Akekho osebenzisa ngokungathi sína i-AWS/GCP/Azure ukuze abe nama-VM ambalwa noma amaseva azinikezele ewodwa. Uma umuntu ekwazi ukwenza umsebenzi wakhe ogcwele isib. U-Hetzner ngaphandle kokuhlupheka okuningi ngakho-ke akufanele asebenzise noma yimaphi amanye amapulatifomu amafu kwasekuqaleni njengoba azobe ekhokha ngokweqile.

MHLELI: Ngifuna ukucacisa ukuthi ngeshwa ngiyazi ukuthi ezinye izinkampani zisebenzisa i-big 3 njengabahlinzeki be-VPS abalula kodwa kubonakala sengathi wonke umuntu uyavuma lapha ukuthi kuwukumosha imali futhi lokho kungenye yamaphuzu ami abalulekile, yingakho futhi ukuqhathanisa ezinkulu vs i-Hetzner noma yimuphi omunye umhlinzeki we-VPS ezinikezele / ozinikezele weseva akusizi ngalutho njengoba esebenzisa amacala ahlukene okusebenzisa.

Ngicabanga ukuthi ubukela phansi kakhulu inani lamakhasimende amafu enza ukuphakamisa nokushintsha okulula

(Okubi kakhulu kwakuwuhlelo olufinyelela phezulu mhlawumbe ngokushaya okungu-5 ngesekhondi phakathi nesikhathi esimatasa sokuphela kwenyanga esihlala kuma-pods amaningi kuqoqo le-GCP Kubernetes.)
Ngenze lokho kanye ekuqaleni kwangaphambili. Kuyavunywa, bekuyiminyaka eyi-10 edlule, kodwa ukusuka ku-infra eshibhile ukuya ku-AWS kugcine kube uhhafu wezindleko zalokho okwakuphindwe kabili i-infra (sakha i-geo-redundancy ephelele ngesikhathi esifanayo)

Iningi lamakhasimende ami lenza lokho kanye - nje i-EC2 ku-AWS

Yebo, isipiliyoni sami singase singameli icala eliphakathi, kodwa ngokuqinisekile akuwona "akukho muntu". Ngikholwa ukuthi iningi liyakwenza ngoba i-AWS/Azure "inketho ephephile"Ukukhetha i-AWS/Azure inguqulo yesimanje ethi "Akekho owake waxoshwa ngokuthenga i-IBM"--
Ngisanda kuzama u-Hertzner ngokwami ​​futhi ngiyayithanda isipiliyoni okwamanje. Ngiyaqaphela ukuthi ngiqhathanisa ama-apula namawolintshi lapha kodwa; I-Hertzners UI ishesha kakhulu futhi ilula uma iqhathaniswa ne-AWS futhi amanani entengo mahle. Ngisho nama-invoyisi abo ahlanzekile futhi ayaqondakala

Uma bezokwenza lokho kungani bengakhethi okungenani i-Lightsail?
Akuwona wonke amabhizinisi anquma ukuthi lokho kuyingozi okufanele incishiswe, kodwa amanye enza

Ngiyazi ifu lingenza umqondo kodwa hhayi kanje

Hmm, noma yini engenaso ithrafikhi enkulu ngokuhlanya kanye nezidingo, futhi kulezo zimo abathengisi bamafu abakhulu basashibhile futhi kulula ngokwanele kulawo macala okusebenzisa.

I-Hetzner ibonakala ilingana nekhasimende "elingelikhulu ngokwanele ukuthola izaphulelo ezinkulu nokusekelwa kodwa likhulu ngokwanele ukuba nezikweletu ezinkulu zamafu"futhi lokho kulungile.

Izinkampani eziningi nabantu benza imithwalo engasetshenziswa kangcono ku-hardware ezinikele ku-EC2 ngoba "ifu">U-Hetzner ngaphandle kokuhlupheka okuningi ngakho-ke akufanele asebenzise noma yimaphi amanye amapulatifomu amafu kwasekuqaleni njengoba azobe ekhokha ngokweqile.


