Server hardware makers shift production out of China

The supply chain of vendors that build servers and network communication devices is accelerating its shift of production out of China to Taiwan and North America, along with other nations not subject to the trade war between the U.S. and China.Last May, the Trump Administration levied tariffs on a number of imported Chinese goods, computer components among them. The tariffs ranged from 10-25%. Consumers were hit hardest, since they are more price sensitive than IT buyers. PC World said the average laptop price could rise by $120 just for the tariffs.To read this article in full, please click here

SD-WAN Must Tackle the Multidomain Problem

Chris Wade Chris Wade serves as the co-founder and CTO of Itential, a network automation software company focused on simplifying and accelerating the adoption of network automation and transforming network operations practices. SD-WAN (software-defined networking in a wide area network) was originally touted as a way to leverage both private (MPLS) and public (internet) networks to route traffic to the most appropriate network. Over time, SD-WAN has evolved and enabled the acceleration for more innovative services. In an effort to extend SD-WAN into a multicloud reality, SD-WAN 2.0 enhances security and analytics while connecting innovation at the edge with application and cloud concepts. While we have seen tremendous innovation in the cloud ecosystems, network and application domains are adopting similar concepts to build software-centric, programmable networks. Given these applications and networks now span clouds, data centers, WANs, LANs, and edge, the automation of networks should be viewed as a Multidomain problem. Each domain has unique challenges which should be automated locally while providing an end-to-end capability to align with the target network reality. Applications and services are becoming more distributed and require connectivity and policy enforcement across a variety of domains. Whether it is zero-trust security, intelligent network automation, Continue reading

BrandPost: Do-it-Yourself SD-WANs: No Shortage of Complexity

With interest in software-defined wide-area networks (SD-WAN) heating up, companies are facing a key question: can they implement SD-WAN themselves or do they need a service provider to help?It’s a rather loaded question, with many issues to consider if you elect to go the do-it-yourself (DIY) route. In this post, we’ll examine some of the highest hurdles you’ll have to get over if you decide to DIY; paint a picture of what sort of company may be able to tackle an SD-WAN project; and define who will be better off with a managed service.To read this article in full, please click here

BrandPost: Know the True Business Drivers for SD-WAN

If a software-defined WAN (SD-WAN) vendor calls you up and says you need their product because it will help you save money, hang up the phone. Okay, maybe you shouldn’t hang up the phone—but you should at least tell him that he’s selling his product wrong.It’s true that the early conversations about SD-WAN were all about cost savings, and those promised cost savings were to come via replacing MPLS with internet connectivity. To some extent, SD-WAN definitely delivers on this promise. That being said, saving money is not the real business driver for SD-WAN.To read this article in full, please click here

REST API 1. Basics cheat sheet (Ansible, Bash, Postman, and Python) for GET using NetBox and Docker as examples

Hello my friend,

There was a small pause with the blogposts caused by heavy load I had with the ongoing projects. However, I hope you enjoyed watching some videos I have prepared for you with the awesome guests. Today we are going to discuss some details about REST API using Digital Ocean NetBox and Docker as examples.

Brief description

The REST API was already extensively used in my previous articles about the Data Centre Fabric project such as NetBox integration with the Infrastructure Enabler Stack, monitoring of the network infrastructure using Telegraf/InfluxDB/Grafana or closed-loop automation with Kapacitor. Nevertheless, we haven’t discussed how to work with the REST API itself.

In terms of using the Web applications, there are four main action types forming CRUD abbreviation:

  • C – CREATE is an action type, which creates the entry within the application database.
  • R – READ is an action type, which extract the existing information out of the Continue reading

Network Break 243: Zoom Changes Tone On Security Vulnerabilities; Cisco Spends $2.6 Billion For Acacia

Today's Network Break analyzes Zoom's change of course on security vulnerabilities, discusses the reasons behind Cisco's multibillion acquisition of Acacia, examines IBM's closing of its Red Hat purchase, and more tech news.

The Week in Internet News: Amazon, Microsoft Look to Expand Internet Access

More access, please: Two large tech companies have announced plans to expand Internet access. First, Microsoft and Ohio-based telecom firm Watch Communications have announced an agreement to extend broadband service to underserved areas in Ohio, Indiana, and Illinois, the Associated Press reports, via the Jacksonville Journal Courier. The project is part of Microsoft’s Airband Initiative, an effort to expand service across the U.S.

Look to the sky: Secondly, Amazon has asked the U.S. Federal Communications Commission for permission to launch more than 3,200 satellites, with plans to launch a global broadband network, Smart Cities Dive says. The Amazon plan would target underserved areas across the globe as well as aircraft, ships, and submarines.

That’s a long time without service: More than 350 Internet shutdowns during the last three years have caused the equivalent of 15 years of lost access, The Telegraph reports. About two-third of those shutdowns were in India, and protests or political instability were the reasons for the government actions, according to a report from Access Now.

Warning shot: Two companies, British Airways and Marriott, are facing nine-figure fines (in U.S. dollars) under the European Union’s General Data Protection Regulation for past data breaches Continue reading

Service-defined Firewall Benchmark and Solution Architecture

Today we are happy to introduce the Service-defined Firewall Validation Benchmark report and Solution Architecture document. Firewalls and firewalling technology have come a very long way in thirty years. To understand how VMware is addressing the demands of modern application frameworks, while addressing top concerns for present day CISO’s, let’s take a brief look at the history of this technology.

 

A Brief Firewall History

Over time, the network firewall has grown up, from initially being very basic to more advanced with the inclusion of additional features and functionality. The network firewall incrementally incorporated increasingly complex functionality to address many threats in the modern security landscape.

While the network firewall initially progressed rapidly to keep pace with the development of network technology and rapid evolution of network threat vectors, over the past decade there has been very little in terms of innovation in this space. The requirements of next-generation (NGFW) haven’t changed tremendously since its late 2000’s introduction to the market, and with the uptick in adoption of modern micro-services based architectures into the modern enterprise, applications are becoming more and more distributed in nature, with growing scale and security concerns around the ephemeral nature of the infrastructure.

Micro-services, which Continue reading
