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
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
In the first part of this series, I’ve given you an overview of the services I host on my own servers to be independent of hyperscalers and to keep my data private. The number of services is stunning so there must be a lot of hardware standing around. Well, not quite so, let’s have a … Continue reading Raising the Shields – 12 Years Later – Part 2 – Hardware
In the previous post, I discussed how much data was written and read to and from the SSDs in my bare metal server in a data center over the course of a year. While this is my main server, I do have additional smaller servers at home for other purposes. One serves as redundancy for … Continue reading More on SSD Wear: My Other Servers
About a year ago, I moved one of my main bare metal servers from a datacenter in Finland to a datacenter of another provider in France. Like the old server, the current server has two 1 TB SSDs. Now that a year has passed, I was wondering how much data has been written to the … Continue reading SSD Wear On My Server: 43 TB per Year
I’m old school, I like locally attached block devices for data storage. Agreed, we are living in the age of cloud, but so far, the amount of data I store cloud at home and in data centers could always be placed on block devices, i.e. flash drives directly connected to that server. Recently, however, I’ve … Continue reading Bucket Watching – S3 at Hetzner and Scaleway
In case you seem to experience a déjà-vu right now, it is not your imagination, this is the second instantiation of this post. More about this below. But first, here we go, I’ve done it again: For the fifth time in its almost 20 year history, this blog has moved again to another physical location.
Once I had my Scaleway bare metal server up and running to my liking (see my post here), the next step in the process was to get KVM / QEMU working so I could transfer a number of virtual machines from my previous server to this equipment. One of the nice things of moving servers … Continue reading Installing KVM / QEMU on Ubuntu 24.04 and fixing the NAT
Once upon a time, not so long ago, I decided to duplicate my services running on a bare metal server at home on a bare metal server I rent in a Hetzner data center. This has worked out really well. As the server offers ample capacity, I have additionally migrated quite a number of virtual … Continue reading The Hetzner Plan C
Two years ago, I migrated a lot of my services running on virtual machines in the cloud to VMs on a bare metal server, which was also running in the cloud. The main reason: A significant cost reduction while at the same time having significantly more dedicated processing power and storage available. While I put … Continue reading Macvtap is even Cooler than I Thought