 Ikhono lokuhlinzeka, ukususa ukunikezwa, ukuhlanganisa, ukulayisha ibhalansi nokuphatha ngaphandle kokukhuluma nabantu, ukulinda i-hardware noma ngisho nokuqonda ngokuningiliziwe ukuthi kwenzekani (yebo lokhu kubi, kodwa namanje ) kungesinye sezizathu ezinkulu. ifu lidumile. Ababungazi abaningi abazinikele sebengcono kakhulu kule ndawo

Kuyenzeka ngempela. Bakha isoftware ethile, bayisebenzise ku-VM futhi bathi isoftware isebenzisa insizakalo yedatha efiphalayo esusa ikhanda lokugcina izipele, okubekwe eceleni, ukuphinda uthole isikhathi, idatha evikelekile ekuphumuleni.

Nginemibhalo emibalwa yegobolondo eyenza konke lokho futhi ngisebenzise i-Hetzner kodwa ngiyakwazi ukucabangela inhlangano ethile ngemali eyanele ukuze ngingabi nandaba nenani lokusebenziseka kalula komunye umuntu onakekela idatha yakho.

Sebevele bakhokhela ifu nomuntu ozophatha izinto zabo zefu ngibheje ukuthi bazokhipha uhhafu wokuthi uma unikeza imibhalo yakho

Ngicabanga ukuthi lokho kukhombisa nje ukuthi laba bahlinzeki bamafu bawumbhedo kangakanani uma ungavele ubhale imibhalo ethile ukuze uyiphathe.
Ngikholwa ukuthi ngiyakholwa ;) Ngivumelanisa leyo nemikhiqizo ethile engiyithuthukisela amakhasimende ami. Nokho akusifanele isikhathi sami sokuzihlupha ngokukhulula lezo ezisesimweni esijwayelekile. Kungazelelwe kuzomele ngenelise izithiyo eziqondile ze-bazillion kanye nezidingo zabasebenzisi abajwayelekile

Ngiyajabula ukuthi ngihlala ngibona ukuthi le nkampani inhle kangakanani muva nje

- Umuntu ojwayele ukuthosa amaseva we-lil hetzner ukuze ajabule
Ngiyaqonda ukuthi awukaze uthole ukuhlaselwa kwesikali 'esikhulu'kodwa kuthatha u-$5 ukuze wehlisele phansi iseva ye-hetzner (kucatshangwa ukuthi awazi ukuthi ungayenza kanjani ngokwakho)

Ukwandisa inkumbulo ibe ngu-128 GB, okungukuthi kuma-DIMM amabili esiteshini ngasinye, kwehlisa isivinini sememori, kakhulu ku-AMD (DDR5-3600) kune-Intel (DDR5-4400)

Ukweqisa inkumbulo, njengakumakhompuyutha amageyimu, ngeke kwamukeleke kumakhompyutha eseva

Kodwa-ke eyokuqala yami yayivame ukuqala kabusha ngokungahleliwe futhi ukusekelwa kwakungelona usizo kakhulu. Bathi angivele ngiqashe enye, ngakwenza. Okwesibili kwaqala kabusha ngokungahleliwe kanye ngonyaka. Ngicabanga ukuthi eyokuqala iye endalini futhi isaqala kabusha ngenjabulo

U-Hetzner uzizwa njengomhlinzeki wefu wesaphulelo esiqinile. Ngisabakhetha ngaphezu kwe-AWS noma i-Azure yemisebenzi engabalulekile enesabelomali esincane
Ngababuza ngesinye sezigameko, bathi i-breaker ephakela i-rack inakho. Ngingacabanga ukuthi lokho kuyimbangela evamile yale nkinga

Enye inkinga ukwehluleka kwediski. Bashintsha idiski ngokushesha okukhulu (<1hr) kodwa ngaphandle kwalapho uzimisele ukukhokhela idiski elisha sha alingana nanoma yini anayo esitokweni. Kwesinye isikhathi lokho kubonakala kuyiyunithi uqobo esondele ekufeni, futhi kwezinye izinyanga ezimbalwa, qagela ukuthi kwenzekani. Ikakhulukazi bakunikeza okuthile okunengqondo ukuze konke kuphumelele ekugcineni

AbakwaHetzner bangabahlinzeki bamafu besaphulelo. Ngemali, empeleni ngijabule ngabo. Okuwukuphela kwenketho enengqondo endaweni yentengo efanayo kungaba ukuzibamba futhi angiqiniseki nakancane ukuthi kungakufanelekela lokho

Kuqale ukusolwa njengezinhlobo ezithile ze-RAM, ngakho-ke ngacela ukushintshwa kwe-RAM ngeshwa okungazange kungisize. Bese kuba isibuyekezo se-BIOS nakho esingakusizanga. Omunye wabe esethola ukuthi i-nohz=off ku-KCL iyilungisile inkinga futhi ngayisebenzisa ngempumelelo ngale ndlela iminyaka embalwa. Ngemva kwesikhathi eside okungenani i-dist-upgrade eyodwa ngakhumbula lokho futhi ngasusa inketho futhi, futhi iseva isasebenza kahle.

