6 Years Creating Content for You

Hello my friend,

Typically on this date, June the 5th we celebrate the birthday of our company, Karneliuk.com. It started with a blog back in 2016 and since then we are constantly creating, what we believe is, interesting and useful educational content in the area of network technologies and network automation. We thank you a lot for being with us all this time!

Technically, we started blog earlier than June the 5th, but on that date we published our first blogpost about interconnecting Cisco IOS XR and Nokia SR OS VMs, which defined the course of the blog and the direction for the company – multivendorness. We breath multivendor network technologies every day in heterogeneous networks, which our team support for our companies and customers daily. And we build multivendor network automation to unleash the true potential of networks and IT systems being an enabler for applications and user services, rather than an obstacle draining time and money of organizations.

So, what have we done in the past twelve months? Let’s take a look.

Our Own Prometheus Exporter

One of the interesting experiences we’ve obtained in the software development was the development of Prometheus exporter to report trace routes. It was quite surprisingly to find out that there was no exporter on the market which could collect traceroute information, despite Prometheus exists for quite a while already.

So, we accepted the challenge and created our own Prometheus in Python leveraging Python libraries without any nasty CLI wrappers. Moreover, we took it even further by creating a version which can run on ARM32 (e.g., Raspberry PI) platform.

Automation Open Source Tools and Pygnmi

Next important piece we’ve done is a development of various automation tools or MVPs of user scenarios, showing how Python and/or Ansible can help you to improve you network operations. The following items were very important, as they created a difference for us and helped to deliver a few projects (the list is not exhaustive, though):

Pygnmi – leading Open Source Python library for network management with gNMI. There were a few additions, which improved both a user experience and functionality. Thanks a lot to everyone, who has contributed to that.
Cumulus-5.0-api – collection of Ansible roles to manage the new generation of NVIDIA Cumulus 5.0 via REST API.
NAPALM vs OpenConfig – collection of Python scripts comparing the similarities and differences in operation between NAPALM and OpenConfig/YANG over NETCONF for multivendor network automation.
Host Connectivity Auditor – Python tool, which leverages Nornir, was created to help us auditing a customer network running mixed Cisco/Arista setup, so that we can get the list of hosts (servers) based on interfaces descriptions mapped to MAC and IP addresses.

OpenStack Series

We had a chance to be engaged in a few OpenStack projects, and I even became Certified OpenStack Administrator. Exploration of the OpenStack space showed us that it is a brilliant system; however, it is very complicated to set it up properly. Moreover, there are big promotional campaigns from all public cloud providers about their products, which also creates a big community of bloggers around them. This means that OpenStack stays quite alone and only big companies, such Ebay, PayPal or Deutsche Telecom, are using it. We decided to kick off new video series, which will give people a practical overview of what OpenStack is and how to get an OpenStack clustomer up and running relatively easy this days taking advantage of the automation tools created by OpenStack community.

New Trainings

Automation Orchestration with AWX

We created a new network automation training which aims to teach you how to use AWX (Open Source free version of Ansible Automation Controller (aka Ansible Tower)). AWX/Ansible Tower allows you to introduce an order and control in a usage of Ansible for Network an Infrastructure automation by creating a centralized execution environment, with centralized logging, Role-based access, inventory and credentials storage, and workflow managers.

Don’t miss an opportunity to upskill yourself.

New Format – Self-paced Trainings with Lab Access

We also built our own online platforms for labs, which is called Karneliuk Lab Cloud (KLC). This platform allows our students to conduct all the labs from our trainings (Zero-to-hero Network Automation Training, Network Automation with Nornir, Automation Orchestration with AWX, Closed-loop Automation and Next-generation Monitoring) in a pre-built environment, where they can focus solely on training and learning, rather than on fixing underlying infrastructure problems in Linux, what boosts the speed and quality of your study significantly.

Our Blogposts

Finally, we wrote a number of articles and recorded a few videos for you. We tried to organize them in categories; though, you may find a better way to classify them.

Thank You!

Thank you for being with us, my friend! Thanks for your questions and interactions in blog and social networks. Thanks for attending our live events and our trainings. Thanks for using out open source tools and contributing back. As Sir Elton John sings in his amazing song, “I’m still standing!” So do we.

Best wishes,
Team Karneliuk
