Cisco HyperFlex prepares businesses for a hybrid, multi-cloud world

It’s been a busy hyperconverged infrastructure (HCI) week for Cisco. Yesterday it announced its intent to acquire secure HCI vendor, Skyport Systems. Today it announced HyperFlex 3.0, which is the biggest update Cisco has had to the product since it introduced the product years ago. Cisco’s driving vision is a business that can run any workload on any cloud that can easily scale up as required. This latest release is entirely dedicated to fulfilling that vision.The cloud is the future, and the majority of businesses will adopt hybrid clouds. In announcing HyperFlex 3.0, Cisco cited an IDC data point that states that 87 percent of businesses are using or plan to use a hybrid environment, and 94 percent plan to use multiple clouds — meaning that hybrid, multi-clouds will be the norm.To read this article in full, please click here

IDG Contributor Network: Amadeus and intent-based analytics

In one of my favorite movies of all time, Amadeus, there is a scene in which a conversation takes place between Mozart and the Holy Roman Emperor, Joseph II, just after the first performance of the opera The Marriage of Figaro. During exchange, the Emperor “explained” to Mozart, in a condescending way, that while the opera was excellent, it had “too many notes.” He went on to suggest “Just cut a few and it will be perfect.” Nonplussed, Mozart calmly replied “Which few did you have in mind your majesty?” A pregnant pause ensues, and the Emperor is only saved by a distraction which allows the change of subject. This “change request” – while it appeared on the surface trivial to the Emperor – turned out to be quite a challenge, as it required the complete knowledge of the score (state/intent) and required composition skills (design/action). So, what does this have to do with networking?To read this article in full, please click here

It’s About Time For Time Series Databases

To get straight to the point: nobody wants to have large grain snapshots of data for any dataset that is actually comprised of a continuous stream of data points. With the data storage and stream processing now so cost-effective (relatively speaking, of course) that anybody can do it – not just national security agencies or hedge funds and brokerages with big budgets – there is pent up demand for a SQL-friendly time series database.

So that is what the founders of Timescale set out to create. And while they are by no means alone in this market, the open source …

The moving target of IoT security

As the explosive growth of IoT tech continues; businesses, vendors and consumers all have to confront the issue that the world is more connected than ever before, with potentially gigantic consequences.The central problem with IoT security is that there is no central problem – IoT is a more complicated stack than traditional IT infrastructure and is much more likely to be made up of hardware and software from different sources.+ALSO ON NETWORK WORLD: Review: VMware’s vSAN 6.6 + Configuration errors in Intel workstations being labeled a security holeTo read this article in full, please click here

BGP in EVPN-Based Data Center Fabrics

EVPN is one of the major reasons we’re seeing BGP used in small- and mid-sized data center fabrics. In theory, EVPN is just a BGP address family and shouldn’t have an impact on your BGP design. In practice, suboptimal implementations might invalidate that assumption.

I've described a few EVPN-related BGP gotchas in BGP in EVPN-Based Data Center Fabrics, a section of Using BGP in Data Center Leaf-and-Spine Fabrics article.

Alex raised a number of valid points in his comments to this blog post. While they don't fundamentally change my view on the subject, they do warrant a more nuanced description. Expect an updated version of this part of the article when I return from Cisco Live Europe

Linus Torvalds blasts Intel’s Meltdown fixes as ‘garbage’

The father of the Linux operating system has once again blasted Intel for its handling of the Spectre and Meltdown chip vulnerabilities due to the sloppiness of some of the patches. While he has a point, he’s also being a bit unfair, as well as unreasonable.Linus Torvalds is known for his blistering comments on the Linux mailing lists and frequently expresses his dissatisfaction with high levels of acidity. In this case, he was responding to an Amazon engineer on the Linux kernel mailing list regarding recent patches that have resulted in some systems randomly rebooting.To read this article in full, please click here
