SLA, yomwe imadziwikanso kuti "mgwirizano wapantchito", ndi mgwirizano wotsimikizira pakati pa kasitomala ndi wopereka chithandizo pazomwe kasitomala adzalandira pazantchito. Limanenanso za chipukuta misozi pakakhala nthawi yopuma chifukwa cha vuto la wogulitsa, ndi zina zotero. M'malo mwake, SLA ndi chidziwitso mothandizidwa ndi malo opangira deta kapena wothandizira wothandizira amatsimikizira kasitomala yemwe angakhalepo kuti adzachitiridwa chifundo m'njira iliyonse. Funso ndiloti mukhoza kulemba chirichonse chomwe mukufuna mu SLA, ndipo zochitika zolembedwa mu chikalatachi sizichitika kawirikawiri. SLA ili kutali ndi chitsogozo posankha malo opangira deta ndipo ndithudi simuyenera kudalira.
Tonse tinazolowera kusaina mtundu wina wa mapangano omwe amaika maudindo ena. SLA ndi chimodzimodzi - nthawi zambiri chikalata chosatheka kuganiziridwa. Chokhacho chomwe mwina chilibe ntchito ndi NDA m'malo omwe lingaliro la "chinsinsi cha malonda" kulibe kwenikweni. Koma vuto lonse ndiloti SLA sichithandiza kasitomala posankha wopereka woyenera, koma amangoponya fumbi m'maso.
Kodi omwe amakhala nawo nthawi zambiri amalemba chiyani mu mtundu wa SLA womwe amawonetsa anthu? Chabwino, mzere woyamba ndi mawu akuti "kudalirika" kwa hoster - izi nthawi zambiri zimakhala ziwerengero kuyambira 98 mpaka 99,999%. M'malo mwake, manambalawa amangopanga zokongola zamalonda. Kalekale, pamene kuchititsa alendo kunali kochepa komanso kokwera mtengo, ndipo mitambo inali maloto chabe kwa akatswiri (komanso mwayi wofikira kwa aliyense), chizindikiro cha nthawi yochititsa chidwi chinali chofunika kwambiri, chofunika kwambiri. Tsopano, pamene onse ogulitsa akugwiritsa ntchito, kuphatikiza kapena kuchotsera, zida zomwezo, khalani pamaukonde a msana womwewo ndikupereka phukusi lautumiki lomwelo, chizindikiro cha uptime ndichosadabwitsa.
Kodi pali ngakhale SLA "yolondola"?
Zachidziwikire, pali mitundu yabwino ya SLA, koma zonse ndi zolemba zosakhazikika ndipo zimalembetsedwa ndikumalizidwa pakati pa kasitomala ndi wopereka pamanja. Kuphatikiza apo, mtundu uwu wa SLA nthawi zambiri umakhudza mtundu wina wa ntchito zamakontrakitala osati ntchito.
Kodi SLA yabwino iyenera kuphatikiza chiyani? Kufotokozera TLDR, SLA yabwino ndi chikalata chowongolera mgwirizano pakati pa mabungwe awiri, omwe amapereka m'modzi mwa maphwando (makasitomala) kulamulira kwakukulu pa ndondomekoyi. Ndiko kuti, momwe zimagwirira ntchito m'dziko lenileni: pali chikalata chomwe chimalongosola njira zogwirira ntchito padziko lonse ndikuwongolera maubwenzi pakati pa maphwando. Imaika malire, malamulo, ndipo payokha imakhala chida champhamvu chomwe mbali zonse ziwiri zingagwiritse ntchito mokwanira. Chifukwa chake, chifukwa cha SLA yolondola, kasitomala akhoza kungokakamiza kontrakitala kuti agwire ntchito monga momwe anavomerezera, ndipo zimathandiza kontrakitala kulimbana ndi "zofuna" za kasitomala wotanganidwa kwambiri zomwe sizikuvomerezeka ndi mgwirizano. Zikuwoneka motere: "SLA yathu ikunena izi ndi izi, tulukani pano, timachita zonse zomwe tagwirizana."
