Introducing VMware Skyline™

VMware Skyline™: an innovative support technology, developed entirely by VMware Engineering, that provides VMware technical support engineers with extreme visibility into your (customer’s) environment.

Customers with active support subscriptions install the VMware Skyline Collector, a standalone appliance that automatically and securely collects product usage data such as configuration, feature, and performance data.

It then listens for changes, events and patterns and analyzes the information using a robust rules and machine learning engine. The rules engine is where an ever-growing library of support intelligence, product knowledge, and logic is stored to analyze inbound streams of product information. Check out the video and the blog to learn more!

IDG Contributor Network: 6 things IT executives must do to accelerate IoT adoption

Are you ready for the Internet of Things (IoT)? Despite its transformational potential, most organizations are not. In an era of rapid disruption and digital transformation, IT executives and managers must lead the charge. You must bridge the gap between technology, business, engineering and operations. You must be evangelists, teachers, facilitators and innovators. To succeed, I’ve listed six things you must do to accelerate IoT adoption within your organization.Increase your organization’s IoT IQ Start the journey by increasing awareness, knowledge and conversations around IoT throughout the organization.

The Internet of Things goes to school

It appears research universities are a great place to test Internet of Things (IoT) deployments. That’s because they often comprise a microcosm of a wide variety of organizational and technical environments.Gordon Wishon, CIO of Arizona State University, explained the reasoning to Campus Technology this way:To read this article in full or to leave a comment, please click here

Small Site Multihoming with DHCP and Direct Internet Access

Cisco recently (15.6.3M2 ) resolved CSCve61996, which makes it possible to fail internet access back and forth between two DHCP-managed interfaces in two different front-door VRFs attached to consumer-grade internet service.

Prior to the IOS fix there was a lot of weirdness with route configuration on DHCP interfaces assigned to VRFs.

I'm using a C891F-K9 for this example. The WAN interfaces are Gi0 and Fa8. They're in F-VRF's named ISP_A and ISP_B respectively:


First, create the F-VRFs and configure the interfaces:

 ip vrf ISP_A  
 ip vrf ISP_B  
   
 interface GigabitEthernet8  
  ip vrf forwarding ISP_A  
  ip dhcp client default-router distance 10  
  ip address dhcp  
 interface FastEthernet0  
  ip vrf forwarding ISP_B  
  ip dhcp client default-router distance 20  
  ip address dhcp

The distance commands above assign the AD of the DHCP-assigned default route. Without these directives the distance would be 254 in each VRF. They're modified here because we'll be using the distance to select the preferred internet path when both ISPs are available.

Next, let's keep track of whether or not the internet is working via each provider. In this case I'm pinging 8.8.8.8 via both paths, but this health check can be whatever makes sense for your situation. So, Continue reading

Worth Reading: IoT needs a paradigm shift

Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it’s possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other “smart” devices, like door locks, light bulbs, thermostats and the like. In Austria a hotel got threatened by hackers that their guests will be locked out of their rooms, if the hotel doesn’t pay ransom in bitcoins. —Martin Unger @CircleID

Easy data storage services are like fast food

Recently I made the (unfortunate) decision to eat at a particular fast-food establishment. For the sake of this story, let’s call it Shmurger Shming.I didn’t eat at The Shming because the food tastes amazing. Nor did I choose to ingest those Shmurgers because I thought it was, in any way, healthy for me. In fact, I knew full well that eating them would cause not insignificant amounts of gastronomical distress.Which begs the question: Why, on this green Earth, would I make that decision? Why would I do that to myself?Simple. It was convenient, there was very little up-front investment (in time and money), and it was food. Technically. In other words, I was lazy.To read this article in full or to leave a comment, please click here

History Of Networking – Juliusz Chroboczek – Babel Routing Protocol

Babel is a relatively new routing protocol when compared to some of the more well established options, but due to some of its design considerations, it is very well suited for routing on distributed mesh networks. Babel’s creator, Juliusz Chroboczek, joins the Network Collective team in discussing how Babel came about, some of the design decisions when creating it, and what the future looks like for this emerging technology.

Cisco’s IWAN isn’t dead

Earlier this month, Cisco completed the acquisition of SD-WAN vendor Viptela, which it had announced in early May.The companies’ recent news sparked several rumors about the fate of Cisco’s Intelligent WAN (IWAN), with publications writing such articles as “Is the End Near for Cisco’s IWAN?” and “Cisco’s Viptela acquisition could mean IWAN is dying or dead.” The content of the articles isn’t quite as aggressive as the headlines, but the articles have led to a number of misconceptions about what Cisco will do with its SD-WAN solution.To read this article in full or to leave a comment, please click here

Connected IoT is about to become cognitive IoT

Connected devices, also known as the Internet of Things (IoT), will transition to cognitive, predictive computing over the next 12 to 18 months, according to research firm Frost & Sullivan. IoT, overall, is also about to grow rapidly, the firm says. It predicts a 20.3% Compound Annual Growth Rate (CAGR) worldwide leading up to the year 2023. That will be a jump to 45.3 billion devices, up from 12.4 billion IoT devices in 2016, it claims.Cognitive computing, which is when a machine is programmed to simulate human thought processes, will partly drive that growth, along with further microelectronics development and “ubiquitous connectivity,” says Frost & Sullivan, a research and consulting firm that specializes in business disruption.To read this article in full or to leave a comment, please click here