Akukho ukuziphatha kwangempela kule ndaba engicabanga ukuthi, kodwa okungenani ukusekelwa kusabela kakhulu, futhi njengoba umsuka wawungacacile ngaleso sikhathi akazange angabaze ukushintshanisa izinto ezingahleliwe uma ucelile. Futhi ube ne-HDD engalungile ngeSonto eledlule kuseva eyodwa futhi wacela ukushintshwa, abakwenza phakathi nemizuzu engama-20 ngivule ithikithi.

Ngicabanga ukuthi kungaba umkhuba omuhle ukubika iseva ku-hetzner nakuba

Hhayi ukwehlisela isipiliyoni sakho, kodwa ngokweqiniso, okuhlangenwe nakho kwami ​​​​ngokusekelwa kwe-Hetzner ngokuvamile kube kuhle ngokungalindelekile. Ayeshesha kakhulu ukuphendula, avame ukuqala ngokushesha kunoma yini inkinga yami uma nginikeza ulwazi olwanele ethikithini lokuqala, njll. Futhi ngokungafani ne-OVH, angizange ngizwe sengathi ngidinga ukubashayela ucingo ukuze ngithole. isevisi ehloniphekile. Kuyamangaza ukuzwa ukuthi isixazululo sabo sithi "ukuqasha esinye"Isipiliyoni esimnandi sisonke kimi, ikakhulukazi uma kubhekwa ukuthi amaseva ashibhe kangakanani. Okuwukuphela kwezifiso zami zangempela kungaba amaseva azinikezele e-US noma eCanada, futhi mhlawumbe okuthile phakathi kwe-1Gbps engalinganisiwe kanye neminikelo ye-10Gbps enemitha -- ukwazi ukuqhuma ngaphezu kwe-gigabit ngezikhathi ezithile ngaphandle kokukhokha imali yomkhawulokudonsa engu-1/TB kungaba kuhle.

I-IIRC uthola i-30tb/ngenyanga ifakiwe - ngakho-ke "ayikhokhi lutho uma iqhathaniswa ne-tb yokuqala"- kodwa ngingaba nephutha - angikabi nawo amaphrojekthi lapho i-10gbps inengqondo.

Kungaba inketho embi ebhizinisini, noma kunjalo, njengoba bengingeke ngifune ukuthembela kumuntu othile ku-Reddit uma kukhona okungahambi kahle ngendlela enyantisayo. I-WalkerServers ingesinye isibonelo somunye wabathengisi be-LeaseWeb abashibhe kakhulu  Isevisi yabo ibilokhu ingenasici futhi amaseva abo avele asebenze  Bengisebenzisa amaqoqo e-k8s ku-hetzner isikhathi eside manje futhi ukuguquguquka kwentengo yikho kanye engikulindele kumsingathi!
Manje ngalokhu okungeziwe uHetzner uvala elinye igebe elenze amaphrojekthi achitha izinkulungwane ezengeziwe ebhizinisini. Ngakho-ke angigcini nje ngokujabula kodwa futhi ngiyaziqhenya ngokuthi baqhubeka nokusungula izinto ezintsha!
Ngangivame ukusebenzela iqembu elaliqasha inqwaba yamaseva kubo futhi sasiba nokwehluleka kwediski cishe njalo ngemva kwesonto ngalinye, okwakudinga ukudala ithikithi lokusekela nokubacela ukuthi bashintshe idrayivu ukuze sakhe kabusha uhlu lwe-RAID.

Basebenzise amadrayivu wabathengi be-SATA avamile futhi mhlawumbe ayemadala noma avuselelwe noma okuthile

Ngijabule kakhulu ngo-Hetzner ngomsebenzi omningi

* Nakuba i-GCP (emuva lapho kwakuyi-AppEngine nje) yayingahlali ngale ndlela futhi njengabasebenzisi be-GAE ngaphakathi kwe-Google bekufanele sibhale amakhodi ethu ngalokho ebesikulindele ukuthi kungaphumeleli, ukuzama futhi, ukuhlehla njll.

