BrandPost: Resilience at Edge Computing Sites Is Resilience for the Whole IT Environment

As edge computing deployments get under way, organizations need to make their edge computing sites resilient. As the saying goes, “you’re only as good as your weakest link,” so if edge computing locations are allowed to be the weakest link in a multi-location environment, the entire network surely will suffer.You can’t have a truly resilient IT deployment without resilience at these edge computing sites. So organizations have to harden these sites with best-in-class technology as they do at centralized and regional data centers. Organizations need redundancy, security and management controls designed to prevent downtime.To read this article in full, please click here

Context-aware Micro-segmentation with NSX-T 2.4

With last’s week landmark release of NSX-T 2.4,  and the RSA conference in full swing,  this is the perfect time to talk about to some of the new security functionality we are introducing in NSX-T 2.4.

If you prefer seeing NSX-T in action, you can watch this demo which covers Layer 7 application identity, FQDN Filtering and Ientity Firewall. Or if you are around at RSAC in San Francisco this week, swing by the VMware booth. 

Micro-segmentation has been one of the key reasons why our customers deploy NSX. With Micro-segmentation, NSX enables organizations to implement a  zero-trust network security model  in their on-premise datacenter as well as in the cloud and beyond.  A key component making Micro-segmentation possible is the Distributed Firewall, which is deployed at the logical port of every workload allowing the most granular level of enforcement, regardless of the form factor of that workload – Virtual Machine – Container – Bare Metal Server or where that workload resides – On Premise – AWS -Azure – VMC.

NSX-T 2.4 provides significant new security features and functionality such as Context-aware Micro-segmentation, Network (and Security) Intrastructure as Code, E-W Service Insertion and Guest Continue reading

Diving into Technical SEO using Cloudflare Workers

Diving into Technical SEO using Cloudflare Workers

This is a guest post by Igor Krestov and Dan Taylor. Igor is a lead software developer at SALT.agency, and Dan a lead technical SEO consultant, and has also been credited with coining the term “edge SEO”. SALT.agency is a technical SEO agency with offices in London, Leeds, and Boston, offering bespoke consultancy to brands around the world. You can reach them both via Twitter.

With this post we illustrate the potential applications of Cloudflare Workers in relation to search engine optimization, which is more commonly referred to as ‘SEO’ using our research and testing over the past year making Sloth.

This post is aimed at readers who are both proficient in writing performant JavaScript, as well as complete newcomers, and less technical stakeholders, who haven’t really written many lines of code before.

Endless practical applications to overcome obstacles

Working with various clients and projects over the years we’ve continuously encountered the same problems and obstacles in getting their websites to a point of “technical SEO excellence”. A lot of these problems come from platform restriction at an enterprise level, legacy tech stacks, incorrect builds, and years of patching together various services and infrastructures.

As a team of Continue reading

Silo 2: On-Premise with DevOps

I had a great time stirring up the hornet’s nest with the last post about DevOps, so I figured that I’d write another one with some updated ideas and clarifications. And maybe kick the nest a little harder this time.

Grounding the Rules

First, we need to start out with a couple of clarifications. I stated that the mantra of DevOps was “Move Fast, Break Things.” As has been rightly pointed out, this was a quote from Mark Zuckerberg about Facebook. However, as has been pointed out by quite a few people, “The use of basic principles to enable business requirements to get to production deployments with appropriate coordination among all business players, including line of business, developers, classic operations, security, networking, storage and other functional groups involved in service delivery” is a bit more of definition than motto.

What exactly is DevOps then? Well, as I have been educated, it’s a principle. It’s an idea. A premise, if you will. An ideal to strive for. So, to say that someone is on a DevOps team is wrong. There is no such thing as a classic DevOps team. DevOps is instead something that many other teams do in Continue reading

How blockchain will manage networks

Ethernet networking technology is flawed, say some engineers. The problem is it doesn’t have any inherent security built in to it. Ethernet also hard to manage because it's centralized. It’s out-of-date, and it needs revamping, researchers say.One attempt to address the issue is the Marconi protocol, which is a strategy to shift network and packet management over to a smart contract, decentralized chain-based system. Smart contracts are trackable, verifiable transactions. They’re performed through encrypted blockchains and are self-enforcing.To read this article in full, please click here

Wireless spectrum shortage? Not so fast

The wireless industry has always had to deal with regular (and alarming) pronouncements that we're somehow running out of radio spectrum. We’re not. But the misconception regardless gives many IT and network managers pause. After all, if the availability, reliability and especially the capacity of wireless were to degrade to the point of a de-facto shortage, the situation would be dire for communications at the edges of both the LAN and WAN.So let’s start putting to rest any conjecture regarding a spectrum shortage and focus on reality: Thanks to a combination of continual advances in wireless technologies, recent enhancements to spectrum regulatory policy, and novel thinking around spectrum allocation, we can be assured that a “spectrum shortage” is, and will remain, an abstract theoretical concept.To read this article in full, please click here
