PlexxiPulse—Powering Networks On a Global Scale

This week, we announced that Perseus selected Plexxi to deploy a next-generation network system to expand its service operations into 11 new major Asian markets and offer new services between 29 sites across the globe. By using our solutions, Perseus is able to supply low latency point-to-point and multipoint Ethernet services as well as global market data distribution in all of the world’s key emerging markets and financial liquidity centers.

Perseus came to us looking for a vendor to help improve its network’s geographic scale, simplicity, agility and service offering capabilities. Through Plexxi’s technology, the company found ways to reduce its network’s operational overhead, intense manual labor and complexity, while at the same time increasing and improving service delivery options for its customers. We’re proud that we were able to help Perseus find a solution that accommodated their requirements of today as well as those of the future. Interested in learning more about how we’re working together? Take a look at this blog post from our CEO Rich Napolitano.

The Unabomber’s brother has written a book that I can’t wait to read

David Kaczynski has lived the unimaginable: His brother Ted, the Unabomber, did more than merely kill and maim those who were victims of his attacks, he exacted a terrible toll on his own family, as is always the case with those who commit evil acts.Now David Kaczynski has written a book -- Every Last Tie – that aspires to makes some sense of an otherwise senseless situation.

Implenting Idempotency using HPE IMC

 

Try saying that five times fast.

 

What if those VLANS already exist?

There’s a concept called idempotency which can be loosely explained as

Make sure it’s like this. If it’s not like this, make it like this. If it’s already like this. Don’t do anything

Essentially, it’s a way to declare the desired configuration state of whatever it is you’re trying to configure. If the configuration state of that server, or switch or router is already in that state, than just leave it alone.

It’s a way to ensure that configuration drift doesn’t happen.

So if there’s some rabbid network administrator with a console cable running around laughing maniacly as they randomly changes things… this will help you keep them in check.

Idempotent VLANs

So we’re going to look at the last example here where we did the following:

  • grabbed the jinja template for vlans directly from a GIThub repository
  • grabbed the desired vlans file directly from a GIThub repository
  • renderd the Jinja template using the values from the vlan file to get our final config
  • used the pyhpeimc library to push the commands through the executecmd RESTful API

Worth Reading: The myth of in-memory computing

These days when you talk to people in the tech industry, you will get the idea that in-memory computing solves everything. The story is that RAM has become so cheap that you can just stuff all your data in-memory and you won’t have to worry about speed any more. But it is just a myth. Companies that buy into this myth will almost certainly regret that choice in the near future. -via the next platform

Nexusguard deploys game-changing SDN tech to mitigate large-scale DDoS attacks  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  It's easier than ever for a malicious actor to launch a DDoS attack against practically any target in the world. Groups like Lizard Squad sell DDoS-as-a-Service for only a few dollars per hour. Some attackers won’t end their attacks until a Bitcoin ransom is paid. Consequently, there are now more attacks on more organizations worldwide than ever before. Akamai recently reported a year-over-year increase of 180% in the number of attacks it saw through its network.Not only are attacks becoming more frequent, they are getting larger, too. Some recent attacks have exceeded 200 million packets per second (Mpps). An event of this size is sufficient to bring down a tier 1 router, the kind often used by Internet Service Providers (ISPs).To read this article in full or to leave a comment, please click here

FBI, keep out! How to encrypt everything

The FBI’s inability to crack a terrorist’s iPhone 5c shows the strong protection you can get for your private information on a mobile device. That same encryption is also available on your computer, at least in some cases.Given the increasing access to personal and corporate data sought by the U.S. government, as well as by other politicians, unscrupulous businesses, and criminal hackers, people should up their game on what they protect. Fortunately, it's not hard to do. (But be sure to back up your data before you encrypt your devices, in case a power failure occurs during the encryption process and makes your data unavailable.)To read this article in full or to leave a comment, please click here

Tim Cook defends Apple’s refusal to help the FBI in new interview

Apple CEO Tim Cook this week appeared on ABC News where he laid out in precise detail exactly why Apple is refusing to comply with a court order that would have the company help the FBI hack into an iPhone used by one of the San Bernardino shooters.The crux of Apple's position, as relayed by Cook, is that helping the FBI in this particular instance would only open the door to even more government requests. With such a precedent in place, Cook believes that the software tool the FBI wants Apple to develop will inevitably be used for nefarious purposes.“Once created, the technique could be used over and over again, on any number of devices," Cook explained in an open letter published last week.To read this article in full or to leave a comment, please click here