Ngokusobala ukufaka esikhundleni sezici ze-AWS ezifana ne-RDS multi-AZ masters ngeke kube lula futhi kungase kudingeke ukukhokha yonke inkokhelo ye-AWS, kodwa lokho kuncike ngempela kusayizi webhizinisi, ithrafikhi, ulwazi lwangaphakathi nezinye izici eziningi.

Nge-hetzner - ukwehluleka kusho ukuthi ukuqapha kwakho kutholwe ukwehluleka kwediski, kukuthumelele isexwayiso se-pagerduty, okumele uhlole isixwayiso, uthole ukuthi yini ehlulekile, bese uthumela ithikithi lokusekela ukuze kushintshwe idiski. Lokhu kuzothatha amahora ambalwa, ngemva kwalokho kufanele wakhe kabusha uhlu lwakho lwe-RAID, futhi ngethemba ukuthi awasekho amadiski ahlulekayo. Ngaso sonke isikhathi sisebenza ngokusebenza okonakele

(Ungangizwa kabi, i-hetzner _great_, ngiyisebenzise iminyaka futhi ngincoma kakhulu ezimweni eziningi - kodwa umqondo wokuthi ukwehluleka nokuthembeka kwabo kufana "nefu"kuyinto efiselekayo)
Ku-AWS, kukhona okuphuka njalo. Isevisi eyodwa kwezingu-100 izohlale inezinkinga zokusebenza, ukutholakala okonakele noma okunye okuqhubekayo

Ku-Hetzner, i-hard drive, i-CPU noma i-RAM komunye wemishini izoba khona njalo ngemva kweminyaka embalwa. Kungenzeka

(Lokhu kushintsha njengoba isevisi yakho ikhula futhi ikhula, kodwa kunenani eliphakeme lethrafikhi elingathathwa yimishini embalwa.)
Ngibe nesibopho sokusebenzisa izigidi zamadola ze-AWS kule minyaka eyishumi edlule. Ngike ngaba ne-AWS cishe enguziro edale isikhathi sokuphumula ngaleso sikhathi ngaphandle kwezinkinga ezimbalwa ezinkulu ezithinte umhlaba wonke (ngokwesibonelo lokho kucisha okukhulu kwe-S3) - kodwa "ama-100s ezinsizakalo azohlala enezinkinga zokusebenza noma ukutholakala okonakele"awakaze bekuyiqiniso kimi. Ngike ngaba namakhulu ezikhathi ngithathe umhlalaphansi - kodwa konke lokho kuyazenzakalela futhi akunasikhathi sokuphumula

Ezinyangeni ezingu-18 ezidlule enkampanini yami yamanje, sibe nesikhathi sokuphumula esingu-100% - akukaze kube nesigameko esisodwa se-AWS esisithinte e-us-east-2. Futhi njengoba sisebenzisa i-ECS ne-fargate, akuzange kudingeke sikhathazeke ngokuthatha umhlalaphansi


 Ngakolunye uhlangothi - ngiphinde ngaba namaseva amaningi womuntu siqu ne-hetzner phakathi neminyaka edlule - futhi i-hardware yi-_old_. Ngibe nama-hard drive okungenani ama-3 ahamba kabi eminyakeni engu-8 edlule

Futhi, ngisancoma kakhulu i-hetzner ezimweni eziningi - kodwa ngicabanga ukuthi kubalulekile ukungena ekuqondeni umehluko wemfanelo yezinto ezifana nokuqapha izinga lehadiwe.

Ngakho-ke ngicabanga ukuthi ungasola iqembu lakho ngoku-oda i-sata yabathengi?

>Bekusabalulekile ngoba ishibhile, kodwa ishibhile ngoba akuyona i-hardware entsha nethembekile

Awahlukile ngempela kunefu, awathengi amaseva aphezulu, azenzela okwawo njenge-hetzner, ngeyunithi eshibhe kakhulu yokusebenza ngakunye.

Umbiko omkhulu wolimi lwesiJalimane: httpswww.golem.de/news/besuch-im-rechenzentrum-so-betreib..

