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

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

Cisco acquires Skyport Systems to bolster its hybrid cloud positioning

For today’s IT professional, hybrid clouds are a fact of life and will be for years to come. Digital businesses need to have an agile infrastructure foundation, which the cloud provides.However, rarely does one size fit all when it comes to cloud options. Some workloads are ideally suited for public cloud services, while others make more sense to go in a private cloud. With some apps, though, part of it runs in the traditional data center and part runs in a public cloud, such as Amazon Web Services (AWS), Microsoft Azure or Google Cloud Platform. There are also apps that run in a private data center but then need to connect to a SaaS application.To read this article in full, please click here
