The "making it catch up" is the tricky part. You need an initial backup for that. xtrabackup can take that backup "hot" without blocking read/writes. mysqldumper will block writes for whatever time that initial backup takes, for 2TB of data that's going to be hours. 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 th…

Isn't that just a flag? "--lock-tables=false", alternatively --single-transaction for InnoDB.

If you want a consistent backup that you can use to setup a replica you need to block writes while the backup is taken, take the backup while the database is shutdown OR use xtrabackup.

What's the HA plan? Sounds like from the requirement to live migrate you can't really afford planned downtime, so why are you risking unplanned downtime?

The "where's the HA?" comments are missing that this was a single DO droplet before. The migration didn't reduce redundancy, it just moved the single point of failure from one provider to another for 1/6 the cost. The HA conversation is worth having, but it's a separate conversation from this migration.

That’s like saying Mercedes is a scam because you’re fine with a Honda Civic. It’s a totally legitimate preference but not being in the target market doesn’t make something a scam.

AWS ain't no Mercedes. Mercedes feels premium and isn't full of bugs. 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.

Maaan, I have some bad news for you...

A few months ago, I looked into AWS alternatives for my small SaaS side project. My main motivations were to save money and maybe support some EU cloud providers. At first, I planned to go with Hetzner and accepted that I would need to do a lot of things myself. However, the dealbreaker for me was that Hetzner IPs have a bad reputation. At work, I learned that one of the managed AWS firewall rules blocks many (maybe…

Not sure what firewall rules you're referring to, but I'm genuinely surprised to see DO being trusted more than Hetzner. I often see DO's ASN when looking at scrapers/hackers, so I'd say it's only a matter of time until they're blocked as well.

> Surely you must've noticed that pretty much all of their bare metal offerings ("dedicated" and the stuff on "auction") have multiple disks, allowing for various RAID configurations? I don't know where to start with this comment. Do I really need to spell out the difference between cloud and bare metal ? A few examples... - Live migration ? Cloud only. - Snapshots ? Cloud only. - Want to increase disk space ? Tick b…

Well you did say your data is lost when a disk fails, which is not true. Parent pointed out that for you. Yeah you pay for and get additional stuff with cloud. Nobody disputed that.

> Well you did say your data is lost when a disk fails, which is not true.

Well, technically its still a possibility.

I am old enough to have seen issues with RAID1 setups not being able to restore redundancy, as well as RAID controller failures and software RAID failures.

Also, frankly you are being somewhat pedantic. My broader point was regarding cloud. I gave HD Failure as one example, randomly selected by my brain ... I could have equally randomly chosen any of the other items ... but this time, my brain chose HD.

IMO nobody was paying for magic compute. they're paying to not touch ten years of glue. if agents eat that glue, the moat gets thin fast.

> agents eat that glue No wonder they hallucinate :)

It's when they sniff the glue, then things get wild.

Every time I see this kind of article, no one really bothers about sb/server redundancy, load balancers, etc. are we ok with just 1 big server that may fail and bring several services down? You saved a lot of money but you'll spend a lot of time in maintenance and future headaches.

I don't know about Hetzner but with Upcloud and Vultr my single VPS setups have been more reliable than multiregion with redundancy setups with other providers like Fly.

Yeah, well be careful of Hetzner, I used to love them but I just migrated away. They just shut all all of our VMs over a $36 billing dispute. (~30 VMs we were using for our CI/CD pipeline) We provided them evidence with records of the payment in totality from our bank, they refused to look at it / discuss the dispute, even when we were communicating urgently and just ultimately shut off all our access. We're on Scaleway now.