Izinga lokushisa le-CPU: 40C
Ngisho ifu likaHerzner lisebenza nje angazi ukuthi likwenza kanjani kodwa lishibhile

Uma unamaseva angu-500 isikhathi eside, futhi iskripthi esisha sithola ukuthi u-5% unokwehluleka kanye nama-imeyili angu-25 ngesikhathi esifanayo, ngiyabona ukuthi kungani u-Hetzner angase afune i-imeyili eyodwa. Izinombolo zenziwe, kodwa uthola umqondo

Kuyinto nje okufanele ukwenze ngokwakho nge-Hetzner

Ngiyazisebenzisa, futhi ngijabule kakhulu ngakho kokubili amanani, ukwethembeka kanye nesevisi

Okubi kuphela okungaba khona mayelana nabo: ama-IP abo amile awahlali "ehlanzekile": Ngibe nezimo ezimbalwa lapho i-IP engabelwe yona yafakwa ohlwini lwabangavunyelwe futhi kwathatha ukubuya naphambili nesevisi yabo yamakhasimende ukulungisa inkinga ( uthole i-IP entsha)

Kodwa ngaphandle kwaleso silinganiso sekhwalithi / samanani siphezulu kakhulu kune-GCP, i-AWS ne-ilk yazo

Ngiphinde ngisebenzise i-OVH, ihloniphekile futhi, ku-ballpark efanayo ne-Hetzner

Ingabe leyo akuyona inkinga ozohlala uthola nayo $noma yimuphi umhlinzeki? Ngeke wazi ukuthi ngubani obekade ephethe leyo IP nokuthi benzani ngayo

Isibonelo bengizama ukuthuthela iqembu elikhulu lokushintshisana ngiye ehhovisi 365 muva nje futhi umsizi wabo wokuthuthela kwelinye izwe akakabuyekezwa ukuze asekele i-auth yesimanje yehhovisi 365 phakathi kwezinye izinto.

Futhi ukuthutha kuhlulekile kuma-akhawunti abo ngesizathu esithile

Ngokuqondene ne-theips: yebo lokho kuyenzeka kodwa akulona iphutha le-hetzners, njengoba i-ip owawuyabele isusiwe “kumlingisi omubi” ngaphambilini. Uma utshela umenzeli wakho wokwesekwa lokho, ngithole entsha ngaphandle kwenkinga

so your machine doesn't have a fit when the disk is detached. Or equivalent

For example I have loads of stuff on Linode but always make sure I keep backups off-linode, incase I get a random TOS account shutdown and they stop speaking to me etc
IT departments really need to revise their due diligence processes. I wonder how many folks were coerced to do a similar migration just to benefit from household brand credibility

Does anyone have experience to share with that kind of setup? What's the maintenance like?
I use single dedicated server that costs ~40EUR/month, AX41-NVME, and each runner is a separate user account to allow for some isolation


Depending on your setup, you might need to spent some time adjusting jobs to have proper setup/cleanup and isolation between them (but it's not really Hetzner specific, just general issue)

We provision them with ~200 lines of shell script, which we get away with because they are not running a "prod" workload. Don't forget to run "docker system prune" on a timer! Overall these machines have been mostly unobtrusive and reliable, and the engineers greatly appreciate the order of magnitude reduction in github actions time. I've also noticed that they are writing more automation tooling now since budget anxiety is no longer a factor and the infrastructure is so much faster

My only issue is that security scanners cant run on self-hosted runners (GitHub refuses the artifact result, so technically, they do run, but the results fail to upload)

Do you have any alternatives? I thought Hetzner was fairly unique in their dedicated server offerings (for the price, I mean)

Recent Linux kernels finally support these CPUs (do they have full support but if you host a service where you want predictable (and fast) response times why you use the mix of both cores? Or would you just turn off those efficient cores for the server-side usage?
I'm assuming you don'tyourself in the foot by running strictly single-threaded workflow explicitly pinned to the efficiency cores

> running strictly single-threaded workflow explicitly pinned to the efficiency cores
Those cores are slower than e.g. the cores from the (Desktop) AMD CPU we tested at the same time (offered from Hetzner). So it is rather expensive and inefficient to use Intel (Desktop) CPUs for server-side applications as we can only use their performance cores

When these guys open up dedicated servers in a USA region it's going to be huge. Unfortunately, at the moment only the cloud offering is available in the USA so you're stuck with a bit of latency round tripping to the EU

