Wireless alliance: You might want to move some access points for Wi-Fi 6

Businesses could find themselves repositioning wireless access points and even facing increased bandwidth demands as Wi-Fi 6 hits the market in the coming months, according to a white paper released today by the Wireless Broadband Alliance.Nevertheless, the news is mostly good for prospective business users. Thanks to Wi-Fi 6’s array of coexistence, power-saving and smart management features, a new network based on the technology shouldn’t pose many deployment problems.The time of 5G is almost here Key to the enterprise WLAN use case, the white paper says, is deployment planning – Wi-Fi 6 can offer different optimal placement options than previous-generation Wi-Fi, so it could behoove upgraders to consider changing AP locations, instead of just swapping out existing devices in the same locations.To read this article in full, please click here

Three key checklists and remedies for trustworthy analysis of online controlled experiments at scale

Three key checklists and remedies for trustworthy analysis of online controlled experiments at scale Fabijan et al., ICSE 2019

Last time out we looked at machine learning at Microsoft, where we learned among other things that using an online controlled experiment (OCE) approach to rolling out changes to ML-centric software is important. Prior to that we learned in ‘Automating chaos experiments in production’ of the similarities between running a chaos experiment and many other online controlled experiments. And going further back on The Morning Paper we looked at a model for evolving online controlled experiment capabilities within an organisation. Today’s paper choice builds on that by distilling wisdom collected from Microsoft, Airbnb, Snap, Skyscanner, Outreach.io, Intuit, Netflix, and Booking.com into a series of checklists that you can use as a basis for your own processes.

Online Controlled Experiments (OCEs) are becoming a standard operating procedure in data-driven software companies. When executed and analyzed correctly, OCEs deliver many benefits…

The challenge with OCEs though, as we’ve seen before, is that they’re really tricky to get right. When the output of those experiments is guiding product direction, that can be a problem.

Despite their great power Continue reading

Heavy Networking 458: SDN Federation – One Controller To Rule Them All?

You might have any number of software controllers in your infrastructure: one for wireless, one for SD-WAN, one in the data center, one for security, and so on. Would it be useful to federate these controllers? Can we expect the industry to produce a controller of controllers? Is this even a good idea? Today's Heavy Networking podcast ponders these questions with guest Rob Sherwood.

IBM closes $34B Red Hat deal, vaults into multi-cloud

IBM has finalized its $34 billion purchase of Red Hat and says it will use the Linux powerhouse's open-source know-how to enable larger scale customer projects and to create a web of partnerships to simplify carrying them out."A lot of our mutual clients are interested in doing a lot more," says Arvind Krishna, Senior Vice President, IBM Cloud & Cognitive Software in a blog post. "Many see this as an opportunity for us to create large industry ecosystems with other providers who are optimized on this common infrastructure. ...If Red Hat were to do this on their own, there would be a limit to how much they can scale. Together, we can put a lot more resources into optimizing other partners."To read this article in full, please click here

Linux a key player in the edge computing revolution

In the past few years, edge computing has been revolutionizing how some very familiar services are provided to individuals like you and me, as well as how services are managed within major industries. Try to get your arms around what edge computing is today, and you might just discover that your arms aren’t nearly as long or as flexible as you’d imagined. And Linux is playing a major role in this ever-expanding edge.One reason why edge computing defies easy definition is that it takes many different forms. As Jaromir Coufal, principal product manager at Red Hat, recently pointed out to me, there is no single edge. Instead, there are lots of edges – depending on what compute features are needed. He suggests that we can think of the edge as something of a continuum of capabilities with the problem being resolved determining where along that particular continuum any edge solution will rest.To read this article in full, please click here

Cisco goes deeper into photonic, optical technology with $2.6B Acacia buy

Looking to bulk-up its optical systems portfolio, Cisco says it intends to buy Acacia Communications for approximately $2.6 billion.  The deal is Cisco’s largest since it laid out $3.7B for AppDynamics in 2017.Acacia develops, manufactures and sells high-speed coherent optical interconnect products that are designed to transform networks linking data centers, cloud and service providers. Cisco is familiar with Acacia as it has been a “significant” customer of the optical firm for about five years, Cisco said.To read this article in full, please click here

Internet Society’s Online Trust Alliance 2018 Cyber Incidents & Breach Trends Report

On Tuesday July 9, 2019 the Internet Society’s Online Trust Alliance (OTA) released its 11th Cyber Incident & Breach Trends report, which provides an overview of cyber incidents – and offers steps organizations can take to prevent and mitigate the potential damage. This year’s report found a shifting landscape of cyber incidents. As the growth of some attack types levels off, others increase.

Adding it all up, OTA estimates that there were more than 2 million cyber incidents in 2018, and it is likely that even this number significantly underestimates the actual problem. OTA estimates an overall financial impact of at least $45 billion worldwide. The lead categories of attacks are cryptojacking (1.3 million) and ransomware (500,000), followed by breaches (60,000), supply chain (at least 60,000 infected websites), and Business Email Compromise (20,000).

There are many organizations that track data breaches overall. For example, Risk Based Security Reported the highest number at 6,515 breaches and 5 billion exposed records, both down from 2017. These estimates vary depending on their methodologies – see our full report for all of the breach estimates and our methodology.

One well-established attack type, ransomware, saw a decline in 2018. However, the total dollar Continue reading

BrandPost: Improving IT Operations – Key to Business Success in Digital Transformation

Forty seven percent of CEOs say they are being “challenged” by their board of directors to show progress in shifting toward a digital business model according to the Gartner 2018 CIO Agenda Industry Insights Report. By improving IT operations, organizations can progress and even accelerate their digital transformation initiatives efficiently and successfully. The biggest barrier to success is that IT currently spends around 78 percent of their budget and 80 percent of their time just maintaining IT operations, leaving little time and resource left for innovation according to ZK Research*.To read this article in full, please click here

Colocation facilities buck the cloud-data-center trend

Data center workloads are moving but not only to the cloud. Increasingly, they are shifting to colocation facilities as an alternative to privately owned data centers.What is colocation? A colocation facility or colo is a data center in which a business can rent space for servers and other computing hardware that they purchase but that the colo provider manages.Read about IPv6 and cloud-access security brokers The colo company provides the building, cooling, power, bandwidth and physical security. Space is leased by the rack, cabinet, cage or room. Many colos started out as managed services and continue  to offer those specialized services.To read this article in full, please click here
