2 options for deciding open computing standards—neither is great

How should open computing standards, such as the protocols and languages that make up much of the core of the internet, be decided on and handled? It’s not an easy question to answer. But the answer has vast and potentially severe ramifications for almost every company on the planet (at least if you rely on your website for doing any percentage of your business). A recent kerfuffle with the World Wide Web Consortium (W3C), the organization responsible for standardizing much of the web that most people use on a daily basis, has caused many to ask for the shut-down of the W3C and the creation of a new standards body. But is that actually a good idea?To read this article in full or to leave a comment, please click here

Ok, I’m Giving Ubiquiti Networks Another Chance

After quite a few discussions resulting from my Epic Evaluation: Ubiquiti ERPro-8 vs Play-Doh where (spoiler alert!) the Play-Doh™ won hands down after an exhaustive six-month test, I’ve been persuaded to give Ubiqiuti Networks (aka UBNT) another chance. Another two chances, in fact.

Ubiqitui Networks Products

As I said in the evaluation post, I was hesitant about recommending against UBNT products not least because I owned four other UBNT devices (three wireless access points and a 48-port switch). Despite being persuaded to try UBNT again, I strongly maintain my previous recommendation to avoid the ERPro-8 like a wedding invitation from Walder Frey. For the rest of the product range I’ve decided to suspend my previous “NO BUY” verdict and reserve my final judgement while I try out some new additions to my home network and see if they can restore balance to the nerd universe.

I would also like to add that while Ubiquiti’s official Support and RMA channels were no help to me whatsoever when my ERPro-8 was behaving badly, I did appreciate one employee reaching out privately and trying to help. The conclusion for now is that flash itself has indeed become irrecoverably corrupted and the device Continue reading

Forrester: 3 ways IoT can drive business value

You can’t escape the IoT momentum these days. The Internet of Things is being used for everything from saving the rhino from poaching to leveraging stray dogs to fight crime. (No, really, I’m not kidding… check the links!) But even as vendors spend billions to try and grab IoT market share, it’s not always clear exactly how their business customers are supposed to actually benefit from IoT. (The challenges can be equally hard to understand). According to a thoughtful new report from Forrester, the answer lies in three fundamental business scenarios:To read this article in full or to leave a comment, please click here

Introducing Cloudflare Warp: Hide Behind The Edge

Introducing Cloudflare Warp: Hide Behind The Edge

I work at a company whose job it is to be attacked. As I’m writing this, an automatic mitigation is fighting two ongoing DDoS attacks. Any machine that’s publicly routable on the internet today can be a vector for attack, and that’s a problem.

Today we want to turn the tables and give you a new way of exposing services to the internet without having them be directly, publicly routable. Meet Cloudflare Warp.

Introducing Cloudflare Warp: Hide Behind The EdgeCC BY-SA 2.0 image by Christian Ortiz

Playing Hide and Seek with Bots and Hackers

Cloudflare internally runs about 4,000 containers that make up about 1.5K services and applications. Some of these containers need to network with other local containers, and others need to accept connections over the wire.

Every devops engineer knows that bad things happen to good machines, and so our platform operations team tries to hide servers altogether from the internet. There are several ways to do this:

  • Rotate IP addresses
  • Deploy proxies
  • Create firewall rules
  • Configure IP tables
  • Limit connections by client certificate
  • Cross connect with an upstream provider
  • Configure a GRE tunnel
  • Authentication mechanisms like OAuth or OIDC

These can be complicated or time consuming, yet none of them are Continue reading

Down the Rabbit Hole: The Making of Cloudflare Warp

Down the Rabbit Hole: The Making of Cloudflare Warp

In the real world, tunnels are often carved out from the mass of something bigger - a hill, the ground, but also man-made structures.

Down the Rabbit Hole: The Making of Cloudflare WarpCC BY-SA 2.0 image by Matt Brown

In an abstract sense Cloudflare Warp is similar; its connection strategy punches a hole through firewalls and NAT, and provides easy and secure passage for HTTP traffic to your origin. But the technical reality is a bit more interesting than this strained metaphor invoked by the name of similar predecessor technologies like GRE tunnels.

Relics

Generic Routing Encapsulation or GRE is a well-supported standard, commonly used to join two networks together over the public Internet, and by some CDNs to shield an origin from DDoS attacks. It forms the basis of the legacy VPN protocol PPTP.

Establishing a GRE tunnel requires configuring both ends of the tunnel to accept the other end’s packets and deciding which IP ranges should be routed through the tunnel. With this in place, an IP packet destined for any address in the configured range will be encapsulated within a GRE packet. The GRE packet is delivered directly to the other end of the tunnel, which removes the encapsulation and forwards the original Continue reading

IDG Contributor Network: How the hybrid cloud has made the digital transformation possible

Competition in the 21st Century economy is fierce. Consumers are more tech-savvy than ever, as we all carry around more computing power in our pockets than Neil Armstrong took to the moon—and potential customers pay attention to differentiated experiences. Increasingly for all businesses, investing in agile software development is a way to achieve that differentiation.In other words, in the 21st Century, every business is a software business.All that software that’s enabling this transformation toward digital experiences has to run somewhere, and it turns out a hybrid cloud strategy gives businesses maximum choice when it comes to what runs where.To read this article in full or to leave a comment, please click here

Volta GPU Accelerators Hit The Streets

Announcements of new iron are exciting, but it doesn’t get real until customers beyond the handful of elite early adopters can get their hands on the gear.

Nvidia launched its “Volta” Tesla V100 GPU accelerators back in May, meeting and in some important ways exceeding most of its performance goals, and has been shipping devices, both in PCI-Express and SXM2 form factors, for a few months. Now, the ramp of this complex processor and its packaging of stacked High Bandwidth Memory – HMB2 from Samsung, to be specific – is progressing and the server OEMs and ODMs of the …
