IDG Contributor Network: Why is tape declining in the backup world?

The numbers don’t look good My favorite source of numbers for the tape industry used to be the Santa Clara Consulting Group.  They’d been tracking the use of tape in the backup and recovery industry since 2008 and had been a great go-to for such data. They showed a steady decline in number of units shipped, both in terms of drives and media.  Unfortunately, it looks like they stopped doing these services in 2014.Gartner’s most recent report on what media types people are using to do their backups is a pretty solid source of data, though. They’ve got data going back to 2009 that shows the percentage of people that are backing up directly to tape (D2T), backing up to disk then copying to tape (D2D2T), backing up to disk with no tape component (D2D/D2D2D), or backing up to the cloud (D2C/D2D2C).  While tape is used in most datacenters in one way or another, the percentage of companies using tape in any way is steadily declining. Companies are clearly moving to D2D or D2C techniques.  What are the reasons behind this trend?To read this article in full, please click here

Creating a single pane of glass for your multi-cloud Kubernetes workloads with Cloudflare

Creating a single pane of glass for your multi-cloud Kubernetes workloads with Cloudflare

(This is a crosspost of a blog post originally published on Google Cloud blog)

One of the great things about container technology is that it delivers the same experience and functionality across different platforms. This frees you as a developer from having to rewrite or update your application to deploy it on a new cloud provider—or lets you run it across multiple cloud providers. With a containerized application running on multiple clouds, you can avoid lock-in, run your application on the cloud for which it’s best suited, and lower your overall costs.

If you’re using Kubernetes, you probably manage traffic to clusters and services across multiple nodes using internal load-balancing services, which is the most common and practical approach. But if you’re running an application on multiple clouds, it can be hard to distribute traffic intelligently among them. In this blog post, we show you how to use Cloudflare Load Balancer in conjunction with Kubernetes so you can start to achieve the benefits of a multi-cloud configuration.

To continue reading follow the Google Cloud blog here or if you are ready to get started we created a guide on how to deploy an application using Kubernetes on GCP and AWS Continue reading

The Cost of Cybercrime

Most people paying attention would expect that the cost of cybercrime has gone up in recent years. But a new report has put a number on it: Worldwide cybercrime costs an estimated $600 billion USD a year.

That’s up from $500 billion USD in 2014, the last time security vendor McAfee and think tank the Center for Strategic and International Studies released a similar study. The new estimate amounts to 0.8 percent of global GDP, up from 0.7 percent in 2014.

“Cybercrime is relentless, undiminished, and unlikely to stop,” writes report author James Lewis, senior vice president at CSIS. “It is just too easy and too rewarding, and the chances of being caught and punished are perceived as being too low.”

Lewis points to poorly-protected IoT devices as a particular problem. Insecure IoT devices “provide new, easy approaches to steal personal information or gain access to valuable data or networks,” he writes. They also power botnets that can create massive denial-of-service attacks.

Among the other reasons for the growth in the cost of cybercrime:

  • Cybercriminals are embracing new attack technologies.
  • Many new Internet users come from countries with weak cybersecurity.
  • Online crime is becoming easier through cybercrime-as-a-service Continue reading

IDG Contributor Network: It’s time to start thinking differently about IoT

A steady churn of stunningly useless consumer devices has turned IoT into a running joke in the tech community. Worse yet, some applications have gone beyond the silly and into the realm of scary – like internet-connected teddy bears that record your kids (and skimp on security). But there’s a whole other side to IoT. Far removed from the world of consumer gadgetry, IoT is being used behind the scenes to solve real problems and create real value across a wide variety of applications and industries.To read this article in full, please click here

EVPN with MPLS Data Plane in Data Centers

Mr. Anonymous (my most loyal reader and commentator) sent me this question as a comment to one of my blog posts:

Is there any use case of running EVPN (or PBB EVPN) in DC with MPLS Data Plane, most vendors seems to be only implementing NVO to my understanding.

