As far as I see, no one is mentioning sustainability AKA environmental impact or 'green hosting' here. Don't you care about that? I believe that Hetzner data centers in Europe (Germany, Finland) are powered by green energy, but not the locations in US.

Data centers used 460 TWh, or about 2% of total worldwide electricity use, according to IEA in 2022. In comparison, 30% of total energy (energy! Not electricity) goes to transport! As another point of comparison, transport in Sweden in 2022 used 137 TWh [1]. So the same order of magnitude as total datacenter energy use. And datacenters are powered by electricity which increases the chance that it comes from renewable…

2% of total worldwide electricity use in 2022 is a shit load of electricity and emissions. Your argument is the same as those who argue "our country shouldn't care about emissions when China is the biggest emitter".

If you dive into a detailed breakdown of emissions you'll find that it's a complex hierarchy of categories. You can't just fix "all of transport" or treat it like a "low hanging fruit", just look at how much time it's taken for EV penetration to be in any way significant; look at how much of transport emissions are from aviation or shipping or other components.

Any energy use that's measurable in whole percentage points of global emissions needs addressing. That includes data centers.

When I worked in web hosting (more than 10 years ago), we would constantly be blackholeing Hetzner IPs due to bad behavior. Same with every other budget/cheap vm provider. For us, it had nothing to do with geo databases, just behavior. You get what you pay for, and all that.

It's always evolving, but these days the most common platforms attacking sites that I host are the big cloud providers, especially Azure. But AWS, Google, Digital Ocean, Linode, Contabo, etc all host a lot of attacks trying to brute-force logins and search for common exploits.

Been a happy Hetzner customer for over a decade, previously using their dedicated servers in their German DC's before migrating to their Cloud US VMs for better latency with the US. Slightly disappointed with their recent cuts of their generous 20TB free traffic down to 3TB (€1.19 per additional TB), but they still look to be a lot better value than all other US cloud providers we've evaluated. Whilst I wouldn't run…

Seems to be a US thing, maybe their peering partners are forcing them to raise prices, the German DC still stells the 20TB bandwidth https://www.hetzner.com/cloud/, but US is an order of magnitude less for the same price :/

We're very happy to use Hetzner for our bare-metal staging environments to validate functionality, but I still feel reluctant to put our production there. Disks don't quite work as intended at all times and our vSwitch setup has gotten reset more than once.

All of this makes sense considering the extremely low price.

I have experience running Kubernetes clusters on Hetzner dedicated servers, as well as working with a range of fully or highly managed services like Aurora, S3, and ECS Fargate. From my experience, the cloud bill on Hetzner can sometimes be as low as 20% of an equivalent AWS bill. However, this cost advantage comes with significant trade-offs. On Kubernetes with Hetzner, we managed a Ceph cluster using NVMe storage,…

Manually updating k8s clusters is a huge tradeoff. I can’t imagine doing that to save a couple bucks unless I was desperate

if the "couple of bucks" ends up being the cost of an entire team, then hire a small team to do it.

Then get mad at them because they don't "produce value", and fold it into a developers job with an even higher level of abstraction again. This is what we always do.

I don't see how traffic in Ashburn is more expensive than Frankfurt and Amsterdam.

It's the sort of place where people say Transit is cheaper than paid peering. (For eyeball networks at least).

I think carrying traffic from Europe for some images and videos might make sense financially. But there's always bulk CDN's

They probably just use the local power grid. You can use ElectricityMaps to look up the average carbon intensity per kWh of those grids

I haven't used it personally, but https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... looks amazing as a way to setup and manage kubernetes on Hetzner. At the moment I'm on Oracle free tier, but I keep thinking about switching to it to get off... Well Oracle.

Ive also been using Cluster-API + Cluster-API-Provider-Hetzner

https://github.com/syself/cluster-api-provider-hetzner

works rock solid

i recently read an article about running k8s on the oracle free tier and was looking to try it. i'm curious, are there any specific pain points that are making you think of switching?

I've got a couple of free arm machines setup as a cluster for learning k8 + a few LB in front of it. I use k3s, with pg rather than etcd. Been a great learning experience.

Earlier quoted context omitted.

This is definitely some ChatGPT output being posted here and your post history also has a lot of this "While X, Y also does Z. Y already overlaps with X" output. I'd like to see your breakdowns as well, given that the cost difference between a 2 vCPU, 4GB configuration (as an example) and a similar configuration on AWS is priced much higher. There's also https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne...…

It is my ouput, but I use ChatGPT to fix my spelling and grammar. Maybe my prompt for that should be refined in order to not alter the wording too much.

While using ChatGPT for enhancing your writings is not wrong by any means, reviewing the generated output and re-editing when necessary is essential to avoid robotic writing style that may smell unhuman. For instance, these successive paragraphs: "In contrast, using AWS.." and "In essence, with AWS.." leaves a bad taste in your brain when read consecutively.
