Thanks for the awesome work!
I'm not too familiar with Lemmy's codebase, but I am a devops engineer. Is the software written in any way to support horizontal scaling? If so, I'd be happy to consult/help to get the instance onto an autoscaling platform eventually.

Just donated $10! Appreciate all the work you all are doing to keep up with the growth.
Came here from Reddit and I already love it so much more! :)
Is one donation method preferred over another? That is to say, is one cheaper than the other?

What kind of server configuration are you guys running? A single instance?
More power! More power is good.
Just joined. Thank you so much for your effort!
@ruud@lemmy.world DM me if you need help setting up monitoring/alerting on server health. IRL I'm on an SRE team, so happy to help where I can!

Thank you very much! 🥳
So, I just want to make sure I understand this as I am a new user from reddit. Instances are server based and cost money. Instances are Lemmy.World, Beebaw, Lemmy.Film, etc etc. These are all seperate hosted instances. Correct?
And donations would help pay for the server, ie lemmy.world?
"Lemmy instances" are analogous to "email servers": your account is hosted on one of them, but you can communicate with people on other ones, because the servers know how to talk to each other.
Expanding the capacity of the Lemmy service will involve both (1) more instances, and (2) more resources for existing instances.

Thankyou for everything!
For less tech-savvy newbies (like me), in case there is some confusion affecting your urge to engage/donate... My friend gave me a great explanation:
-
Lemmy the platform is planet Earth
-
“Instances” like lemmy.world, lemmy.ml, beehaw.org, etc. are like the different countries on Earth
-
When someone signs up, the user picks one instance to be a part of, like how an Earthling becomes a citizen of a country
-
If you register at lemmy.world, that means your home instance/ “home country” is lemmy.world, but you can “travel” to lemmy.ml, another instance / “country”, to check out and subscribe to their community
-
When you subscribe to a different instance that’s not your home instance, you can still participate in their content, and other people will be able to see which instance / “country” you’re from
-
Each instance can have its own version of the same “subreddit”, so you can have a c/Memes in your home instance that is different from a c/Memes in another instance. But you can subscribe to both separately
-
c/[community name] is the naming convention used here I think like r/[subreddit name] on Reddit. If talking about a community in a different instance, it's c/[community name]@[instance name] so like c/memes@lemmy.ml
-
Donations will help with the cost of running lemmy.world only and not lemmy.ml, beehaw.org, etc.
Someone please correct any of this if any of it is wrong, I’ll happily edit
This seems like a much better explanation for Lemmy compared to the email analogy everyone writes for non-tech savvy people.

Itd be cool to get donation flare!
You can! ☑️ or ✅. The Patreon page mentioned that you're officially allowed to edit your username to add flair when you donate. I upgraded to $8/month specifically so I could add the flair, but then got cold feet about the idea. 😀

Just curious, what sort of hardware is lemmy.world using/moving to? Wondering if there's a good way to predict load based on number of users.
Yes. It’s called performance testing. Basically an engineer would need to setup test user transactions to simulate live traffic and load test the system to see how everything scales, where it breaks, etc. Then you can use the results of the tests to figure out how big of an instance you should use for your projected number of users.
Jmeter, and locust.io are the two biggest open source performance test tools.
The alternative is take a wild guess. See how the system behaves, and make adjustments in real time… like what @ruud@lemmy.world is currently doing.

I don't understand why a dedicated server is a good idea, when the only true way to scale is to use like Kubernetes or Docker and ECS Containers with scale?
Your just gonna run into more problems, you cannot vertically scale forever.
