In part 1, I’ve given an introduction to my path to learn more about Kubernetes with a hands-on approach. The story ended with Minikube being installed and a first sample application (the ‘http echosever’) up and running in a container that is managed by Kubernetes. With all of this in place now, the next logical … Continue reading Kubernetes Intro – Part 2 – The Dashboard
When we are talking about the 5G Core and implementations based on containers the story does not end with Docker containers. As a 5GC is not only based on one server and needs lots of redundancy, a management (orchestration) tool is required to manage containers across a large number of servers. There are several tools … Continue reading Kubernetes Intro – Part 1
In the previous post I’ve had a look at how I can integrate an LLM into my programming environment and use a prompt to produce and modify code, to find bugs and security issues, and to discuss options and fix issues. I find the result stunning. So is AI assisted coding a good or a … Continue reading My AI Learning Journey – Part 11 – AI Assisted Coding – Good or Bad?
I recently attended a session that focused on how to provide cloud native hardware and software in a telecoms environment today. In other words: How can network operators deploy hardware and software in their data centers to build Kubnernetes clusters, huge storage capacities and ultra fast networking that are the basis today for all kinds … Continue reading Hyperscalers at Home
I recently came across this article on Tecmint, which describes ttyd, a nifty program to make the Linux shell available remotely over the Internet. I played around with it a bit and was delighted to see ttyd can be configured to request username and password from the client and provides an https channel if you … Continue reading Shell in the Browser – ttyd – Perhaps For Online Courses?
I’m on vacation at the moment and I’ve been thinking a bit about how network technology has evolved over the past few years and where we are headed. At least for the moment, it seems to be that we have reached an access network tech plateau, at least as far as infrastructure is concerned. Let … Continue reading An Access Network Plateau Reached?
Another crazy year, both good and bad in so many ways, is coming to an end, so here I go with time honored tradition of looking back to what moved me this year in tech! In The Wireless Domain Obviously, there’s been a lot going on in the wireless domain again. While some parts of … Continue reading Things That Moved Me in 2022
When I recently read this article about vulnerabilities to break out of virtual machines, I became aware again of the concept to run virtual machines inside virtual machines. This is also called nested virtualization and it seems most modern Intel and AMD CPUs support this feature. But does it really work ‘just like that and … Continue reading Nested Virtualization
A lot of today’s services that run on servers do so in containers, either in small setups that use Docker, for example, or in Kubernetes clusters for larger deployments. By design, containers encapsulate an application, so threads in a container can’t modify anything on the host computer that is not specifically attached to the container. … Continue reading Container Vulnerabilities
It’s the time of the year again to have a look back at the things that moved me this year. On the surface, it seems that I had relatively few posts about wireless network technologies. But this appearance is quite deceptive.
