Cisco continues to expand customer cloud-neutral connectivity options, this time tying its Edge Intelligence software with Amazon Web Services' IoT cloud service.Specifically, Cisco’s Edge Intelligence software now works with AWS’s IOT Core service to let customers process data from, communicate with and manage thousands of IoT devices and applications linked via industrial operations networks.Cisco Edge Intelligence runs on Cisco's IoT and industrial networking family and gathers data from connected devices to create logical flows from the edge into private, public or third-party clouds. For example, if a robotic arm in a remote system needs replacement, it can send telemetry about the problem. Edge Intelligence extracts that data and gives the operational-technology team information it can use to fix the problem.To read this article in full, please click here

The COVID-19 pandemic has influenced the networking arena in a number of ways, including the rise of fully automated remote offices, the need to support a "branch of one," and the growth of new communications software tools."One of the biggest trends we are seeing is business agility. That is, IT looking at the tech they have deployed and evaluating it not just in terms of speeds and feeds, but how agile it is to handle whatever's coming next," said Todd Nightingale, Cisco's Enterprise Networking & Cloud business chief. "Software APIs are a huge part of that trend, because it is amazingly easier to handle changes through APIs and software that make it possible to change things in a day rather than months."To read this article in full, please click here
The COVID-19 pandemic has profoundly affected many areas of IT, including the data center, where changes to the infrastructure--particularly adoption of cloud services--are bringing about the need for new skill sets among workers who staff them.

What will your worklife be like years from now? Today's work-from-home world has given us a glimpse of the future, as these five articles from CIO, Computerworld, CSO, InfoWorld, and Network World illustrate.
Deploying and operating applications in multiple public clouds is critical to many IT leaders, and networking software can help.Migrating applications to cloud infrastructure requires scale, performance, and, importantly, automation. But achieving them all can be challenging due to limited visibility into that infrastructure and the fact that each IaaS platform has proprietary controls for networking and security that can make multicloud operations highly manual and therefore time consuming.[Get regularly scheduled insights by signing up for Network World newsletters.]
As a result, IT teams can be challenged to quickly resolve application performance issues, protect against external attacks and reduce costs. Their goal should be to combine the agility of IaaS resources with the security, manageability and control of their physical network.To read this article in full, please click here
With the predicted growth in the data-center market comes a concurrent need for more staff. According to a report from the Uptime Institute, the number of staff needed to run the world's data centers will grow from around two million in 2019 to nearly 2.3 million by 2025.This estimate covers more than 230 specialist job roles for different types and sizes of data centers, with varying criticality requirements, from design through operation, and across all global regions.Already the industry is bedeviled by staffing shortages. Fifty percent of those surveyed by Uptime Institute said they were currently experiencing difficulties finding candidates for open positions, up from 38% in 2018.To read this article in full, please click here
Google Cloud Platform (GCP) is the best hyperscale performer across all areas of throughput while Microsoft Azure has the best storage systems and Amazon Web Services (AWS) has the lowest network latency.Those are the findings of a series of benchmarks performed by the atrociously named Cockroach Labs, maker of a scalable, resilient database called CockroachDB that runs on all three services. The study, part of the company’s third annual Cloud Report, evaluated the performance of AWS, Microsoft Azure, and Google Cloud in online transaction processing (OLTP) applications.In total, 54 machines were assessed and almost 1,000 benchmark runs were conducted to measure CPU, network, storage I/O, and TPC-C performance, among others.To read this article in full, please click here
User satisfaction with Wi-Fi relies in part on whether the network supports smooth handoffs between access points as users and their devices roam about, and if the APs don’t do their job well, users will complain.

Wi-Fi 6E: When it’s coming and what it’s good for
The initial tendency may be to install more APs in hopes of finding an easy fix, but doing so without careful analysis can make the situation even worse. Proper roaming requires more than just good signal strength throughout coverage areas; it takes a careful balance between the coverage of each AP on both 2.4 and 5GHz bands to make roaming work right.To read this article in full, please click here
As IP technology has matured, the range of devices that the internet protocol supports goes well beyond computers to include cell phones, entertainment systems, and Internet of Things (IoT) devices, which created the need for more IP addresses and the development of IPv6 to provide them.With more and more device types requiring network connectivity, the demand for addresses in an IPv4-based network is at a premium. It can provide somewhere south of 4,294,967,296 unique addresses. IPv6, on the other hand, can yield roughly 3.4×1038, which should be ample for a very long time.To read this article in full, please click here
Finding the best way to get from Point A to Point B is easy if you’re drawing a straight line on a piece of paper, but when Point A is your computer and Point B is a website halfway around the world, things get a bit trickier.In the latter case, Border Gateway Protocol (BGP), the routing protocol used by the global internet, is used to find the best path by weighing the latest network conditions based on reachability and routing information. BGP manages how data packets get delivered between the large networks that make up the internet and makes it possible for the internet as we know it to operate efficiently.What is Border Gateway Protocol?
BGP has been called the glue of the Internet and the postal service of the internet. One comparison likens BGP to GPS applications on mobile phones. If you were driving from Boston to Los Angeles, the GPS app decides the best route possible using existing knowledge of road conditions, traffic jams, and whether you want to travel on a toll road. Sometimes, the shortest path is not always the best path. BGP is like having a continuously updated map of the internet from Continue reading

Any time you have a text file on a Linux system that you want to keep private regardless of the privileges that other users with accounts on the system may have, you can resort to encryption. One easy way to do this is to use a feature that is built into the vim editor. You will have to provide a password that will you then need to remember or store in a password safe, but the process is straightforward. The file name will not be changed in any way, and the content of the file can be recovered in much the same way that it was encrypted.To begin, let's say that we have a file that begins like this:$ head -3 mysecret
I feel the need to put my deepest darkest secret into a text file on my Linux
system. While this likely isn't common practice, I'm not sure that I can trust
anyone with it. But a penguin? That's a different story! So here goes ...
Now, not wanting to risk your deepest darkest secret to fellow users, you use vim with its -x (encryption) option.To read this article in full, please click here
In March, IT professional association CompTIA nervously pondered what affect COVID-19 and work-from-home mandates would have on its members and its core mission of delivering training and vendor-neutral IT certifications. "When you have this kind of upheaval, what does that mean in terms of education?" says James Stanger, chief technology evangelist at CompTIA. Surely it would take a back seat to more pressing business issues. Turns out, certifications have "massively continued" their upward trend, he says.

Dan Rose, chairman of Coatue Ventures and Coatue Growth, posted a thread on Twitter the other day, 280 characters or less at a time, in which he chronicled how it came about that AWS infrastructure is built on Linux.Rose was at Amazon from 1999 to 2006, where he managed retail divisions and helped incubate the Kindle reader before moving to Facebook. So he was at Amazon in 2000 when the internet bubble popped,and one high-flying dot-com after another was shriveling up and dying, having burned through ridiculous amounts of capital on luxurious offices while often having nothing by way of a product to show for it.To read this article in full, please click here
