Failure to use DNS, IP addresses embedded in the code, ignoring the physical realities (like bandwidth and latency)… the list of mistakes that eventually get dumped into networking engineer’s lap is depressing.
It’s easy to reach the conclusion that the people making those mistakes must be stupid or lazy… but in reality most of them never realized they were causing someone else problems because nobody told them so.
Read more ...At Networking Field Day 12, we heard from a number of vendors that offered solutions to some common enterprise network problems, from management, to security, and more.
However, there were a few presentations that didn’t seem directly applicable to the canonical network admin’s day-to-day. This was made clear by some comments by delegates in the room, as well as others tweeting about the presentation.
Intel, for instance, spent a significant amount of time discussing the Data Plane Development Kit (DPDK), which provides a different way of leveraging CPU resources for fast packet processing.
In their presentation, Intel explained the various ways that they’ve circumvented some of the existing bottlenecks in the Linux kernel, resulting in a big performance increase for applications sending and receiving data on the network. DPDK operates in user space, meaning the traditional overhead associated with copying memory resources between user and kernel space is avoided. In addition, techniques like parallel processing and poll mode drivers (as opposed to the traditional interrupt processing model) means packet processing can be done much more efficiently, resulting in better performance.
This is all great (and as a software nerd, very interesting to me Continue reading
Across industries, the race is on to digital transformation. It’s all about business innovation and redefinition. The transformations are huge: Tesla isn’t just a car manufacturer; it’s a software business that makes cars. CITI is a software business that makes loans. GE is a software business that makes industrial equipment.

Like most of the customers we talk with, your business is also going through a transformation. Lots of change. Lots of disruption. Lots of innovation. More apps, representing more services and new business models. More lines of business empowered to make decisions about the IT they’ll use to take their innovations to market. And there’s no doubt that a huge enabler of all of this has been the cloud.
Consider what some of the leading industry pundits are predicting:
