    I realised I don’t need my servers being online 24/7, so for me that’s Raspberry Pi and equivalents, plus powering on computers on demand.

    A trick I realized a few years ago: Caddy has a module you can build it with that does WOL. So I was able to run a Caddy reverse proxy that woke up my higher powered server on demand, and let it go back to sleep when I wasn't using it. Might be a bad idea for a database sever, but for my uses it was pretty simple and effective.

    Oh wow, that’s really cool! I do use Caddy too.

    Is it that your service/website is on both (low powered server and high powered one) or is it only on the high powered? So, it’s like

    • the lower powered server knows it needs help (sounds a bit surreal to me, but perhaps it’s doable)
    • or the lower powered server does not serve anything, but wakes up the high powered when the thing is accessed?

    I guess that’s the 2nd thing, but it’s very cool indeed! That way you can really have very convenient things for free, as it’s super cheap to run any hardware for a very while on demand. I don’t mind waiting a minute or even two when I need to access something very infrequently and don’t want to run my server 24/7. I do exactly that, but I wake up it via LAN manually.

    The low powered server is the Caddy server, all it does us act as a reverse proxy for everything in my house, giving it an SSL cert and doing things like WOL. The caddy config basically just says "Here's your reverse proxy target, if you don't get a response within one second, send a WOL packet, wait a couple of seconds, then try again".

    The only requirement is for you to do a custom build of caddy (this is done with a dockerfile), and to have WOL enabled on the high power server.

    It means the first web request for services on the high power server might take a few seconds, but everything after that is smooth.

    Is it that high power server takes a few seconds to boot? What’s the hardware you have there? I’m curious that’s the average boot time for an average high power server? I do use heavily obsolete devices for my personal servers (think of DDR-2 era devices with Intel Atom or sometimes core 2 duo devices) usually without even SSDs. With an SSD, my desktop devices (all DDR-3 era with SATA-3 disks) boot within 20…30 seconds, which is good enough for me. I assume the more modern devices would be quicker, but [single-digit, I assume] seconds sounds very good. To me, that sounds like it’s a no-brainer to have this feature. I was thinking whether I can wait minutes for something I need occasionally to boot. Seconds is just too fast. I think that delay is tolerable even for a commercial / production server, where the expectations are just different.

    I'm not shutting it down, just sleeping it. My high powered server is a gaming PC from a few years ago. Running Linux, my best case scenerio for cold boot would still be 10-20 seconds, but wake from sleep is near instant.

    More likely your system is more sophisticated, I have just joined the hobby, so to say. But I am sure you can go much cheaper than that with bare metal. If I’d really need to host something, I’d rather buy a real server, and invest in solar power instead of paying some rent. Was a happy Digital Ocean customer, before I realised I can do the same with a Raspberry Pi. I was buying a couple of Pis a year for them. Right now, de-facto one Pi can host everything I really need. I regret I wasted about half a thousand on nothing. Could have bought a great NUC instead of wasting money on the cheapest VM for years.

    Yeah solar power is much more affordable these days. I live in a vehicle so I have a 500w panel on the roof charging a 200ah lithium battery. I only use a laptop and steam deck, but could easily upscale. The whole system, including the victron controllers & shunt and the 2k inverter came out around £700, but I'm pretty sure stuff has only got cheaper since I bought it. I have way more power than I need in summer, though there are maybe two months in winter when I have to charge everything in daylight. I could always add a small wind generator if I needed. Renewables are totally feasible these days

    I think I'm at a family of four or five, but I'm alone with my dogs and my weed and my servers. Being able to legally self-host your own drug supply is great.

    ich habe meins nicht vergessen

    Mine blew my socks off, but i smoke so little that I have to grow once a year max.

    This is why im doing my homelab on low powered processors (5825u NAS boards). Runs way cooler and is way more efficient. Same performance as my 9900kf gaming PC cpu wise.

    Edit: this hasn't happened yet

    My solar covers more than my entire electric bills in the mild weather months.

    I was thinking of moving to more modern systems with modest power consumption too. One of the systems I picked up is basically a case-as-a-heatsink with no fans.

    My electric bill last month was $15. It eventually is financially worth it.

    Don't know how hard you went on your home lab, I use office rather than datacenter equipment and it's quite and plenty for my needs. For my professional test/dev needs I have such equipment at work, so I don't need to home train on gear for the sake of competence in the field.

    15 bucks is impressive, yes...i just currently don't care very much for the bills. Dunno even if solar would be great here, we're not on the overly sunny side 😁

    I don't work (and never really did), so home is all there is. Office surely is enough most of the time, especially considering I wouldn't want to pay license fees or be online with stuff. Professional stuff can be pretty shitty in that regard. So I use whatever fits my criteria best.

    It grew more and more to be honest, and it already comes close to be a part-time job that costs money and has no salary 😑

    How does running a server, assuming it's used some amount of internet bandwidth, handle residential internet speeds? If I've got a gig up and down, can I reasonably run like a jellyfin for my friends?

    My isp hasn't complained. I have fiber at my house and symmetrical gigabit. You should be fine if you transcode to reduce bandwidth needed as you still use your own internet. But I'm not running jellyfin on my home server.

    Most servers you rent are only going to have 1Gbps internet speeds too unless you're paying extra, so if you've got symmetrical gigabit at home, you're 100% good to go, except for maybe higher downtime than a datacenter. My fiber at home seems to go out for a bit overnight occasionally as they're doing maintenance.
