By applying the insights of smart data, businesses can add strategic value from the cloud, while also gaining the flexibility, agility, and scalability needed to remain competitive.
2019 Is The King of Content
2018 was a year full of excitement and fun. And for me, it was a year full of writing quite a bit. Not only did keep up my writing here for my audience but I also wrote quite a few posts for GestaltIT.com. You can find a list of all the stuff I wrote right here. I took a lot of briefings from up-and-coming companies as well as talking to some other great companies and writing a couple of series about SD-WAN.
It was also a big year for the Gestalt IT Rundown. My co-host with most Rich Stroffolino (@MrAnthropology) and I had a lot of fun looking at news from enterprise IT and some other fun chipset and cryptocurrency news. And I’ve probably burned my last few bridges with Larry Ellison and Mark Zuckerberg to boot. I look forward to recording these episodes every Wednesday and I hope that some of you will join us on the Gestalt IT Facebook page at 12:30 EST as well.

So, what does that leave in store for 2019? Well, since I hate predictions on an industry scale, that means taking a look at what I Continue reading
CircleCI, Docker and Systemd
I have been battling to get the combination of CircleCI, Docker and systemd to play together. After much frustration, I have a workable solution. Machine Executor, privileged: true, cgroup passthrough, and disabling AppArmor.
Background: CircleCI for Ansible Linting & Checks
In the StackStorm team we use CircleCI with most of our repositories. We check things like code style checks, and run unit tests. With every Pull Request we trigger these checks, and checks must pass before merging. Some repos also use CircleCI for post-merge deployment steps.
We use Ansible and Terraform to manage some of our internal infrastructure. All configurations are stored in Git. All changes to that configuration must be submitted as a Pull Request. All PRs need approval, and all commit checks must pass. We use CircleCI to run these commit checks.
We run multiple checks, but for Ansible playbooks, they include using ansible-lint, and ansible-playbook --syntax-check. We then spin up a Docker container using CircleCI and run some of our playbooks twice, checking that it passes both times, and that the second run records no changes.
Here’s a snippet of some of our CircleCI configuration:

Keep Pace with Network Infrastructure Tech Changes in 2019
Here is a quick overview of the key infractructure technologies that will imapct your networks in the coming year.
NAT64Check Version 2 is launched!
With the New Year comes the launch of NAT64Check version 2 from the Internet Society. The first version of NAT64Check was introduced a couple of years ago and has proved very popular and successful, so for the past year we’ve been working on a number of enhancements in response to feedback and requests. And we’re very happy to be able to make the new version available as we welcome in 2019.
NAT64Check is a tool developed by the Internet Society in collaboration with Stichting IPv6 Nederland, Go6, SJM Steffann, Internetbureau Max and Simply Understand. This allows you to enter the URL of a particular website, and then run tests over IPv4, IPv6 and NAT64 in order to check whether the website is actually reachable in each case, whether identical web pages are returned, and whether all the resources such as images, stylesheets and scripts load correctly. It also compares responsiveness using the different protocols, therefore allowing network and system administrators to easily identify anything is ‘broken’, to pinpoint where any non-IPv6 compatible elements need to be fixed.
The original version of NAT64Check though, ran on two separate servers at Go6 and the IPv6 Lab which each had a limited view of the Internet Continue reading

7 Enterprise Infrastructure Predictions for 2019
It is no secret that enterprise infrastructures are undergoing major changes. Growing use of public cloud, SaaS, and SD-WAN in 2019 will play a significant role in the way infrastructures evolve.
Another Step Closer to Our Mission
The Internet now reaches more than half the world.
A recent estimate indicates that nearly 4 billion people – more than half the world’s population – now use the Internet. More people are now online than existed in the world the year I was born. Everyone, it seems, values the Internet. We all still know the Internet is for everyone.
The Internet Society, including all our chapters and members, was part of Internet growth in this period. 2018 was a year of many changes at the Internet Society. We changed the staff and ways of organizing work to make things clearer. We changed our CEO. But at the same time, we brought infrastructure to some of the most remote parts of the world. We pushed for better security for many of the new devices that are connecting to the Internet. And we worked to include the whole range of voices when it comes to who’s making decisions about the Internet’s future.
These are just a few of the things we, the whole Internet Society, did together. We work together because that’s what internetworking is: working together, each of us making a greater whole of our individual parts.
So, as Continue reading
Vendor Lock-in – Is It Really That Bad?!
In today’s IT infrastructure, open source software is a common component. Many organizations and network engineers stay away from certain architectures and products citing vendor lock-in as their only argument but often lack the understanding to why they think vendor lock-in is a problem. Let me explain.
There are lock-ins of different forms. For example if you are buying MPLS VPN service from a SP, you are somewhat locked in to their offering and pricing. I see at least three types of different lock-in:
Vendor lock-in – This is the one that everyone is familiar in. It means that the vendor has a solution that is proprietary, perhaps using proprietary management or routing protocols so that it can’t interact with solutions from other vendors.
Tools lock-in – This may or may not be as much of a lock-in as vendor lock-in, but when an organization has invested enough time, money and manpower into a specific toolset, it’s difficult to move to other tooling.
People lock-in – An often oversighted form of lock-in. Depending on architecture, toolset and so on, your organization may need a certain type of engineers to work on the network. These may be difficult to find which Continue reading

IPv6 in China
China has an estimated Internet user population of 741 million, out of a total population of 1.4 billion people. If there was extensive deployment of IPv6 services in China, then the case that IPv6 has already achieved critical mass of deployment would be easy to make. On the other hand, if such a significant user population had no IPv6 service and no visible plans for IPv6 services, then the entire conversation about the times and certainties about the future of IPv6 takes on a different direction. Which means that China matters in the world of IPv6. It matters a lot.My Ignorance for a Year and Dell IDRAC
Hi,
I have a Dell R810 and it makes a lot of noise. So, I have put it somewhere remote in the home where it’s completely inhabitable for human beings. Now, the problem was always to go there and manually power-up the system. This has been the scenario for years. So, technically if am away from my home I need to take help from my wife. All this is going well and I was always wondered should it not have a better way to do things.
Was talking to my friend and he had some paid solution for the same thing, he doesn’t even remember and that’s for his cisco gear, now for Cisco gear as long you supply power they will be powered (if the Power button is always on), for servers however just like our Personal CPU’s and Laptops you have to manually press the power button.
Then yesterday all of a sudden I took this somewhat seriously and explored options, then I understood it was sitting right inside the server, Dell has something called Integrated DRAC system which helps you do this thing, all you need to have is a proper Lan connection, the message was Continue reading
