- reduce dns ttl (if not doing an ip swap)
- rsync website files
- rsync /etc/letsencrypt/ ssl certificates
- copy over database (if writes don't happen often and database is small enough, this can be done without replica, just go read_only during migration)
- test new server by putting new ip in local /etc/hosts
- turn off cron on old server
- convert old server nginx to reverse proxy to new server
- change dns (or ip swap between old and new server)
- turn on cron on new server
I wish the industry would adopt more zero knowledge methods in this regards. They are existing and mathematically proven but it seems there is no real adoption.
- OpenAI wants my passport when topping up 100 USD
- Bolt wanted recently my passport number to use their service
- Anthropic seems wants to have passports for new users too
- Soon age restriction in OS or on websites
I wished there would be a law (in Europe and/or US) to minify or forbid this kind of identity verification.
I want to support the companies to not allow misuse of their platforms, at the same time my full passport photo is not their concern, especially in B2B business in my opinion.
The only possible non legally driven reason I can think of would be if they think the tradeoff of extra friction (and lost customers) is more than offset by fraud protection efforts. This seems unlikely cause I don't see how that math could have changed in the last few years.
Which is fundamental to so many XY problems, including why cloud services are so byzantine instead of just providing isolated secure shells with full root access within them. And why distrust is a growing force in the world instead of, say, unconditional love.
I always dreamed of winning the internet lottery so that I could help dismantle the systems of control which currently dominate our lives. Which starts with challenging paradigms from first principles. That looks like asking why we only have multicore computing in the cloud and not on our desktops (which could be used to build our own cloud servers).
When we're missing an abstraction layer, that creates injustice and a power drain from the many to the few. Some examples:
- CPU -> multicore MIMD (missing) -> GPU (based on the subset SIMD instead of MIMD upon which graphics libraries could be built)
- UDP -> connectionless reliable stream (missing) -> TCP (should have been a layer above UDB not beside it)
- UDP/TCP -> P2P (NAT and other limitations block this and were inherited by IPv6 as generational trauma) -> WebRTC (redundant if we had P2P that "just works")
- internet connection -> symmetric upload/download speed (blocked for legal reasons under the guise of overselling to reduce cost) -> self-hosted web servers (rare due to antitrust issues stemming from said legal reasons)
- internet connection -> multicast (missing due to suppression of content-addressable-memory/hash-tree/DHT/) -> self-hosted streaming (negates the need for regions and edge caching)
I had high hopes for Google and even Tesla (for disrupting the physical world). But instead of open standards, they gave us proprietary vendor lock-in: Google Workspace (formerly G Suite) and NACS instead of J1772 (better yet both). Because of their refusal to interoperate at the lowest levels, there is little hope that they will do the real work of solving the hard problems at the highest levels.
For example, I just heard that China has built thousands of battery swap stations to provide effectively instant charging for electric vehicles, whereas that's something that Tesla can't accomplish because they chose to build Supercharger stations instead.
Once we begin to see the world this way, it's impossible to unsee it. It calls into question the fundamentals (like scarcity) which capitalism is based upon, and even the concept of profit itself.
From a spiritual perspective, I believe that this understanding is what blocks me from using my talents to use the system for personal gain to win the internet lottery. The people who own the systems of control don't have this understanding, and even view its basis in empathy as a liability. So we sacrifice the good of the many for the good of the few and call that progress.
It's bad enough living in America without the rest of the world adopting the grift economy.
Absolutely no to this - reason enough to go with AWS or alternatives. And why are ppl willingly giving it to hosting providers?
Unnecessarily exposing yourself to identity theft if they get compromised.
If Hetzner allows you to host something and you use it for illegal acts, they aren’t going to jail to shield you for €10/month.
And if someone wants to do illegal things, what's stopping them from submitting a fake ID?
They still decided my information was fake and terminated my account.
I'm never going to do business with them again.
But at least if there is an alternative then great.
Not sure what differs in our cases, I'm based in EU.
As I understand it, they ask only from accounts that check several boxes for common cases of abuse. So basically, personal accounts (as opposed to business accounts) from poor countries (by per capita, so e.g. India qualifies as poor).
Sure, it cost me £6/mo to serve ONE lambda on AWS (and perhaps 500 requests per month). Sure it was awesome and "proper". But crazy expensive.
I host it now (and 5 similar things) for free on Cloudflare.
But if you need what AWS provides, you'll get that. And that means sometimes it's not the most cost-effective place.
> Sure, it cost me £6/mo to serve ONE lambda on AWS (and perhaps 500 requests per month)
On the other hand, we have dozens production workloads on Lambda handling thousands of requests daily and we spend like $50/mo on Lambda.
I'm really intrigued by what you did to get to those figures!
AWS and Azure a charging an arm and a leg, but the offered quality is mostly perceived. Most of the bits and bobs they charge for are not providing much value for a vast majority of businesses. I won't even go over the complete lack of ergonomics with their portals.
and mercedes is just like aws in dumb charges. new tires, EUR1000+ for set. replace car keys? EUR1000+
Maaan, I have some bad news for you...
I see you've never actually owned or worked on a German car, especially in relation to even modest Japanese models. Maybe they were a little nicer inside in the 80s and maybe 90s, but "German car" and frankly "European make" is basically synonymous with "big expensive pile of shit that's an expensive pain in the ass when things start falling apart (which they seem to with increasing rapidity)." It's like the disease that plagued British cars for the longest time got contaminated with the German propensity to build overly complex monstrosities.
Recently we had several of our VMs offline because they apparently have these large volume storage pools they were upgrading and suddenly disks died in two large pools. It took them 3 days to resolve.
Hetzner has no integrated option to backup volumes and its roll your own :/ You also can't control volume distribution on their storage nodes for redundancy.
Cloud used to be marketed for scalability. "Netflix can scale up when people are watching, and scale down at night".
Then the blogosphere and astroturfing got everyone else on board. How can $5 on amazon get you less than what you got from almost any VPS (VDS) provider 10 years ago?
It's worse than Oracle and they don't even use lawyery contracts.
The technology itself is the tendrils.
Nice to see it used _twice_ :D
If you’re migrating a large MySQL database and you’re not
using mydumper/myloader, you’re doing it the hard way.
Aside from the blocking you mentioned during the initial snapshot, you'd need to block writes to the old DB before the cutover as well. There's no way to guarantee in-flight writes to the old DB aren't lost when promoting the replica to a primary otherwise. I'm surprised the author didn't go into more detail here. Maybe it was fine given their workload, but the key issue I see is that they promoted the new DB to a primary before stopping the old application. During that gap, any data written to the old DB would be lost.
Once you have that initial back up you can set your replica and make it catch up , then you switch. I choose to take the few seconds of downtime doing the switch because for my use case that was acceptable.
BTW, I've been a client of Hetzner (Cloud, Object Storage, and Storage Box) for a few years now, very happy with them!
