As organizations work to make big data broadly available in the form of easily consumable analytics, they should consider outsourcing functions to the cloud. By opting for a Big Data as a Service solution that handles the resource-intensive and time-intensive operational aspects of big data technologies such as Hadoop, Spark, Hive and more, enterprises can focus on the benefits of big data and less on the grunt work.
The advent of big data raises fundamental questions about how organizations can embrace its potential, bring its value to greater parts of the organization and incorporate that data with pre-existing enterprise data stores, such as enterprise data warehouses (EDWs) and data marts.

TL;DR: Your servers are no longer servers, they’re now just containers for functionality. Powershell DSC represented a huge step forward for configuration management on Windows, and Puppet’s DSC module compounds that step for both configuration management on Windows and the usefulness of Puppet. This Puppet module means that you can now effectively control both Windows […]

A few months ago VMware launched NSX version 6.2, and I asked my friend Anthony Burke to tell us more about the new features. Not surprisingly, we quickly started talking about troubleshooting, routing problems, and finished with route-health-injection done with a Python script. The end result: Episode 50 of Software Gone Wild. Enjoy!
Since spending quality time with complexity theory when writing Navigating Network Complexity, I’ve started seeing the three sided complexity problem crop up all over the place. Remember this? Fast, high quality, cheap: choose two. We face this problem in a number of ways in network design. A recent (last year) paper by researchers from University of Louvain, ETH Zürich and Princeton have figured out how to engineer traffic in a straight IP network (no MPLS) by injecting false nodes into the shortest path tree. You can read the paper here, and listen to Ivan’s podcast with one of the authors here.
What’s interesting to me is the direct tradeoff this paper represents between the amount of state in the control plane and optimal traffic flow through the network. Adding state does, in fact, allow you to optimize traffic flow—at the cost of calculating the state and injecting it into your control plane (in this case OSPF). This state must be carried through the network, increasing the amount of state in the network, and it must change as traffic flows change, increasing the speed at which the state changes in the network. Finally, this idea opens up a new interaction surface Continue reading
