Cisco’s first big developers conference to zero in on IoT, cloud

Cisco initially scheduled its inaugural DevNet Create developers’ conference in San Francisco for what turned out to be the same week in May as Google's wildly popular I/O event in Mountain View (that coy old Google didn't reveal its show dates until late January). So Cisco wound up bumping its new event to the following week “to make sure we don’t take audience away from Google I/O. Okay okay — maybe it’s the other way around…” quipped Susie Wee, VP & CTO of Cisco DevNet Innovations in a recent blogpost.To read this article in full or to leave a comment, please click here

Getting Started with NSX Load Balancing

In my conversations with customers and peers, load balancing is becoming an increasingly popular discussion.  Why you may ask?  Simple, load balancing is a critical component for most enterprise applications to provide both availability and scalability to the system.  Over the last decade we have moved from bare metal servers to virtual servers and from manual deployment of operating systems to using tools like Chef, Puppet, vRA or other custom workflows. In addition to the movement towards virtualization and the API being the new CLI, we are also seeing a movement to Network Functions Virtualization (NFV) where Virtualized Network Functions (VNF) such as routing, VPN, firewalls, and load balancing are moving to software. The value of automation, SDN, and NFV has been proven in the largest networks today and this migration to software has proven to have tremendous ROI. Many companies also want to leverage the same cost effective models.   To get us started, here are the most common questions:

1. Does NSX provide load balancing? Yes, NSX has a feature set that addresses the most common deployment requirements for load balancing in enterprises today.
2. Do you charge more for NSX Edge Load Balancing? No, NSX Load Continue reading

Internet VPN or MPLS for branch office IP phone communication?

Many businesses with branch offices that have IP-enabled phones must decide what type of circuit medium to use for their communication to the corporate headquarters site.Two of the most selected choices are a MPLS circuit or internet VPN. Both solutions have their pros and cons, and what is best can depend on your business requirements. Speed, quality of service (QoS), security and cost are the key factors you should consider when making this decision.Pros and cons of an internet VPN A significant advantage of using an internet VPN for communication is the cost. Most times, a branch site can use its existing internet connection for communication back to its headquarters. Usually, a 10 Mbps internet circuit costs much less than a 10 Mbps MPLS circuit. This can encourage a business to purchase more bandwidth for their branch site.To read this article in full or to leave a comment, please click here

Email-based attacks exploit unpatched vulnerability in Microsoft Word

Attackers have been exploiting an unpatched vulnerability in Microsoft Word for the past few months to compromise computers and infect them with malware.The first report about the attacks came Friday from antivirus vendor McAfee after the company's researchers analyzed some suspicious Word files spotted a day earlier. It turned out that the files were exploiting a vulnerability that affects "all Microsoft Office versions, including the latest Office 2016 running on Windows 10."The flaw is related to the Windows Object Linking and Embedding (OLE) feature in Microsoft Office that allows documents to embed references and links to other documents or objects, the McAfee researchers said in a blog post.To read this article in full or to leave a comment, please click here

Ticked at President Trump, Shadow Brokers dump password for NSA hacking tools

Ticked at President Trump, the Shadow Brokers hacking group released the password for the NSA hacking tools they previously tried to sell.In an open letter to President Donald Trump, the group asked, “Respectfully, what the f**k are you doing?” In broken English, they accused the president of “abandoning ‘your base,’ ‘the movement,’ and the peoples who getting you elected.”After a “quick review” of the tools unlocked with the password, Edward Snowden noted that “it’s nowhere near the full library, but there’s still so much here that NSA should be able to instantly identify where this set came from and how they lost it. If they can’t, it's a scandal.”To read this article in full or to leave a comment, please click here

Curaçao and Djibouti – two new Cloudflare datacenters located where undersea cables meet

Cloudflare has just turned up two new datacenters (numbers 108 and 109). Both are around halfway between the Tropic of Cancer and the Equator. They are located continents-apart, yet share something very-much in common as both of these new data centers are deployed and associated with where undersea cables reach land. Undersea cables have been and still are a growing part of the interconnected world that the Internet represents.

Curaçao, part of the Netherland Antilles in the Caribbean

Curaçao is located in the Southern Caribbean Sea (just north of Venezuela) and has a strong Dutch heritage. Along with Aruba and Bonaire, Curaçao is part of the Lesser Antilles (they are called the ABC islands).

More importantly, Willemstad - the capital of Curaçao is where the Amsterdam Internet Exchange operates AMS-IX Caribbean. Why AMS-IX? Because of that Dutch relationship!

It’s AMS-IX’s goal (along with its local partners) to promote Curaçao as an interconnection location for the Caribbean. Cloudflare is there with all its services ready for that day!

How to improve Dynamic Lock in Windows 10 Creators Update

When Microsoft released Build 15031 of the Windows 10 Insider Preview on February 8, 2017, it added a new OS feature for Bluetooth-equipped devices. It's called Dynamic Lock, and lets you control access to your PCs based on how close they — and your Bluetooth-paired phones — are to them. That is, if the phone you've paired with your PC (it works for laptops, notebooks, tablets and desktops) is not found within radio range of your PC, Windows 10 turns off the screen and locks the PC after 30 seconds have elapsed. Thus, Dynamic Lock makes a dandy new security feature in Creators Update, one that most business users (or their IT departments) will find worth turning on and using.To read this article in full or to leave a comment, please click here