Sure there is: you already have MPLS control plane and want to leverage the investment.

Kathmandu, Nepal is data center 123

Kathmandu, Nepal is data center 123

Kathmandu, Nepal is data center 123

We said that we would head to the mountains for Cloudflare’s 123rd data center, and mountains feature prominently as we talk about Kathmandu, Nepal, home of our newest deployment and our 42nd data center in Asia!

Five and three quarter key facts to get started:

  • Nepal is home to the highest mountain in the world.
  • Kathmandu has more UNESCO heritage sites in its immediate area than any other capital!
  • The Nepalese flag isn’t a rectangle. It’s not even close!
  • Nepal has never been conquered or ruled by another country.
  • Kathmandu, Nepal is where Cloudflare has placed its 123rd data center.
  • Nepal’s timezone is 5 hours 45 minutes ahead of GMT.

Mountains

The mountainous nation of Nepal is home to Mount Everest, the highest mountain in the world, known in Nepali as Sagarmāthā. Most of us learn that at school; however there’s plenty of other mountains located in Nepal. Here’s the ones above 8,000 meters (extracted from the full list) to get you started:

  • Mount Everest at 8,848 meters
  • Kanchenjunga at 8,586 meters
  • Lhotse at 8,516 meters
  • Makalu at 8,463 meters
  • Cho Oyu at 8,201 meters
  • Dhaulagiri I at 8,167 meters
  • Manaslu at 8,156 meters
  • Annapurna I at 8,091 meters

Viewing Cisco Proximity with SpectrumView

I wanted to share a quick trick for troubleshooting Cisco Proximity. For those that haven’t stumbled onto this particular technology, Proximity is a feature in Spark Connected and Traditional Cisco Video Endpoints that provides a pairing channel for screen sharing. Specifically, the codec announces its presence and connection information via 22khz audio stream. The client device then uses that connection information to make a connection over the network and share the screen with the codec. Since 22khz is beyond what the human ear can hear, there is a need for some other tool to check for its presence.

The tool I use to check for the pairing channel presence is SpectrumView and is available in the Apple App Store.

SpectrumView

There are a couple options that need to be manually configured before the tool displays the higher frequency used for the pairing process:

  • Recording – Audio Sampling Rate 48000
  • Display – This may be necessary to adjust if you don’t see anything. I typically set mine to about 15dB

With the proper settings and within range of a proximity enable device, some output should be visible just above 20kHz.

BrandPost: DIY Not the Best Approach to SD-WAN

Wide area networks (WANs) were not designed for the load that most enterprises need them to handle today. Demand for data across the distributed enterprise is growing exponentially; virtually all enterprises are using cloud technology in some form; and the Internet of Things is growing expanding the scope of networks far beyond servers, PCs, tablets and smartphones. So, it shouldn’t be a surprise that many are eagerly turning to software-defined WANs (SD-WANs) to deal with those growing needs.SD-WANs reflected the ongoing movement to software-defined IT assets and increasing reliance on virtualization to make those assets available where and when needed. But few organizations have the fortitude—or budget—to rip and replace core pieces of their existing infrastructure, such as MPLS, which provides Class of Service prioritization and Quality of Service management.To read this article in full, please click here

BrandPost: Sorting Through SD-WAN Options

Most enterprises rely on a combination of MPLS and IPsec to implement virtual private networks (VPNs) across the organization’s wide area network (WAN). But the emergence of mobile devices and cloud-based applications, along with enormous growth in data volumes, has them scrambling for more flexible, more cost-effective options. Many expect software-defined network (SDN) technologies, and in particular SD-WANs, to provide the solution, but sorting through all the options can be a challenge.Backed by venture capital, SD-WAN appliance vendors have been popping up all over the place. But appliance-based point solutions represent somewhat of a do-it-yourself scenario, and it’s important to understand whether they’ll inhibit or enhance what an enterprise can gain from SD-WAN deployment.To read this article in full, please click here