Weird. It seems like they are reading the origin header or something and just redirect HN users to the root of the website

Works fine if you copy the link and paste it in a new tab

Amazon has done an amazing job of convincing people that their hosting choice is between cloud (aka, AWS) or the higher-risk, knowledge intensive, self-hosting (aka, colocation). You see this play out all the time in HN comments. CTOs make expensive and expansive decisions believing these are the only two options. AWS has been so good at this, that for CEOs and some younger devops and developers, it isn't even a binary choice anymore, there's only cloud


Do yourself, your career, and your employer a favor, and at least be aware of a few things

First, there are various types of hosting, each with their own risk and costs, strength and weaknesses. The option that cloud vendors don't want you to know about are dedicated servers (which Hetzner is a major provider of). Like cloud vendors, dedicated server vendors are responsible for the hardware and the network. (If you go deeper than say, EC2, then I'll admit cloud vendors do take more of the responsibility (e.g. failing over your database))

Second, there isn't nearly enough public information to tell for sure, but cloud plays a relatively minor role in world-wide server hosting. Relative to other players, AWS _is_ big (biggest? not sure). But relative to the entire industry? Low single-digit %, if that. The industry is fragmented, there are thousands of players, offering different solutions at different scales

For general purpose computing/servers, cloud has two serious drawbacks: price and performance. When people mention that cloud has a lower TCO, they're almost always comparing it to colocation and ignoring (or aren't aware of) the other options

Performance is tricky because it overlaps with scalability. But the raw performance of an indivisible task matters a lot. If you can do something in 1ms on option A and 100ms on option B, but B can scale better (but possibly not linearly), your default should not be option B (especially if option A is also cheaper)

The only place I've seen cloud servers be a clear win is GPUs

The primary deciding factor is always security. You simply cannot use any small vendor because of the physical security (or the lack thereof). Unless of course you do not care about security. If a red team can just waltz into you DC and connect directly to your infra is it game over for some businesses. You can easily do this with most vendors

The secondary deciding factor is networking. Most traditional co-los have very limited understanding of networking. A CCIE or two can make a real difference. Unfortunately those guys usually work some bigger companies

The third deciding factor air conditioning and electricity considerations.case you are facing an OVH situation. httpswww.datacenterdynamics.com/en/opinions/ovhclouds-dat

(It is really funny, because I have warned them that their AC/cooling solution is not sufficient, and they explained to me that I am wrong. I was not aware of the rest (wooden elements, electricity fuckups, etc.)
During the year, an article in VO News by Clever Technologies claimed there were flaws in the power design of the site, for instance that the neighboring SBG4 facility was not independent, drawing power from the same circuit as SBG2. It's clear that the site had multiple generations, and among its work after the fire, OVHcloud reported digging a new power connection between the facilities
The fourth would be probably pricing. TCO is one consideration, after you made sure that the minimum requirements are met, but only after

So based on the needs somebody can choose wisely, based on the business requirements For example, running an airline vs running a complex simulations have very different requirements

From a sales point of view, I agree with you that, for a lot of folks, this might be the main concern. If you're doing B2B or government work this might be, by far, the most important thing to you

However, this is at least partially pure sales and security theatre. It's about checkboxes and being able to say "we use AWS" and having everyone else just nod their head and say "they use AWS."
I'm not a security expert (though I have held security-related/focused programming roles), but as strong as AWS is with respect to paper security, in practice, the foundation of cloud (i.e. sharing resources), seems like a dealbreaker to me (especially in a rowhammer/spectre world). Not to mention the access AWS/Amazon themselves have and the complexity of cloud-hosted system (and how easy it is to misconfigure them (1 About 8 years ago, when I worked at a large international bank, that was certainly how cloud was seen. I'm not sure if that's changed. Of course, they owned their own (small) DCs

(1) - httpsnews.ycombinator.com/item?id=26154038 The tool was removed from github (conspiracy theory but I still find the discussion there relevant

so, anywhere where your workloads or data are physically co-located on the same hardware as someone else's should be automatically disqualified, right?
Doing your career a favor is how we ended up in this situation in the first place. The tech industry had way too much free money floating around that there was never any market pressure to operate profitably, so complexity increased to fill the available resources

