- Comment on Microsoft getting nervous about Europe's tech independence 1 day ago:
There is no one answer that fits all. Where cloud will always be cheaper is data storage.
If you were to host everything on-prem, that would be a lot of capex. It would cost to maintain that as well. For on-prem, you have to think more about electricity, redundancy, backups, security, and so on. Anything you would need to do to build out a data center. Once you have it set up though, yes it would be cheaper.
For tech companies, this is already a non starter as they want to scale and scale fast. They also can’t just spend all their investors money, so they convert capex into opex instead.
Also, historically, IT is slow. Very slow. This is why there is a world of DevOps because developers became increasingly frustrated with how slow it is to provision infrastructure for them. To fix this, you could probably hire more people, but again, that’s an extra expensive that you can just now offset to cloud.
With cloud you can set up something in multiple data centers within minutes. If on-prem, you would need to have multiple physical locations of your own.
Another option is to rent out space in a data center, then you just buy your own hardware and do not have to worry about 80% of what would go into a data center. You would still need to set up these systems in a way that can scale for future use, which means more capex up front.
At the end of the day, there is no one size fits all. As you mentioned, most businesses could benefit in the long run by hosting their own stuff. I will say though, managing things like your own email server has become a nightmare. This is just a lot easier to let someone else manage. Then again, you have the concern of data storage, this is just easier and cheaper to host in cloud. Something like Google workspace or m365.
To put it another way, go to your boss and tell him you need to pay $2,000,000 up front for IT hardware. Now tell him you’ll need to pay $250,000 a year for the same thing services in cloud. What do you think they will go with?
I do hate that it’s come to this though, because I feel like people are losing knowledge. Only the people that build data centers these days will have that IT knowledge and you have people that can no longer tinker like we used to.

I have a loan right now that is at like 3%. I can pay it off now if I wanted to, but it’s so low that I can easily make more money by putting it away and collect interest on it. It would be kinda nice to get a new car, but where this country is headed, it’s not worth it. I feel bad for the younger generations and what lies ahead for them.

LLMs are smart, they are just not intelligent
- Comment on What host names do you use? 1 month ago:
I have to ask, why start with 0? I never understood this with infrastructure. I would do something like 00000 if I did numbers so it would be easy to sort, but I always started with 1. I’m just curious.
- Comment on Self-hosted home server project - call for competent advisory opinions 2 months ago:
You will get different answers. Some people like proxmox with ZFS. You can run vms and lxc containers pretty easily. Some people like running everything in a container and using podman or docker. Some people like to raw dog it and just install everything on bare metal ( I don’t recommend this approach though).
The setup I currently have are 3 servers. One server for compute. This is where I run all my services from. 1 server for storage. 1 server for backup storage.
The compute server is set up with an NFS share that connects to the storage server. These all have a 10gbe nic on a 10gbe switch.
If I could go back and redo this setup again, I would make a few changes. I do have a few NVMe drives in my storage server for the NFS share. The compute server has the user home directories on there, as well as the permanent files for the containers that have volumes. This makes it easy for me to backup that data to the other server as well.
With that said, I kinda wish I went with less storage and built out a server using mostly nvmes. My mobo doesn’t do bifurcation on its x16 slots and so I can only get 1 NVMe per slot. It’s a waste. Nvmes can run somewhat hot, but are smaller and easier to cool than platters. Plus it’s faster to rebuild if something were to happen. You could probably get away with using 1 parity drive because of this.
I would still need a few big drives for my media, but that data is not as critical to me in the event I lost something there.
What I would look for in a storage system are the following:
- mobo with rdimm memory
- bifurcation pcie slots to add adapter cards for NVMe drives or lots of NVMe slots on the mobo.
- if doing 10gbe, use sfp+ nics and a sfp+ switch (runs cooler). Then you would just get sfp cables instead of cat6/6e.
- management port (ipmi)
- as much memory as you can afford
With those requirements in mind, something like an ASRock server motherboard using an AMD epyc would normally fit the bill. I have seen bundles go for about 600-700 on AliExpress.
As far as the OS. I treat the storage server as an appliance. I have truenas on there. This is also the reason I have a separate computer server as it makes it easier for me to manage services the way I want, without trying to hack the truenas box. This makes it easy to replicate to my backup since that is also truenas. I have snapshots every hour and those get backed up. I also have cloud backup for critical data every hour.
Last, but not least, I have a vps server so I can access my services from the internet. This uses a wireguard tunnel and forwards from the vps to the compute server.
For the compute server, I am managing mostly everything with saltbox. Which uses ansible and docker containers for most services.
No matter what you choose, I highly recommend ZFS for your data. Good luck!
- Comment on What do people use for a shelf-stable backup 2 months ago:
That sounds like a really good idea. You basically get the best of everything.
The cool thing about ZFS is the pool information is stored on the disks themselves. You can just plug them in and import the pools.
- Comment on What do people use for a shelf-stable backup 2 months ago:
I decided instead to use ZFS. Better protection than. Just letting something sit there. Your backups are only as good as your restores. So, if you are not testing your restores, those backups may be useless anyway.
ZFS with snapshots, replicated to another ZFS box. The replicated data also stores the snapshots and they are read-only. I have snapshots running every hour.
I have full confidence that my data is safe and recoverable.
