Worth Reading: The blue disco ball

We deal with procurement departments every day. It’s a fact of modern day corporate life. But this week, I’ve had to respond to so many RFPs asking for “blue disco balls,” (my metaphoric name for a specific kind of middle management error that most vendors, suppliers and even solutions providers love most), I’m thinking about hanging one over my desk. What is a “blue disco ball?” Here’s a story I wrote last year about every senior executive’s worst nightmare and every vendor’s holiday bonus all rolled into a budget-busting good time. —Shelly Palmer

How do you troubleshoot UCaaS problems? Put a ThousandEyes on it

Cisco Live kicked off this week in Las Vegas. The annual event is where Cisco shows off its latest and greatest innovations, such as the intent-based networking system Cisco announced last week.However, it’s also a forum for many of Cisco’s technology partners to show off their wares in the World of Solutions Expo Hall. One of the more interesting vendors there was ThousandEyes, which demonstrated their network monitoring solution, as well as their new Unified Communications monitoring and management capabilities that provide visibility into the performance and connectivity across Unified Communications as a Service (UCaaS), on premises and hybrid VoIP deployments. To read this article in full or to leave a comment, please click here

Cisco upgrades one IoT platform and announces another

Following Cisco's launch last week of its Digital Network Architecture (DNA), which delivers intent-based networking solutions and services, this week’s Cisco Live event in Las Vegas was highly focused on networking. Only a few announcements were made, but the Internet of Things (IoT) made the cut.Cisco’s approach to IoT has been difficult to grasp because it crosses so many divisions. Its largest IoT unit, Cisco Jasper, is exclusively focused on cellular-connected devices.To read this article in full or to leave a comment, please click here

Cisco Vs Ruckus Wireless Systems

There is always a great tussle between Cisco and Ruckus on the wireless upfront where both the vendors are working hard to grip the market with the features they are providing in their wireless domain. Today I am going to talk about the head to head discussion of Cisco and Ruckus, Although  there are lot of point which i am not going to cover here in this discussion.

New Petyawrap Ransomware Attack Again Highlights Critical Need For Security Processes

Whenever there's a new attack on a global scale, the world trusts the Internet a little less. Today we are concerned with the many reports about this new ransomware attack called "Petyawrap", "Petrwrap" or an older name of "Petya."

The sad fact is: this new attack exploits the same vulnerabilities in Windows systems as last month's WannaCry attack. 

Fixes have been available for most Windows systems since March 2017!

The same tips Niel Harper provided last month to protect against ransomware also apply here.

Patching Not Enough to Stop Petya

Voluminous amounts of information have already been disseminated regarding the “Petya” (or is it “NotPetya”? [1]) ransomware that hit the Ukraine hard [2] along with organizations such as “the American pharmaceutical giant Merck, the Danish shipping company AP Moller-Maersk, the British advertising firm WPP, Saint-Gobain […]

What Cisco’s new programmable switches mean for you

To help ring in the 2017 New Year, CNN wanted to do a live shot from a Royal Caribbean cruise ship, but had an issue: “They were concerned about being out at sea, would they have the ability to live-stream?” says Royal Caribbean’s CIO Mike Giresi.The answer was yes, and the live-shot went off without a hitch, in part because the ship’s Cisco network gear was programmable to prioritize the video trafficAs an early implementer, Royal Caribbean has found benefits from regarding Cisco’s programmable infrastructure as a flexible asset that can be driven by software. “There are huge advantages to looking at the network as a software layer,” Giresi says. “It gives us the ability to create products, drive an experience and deliver services that are integrated with the infrastructure.”To read this article in full or to leave a comment, please click here

Worth Reading: High performance computing poised for change

There is a lot of change coming down the pike in the high performance computing arena, but it has not happened as yet and that is reflected in the current Top 500 rankings of supercomputers in the world. But the June 2017 list gives us a glimpse into the future, which we think will be as diverse and contentious from an architectural standpoint as in the past. —The Next Platform

Epyc win for AMD in the server security battle

While everyone is talking about the impressive performance potential and scale of AMD’s new Epyc server chips, overlooked in all the hoopla are the security features of the chip that may prove just as appealing.To start off, there is the tag team of Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). Secure Memory Encryption allows for full encryption of data stored in DRAM, and SEV allows individual virtual machines to be assigned a unique cryptographic key, thus isolating them from each other as well as the OS hypervisor and administrator layer. These functions are based on a hardware security processor attached to the memory controller with a 128-bit AES encryption engine.To read this article in full or to leave a comment, please click here