Ndiko kuti, "SLA yolondola" = "mgwirizano wokwanira wopereka mautumiki" ndipo amapereka ulamuliro pazochitikazo. Koma izi ndizotheka pokhapokha ngati mukugwira ntchito "monga ofanana".
Zomwe zalembedwa pa webusaitiyi ndi zomwe zikuyembekezera zenizeni ndi zinthu ziwiri zosiyana
Nthawi zambiri, zonse zomwe tikambirane ndi njira zotsatsira komanso kuyesa kutchera khutu.
Ngati titenga ma hosters otchuka apakhomo, ndiye kuti mwayi umodzi ndi wabwino kuposa wina: 25/8 kuthandizira, nthawi yowonjezera seva 99,9999999% ya nthawiyo, gulu la malo awo a deta osachepera ku Russia. Chonde kumbukirani mfundo yokhuza ma data center, ife tibwerera kwa izo mtsogolo pang'ono. Pakadali pano, tiyeni tikambirane za ziwerengero zoyenera zolekerera zolakwika ndi zomwe munthu amakumana nazo pamene seva yake ikugwerabe mu "0,0000001% ya zolephera."
Ndi zizindikiro za 98% ndi pamwamba, dontho lirilonse ndi chochitika pafupi ndi zolakwika za chiwerengero. Zida zogwirira ntchito ndi zolumikizira zilipo kapena palibe. Mutha kugwiritsa ntchito hoster yokhala ndi "kudalirika" kwa 50% (malinga ndi SLA yake) kwa zaka popanda vuto limodzi, kapena mutha "kulephera" kamodzi pamwezi kwa masiku angapo ndi anyamata omwe amati 99,99%.
Nthawi yakugwa ikafika (ndipo, tikukukumbutsani, aliyense amagwa tsiku lina), ndiye kasitomala akukumana ndi makina amakampani omwe amatchedwa "thandizo", ndipo mgwirizano wautumiki ndi SLA zimawululidwa. Zikutanthauza chiyani:
- Mwinamwake, kwa maola anayi oyambirira a nthawi yopuma simudzatha kusonyeza kalikonse, ngakhale osungira ena amayamba kuwerengeranso mtengo (malipiro a chipukuta misozi) kuyambira pamene ngoziyo inagwa.
- Ngati seva sichikupezeka kwa nthawi yayitali, mutha kutumiza pempho la kuwerengeranso mtengo.
- Ndipo izi zimaperekedwa kuti vuto lidabwera chifukwa cha vuto la wogulitsa.
- Ngati vuto lanu lidayamba chifukwa cha munthu wina (pamsewu waukulu), ndiye kuti zikuwoneka ngati "palibe amene ali ndi mlandu" ndipo pamene vutoli lithetsedwa ndi nkhani ya mwayi wanu.
Komabe, ndikofunikira kumvetsetsa kuti simupeza mwayi wopita ku gulu la uinjiniya, nthawi zambiri mumayimitsidwa ndi mzere woyamba wothandizira, omwe amakulemberani pomwe mainjiniya enieni amayesa kukonza zinthu. Zikumveka bwino?
Pano, anthu ambiri amadalira SLA, zomwe, zikuwoneka, ziyenera kukutetezani kuzochitika zoterezi. Koma, kwenikweni, makampani nthawi zambiri sadutsa malire a zolemba zawo kapena amatha kusintha zinthu m'njira yochepetsera ndalama zawo. Ntchito yayikulu ya SLA ndikudikirira ndikutsimikizira kuti ngakhale zitakhala zosayembekezereka, "zonse zikhala bwino." Cholinga chachiwiri cha SLA ndikulumikizana ndi mfundo zazikuluzikulu ndikupatsa opereka chithandizo kuti azitha kuyendetsa bwino, ndiye kuti, kuthekera kofotokoza kulephera kwa chinthu chomwe woperekayo "alibe udindo".
