Hetzner GEX44 with Nvidia GPU
In this technical retrospective (2024), @axelfontaine shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

FYI do not run blockchain related software on Hetzner nodes, even their dedicated bare metal. They are likely to shut the host down.
I was running a Solana Testnet Proof of Stake validator for work and they decided to shut the host down at the network layer and refused to give us access to the host. After my employer's legal threatened them, they offered to give us access back, but to be a pain in the butt, they only gave us console login access. Luckily, it was just our Testnet validator, and we keep the keys in cold storage which we were able to recover from.
Their nodes are cheap, but beware of Hetzner. Something that they didn't mind hosting for almost 4 years they suddenly changed their minds on and shut the host down.

Some lady contacted me on IG and got me to trade with this company. Constantly convincing me for one reason to the other to keep increasing my deposits. Long story short, I lost about $88,000 I've never been so disappointed in my life, trusted them only to be deceived like this. Just another one of those shady companies that have nothing to offer. Wish I had read some comments in forums earlier, wouldn't have dealt with them. Glad I found a reliable expert at Henry Walter in some forums who helped me get back everything I lost. If you're also a victim of these guys or lost your money to similar companies, write me and I'll refer you to the Recovery Experts. I'll make sure you get back everything you lost Email: davidmoore9951 (@) GM AIL , C0M
They shut down my node, because of a "billing problem". (Card was unlocked for online payments, etc.) In response, I tried in vain to pay in advance, and in response my company is now blacklisted by them. It was for a new deployment, so no harm on my side, but it's kind of comical. I didn't even get around to run any services except for a web server with almost no traffic. (It was for a simple backend service, not for public consumption.)
Kind of comical!
Despite that I wouldn't have minded using them again, but never for something which I don't have redundancy with some other provider I can fall back to. AWS can go wrong too, but I think the risk of getting booted before even starting is very low with them.
While investing in bitcoins, be cautious. If your bitcoin gets stolen, then it can be a very frustrating time but instead of getting frustrated, it is important to act fast so that you can get your money back. Unluckily, there are many victims that do not get their money back because it is very hard to track down the people behind it. The thief is either in another country or using fake identities. But in some cases, it is easy to track the person who has stolen your bitcoin. Tracing bitcoin is not hard for the bitcoin forensics or specialists.

``` RTX™ 4000 SFF Ada Generation (20GB GDDR6 ECC) 64 GB DDR4 1.92 TB (Gen4) Intel® Core™ i5-13500 30.9 TBit total bandwidth ``` I think RTX 3070 is roughly equivivalent to RTX4000 20GB.
Time used to setup and maintenance makes this valuable. Otherwise you can just buy similar system and pay for electricity.
