Confessions of technical interviewer

A technical interviewer, or technically an interviewer. I was interviewed quite a few times since I set of to join the networking crowd, 12 years ago. I also had opportunity to sit on the opposite side, and interviewed people on multiple occasions. Some of my fondest memories of working for my current employer are connected […]

Network Virtualization at VMware Partner Exchange 2015

VMware Partner Exchange (PEX) is your one-stop shop when it comes to learning about network virtualization and the technology extends VMware’s vision of the software-defined data center. At this year’s event, we are offering both an executive track and a technical track to help partners build their businesses and advance their knowledge, as you take customers on the path to Virtualizing the Network.

If you are a partner that is new to network virtualization, we have a program/learning path where you can send two people to PEX and to achieve their network virtualization competency by attending the 3-Day NSX Install, Configure and Manage Boot Camp prior to the start of the conference. Participants can then attend the free instructor-led VSP-NV and VTSP-NV boot camps during the conference.

If you are a partner that has already achieved your network virtualization competency, and you want advanced VMware NSX technical training, there will be eight advanced technical breakout sessions throughout the conference. The advanced technical breakout sessions cover everything from “Operational Best Practices for VMware NSX” to “NSX Security Deep Dive. Logon to PEX and build your own schedule using Schedule Builder.

Knowing the technical ins and out of VMware NSX and network Continue reading

Network Programmability 101: Q&A Time

In the last video from the Network Programmability webinar Matt Oswalt answered numerous questions from the audience.

Destination Based NAT

Here is the scenario: There is a public server on the internet that you have requested access to. The “admins” that control the server agree to allow a single public IP from your entity/company to access the server. The issue arises due to the fact that you “luckily” have more than 1 Public IP at […]

Creating a Network Community for the Network’s New Operational Models

The way in which networks are configured, deployed, and managed is changing. The network industry is in a shift from managing devices box by box via the CLI to having more centralized ways to manage and deploy devices. While the CLI isn’t going away anytime soon, we can look at the two operational models that are gaining traction within the network community.

SDN Controllers

SDN controllers do two major things that increase operational efficiencies. They offer a central point of management and visibility for the network team, but also offer a single point of integration for 3rd party systems – these systems could be anything from cloud management platform, monitoring or automation systems, to native business applications. Note: even when there are controllers being used by a human, there is risk. There is the risk of clicking the wrong button, forgetting the order of operations of which buttons needs to be clicked, etc. This doesn’t go away. Change control windows still have risk.

DevOps for Networking

We’ve also seen an increased amount of focus on the intersection of DevOps and networking. I’m really referring to DevOps automation tools and the network. For example, Puppet announced $40M in funding in June Continue reading

Debunking SSD Myths

Data center, cloud, SDN driving Ethernet switch market to $25B

The Layer 2-3 Ethernet switch market is expected to exceed $25 billion in 2019, a compounded annual growth of over 2% from 2014, according to Dell’Oro Group.Data center switching will drive most of the growth in the market.  Data center switching growth will be driven exclusively by the cloud, with the enterprise market declining slowly, towards the end of the decade, Dell’Oro expects. MORE ON NETWORK WORLD: Will enhanced servers do away with the need for switches?To read this article in full or to leave a comment, please click here

Viptela brings Software-Defined WANs to the enterprise

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  In April 2014, Zeus Kerravala wrote in Network World that the software-defined WAN (SD-WAN) is now a business imperative. He cites several reasons why the time is right for companies to reconsider their WAN architecture.First of all, cloud and mobile computing, as well as applications such as video and voice over the network, are creating vastly different traffic patterns than the old style of client/server computing. Next, business agility is the enterprise mantra today, but traditional WAN architectures are too inflexible to enable the much-needed application agility. And last but not least, the complexity of the WAN makes it increasingly difficult to make even small changes in a reasonable timeframe.To read this article in full or to leave a comment, please click here

The first place to tackle SDN? In the WAN

Disruptive innovation in infrastructure is on the rise, and nowhere is that more evident than in the Software Defined Networking movement. But while much of the SDN discussion has focused on the data center, the better initial use case might be in the wide area network. One advocate of that approach is Michael Elmore, IT Senior Director of the Enterprise Network Engineering Infrastructure Group at Cigna, a global health service company headquartered in Bloomfield, Connecticut. Michael is also on the board of Open Network Users Group (ONUG). Network World Editor in Chief John Dix asked Elmore to participate in an email-based Q&A to explore the promise of Software Defined WANS.

OpenGear at Interop – Introducing the CM7100

During my all too brief visit to Interop in New York last year, I did a quick tour of the expo hall to see if there were any interesting products around. I followed Greg Ferro’s suggestion which, to paraphrase, is to seek out the booths around the edge of the show in preference to the huge booths in the middle of the floor, because the small booths around the outside are more likely to be the startups with interesting products.

Towards the end of my “small booth” tour, I bumped into some familiar faces at the Opengear booth. I first heard of OpenGear at Networking Field Day 4 where they impressed me with the flexibility of their console server products, though to call the products “console servers” rather understates some of the product capabilities which can include RPS control, TTL I/O, GPS and 3G cellular capabilities. If you haven’t seen these products before I would encourage you to look at some of my other posts about OpenGear.

New for OpenGear at Interop was their CM7100 Console Server.

There’s not a lot going on on the front panel of the device, but as you’d probably expect, the back panel Continue reading

A Deeper Look at Cisco’s SDN Certifications

It’s time to look in depth at one of the SDN certs in the market: Cisco’s Network Programmability certs. I’ve written about the emerging SDN certifications before, and will continue to update those certs as news appears. However, I’ve not yet blogged to any depth about any one certification here at SDNSkills.com. This post begins a new series that does exactly that with a deeper dive into one branch of SDN certifications: those currently offered by Cisco Systems.

Series Intro

The plan for this series is as follows: Work through some details about at least half of the 8 Cisco exams related to SDN (billed as network programmability by Cisco). I think half of them should be enough to get a sense for the whole, even if I don’t look at every single one of the eight exams. For each exam, I’ll look at the associated courses, the exam topics, take the exams, and write a summary of impressions. I’ll probably weave in and out of this topic over the coming months, hitting the first exam here in January.

SDN Market and Certifications Perspective

Some of you might already be thinking: Cisco and SDN? Isn’t SDN what Continue reading

Network Automation @Interop Vegas 2015

In case you are planning on attending Interop in Las Vegas this year, I’d like to let you know about my two sessions, both centered around emerging methodologies and technologies in the networking space.

Practical Network Automation With Ansible and Python

This is going to be a 3 hour workshop, aiming to be a practical look into network automation. I picked the topics that I have been working with most heavily in this space, and I think this workshop will be a great way to get up to speed with some down-to-earth network automation methodologies.

I am going to separate this workshop into three main parts. I’m going to start with some of the basics, and move up in “difficulty” from there.

1. YAML and Jinja2 - These are text-based specifications that allows tools like Ansible to do what they need to do. I will be making the assumption that attendees have little to no experience with either of these things, so I will spend some time exploring how these work. There’s not enough time in the workshop to be totally exhaustive, so I will only be covering the portions of either specification that are totally relevant for use with Ansible.

2. Ansible - These Continue reading
