Got my number!

After a week of waiting (why this is taking so long? this wasn’t a particularly pleasant week), I finally got my number.

Brand new JNCIE-DC #31 !!!

The main note about the lab – time management is the most important thing on the exam. Don’t rush to the keyboard, read and understand all the tasks and it’s interdependencies. Have a plan regarding order of tasks – not all tasks can be completed in order in which they written. Don’t be affraid to skip some tasks if it takes a long time.

I am quite pleased with the level of my preparation for the lab – there were no unexpected or incomprehensible tasks. General feeling about JNCIE-DC lab – this is interesting, pretty complex but fair exam. Lot of tasks on various themes, I think all themes from blueprint are covered in the lab in some ways.

As the proctor told me, the main difficulty of this exam is that it’s something new, and people are afraid of a new and unexpected. I want to tell you – don’t be afraid! If you’re interested in learning a Juniper way of building Data Center networks, and also want to earn one more pretty Continue reading

Worth Reading: Supporting new DNS RR types

The Domain Name System has always been intended to be extensible. The original spec in the 1980s had about a dozen resource record types (RRTYPEs), and since then people have invented many more so now there are about 65 different RRTYPEs. But if you look at most DNS zones, you’ll only see a handful of types, NS, A, AAAA, MX, TXT, and maybe SRV. Why? A lot of the other types are arcane or obsolete, but there are plenty that are useful. Moreover, new designs like DKIM, DMARC, and notoriously SPF have reused TXT records rather than defining new types of their own. Why? It’s the provisioning crudware. —John Levine @ CircleID

Automating Documentation

Tedium is the enemy of productivity. The fastest way for a task to not be done is to make it long, boring, and somewhat complicated. People who feel that something is tedious or repetitive are the ones more likely to marginalize a task. And I think I speak for the entire industry when I say that there is no task more tedious and boring than documentation. So how can we fix it?

Tell Me What You Did

I’m not a huge fan of documentation. When I decide on a plan of action, I rarely write it down step-by-step unless I’m trying to train someone. Even then, it looks more like notes with keywords instead of a narrative to follow. It’s a habit that has been borne out of years of firefighting in networks and calls to “do it faster”. The essential items of a task are refined and reduced until all that remains is the work and none of the ancillary items, like documentation.

Based on my previous life as a network engineer, I can honestly say that I’m not alone in this either. My old company made lots of money doing network discovery engagements. Sometimes these came because the Continue reading

Microsoft acquires cloud-based HPC developer

Microsoft pulled off a big get with its acquisition of Cycle Computing, the developer of a suite of high-performance computing (HPC) services called CycleCloud for cloud orchestration, provisioning and data management in the cloud.You may not know its name but Cycle Computing is actually a major player. In 2012, it helped Amazon create the first massive cloud-based supercomputer, spanning 51,000 cores. For just one hour of run time, the bill was $5,000.+ Also on Network World: Azure Stack: Microsoft’s private-cloud platform and what IT pros need to know about it + In 2013, Cycle Computing hit its biggest cloud run, creating a cluster of 156,314 cores with a theoretical peak speed of 1.21 petaflops that ran for 18 hours and spanned Amazon data centers around the world. The bill for that monstrosity was $33,000. To read this article in full or to leave a comment, please click here

Feedback: Network Automation 101

Some networking practitioners start their network automation journey with the Python or Ansible dilemma. Engineers and architects usually want to understand the bigger picture first, and figure out the potential showstoppers and roadblocks. One of them left this feedback on the Network Automation 101 webinar:

A must-have overview of fundamental Network Automation concepts. I wouldn't face an automation project without understanding these concepts first.
