After exploring many new technical topics over the past few months, including Docker and Kubernetes, I ventured out over the weekend to have a look at OpenStack. I wanted to have a closer look because OpenStack is used to provide a private cloud infrastructure, i.e. virtual machines (compute), storage, and networking for many projects. OpenStack … Continue reading Playing with OpenStack – A Rather Unpleasant Experience
Over the past months, I’ve been experimenting a lot with Docker and Kubernetes and decided to pass on the knowledge I have gained in occasional cloud-based hands-on workshops rather than doing presentations or videos. The advantage: Instead of talking ‘against a wall’ with virtually no feedback whatsoever during and after a presentation, hands-on workshops are … Continue reading A Firewall for Online Workshops
In the previous post on the topic I wrote about the three eras of telecom infrastructure hardware. As we are now entering the third area, there are not only whitepapers written about how everything from the radio network to the mobile core can be but into containers, but there are also demo videos of such … Continue reading An ‘Everything in Containers’ LTE and 5G Demo
As you might have noticed on the blog, I’ve been doing a lot of hands-on exploration these days of bare metal hardware, virtual machines, containers and orchestration (e.g. Kubernetes). My motivation behind this is twofold. For one thing, I like to evolve my private cloud. Current status: 25 containers are now running in my private … Continue reading The Three Eras Of Telecom Infrastructure Hardware
After the six ‘Dockerize Me‘ and four ‘Kubernetes Intro‘ episodes that mainly dealt with getting a good understanding of how to use containers, the time has come for me to deal with the ‘end boss‘ of the game: Dockerizing the web-based database system I’ve been working on in my quality time over the years. I … Continue reading App To Docker – Part 1 – Volume Magic
Last year I wrote about a 5G Americas whitepaper that describes how 3GPP has standardized the 5G core in a way that lends itself for cloud based implementation. In short, that means that control plane functions are split into microservices, deployed on bare metal clusters in containers and managed with Kubernetes. So far the theory. … Continue reading The Cloud Based 5GC – From Theory To Practice
Over the years I’ve been looking at Docker every now and then. That’s because for one thing I am interested in the concept of deploying software in lightweight containers instead of VMs and also because I am running two pieces of software in Docker containers on my servers as well. But that was it until … Continue reading Dockerize Me – My Personal Docker Bootstrap Voyage – Part 1
When you look through the 5G core network specification documents of 3GPP such as TS 23.501 and 23.502 the idea I got was that it’s pretty much the same as before. Yes, the interfaces and network components have new names but by and large the 5G core network does the same things as today’s core … Continue reading The Cloud Native 5G Core Network
