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 status to more mundane environmental data about your home and office. to a certain degree this is accurate. The Internet of Things comprises, well, things. But the question that must be asked - and is being asked in some circles - is not only where that data ends up but how organizations are going to analyze it and, more importantly, monetize it. But there's yet another question that needs to be asked and answered - soon. Assuming these things are talking to applications (whether they reside in the cloud or in the corporate data center) and vice-versa, there must be some way to identify them - and the people to whom they belong. There is a... (more)

F5 Synthesis: SDN Services

#SDN #SDAS There's a whole lot more to software-defined networking than OpenFlow... There's a lot of gnashing of teeth and gnawing at industry reports over the apparent reluctance of organizations to jump with both feet into the SDN ring. According to a new QuinStreet Enterprise Executive Brief, SDN deployment among enterprises today stands at only 14 percent. The 2014 Data Center Outlook: Data Center Transformation - Where Is Your Enterprise? results also found that 15 percent of the surveyed enterprises were planning to deploy SDN within the next 12 months. Additionally, 33 p... (more)

Minimal (Network) Exposure

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 made private, that is to say only the object itself can change it directly. Think of it as the difference between an automatic transmission and a standard (stick). With the latter, I can change gears whenever I see fit. The problem is that when I see fit may not be appropriate to the way in which th... (more)

Cloud and Things and Big Operational Data

Software-defined architectures are critical for achieving the right mix of efficiency and scale needed to meet the challenges that will come with the Internet of Things If you've been living under a rock (or rack in the data center) you might not have noticed the explosive growth of technologies and architectures designed to address emerging challenges with scaling data centers. Whether considering the operational aspects (devops) or technical components (SDN, SDDC, Cloud), software-defined architectures are the future enabler of business, fueled by the increasing demand for app...

SDN's Eventually Consistent Network Problem

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 experience services like QoS. Because there is a single entity which has visibility into the state of the network as a whole, it can examine the topology at any given point and make determinations as to where this packet and that should be routed, how it is prioritized and even whether or not it is ...