This has now gone on long enough that there are now entire careers built around the idea that the cloud is the only way - people that spend all day rewriting YAML/Terraform files, or developers turning every single little feature into a complex, failure-prone distributed system because the laptop-grade CPU their code runs on can't do it synchronously in a reasonable amount of time

All these people, their managers and decision makers could end up out of a job or face inconvenient consequences if the industry were to call out thecollectively, so it's in everyone's best interest to not call it out. Im sure there are cloud DevOps people that feel the same way but wouldnt admit it because its more lucrative for them to keep pretending


This works at multiple levels too, as a startup, you wouldn't be considered "cool" and deserving of VC funding (the aforementioned "free money") if you don't build an engineering playground based on laptop-grade CPU performance rented by the minute at 10x+ markup. You wouldn't be considered a "cool" place to work for either if prospective "engineers" or DevOps people can't use this opportunity to put "cloud" on their CVs and brag about solving self-inflicted problems

Clueless, non-tech companies are affected too - they got suckered into the whole "cloud" idea, and admitting their mistake would be politically inconvenient (and potentially require firing/retraining/losing some employees), so they'd rather continue and pour more money into the dumpster fire

A reckoning on the cloud and a return to rationality would actually work out well for everyone, including those who have a reason to use it, as it would force them to lower their prices to compete. But as long as everyone is happy to pay theirmarkups, why would they not take the money?

For one, people generally underestimate the performance cost of their choices. And that reaches from app code, to their db and their infrastructure

Were talkingof magnitude of compounding effects. Big constant factors that can dominate the calculation. Big multipliers on top

Horizontal scaling with all its dollar cost, limitations, complexity, maintenance cost and gotchas becomes a fix on top of something that shouldnt be a problem in the first place

Personally, so far, the best near-equivalent provider I've found that actually offers well-specced machines in North America, is OVH, with their HGR line and their Montreal DC. Are there any other contenders?
And if not, why not? what's so hard about getting into the high-spec dedicated hosting space in the US specifically? Import duties on parts, maybe? (I've found plenty of low-spec bare-metal providers in the US, and plenty of high-spec cloud VM hosting providers in the US, and plenty of high-spec bare-metal providers outside the US; but so far, no other high-spec bare-metal providers in the US.)
[1] httpsservicestack.net/blog/finding-best-us-value-cloud-pr..

We're currently using these at OVH: httpswww.ovhcloud.com/en-ca/bare-metal/high-grade/hgr-hciand we really need the cores, the memory, the bandwidth, and the huge gobs of direct-attached NVMe. (We do highly-concurrent realtime analytics; these machines run DBs that each host thousands of concurrent multi-second OLAP queries against multi-TB datasets, with basically zero temporal locality between queries. It'd actually be a perfect use-case for a huge honking NUMA mainframe with "IO accelerator" cards, but there isn't an efficient market for mainframesso they're not actually price-optimal here compared to aof replicated DB shards running on commodity hardware.)

Also they'll run off with your money if you can't provide an ID after you've already paid. No service but no refunds either

But seriously, there's been lots of talk on HN recently about alternatives to the big. This is it - rent a big server and do it all on Linux

Is anybody aware of anything that's price competitive in the US (or within a 50ms ping)?
[1] httpswww.ionos.com/servers/value-dedicated-server#package..

OVH [1] is not quite as cheap, but I can't really think of anyone else in the area that is totally comparable. One draw of OVH, Hetzner, etc, for me over the truly small, cheap dedicated server providers is they both have pretty decent networks and free DDoS mitigation, which is really nice for things like game servers and such where CloudFlare isn't an option

OVH's sub-brands like SoYouStart [2] will sell you decently specced dedicated servers started at around $30 a month in Quebec, which tends to be more than good enough for most of my "US" needs

They do have a couple datacenters in the United States too, not just Canada (+ quite a few in Europe, one in Singapore, some in Australia, etc), but I believe the Virginia/Oregon servers aren't available on the cheaper SYS site -- still cheap, though, but not quite $30 cheap

[1]: 
[2]:  (main downsides compared to OVH proper is the connection is capped at ~250Mbps, and although all servers have DDoS mitigation, the SYS and Kimsufi servers don't allow you to leave it on 24/7 -- so when you get attacked, it might take a minute or so to kick in, and then it'll remain on for 24 hours, I believe)
Edit1: missed word;
Edit2: people pointed below that the us locations don't have dedicated servers, cloud servers only;
