+1 for Hetzner, it's amazing -- I'm particularly fond of their dedicated server offerings. One of the things about Kubernetes I like most is the likelihood that it reduces the barrier to entry for "PaaS land" (and resultingly "cloud land") for providers like Hetzner (see OVH's recently announced k8s offering[0]). Once these "baremetal" providers get in the managed (by k8s) game, I'm certain companies will start to spring up and offer/chip away at cloud provider offerings like S3/RDS/etc -- they'll just connect to your k8s infrastructure, and bring their kubernetes-compatible know-how. This is going to cause prices to plummet, as it will make the tiers of value added services more distinct -- i.e. "a platform to run things" on vs. "really good managed databases".

  What’s the network of Hetzner like? I like their offering, especially the AMD Epyc servers seem to give a great bang for the buck, but I am a bit put off by their low 99.9% network uptime guarantee. https://www.hetzner.com/rechtliches/agb https://www.hetzner.com/rechtliches/agb

    I'm using both their dedicated servers and the cloud offering and never had any issues. Speed and latency are consistent both within Europe as well as to the US (not monitoring much traffic to Asia). Latency from their DCs in Germany to Frankfurt is around 3ms, so comparable to the central Europe offerings of most cloud providers.

      So their network hasn’t had any downtime? Any idea why they would only guarantee 99.9% uptime on their network?

        I've been a hetzner customer for the past 5.5 years now, so far I've received 21 emails from their status reports as follows: 10 from failures (2 or 3 of which directly affected me), 10 emails stating when planned maintenance of certain resources will occur 1 email to let me know of the spectre and meltdown vulnerabilities. So far i'm pretty happy customer, and sending business their way and migrating client's sites to their cloud offerings.

        In the past two years, I remember they have done scheduled infrastructure maintenance twice and unscheduled interruption for a few hours. So, no, it's not 100%. But, AWS has also had some interruptions. From personal experience, this Hetzner downtime has simply been negligible enough. Bigger issue have been replacing commodity memory a few times, which could have been avoided by paying a few more dollars for more quality.

        I haven't noticed any downtime either -- all my downtime has been my own doing -- I only run a few small sites and periodically staging versions of client applications so I don't have a crazy amount of load. I've been using Hetzner for roughly 2 years and am a pretty happy customer. I can say though that the latency is pretty bad when compared to local options -- their server are pretty geographically far from where I and others who use some of my apps access from, and I get ~200ms of latency that I can't do much about. I've looked a traceroute and it's not their network but rather some points in between.

  actually I'm pretty sure ovh and gcloud do run the backplane on k8s itself, that's why it is so cheap

Hetzner lists VMs that are ultra cheap but then has separate listing for more expensive VMs with dedicated cores. Alibaba does the same. With these shared core machines, I wonder what the performance reliability guarantees available and how it compares to the dedicated core machines.

  Depending on your data I'd also wonder about the security restrictions between tenants. It's a thing I consider on AWS as well depending on what I'm doing.

    Do shared cores add any attack vectors other shared machines (with dedicated cores) don't have?
    - grogenaut 8y ago
      There are always risks with shared harware, known and unknown veunerabilities in the hypervisor or hardware. All the recent intel stuff, row hammer, etc. The interesting question comes when people start implementing hardware hypervisors and what is the risk profile there. Security, at the end of the day, isn't about what is secure and what isn't. If you want to be secure, don't get on the internet. Everything else is a exercise in risk tradeoffs and mitigation. If I was doing anything with PII, cc#'s or any other data I never want to touch I wouldn't use shared hardware without hard thought on it.

        Shared hardware from the big cloud players adds attack vectors, but it also comes with some of the best security minds trying to keep the entire platform secure. For example, they'll typically be on secret mailing lists and aware of security vulnerabilities weeks before you know about them.

Indeed, cloud+dedicated infrastructure is really cheap after certain load/volume, compared to pure GCE/AWS. I have been using k8s with Hetzner for 6 months now, with dirt-cheap SSD/NVMe storage and 1080 GPUs. Can't recommend them enough, and I do not really see any competition here.

I like Hetzner's offerings. Wish they're also in North America and Asia.
