Nβchifukwa chiyani anthu akuchulukirachulukira kusankha zochita zoterezi? Ponena za mitambo yapagulu, zonse zimamveka bwino. Inenso ndimawona mitambo yapagulu ngati malonda akulu, ngati china chake chigwera pamenepo (ndipo mitambo yonse imagwa posachedwa), imagwera pamenepo kwa nthawi yayitali. Chitsanzo ndi Amazon yodziwika bwino yomweyi, yomwe nthawi ina idagona kwa masiku angapo pamodzi ndi ntchito yofunikira yosonkhanitsa deta yachipatala ya telemetric, kuphatikizapo chidziwitso cha mtima wa odwala omwe amagwiritsa ntchito pacemaker, omwe anali kuyang'aniridwa ndi madokotala, angapo. anthu anafa ... Ndipo posachedwapa, pamene Bitrix wathu wamakampani anali atagona, zinapezeka kuti chifukwa chake chinali chakuti ogwira ntchito, omwe anali kuzimitsa makina ena, chifukwa cha typo, anazimitsa mfundo zambiri kuposa zofunikira, kukhudza ma node oyang'anira, chifukwa chake makina enieni adayambiranso mkati mwa maola 5 chifukwa cha kukula kwakukulu kwamagulu ... za mtambo ndi mapulojekiti ena kapena kusowa kwa luso loyendetsa mwachangu zida zake kuti zikwaniritse zosowa zanu.
Pankhani ya mitambo yachinsinsi, mwachidziwitso, virtualization imathandizira kupezeka ndi kuchira kwatsoka. M'malo mwake, pali zochitika zambiri pomwe izi sizomveka:
Pakakhala zovuta zaukadaulo pa node, nthawi yopumira ya mphindi 15-30 ndiyovomerezeka.
Sikuti ma projekiti onse amafunikira nthawi yowonjezera pafupifupi 100%, kupatula ana asukulu omwe amazolowera kulipira dola imodzi ndipo amafuna 100%. Kwa ma projekiti ena, nthawi yotsimikizika ya 99,9% ndiyoposa njira yovomerezeka. Chifukwa 0,1% ndi kusapezeka kwa munthu pazipita mphindi 44 pamwezi, zomwe zingachitike pazifukwa zosiyanasiyana zosakonzekera - chifukwa hardware kulephera kapena kusapezeka maukonde. Timatsimikizira nthawi yowonjezera pa intaneti pa 99,99% pamayankho okhazikika, omwe amalola kusapezeka kwa mphindi 4 zokha pamwezi. Ngati seva ilumikizidwa ndi mayendedwe odziyimira a 2 omwe amadutsa m'malo osiyanasiyana olumikizirana komanso omwe magalimoto awo amakonzedwa ndi ma cores odziyimira pawokha, nthawi yotsimikizika ya network imawonjezeka kangapo. Izi zimapangitsa kuti zitheke kukwaniritsa zofunikira za nthawi yayitali ngakhale mabanki omwe kusapezeka kwa mphindi 40 pachaka ndikovomerezeka, malinga ndi certification. Zowona, nthawi zosapezeka ndizosowa kwambiri. M'zaka za 5 zogwira ntchito ndi malo opangira deta, sipanakhalepo nthawi yomwe ma seva onse anakhala osapezeka panthawi imodzimodzi chifukwa cha mavuto ndi intaneti kapena magetsi. Ngakhale pamene ku Netherlands kunali mdima wakuda padziko lonse lapansi ndipo malo ena ambiri a data sanapezeke - ena anaiwala kuwonjezera injini za dizilo, ena analibe mphamvu zokwanira za UPS, m'malo athu osungiramo ma data ocheperapo peresenti ya ma seva sanapezeke kwakanthawi kochepa. nthawi. Ma seva ena omwe makasitomala amabwereketsa kwa ife, ngakhale akale, omwe amawoneka ngati achikale, omwe amatha kulephera kuposa mayankho atsopano, sanakhazikitsidwenso ngakhale kamodzi pazaka 3, monganso zaka 3 sanatayikepo. . Kodi kusapezeka kwa mphindi 30 ndikovomerezeka kwa zaka zitatu? Kuposa, ngakhale kwa mabanki.
Ndipo funso lomveka likubuka, chifukwa chiyani mumalipira? N'zosachita kufunsa kuti simuyenera kudalira mwamwayi ndipo nthawi zonse muzichoka pa mfundo yosungika bwino. Lamulo lalikulu lomwe ndidadzipezera ndekha ndi ili: kusungitsako kuyenera kukhala kopanda ndalama zambiri kuposa zotayika zomwe zingachitike pakachitika nthawi yosapezeka chifukwa chosowa kusungitsa kotere. Ndiye kuti, ngati nthawi yotsimikizika imalola kusapezeka kwa mphindi 40 pamwezi, ndipo pakapanda nthawi yotereyi, zotayikazo zimakhala mazana angapo kapena chikwi chimodzi - kubwereketsa njira yowonjezeramo kuti muwonjezere chitsimikizo cha nthawi yayitali. alibe nzeru. Chifukwa kwenikweni, ma seva sadzakhalapo mwezi uliwonse kwa mphindi 40; Mphindi 40 zosapezeka ndi chitsimikizo, choyipa kwambiri. Zomwe sizikugwiritsidwa ntchito pamwezi, monga momwe zasonyezera.