Nthawi yomweyo, makasitomala akuluakulu, samasamala konse za chipukuta misozi mkati mwa SLA. "SLA compensation" ndi kubwezeredwa kwa ndalama mkati mwa tariff molingana ndi kutha kwa zida, zomwe sizingawononge ngakhale 1% ya kuwonongeka kwandalama ndi mbiri. Pankhaniyi, ndikofunikira kwambiri kwa kasitomala kuti mavutowo athetsedwe posachedwa kuposa mtundu wina wa "kuwerengeranso mtengo".
"Malo ambiri a data padziko lonse lapansi" ndi chifukwa chodetsa nkhawa
Tayika zochitikazo ndi chiwerengero chachikulu cha malo opangira deta pa wothandizira ntchito m'gulu losiyana, chifukwa kuwonjezera pa zovuta zomveka zoyankhulirana zomwe zafotokozedwa pamwambapa, mavuto osadziwika bwino amakhalanso. Mwachitsanzo, wopereka chithandizo chanu alibe mwayi wofikira "malo awo" a data.
M'nkhani yathu yapitayi , chinsinsi chake ndi kugulitsanso mphamvu za anthu ena mwachinyengo chake. Ambiri mwa omwe akukhala nawo masiku ano omwe amati ali ndi "malo awo opangira data" m'magawo ambiri ndi ogulitsa pogwiritsa ntchito mtundu wa White Label. Ndiko kuti, iwo mwakuthupi alibe chochita ndi malo ovomerezeka a data ku Switzerland, Germany kapena Netherlands.
Kugunda kosangalatsa kwambiri kumachitika apa. SLA yanu ndi wothandizirayo ikugwirabe ntchito ndipo ndi yovomerezeka, koma wothandizira sangathe mwanjira ina yake kukhudza kwambiri mkhalidwewo pakachitika ngozi. Iye mwiniyo ali ndi udindo wodalira pa mwiniwake wogulitsa - malo opangira deta, kumene zida zamagetsi zinagulidwa kuti zigulitsenso.
Choncho, ngati mumayamikira osati mawu okongola mu mgwirizano ndi SLA za kudalirika ndi ntchito, komanso luso la wothandizira kuthetsa mavuto mwamsanga, muyenera kugwira ntchito ndi mwiniwake wa malowa. Ndipotu, izi zimaphatikizapo kuyanjana kwachindunji mwachindunji ndi deta.
Chifukwa chiyani sitiganizira zosankha pomwe ma DC ambiri angakhale a kampani imodzi? Chabwino, pali makampani ochepa kwambiri otere. Malo amodzi, awiri, atatu ang'onoang'ono a data kapena imodzi yayikulu ndizotheka. Koma ma DC khumi ndi awiri, omwe theka lawo ali mu Russian Federation, ndipo yachiwiri ku Ulaya, ndizosatheka. Izi zikutanthauza kuti pali makampani ambiri ogulitsa kuposa momwe mungaganizire. Nachi chitsanzo chosavuta:
Linganizani kuchuluka kwa malo a data a Google Cloud. Pali asanu okha a iwo ku Ulaya. Ku London, Amsterdam, Brussels, Helsinki, Frankfurt ndi Zurich. Ndiko kuti, m'malo onse amisewu yayikulu. Chifukwa malo opangira deta ndi okwera mtengo, ovuta komanso ntchito yaikulu kwambiri. Tsopano kumbukirani makampani ochititsa alendo ochokera kwinakwake ku Moscow omwe ali ndi "malo khumi ndi awiri aku Russia ndi Europe."
Palibe, ndithudi, palibe ogulitsa abwino omwe ali ndi oyanjana nawo pulogalamu ya White Label, alipo okwanira, ndipo amapereka ntchito zapamwamba kwambiri. Amapangitsa kuti athe kubwereka mphamvu ku EU ndi Russian Federation panthawi imodzi kudzera pawindo lasakatuli lomwelo, kuvomereza malipiro mu rubles, osati ndalama zakunja, ndi zina zotero. Koma milandu yomwe yafotokozedwa mu SLA ikachitika, amakhala olanda momwemonso momwemo.
