PlexxiPulse—Don’t Let Scalability Spook You
Last week, our director of product marketing, Bob Noel, penned a blog post that identified the five new networking requirements being driven by IoT and Big Data. This week, we are shining the spotlight on one of the third era of IT requirements Bob highlighted – scalability. In today’s dynamic application environments, the ability to scale gracefully to be able to handle distributed applications is critical. The network must be scaled to match demand, but the challenge (and a pain point for many) is how. Traditional “scale up” techniques were about replacing outgrown processing and storage capacity with bigger boxes and migrating data onto the new platform. Now, as the environment grows, more physical devices will be connected to the network. Providers need to think beyond adding capacity through bigger pipes and consider how to support a rapidly growing number of storage and compute nodes. It can be spooky thing to consider, but at Plexxi we make scaling your network to meet Third Era demands a treat, not a trick.
Below please find a few of our top picks for our favorite news articles of the week. Happy Halloween!

Book Review: ‘The Peripheral’ By William Gibson
William Gibson is working at the height of his abilities in The Peripheral. Characters move back and forth between near present-day and an unusual post-apocalyptic future, and the book blends high-tech, visionary showpieces with themes of class, opportunity, and economic injustice.

Hey, it's HighScalability time:
Movie goers Force Crashed websites with record ticket presales. Yoda commented: Do. Or do not. There is no try.
- $51.5 billion: Apple quarterly revenue; 1,481: distance in light years of a potential Dyson Sphere; $470 billion: size of insurance industry data play; 31,257: computer related documents in a scanned library; $1.2B: dollars lost to business email scams; 46 billion: pixels in largest astronomical image; 27: seconds of distraction after doing anything interesting in a car; 10 billion: transistor SPARC M7 chip; 10K: cost to get a pound in to low earth orbit; $8.2 billion: Microsoft cloud revenue;

- @jasongorman: A $trillion industry has been built on the very lucky fact that Tim Berners-Lee never thought "how do I monetise this?"
- Cade Metz: Sure, the app [WhatsApp] was simple. But it met a real need. And it could serve as a platform for building all sorts of other simple services in places where wireless bandwidth is limited but people are hungry for the sort of instant communication we take for granted here in the US.

Is DDoS Mitigation as-a-Service becoming a defacto offering for providers?
Republished from Corero DDoS Blog
It’s well known in the industry that DDoS attacks are becoming more frequent and increasingly debilitating, turning DDoS mitigation into a mission critical initiative. From the largest of carriers to small and mid-level enterprises, more and more Internet connected businesses are becoming a target of DDoS attacks. What was once a problem that only a select few dealt with is now becoming a regularly occurring burden faced by network operators.
In my daily engagements with various customers of all shapes and sizes, it’s truly interesting to see how the approach to DDoS mitigation is changing. Much of this is the result of DDoS mitigation services shifting from a “nice to have” technology to a “must-have”, essential in order to maintain business continuity and availability.
When I built DDoS mitigation and detection services for Verizon back in 2004, the intent was to offer value-add revenue producing services to offer subscribers, in an effort to build out our security offerings. For many years, this concept was one that pretty much every provider I worked with was looking into; build a service with the intent of generating new revenue opportunity from customers when traditional avenues such as Continue reading

The Threat of Telecom Sabotage
Earlier this week, an article in New York Times captured the world’s imagination with the prospect of secret Russian submarines possessing the ability to sabotage undersea communication cables (with perhaps Marko Ramius at the helm, pictured above). While it is a bit of a Hollywood scenario, it is still an interesting one to consider, although, as we’ll see, perhaps an unrealistic one, despite the temptation to exaggerate the risk.
Submarine cable cuts occur with regularity and the cable repair industry has considerable experience dealing with these incidents. However, the vast majority of these failures are the result of accidents occurring in relatively shallow water, and not due to a deliberate actor intending to maximize downtime. There is enormous capacity and resiliency among the cables crossing the Atlantic (the subject of the New York Times article), so to even make a dent, a saboteur would need to take out numerous cables in short order.
A mass telecom sabotage event involving the severing of many submarine cables (perhaps at multiple hard-to-reach deep-water locations to complicate repairs) would be profoundly disruptive to international communications — Internet or otherwise. For countries like the U.S. with extensive local hosting, the impact Continue reading

Galaxy Release 1.1.1
We’re back again with a quick update to Galaxy. In the last release we did some cool things to make searching roles much easier. This release is a mini release focused on fixing a few bugs and adding minor enhancements we couldn’t squeeze into the last cycle.
Galaxy issues are tracked publicly at https://github.com/ansible/galaxy-issues. Here are the issues addressed in release 1.1.1:
#88 Role Data Should Show Last Modified Instead of Created Date
#86 `ansible-galaxy -r roles.txt` - Incorrect Example
#84 README.md Fails to Render When it Contains a Variable String Like
#82 "Sign in" Option Should Appear on Home Page Header
#81 Better Filter for RHEL/Centos -> EL in Platform Search
#53 Adding a Role Called "Ansible" Results in Un-named Role
#14 Add Galaxy support for Debian Jessie
#9 Periods in Role Names Cause Installs to Fail
Fuzzy Searching
As part of fixing issue #81, Better Filter for RHEL/Centos -> EL in Platform Search, we changed the way the new role filtering works. A lot of times you know what you’re looking for, and don’t want to wait for autocomplete suggestions. For example, you might be looking for a Platform value of ‘centos’. Typing Continue reading
