Gartner: IT spending will drop 8% as COVID-19 hits enterprise wallets

Gartner this week said that IT spending across the globe is projected to total $3.4 trillion in 2020, a decline of 8% from 2019 due to the impact of the COVID-19 pandemic.In January Gartner had forecast Worldwide IT spending to total $3.9 trillion in 2020, an increase of 3.4% from 2019.[Get regularly scheduled insights by signing up for Network World newsletters.] Gartner’s new forecast says all market segments from enterprise software to communications service will experience a decline in 2020, with devices and data-center systems experiencing the largest drops in spending. To read this article in full, please click here

How HashiCorp Widened the Reach of the Consul Service Mesh

HashiCorp has expanded its Consul network control plane by widening its scope for different highly distributed services and environments — while simplifying and expanding its compliance and policy management capabilities. By adding gateway options and compliance features with today’s release of Consul 1.8, HashiCorp has made the control plane able to manage many different environments in a single interface, the company says. These might include services and applications running in containers, Kubernetes or virtual machines (VMs) on bare metal, traditional data centers or multicloud environments that are often widely dispersed geographically. “We are useful to customers because we offer a layer across [different environments] with a single management plane. The challenges customers have is they have many services that sit outside of service mesh, such as traditional applications, and need to bring them into the same fold,” HashiCorp, told The New Stack. “So how can services talk to your applications within your service mesh, and how do the applications in the service mesh talk out? Consul 1.8 solves that problem.” Consul 1.8’s audit logging and single sign-on (SSO) features (which are part of the enterprise version) Continue reading

Build an OpenStack/Ceph cluster with Cumulus Networks in GNS3: part 1

Introduction

I must have built OpenStack demos a dozen times or more over the past few years, for the purposes of learning, training others, or providing proof of concept environments to clients. However these environments always had one thing in common – they were purely demo environments, bearing little relation to how you would build OpenStack in a real production environment. Indeed, most of them were “all-in-one” environments, where every single service runs on a single node, and the loss of that node would mean the loss of the entire environment – never mind the lack of scalability!

Having been tasked with building a prototype OpenStack environment for an internal proof of concept, I decided that it was time to start looking at how to build OpenStack “properly”. However I had a problem – I didn’t have at my disposal the half-dozen or so physical nodes one might typically build a production cluster on, never mind a highly resilient switch core for the network. The on-going lockdown in which I write this didn’t help – in fact it made obtaining hardware more difficult.

I’ve always been inspired by the “cldemo” environments on Cumulus Networks’ GitHub and my first thought was Continue reading

Announcing the Launch of the Global Encryption Coalition

Logo of Global Encryption Coalition

Today, more than 30 civil society organizations joined in launching the Global Encryption Coalition, to promote and defend encryption in key countries and multilateral gatherings where it is under threat. The new coalition is led by a Steering Committee consisting of the Center for Democracy & Technology (CDT), the Internet Society, and Global Partners Digital.

“The spread of COVID-19 has underlined the necessity of secure, private internet communications. Those who are fortunate enough to have strong internet connections are likely sharing increasing amounts of sensitive data online. At the same time, governments around the world are considering policies that put the security of that data at risk,” said Greg Nojeim, CDT’s Senior Counsel and Director of the Freedom, Security and Technology Project. “Encryption enables people to have private and secure digital lives.”

Working together with a membership that will quickly grow to include companies and technologists, CDT and the Coalition will help activists on the ground in key countries where it is under threat, like Canada, Australia, India, and Brazil, beat back proposals that would weaken encryption. “The Coalition will alert technologists to encryption threats around the world, and create mechanisms through which they can deliver expert analysis Continue reading

IPv6 Buzz 051: How The Work-From-Home Movement Affects IPv6 And The Internet

The IPv6 Buzz crew examine how the recent increase in working from home have affected Internet traffic as a whole--and IPv6 in particular. Will recent developments push IPv6 closer to a "tipping point"? What is VPN breakout and how is it impacted by IPv6? They discuss these topics and more.

Feedback from Another SD-WAN Fan

I don’t know what’s wrong with me, but I rarely get emails along the lines of “I deployed SD-WAN and it was the best thing we did in the last decade” (trust me, I would publish those if they’d come from a semi-trusted source).

What I usually get are sad experiences from people being exposed to vendor brainwashing or deployments that failed to meet expectations (but according to Systems Engineering Director working for an aggressive SD-WAN vendor that’s just because they didn’t do their research, and thus did everything wrong).

Here’s another story coming from Adrian Giacometti.

What is IoT? The internet of things explained

The internet of things (IoT) is a catch-all term for the growing number of electronics that aren't traditional computing devices, but are connected to the internet to send data, receive instructions or both.There's an incredibly broad range of ‘things’ that fall under the IoT umbrella: Internet-connected ‘smart’ versions of traditional appliances such as refrigerators and light bulbs; gadgets that could only exist in an internet-enabled world such as Alexa-style digital assistants; and internet-enabled sensors that are transforming factories, healthcare, transportation, distribution centers and farms.What is the internet of things? The IoT brings internet connectivity, data processing and analytics to the world of physical objects. For consumers, this means interacting with the global information network without the intermediary of a keyboard and screen (Alexa, for example).To read this article in full, please click here

How IoT will rescue aviation

A biotech company that develops sensors to detect explosives and other chemicals on planes and in airports is teaming up with Airbus to create a sensor that could detect passengers who are positive for COVID-19.California-based Koniku and Airbus, which have been working since 2017 on contactless equipment that sniffs out chemicals, are trying to adapt that technology to sniff out pathogens, says Osh Agabi, founder and CEO of Koniku, in a blog post.To read this article in full, please click here

The Hedge Episode 35: Peter Jones and Single Pair Ethernet

When you think of new Ethernet standards, you probably think about faster and optical. There is, however, an entire world of buildings out there with older copper cabling, particularly in the industrial realm, that could see dramatic improvements in productivity if their control and monitoring systems could be moved to IP. In these cases, what is needed is an Ethernet standard that runs over a single copper pair, and yet offers enough speed to support industrial use cases. Peter Jones joins Jeremy Filliben and Russ White to discuss single pair Ethernet.
