In other words, businesses are often entrenched in "rigid processes, risk avoidance and a mindset of 'it's working, why change?'," which can limit an organization's ability to quickly adapt.To read this article in full or to leave a comment, please click here

Playing cyber defense is not enough to win

While the San Francisco 49ers are leading the NFL in defense, the New Orleans Saints currently hold the number one slot for total offense. In the overall league rankings, though, neither of those two teams rank in the top 10. What's the takeaway? Winning isn't strictly about strong offense or impenetrable defense. NFL league leaders advance to the top because they know how to balance the two; they know how to play the game.To address the growing number of attacks on the US government and private sector systems, President-elect Donald Trump's cybersecurity plan aims to, "Develop the offensive cyber capabilities we need to deter attacks by both state and non-state actors and, if necessary, to respond appropriately."To read this article in full or to leave a comment, please click here

While we don’t have plans to seek an open solution in our DC we are considering ACI or VXLAN with EVPN. Our systems integrator partner expressed a view that VXLAN is still very new. Would you share that view?

US Supreme Court leaves gap in Samsung-Apple patent ruling

The U.S. Supreme Court on Tuesday ruled in favor of Samsung Electronics and its backers in the industry in a design patent dispute with Apple, when in a 8-0 decision it said that “the term 'article of manufacture' is broad enough to embrace both a product sold to a consumer and a component of that product, whether sold separately or not.”But the top court has left a lot unsaid, including by not providing guidance to the U.S. Court of Appeals for the Federal Circuit on how the damages Samsung has to pay Apple for the infringement of smartphone design patents will have to be calculated. That could also delay for a long time the resolution of the patent dispute between Apple and Samsung, which has already dragged on for a number of years.To read this article in full or to leave a comment, please click here

Facebook, Google, World Wide Technology near top of Glassdoor’s Best Places to Work 2017 list

Depending up on how loosely I define "enterprise technology vendor," I'd say about a third of the 2017 Glassdoor Best Places to Work in the U.S. list consists of companies that supply IT professionals and those they support.Facebook (hey, they sell Workplace collaboration tools) is all the way up to #2, rising from #5 last year, and Google (#4), system integrator World Wide Technology (#5) and Adobe (#9) are all among the top 10. Consulting firm Bain & Co., is #1 for the third time since 2012, and replaces Airbnb as top dog this time around in the 9th annual rankings.To read this article in full or to leave a comment, please click here

Learning Environments for OVN

Over the last few days, I’ve added two new Vagrant-based learning environments to my GitHub “learning-tools” repository, both of them focused on Open Virtual Network (OVN). OVN, if you aren’t aware, is part of the Open vSwitch (OVS) project aimed at adding open source network virtualization functionality to OVS. If you’re interested in learning more about OVN, you may want to check out these new learning environments.

Here’s more details on the two new learning environments:

  1. The first one, found in the “ovn” folder of the repository, just builds out a simple three-node OVN 2.6.0 environment running Ubuntu 16.04. This would allow you to run OVN commands like ovn-nbctl, ovn-sbctl, ovs-vsctl, and other related commands to better understand how the components interact with each other and how OVN works.

  2. The second environment, found in the “ovn-docker-ansible” folder, builds on the first one by adding Docker Engine to each node in the environment and adding the OVN driver for Docker networking. In addition to being able to run various OVS and OVN commands, this environment allows you to build OVN-backed overlay networks between Docker containers running on any node in the environment.
