandwidth (the pipe between the Internet and the organization) doesn't generally help. The law of diminishing returns is at wo...

#SDAS #SDN #Cloud #SSL #HTTP2.0 F5 continues to pave the way for business to adopt disruptive technologies without, well, as much disruption. The term hybrid is somewhat misleading. In the original sense of the word, it means to bring together two disparate "things" that res...
#F5SOC #malware #2FA #infosec The good news is that compromising #2FA requires twice the work. The bad news? Malware can do it. That malware is a serious problem, particularly for organizations that deal with money, is no surprise. Malware is one of the primary tools used by fraudster...

#SSL Forget #infosec benefits and #webperf implications, SSL just did an end-run around IT and went straight to the business. With fewer than 1/3 of organizations securing apps with SSL, that could be a problem. If the business isn't panicking, it should be.    Goog...
