Four Security Myths You Need to Shake
In this zero-trust world, no data is safe. In order to tighten security in cloud-based environments, enterprises must embrace the truth about security.
Stuff The Internet Says On Scalability For April 13th, 2018
Hey, it's HighScalability time:
Bathroom tile? Grandma's needlepoint? Nope. It's a diagram of the dark web. Looks surprisingly like a tumor.
If you like this sort of Stuff then please support me on Patreon. And I'd appreciate if you would recommend my new book—Explain the Cloud Like I'm 10—to anyone who needs to understand the cloud (who doesn't?). I think they'll learn a lot, even if they're already familiar with the basics.
- $23 billion: Amazon spend on R&D in 2017; $0.04: cost to unhash your email address; $35: build your own LIDAR; 66%: links to popular sites on Twitter come from bots; 60.73%: companies report JavaScript as primary language; 11,000+: object dataset provide real objects with associated depth information; 150 years: age of the idea of privacy; 30%~ AV1's better video compression; 100s of years: rare-earth materials found underneath Japanese waters; 67%: better image compression using Generative Adversarial Networks; 1000 bit/sec: data exfiltrated from air-gapped computers through power lines using conducted emissions;

Show 385: Getting Inside Cisco Tetration (Sponsored)
If you d heard of Cisco Tetration when it was first announced, you might have a vague memory of it being this huge rack of hardware at an eye-watering price that did some sort of analytics for massive data centers.
Tetration has evolved into a platform that meets needs for organizations of many sizes. Tetration also has a bunch of genuinely interesting use cases, as Cisco has become increasingly clever about what they can do with all of that data Tetration gathers.
For example, you can auto-implement a whitelist policy for application workloads. You can detect when your apps are deviating from their normal traffic patterns. You can detect software vulnerabilities. And depending on where you run Tetration, you can still get deep network performance insights, what I think of as the original Tetration value proposition.
Today on this sponsored episode, we delve into what Tetration does, explore use cases, and dive into how it fits into compute environments. Our guests from Cisco are Jason Gmitter, Principal Systems Engineer; and Yogesh Kaushik, Senior Director of Product Management for Tetration.

Enable self-healing applications with Ansible and Dynatrace
The size, complexity and high rate of change in today’s IT environments can be overwhelming. Enabling the performance and availability of these modern microservice environments is a constant challenge for IT organizations.
One trend contributing to this rate of change is the adoption of IT automation for provisioning, configuration management and ongoing operations. For this blog, we want to highlight the repeatable and consistent outcomes allowed by IT automation, and explore what is possible when Ansible automation is extended to the application monitoring platform Dynatrace.
Thanks to Jürgen Etzlstorfer for giving us an overview of the Ansible and Dynatrace integration.

Monitoring Today
Considering the size, complexity and high rate of change in today's IT environments, traditional methods of monitoring application performance and availability are often necessary and commonplace in most operations teams. Application performance monitoring (APM) platforms are used to detect bottlenecks and problems that can impact the experience of your customers.
Monitoring alone, however, isn’t always enough to help keep your applications running at peak performance. When issues are detected, APM platforms are designed to alert the operator of the problem and its root-cause. The Ops team can then agree on a corrective action, and implement this Continue reading
Is Networking Complex/Hard ?
Its not complicated (natch). Its distributed. And we don’t have visibility to know. Distributed Systems What makes networking hard ? A network is a distributed system where state must be shared between devices that are unreliably connected. Its a fallacy that a network will ever be reliable or predictable. Skills Network technologies and their fundamentals […]
Building Bigger, Faster GPU Clusters Using NVSwitches
Nvidia launched its second-generation DGX system in March. In order to build the 2 petaflops half-precision DGX-2, Nvidia had to first design and build a new NVLink 2.0 switch chip, named NVSwitch. While Nvidia is only shipping NVSwitch as an integral component of its DGX-2 systems today, Nvidia has not precluded selling NVSwitch chips to data center equipment manufacturers.
This article will answer many of the questions we asked in our first look at the NVSwitch chip, using DGX-2 as an example architecture.
Nvidia’s NVSwitch is a two-billion transistor non-blocking switch design incorporating 18 complete NVLink 2.0 ports …

Security Research is Critical to Protect the Open Internet
On, April 10, 2018 I joined over fifty like-minded individuals signing a letter emphasizing the importance of security research. The letter renounces a number of recent lawsuits, such as Keeper v. Goodlin and River City Media v. Kromtech, against security researchers and journalists and highlights the importance of the work they are doing to defend against a rapidly increasing number of security threats.
Security research, sometimes called white-hat hacking, is a practice by ethical hackers whereby they legally find flaws in information systems and report them to the creators of those systems. The ability to find and report these vulnerabilities before other bad actors can manipulate them has become increasingly important, especially in the context of the Internet of Things (IoT).
As we discussed at Enhancing IoT Security in Ottawa, Canada this week, Internet-connected devices offer great promise, but they can also create a host of security issues. It is crucial that we continue to encourage individuals to seek out and correct flaws in these devices as their application and use grows.
As Olaf Kolkman, Chief Internet Technology Officer at the Internet Society, wrote recently, security researchers are helping to make the Internet more secure. Collaboration between those Continue reading