Izi zikutikumbutsanso kuti SLA ilibe ntchito ngati simukumvetsetsa momwe bungwe limagwirira ntchito komanso kuthekera kwake.
Chofunika kwambiri ndi chiyani
Kuwonongeka kwa seva nthawi zonse kumakhala kosasangalatsa ndipo kumatha kuchitika kwa aliyense, kulikonse. Funso ndilakuti mukufuna kuwongolera zinthu zingati. Tsopano palibe ogulitsa ambiri mwachindunji pamsika, ndipo ngati tilankhula za osewera akulu, ndiye kuti ali ndi, kunena kwake, DC imodzi yokha kwinakwake ku Moscow mwa khumi ndi awiri ku Europe komwe mungapeze.
Pano, kasitomala aliyense ayenera kusankha yekha: kodi ndimasankha chitonthozo pakali pano kapena kuthera nthawi ndi khama kufunafuna malo opangira deta pamalo ovomerezeka ku Russia kapena ku Ulaya, kumene ndingathe kuika zida zanga kapena kugula mphamvu. Pachiyambi choyamba, mayankho okhazikika omwe ali pamsika ndi oyenera. Chachiwiri, muyenera kutuluka thukuta.
Choyamba, m'pofunika kudziwa ngati wogulitsa ntchito ndi mwiniwake wa malo / deta. Ogulitsa ambiri omwe amagwiritsa ntchito mtundu wa White Label amayesetsa kubisa momwe alili, ndipo apa muyenera kuyang'ana zizindikiro zina. Mwachitsanzo, ngati "ma DC awo aku Europe" ali ndi mayina enieni ndi ma logo omwe amasiyana ndi dzina la kampani yopereka zinthu. Kapena ngati mawu oti "abwenzi" akuwonekera penapake. Othandizira = White Label mu 95% ya milandu.
Chotsatira, muyenera kudziwa momwe kampaniyo imapangidwira, kapena bwino, yang'anani zidazo mwa munthu. Pakati pa malo opangira ma data, machitidwe oyendera maulendo kapena zolemba zapaulendo patsamba lawo kapena mabulogu sizatsopano (tinalemba izi. ΠΈ ), komwe amalankhula za malo awo a data ndi zithunzi ndi mafotokozedwe atsatanetsatane.
Ndi malo ambiri a data, mutha kukonzekera ulendo wopita ku ofesi komanso ulendo wopita ku DC komweko. Kumeneko mutha kuwunika kuchuluka kwa dongosolo, mwina mutha kulumikizana ndi m'modzi mwa mainjiniya. Zikuwonekeratu kuti palibe amene angakupatseni maulendo opanga ngati mukufuna seva imodzi ya 300 RUB / mwezi, koma ngati mukufuna mphamvu yaikulu, ndiye kuti dipatimenti yogulitsa malonda ikhoza kukumana nanu. Mwachitsanzo, timachita maulendo otere.
Mulimonsemo, nzeru wamba ndi zosowa zabizinesi ziyenera kugwiritsidwa ntchito. Mwachitsanzo, ngati mukusowa zomangamanga zogawidwa (ma seva ena ali ku Russian Federation, ena ku EU), zidzakhala zosavuta komanso zopindulitsa kugwiritsa ntchito mautumiki a hosters omwe ali ndi mgwirizano ndi European DCs pogwiritsa ntchito White Label. chitsanzo. Ngati zomangamanga zanu zonse zidzakhazikika panthawi imodzi, ndiye kuti, mu malo amodzi a deta, ndiye kuti ndi bwino kuthera nthawi kuti mupeze wothandizira.
Chifukwa SLA wamba mwina sikungakuthandizeni. Koma kugwira ntchito ndi mwiniwake wa malowa, osati wogulitsa, kudzafulumizitsa kwambiri kuthetsa mavuto omwe angakhalepo.
