OpenStack Summit – Tokyo – 2015 – Thursday 29th – Show Notes

It’s Thursday, it’s 9am and…straight in to sessions. No keynote today, which is no bad thing considering these days are long!

The previous two days have consumed a huge amount of hours from sessions, keynotes and side meetings, some planned and some impromptu. This event really is the place to be if you want to speak to industry figure heads representing both vendors and consumers.

It was great to wander the market place hall, with some stands really paying attention to their interpreted understanding of the enterprises and their desire to access the OpenStack technology. This ranged from companies providing optimised tower (desktop style) servers, through to IBM showing off OCP blueprinted servers, which in turn provides a standard compute architecture. Not everyone company or organisation has a server room that wants to take advantage of OpenStack, nor do they necessarily have the skill to tie the components together. Interesting approaches all round!

Miranits, Canonical and Red Hat were present, for each tip of the consumer triangle, being: instant access, guided automation and tool-box. 


Instant AccessFuel

Mirantis offer the easy access approach, or ‘low bar’ if that’s more familiar as an ‘easy’ term. As a set of steps: Install Continue reading

Reaction: DNS versus anycast

This post raises an obvious question: are techniques using DNS to “steer” traffic (such as IP geolocation) sufficient, or do you need to consider using anycast as LinkedIn did? The short answer is that DNS steering works well and is only getting better. via circleid

Matt’s article is well worth reading, but once you’re finished reading it —

It’s well worth remembering when dealing with different load balancing solutions (like most other things in life) that the right answer is, “it depends.” In this case, do you need TCP anycast, or can you use DNS based load sharing? It depends not only on how effective each one is, but also what sort of application you’re working with. Many apps designed for smart phones don’t use DNS at all, so some form of anycast or appliance based solution are all you have. Between these two, anycast is often just as viable a solution if your network is designed to handle it correctly.

In the end, all three solutions — anycast, DNS, and appliance based — are viable options. Which one you should choose just all depends.

Juniper disaggregates even further

Juniper Networks this week unveiled a new access switch supporting 25/50G Ethernet as well as an open version of its Junos operating system for it. Juniper says it disaggregated Junos so it can enable third-party application and service support, and enhanced programmability. Disaggregation is the industry practice of breaking the dependencies of hardware and software on each other so they can be sold independently, giving customers more choice in what they purchase and operate.To read this article in full or to leave a comment, please click here

Google researchers poke holes in Galaxy S6 Edge, show OEMs add risky code

Google's security researchers hunted for bugs in Samsung's Galaxy S6 Edge phone as part of an experiment to see how vulnerable the code that manufacturers add to Android can be. It's pretty bad.The researchers found 11 vulnerabilities in Samsung's code that could be exploited to create files with system privileges, steal the user's emails, execute code in the kernel and escalate the privilege of unprivileged applications."Overall, we found a substantial number of high-severity issues, though there were some effective security measures on the device which slowed us down," the security researchers said in a blog post. "The weak areas seemed to be device drivers and media processing. We found issues very quickly in these areas through fuzzing and code review."To read this article in full or to leave a comment, please click here

SDN and NFV: The brains behind the “smart” city

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

In major metropolitan areas and smaller cities alike, governments are adopting software-defined networking (SDN) and network function virtualization (NFV) to deliver the agility and flexibility needed to support adoption of “smart” technologies that enhance the livability, workability and sustainability of their towns.

Today there are billions of devices and sensors being deployed that can automatically collect data on everything from traffic to weather, to energy usage, water consumption, carbon dioxide levels and more. Once collected, the data has to be aggregated and transported to stakeholders where it is stored, organized and analyzed to understand what’s happening and what’s likely to happen in the future.

Juniper steps up its data center game

This week, Juniper is holding its "NXTWORK 2015" customer summit in Silicon Valley. At the event, Juniper made a number of data center announcements. These announcements come about a month after Juniper rolled out its "Unite" architecture aimed at the enterprise campus (disclosure: Juniper Networks is a client of ZK Research). While the two announcements are aimed at different parts of the network, there is a common focal point, and that's helping businesses build networks that are cloud-ready. The Unite architecture was focused on simplification, whereas Juniper's play in the data center is more about customer choice and automation.To read this article in full or to leave a comment, please click here

Security made simple: RedPhone and TextSecure rolled into Signal for Android

If you want to make free, worldwide encrypted calls, then you should consider using Signal; it supports encrypted texting too.While iPhone users have had the option to use Signal since last year, yesterday Open Whisper Systems founder Moxie Marlinspike announced that TextSecure and RedPhone have been rolled into one Signal for Android app. Open Whisper Systems Signal is so super easy to use, even your granny can make private calls and send private texts. Cryptography researcher Matt Blaze previously tweeted about overhearing an elderly gentleman explaining how to install Signal; Blaze called it a “turning point.”To read this article in full or to leave a comment, please click here

How Much Is Unlimited Anyway?

unlimited-resources

The big news today came down from the Microsoft MVP Summit that OneDrive is not going to support “unlimited” cloud storage going forward. This came as a blow to folks that were hoping to store as much data as possible for the foreseeable future. The conversations have already started about how Microsoft pulled a bait-and-switch or how storage isn’t really free or unlimited. I see a lot of parallels in the networking space to this problem as well.

All The Bandwidth You Can Buy

I remember sitting in a real estate class in college talking to my professor, who was a commercial real estate agent. He told us, “The happiest day of your real estate career is the day you buy an apartment complex. The second happiest day of your career is when you sell it to the next sucker.” People are in love with the idea of charging for a service, whether it be an apartment or cloud storage and compute. They think they can raise the price every year and continue to reap the profits of ever-increasing rent. What they don’t realize is that those increases are designed to cover increased operating costs, not increased money in Continue reading

Top 3 Labs for Networkers to Get Started at Cisco’s DevNet

Today’s post gives a top 3 list: For you networkers, what are three labs to try at Cisco’s DevNet Zone, even before you have a lot of confidence with APIs?

As part of my role in the #CiscoChampion program, I wrote a recent blog post over at Cisco.com. For that post, I could pick any topic that I thought might be of interest to Cisco followers, and I ended up writing about Cisco’s DevNet Zone, Cisco’s software developer portal. I had a few more thoughts about labs beyond the other blog post, so I put those notes in this companion post. If you’re interested in Cisco’s DevNet Zone, check out both posts!
