It was a little over a year ago, that I sat back in my theoretical chair at my cushy enterprise job and started thinking about what was next. There was a good amount of change and velocity in the role that kept me satisfied for the past six years, but there was also a growing […]
LogicMonitor, which sells a SaaS platform to monitor IT infrastructure and public cloud performance, has launched new offerings for Kubernetes and a service-oriented view of infrastructure components.
Transitioning from MPLS to SD-WAN is a big move. It’s important to remember, however, that even the most dramatic transition requires that attention be paid to small and mundane details. Not doing so can cost time and money — and not a small amount of either. I speak to a lot of companies. One of […]
The repercussions of the CenturyLink outage are still being felt weeks after the provider announced the problem solved. Even the FCC has gotten involved, announcing an investigation into what happened (see our blog on SD-WAN-Experts for more details). For enterprise IT, the outage certainly should give pause for anyone considering CenturyLink’s backbone as part of […]
If you’ve been in IT for more than a few minutes you been here before. Widget X is burning, the organization is hemorrhaging cash, and we’re all doomed unless some caped infrastructure superhero swoops in to save the day. You’re just the hero for the job, but what are you going to do? I’m going […]

Huawei is likely a serious risk but not for the reasons that you think.
As a member of vExpert community – I had a very unique opportunity and honor to present at vBrownBags spot during Re:Invent 2018 – the video of my presentation is available at YouTube Below is the content of my thoughts around my quest into the new reality of Software Defined everything. 10-15 years ago System and […]
Continued from Part 1 Fat Tree Fat-Trees were originally introduced by Charles Leiserson in 1985. The basic idea behind fat-trees is to alleviate the bandwidth bottleneck closer to the root with additional links. Below is a logical representation of a 4 level Fat-Tree, you can see how the link capacity grows towards the root. A […]
Apstra has announced root cause identification and other new features in the latest version of its intent-based networking (IBN) software, but IBN has hurdles to get over before its utopian vision of the data center can come to fruition.
Fresh from a conference of MPLS providers telling people that only MPLS or Direct Internet Access (over MPLS) is the only possible solution. Its not, SDWAN over 4G works and often is cost effective too. MPLS is expensive and often more expensive than 3G/4G. An SDWAN solution makes a good network out of any bandwidth. […]
In this post, I will be focusing on a topic related to Datacenter domain which is an area I haven’t focused in the past. But since I find Topologies as an interesting area, it created enough motivation for me to write this post. So I know that nowadays the most widely adopted topology for the datacenter fabrics […]
It’s no secret that relations between Amazon and Oracle are very sour. Oracle has made very public claims that critical Amazon run on their databases. This was done without permission (a legal requirement to use another brand as an endorsement) and against Amazon’s no brand sharing policy. James Hamilton writes on his personal blog: However, […]
Nearly two years ago, I opined that supplier management might be the biggest threat to SD-WAN adoption. My argument was that SD-WAN required enterprises to equip locations with multiple Internet connections (assuming they were eliminating MPLS), ideally from different ISPs, if they’re to match MPLS uptime. All of which means that any IT team considering […]
LiveAction’s 8.0 version of its LiveNX network performance management software now integrates with packet capture hardware and protocol analyzer software from Savvius, which LiveAction acquired in June 2018.
Enterprise IT used to be dominated by one supplier in each market (think Cisco in switching, Microsoft in desktops, etc.). Will the same pattern repeat in a “software-defined” world, or will diversity reign?
Earlier this month, Extreme Networks rolled out a whopping big announcement that included upgrades to its management, analytics, and automation software, as well as new hardware. On the software side, Extreme upgraded its management and monitoring software, Extreme Management Center, to encompass data center operations in addition to existing campus and edge management capabilities. The […]
I’ve been using ‘Reader Mode’ on MacOS Safari browser for quite some time. With the new dark mode feature, it a much better way to get information into my weary brain. Maybe it can work for you too.
A few years ago I was using Cisco VIRL fairly extensively to lab some changes in my production environment. I had to keep VIRL environment completely isolated from the rest of my network, which meant that I had only console access via telnet to configure the devices. I wished I could use Ansible, but it […]
Teridion has announced a virtual network service to compete with MPLS providers. Its overlay combines IPSect tunnels, monitoring, and performance-based routing to meet customer service levels, and it’s partnering with SD-WAN vendors to go to market.
Back in the summer of 2017, my book ‘Mastering Python Networking‘ by Packt Publishing was released, fulfilling a life-long goal of mine to become a published author (if you are interested in the background, content, and thoughts behind the book, you can check out Packet Pusher Priority Queue 135). It’s been an unbelievable ride since […]
Cisco Systems has announced its first-ever 400GbE switches. Expected to ship in the first half of 2019, these switches target hyperscaler companies, cloud and service providers, and large enterprises.
Companies don’t care about you. It’s up to you have a plan B for your career if plan A goes off the rails.
In October 2018, I heard a presentation from Cisco about the future of ACI. The presentation was entitled “ACI Anywhere.” The idea was to talk through how Cisco is expanding ACI’s footprint from the data center to other locations, including the cloud. The Cloud APIC was the most interesting part of the ACI Anywhere vision […]
IT Security costs too much, paying fines is much cheaper
