Tips for migrating applications to Software Defined Networks

Although vendor-written, this contributed piece does not advocate a position that is particular to the author’s employer and has been edited and approved by Network World editors.Software Defined Networking (SDN) is one of the hottest trends in security and networking right now. Many enterprises are considering moving to virtualized networks such as VMware NSX as part of an overall shift from relatively inflexible hardware-based architectures to nimbler, faster, more scalable virtualized deployments.But as with any migration project, careful planning and management is required. Here we look at the steps involved in an SDN migration and what you need to consider at each stage.To read this article in full or to leave a comment, please click here

PlexxiPulse—Products for Success

As the industry transitions into the next era of IT, the flood of data and application growth is forcing Cloud-based network architectures to change radically (for more info take a look here).

ITBusinessEdge: Striving Toward Unified Enterprise Infrastructure
By Arthur Cole
Most enterprises are already realizing some of the benefits of cloud computing in the form of lower capital and operating costs, better scalability and access to more modern, robust infrastructure.

Worth Reading: In the Trenches with OpenStack

In a sense, and oversimplifying a bit, OpenStack is an automation framework for Linux that just happens to allow Windows instances to run on KVM, just like the Azure cloud and Azure Stack are similar extensions to Windows Server that just so happen to also support Linux instances on Hyper-V. There have been a dozen releases of OpenStack since that time, on a six-month cadence of April and October launches that, interestingly enough, have also regularized the pattern for Linux operating system launches, too. -via the next platform

Connectivity did not appear to be the problem as IP Connectivity was there and MIB walks were successful, however some interesting errors were still getting reported on the NMS. As I captured the packets to verify this connectivity, I […]

Cybersecurity whistleblowers: Get ready for more

But according to multiple experts, it will be.“It” is the cybersecurity whistleblower – an employee who sees a flaw, or flaws, in his or her company’s network security, brings the problem to management but gets ignored or punished – marginalized, harassed, demoted or even fired.And then the worker either goes public or files a complaint with a federal regulatory agency like the Securities and Exchange Commission (SEC).Such a scenario is unlikely to end well – almost certainly for the company (if the complaint is credible) and perhaps even for the whistleblower, notwithstanding laws meant to protect them.To read this article in full or to leave a comment, please click here

Facebook, Google, Twitter, Woz, Trump, McAfee, Snowden, and more take sides on Apple vs. the FBI

Apple is challenging a federal court order to help access an iPhone used by one of the shooters in the San Bernardino terrorist attack, claiming that doing so would create a “dangerous precedent.”Now, other tech companies and politicians are publicly debating whether Apple’s dead-set protection of user privacy is justified and whether the FBI has a right to enter people’s iPhones via a “backdoor” to ensure national security. Shortly after Apple CEO Tim Cook posted an open letter detailing Cupertino’s refusal, tech leaders, presidential candidates, and other public figures began taking sides.To read this article in full or to leave a comment, please click here