Mwanjira iyi, ma seva amatha kukhala ofunikira popanda kukhala ofunikira kwambiri, ndipo eni ake a polojekiti akapanda kusamala posinthira katunduyo ku seva ina yodzipatulira, titha kupewa zovuta zomanga gulu la failover ndikugawana kusungidwa kwa failover.
Zokolola zochepa ndizosavomerezeka panthawi yogwira ntchito. Makasitomala athu ambiri amasankha zitsulo zopanda kanthu kuchokera ku Dell ndendende pazifukwa izi; ndizotsika mtengo komanso zopindulitsa kwambiri kugwiritsa ntchito zida zonse panthawi yogwira ntchito, zomwe sizingachitike, monga tafotokozera kale, kuposa kubweza ndalama zambiri pamtambo. njira ndi ntchito zomwezo mumtambo, zomwe zingawononge kangapo kuposa yankho lodzipereka. Mtambo ndi kuphatikizana sikungakwaniritse zosowa zazinthu ndipo sizingakhale zotsika mtengo kwa makasitomala otere.
Olembetsa safuna kulipira zambiri pa ntchito yomwe ili ndi mphamvu zochepa. Makasitomala athu ambiri ndi makampani ang'onoang'ono omwe alibe madipatimenti awoawo aukadaulo komanso ndalama zogulira zida zawo. Kugula hardware kungakhale nkhonya kwenikweni kwa iwo ndipo osapereka ntchito yokwanira, chifukwa m'kupita kwa nthawi hardware imakhala yachikale, ndipo ndizochititsa manyazi kutaya zipangizo zamtengo wapatali ngakhale patatha zaka 3, panthawi yomwe kampaniyo yakula ndi chinthu chabwino. chofunika. Ngati mubwereka Dell R730xd kuchokera kwa ife, muli ndi mwayi wosinthira ku seva ina nthawi iliyonse kapena pakatha chaka ngati mutasankha njira yobwereka ndi mgwirizano wa chaka chimodzi. Kuphatikiza apo, pali mwayi wosunga pakulipira malayisensi a VMware.

Koma kuti akwaniritse zofunikira za Google yemweyo, makasitomala ena amafuna kuti pamangidwe ma network otchedwa demilitarized network (DMZ networks) - maukonde okhala ndi chitetezo chowonjezereka, zomwe zikutanthauza kukhalapo kwa firewall ya hardware yomwe imalepheretsa kupeza zida ndikukulolani bisani zofunikira kuseri kwa firewall ndikuwonjezera chitetezo.
Ndipo zonse zili bwino pamene yankho lotere likulamulidwa nthawi yomweyo, koma ndizovuta kwambiri kukhazikitsa kusinthaku popanda nthawi yopuma, zomwe zachitika posachedwa kwa mmodzi wa makasitomala athu, ndi polojekiti yokonza zopempha za visa kwa nzika zochokera m'mayiko osiyanasiyana. za dziko, kumene kuli kosafikirika ngakhale mβmaola kungadzetse kutayika kwa makumi masauzande a madola. Koma tinapeza yankho, tinapita kumsonkhano, kuyika zipangizo zowonjezera m'chipinda chosungiramo, kusuntha zipangizo zosafunika kwenikweni, ndikuyatsa chowotcha moto molingana ndi ndondomeko, monga momwe kasitomala amafunira, kuti athe kuchita kusamukako popanda nthawi yopuma.

Mwina chiwembuchi chidzakhalanso chothandiza kwa wina akamasamuka, popeza akatswiri opanga ma data samafuna kuwona zinthu zodziwikiratu nthawi zonse, koma amaumirira kuti pakhale nthawi yopumira ya maola 2 kuti musinthe kuseri kwa firewall, koma ndikufunsani mokoma mtima - yitanitsani firewall ya hardware zonse pasadakhale ngati mukufuna. Ndife osinthika komanso okonzeka nthawi zonse, koma nthawi zina mphamvu zathu zimatha kukhala zochepa.
M'mabuku amtsogolo, tidzayesa kuyesa mayeso angapo owonjezera ndikugawana zomwe takumana nazo pogwiritsa ntchito nsanjazi zomwe zithandizira kumvetsetsa bwino pakusankhidwa kwa njira yabwino kwambiri. Kupatula apo, ndizodabwitsa kuwona kuti RAID0 ya ma drive awiri a SSD, pamilandu yokhala ndi katundu wambiri, imatha kukhala yocheperako kuposa yolembera padera, chifukwa chake timalandila zopempha za NVMe PCIe SSD nthawi. ku nthawi. Ndizotheka kuti tiwonetsa zochitika zogwira mtima kwambiri zopezera mayankho, kugawana zina zowonjezera pomanga magulu angapo a RAID mkati mwa wowongolera m'modzi wa RAID ndizothandiza, ndikuwonetsa momwe magawo awiri odziyimira pawokha a RAID10 a ma drive 4 adzakhala abwino kuposa gulu limodzi la RAID10 la 8. Ndi liti pamene kudzakhala kothandiza kugwiritsa ntchito RAID1 pa TempDB, ndi RAID5 pa china chirichonse. Ndipo mungatani popanda NVMe PCIe SSD mukakhala ndi bajeti yochepa.
