Nonlinear Effects of Optimization-Induced Complexity

We have school holidays this week, so I’m reposting wonderful comments that would otherwise be lost somewhere in the page margins. Today: Minh Ha on recent Facebook failure and overly complex systems (slightly edited).

---

I incidentally commented on your NSF post some 3 weeks before […the Facebook outage…] happened, on the unpredictable nature of nonlinear effects resulting from optimization-induced complexity. Their outage just drives home the point that optimization is a dumb process and leads to combinations of circular dependency that no one can account for and test.

On DNS Openness

How open is the DNS market? This is q question that is not just about barriers to competitive entry for new providers into the market. There is more to this question about the use of markets as a signalling mechanism across a diverse collection of intertwined producers and consumers. How effective is the market as a signalling mechanism across these entities? Is the market providing clear signals that allows orchestration of activity to support the evolution of a coherent and robust service? Is the market-driven evolution of the delivered product or service one that is chaotic and periodically disrupted?

BrandPost: Connectivity Shouldn’t Limit Industry 4.0 Acceleration

When the coronavirus pandemic forced shutdowns across the world, industries faced a disaster unlike ever before. Facilities and IT systems were operational, yet people could not physically access them. According to a 2021 McKinsey survey, Industry 4.0 technologies were a lifesaver, with 94% of respondents saying they helped keep operations running and more than half (56%) reporting they were critical to doing so.COVID-19 put Industry 4.0 and digital transformation into third gear, while preparing enterprises for the post-pandemic era. However, these technologies depend on connectivity, and legacy solutions such as wired connections or WiFi are not up to the challenge. To read this article in full, please click here

Peek Under the Hood: SE Labs NDR Test 

Earlier this month, SE Labs awarded VMware the first ever AAA rating for Network Detection and Response (NDR)–highlighted by our ability to provide 100 percent protection from four major advanced and persistent (APT) groups across multi-cloud environments. The NDR test, the first of its kind, signified the changing threat landscape where enterprises need to identify and stop attackers inside the network where they are able to move freely to discover valuable information they can exfiltrate. Given expanding threat surfaces due to modern applications, work from anywhere and cloud transformation, the assumption is that attackers are likely already inside your network, making legacy cybersecurity tests focused solely on the perimeter increasingly-unsuitable assessments for protecting today’s modern enterprise. 

According to the results from SE Labs, VMware NSX NDR provides 100 percent protection across multi-cloud environments from four major advanced and persistent threats (APT) groups—including FIN7&Carbanak, OilRig, APT3 and APT29—while returning zero false positives. This ability allows security operations teams to rapidly detect malicious activity and stop the lateral movement of threats inside the network. 

Given that this is the first test of its kind, we wanted to give you a look under the hood to see how SE Labs used VMware NDR to detect all malicious network traffic and payloads from a specific threat group—OilRig – APT 34. Check out the Continue reading

NetApp overhauls cloud storage lineup

NetApp used its virtual NetApp Insight 2021 conference as the launchpad for several new technologies and enhancements to existing products, as well as to announce an acquisition. All are meant to bolster the on-prem storage supplier’s cloud offerings.First up, NetApp introduced ONTAP 9.10 Enterprise Data Management software, which includes upgrades that protect against ransomware and enhanced detection and recovery capabilities. The new software also features expanded data management capabilities and NVMe/TCP support.NVMe traditionally works over a network fabric, but there are bottlenecks – namely, you have to build the fabric. NVMe/TCP allows the same storage devices to be shared among data centers through the Internet protocol over the existing network.To read this article in full, please click here

Big Picture: BFD, Non-Stop Forwarding, and Graceful Restart

We have school holidays this week, so I’m reposting wonderful comments that would otherwise be lost somewhere in the page margins. Today: Erik Auerswald’s excellent summary of BFD, NSF, and GR.

---

I’d suggest to step back a bit and consider the bigger picture: What is BFD good for? What is GR/NSF/NSR/SSO good for?

BFD and GR/NSF/NSR/SSO have different goals: one enables quick fail over, the other prevents fail over. Combining both promises to be interesting.

Startup gives IT control of GPU pools to maximize their use

Among the greatest component shortages bedeviling everyone is that of GPUs, both from Nvidia and AMD. GPUs are used in Bitcoin farming, and with massive farms around the world gobbling up every GPU card, getting one is nigh impossible or prohibitively expense.So customers need to squeeze every last cycle out of the GPUs they have in service. An Israeli company called Run:AI claims it has a fix with a pair of technologies that pool GPU resources and maximize their use.The technologies are called Thin GPU Provisioning and Job Swapping. Not the most creative of names but they describe what the two do in tandem to automate the allocation and utilization of GPUs.To read this article in full, please click here

The New Normal is Insecure by Default

Organizations are tacitly agreeing to accept greater risk by moving quickly without equal attention to security. The new normal we heard so much about throughout the pandemic is apparently “insecure by default.”

Master Class: Resilience in Large-Scale Fabrics

In the aftermath of a major network outage, the natural reaction of most network engineers is to find some way to avoid all future outages—regardless of the cost. The first line of defense against is future outages is redundancy, whether in the form of additional parallel links, new routers, new firewalls, new … whatever, so long as there is more of it so packets have more paths to make it from source to destination.
