= Iyini Ingqalasizinda ye-BareMetal ku-Azure? =
I-Microsoft Azure inikezela ngengqalasizinda yamafu enohlu olubanzi lwezinsizakalo zamafu ezihlanganisiwe ukuhlangabezana nezidingo zebhizinisi lakho. Kwezinye izimo, nokho, ungadinga ukusebenzisa izinsizakalo kumaseva ensimbi angenalutho ngaphandle kongqimba lwe-virtualization. Ungase udinge ukufinyelela kwezimpande nokulawula isistimu yokusebenza (OS). Ukuze kuhlangatshezwane nalesi sidingo, i-Azure inikela nge-BareMetal Infrastructure yezinhlelo zokusebenza ezinenani eliphezulu nezibalulekile
I-BareMetal Infrastructure yenziwe ngezimo ezizinikezele ze-BareMetal (i-compute cases). Ifaka phakathi:
- Isitoreji esisebenza kahle kakhulu esifanelekile kuhlelo lokusebenza (i-NFS, ISCSI, ne-Fiber Channel). Isitoreji singakwazi futhi ukwabelwa kuzo zonke izimo ze-BareMetal ukuze kunikwe amandla izici ezifana namaqoqo aphumayo noma amapheya okutholakala okuphezulu nge-STONITH
- Isethi yama-LAN abonakalayo aqondene nomsebenzi othile (ama-VLAN) endaweni engayodwa
Le ndawo futhi inama-VLAN akhethekile ongawafinyelela uma usebenzisa imishini ebonakalayo (ama-VM) kunethiwekhi eyodwa noma ngaphezulu ye-Azure Virtual Networks (VNets) ekubhaliseni kwakho kwe-Azure. Yonke indawo imelwe njengeqembu lensiza ekubhaliseni kwakho kwe-Azure
I-BareMetal Infrastructure ihlinzekwa ngama-SKU angaphezu kuka-30 ukusuka kumaseva angu-2-socket kuya kumasokhethi angu-24 kanye nenkumbulo esukela ku-1.5 TB kuya kuma-TB angu-24. Isethi enkulu yama-SKU iyatholakala futhi ngememori ye-Optane. I-Azure inikeza uhla olukhulu kakhulu lwezimo zensimbi ezingenalutho efwini le-hyperscale
== Kungani i-BareMetal Infrastructure? ==
Eminye imithwalo yemisebenzi ebhizinisini iqukethe ubuchwepheshe obungadizayinelwanga ukuthi busebenze esimisweni samafu esibonakalayo. Zidinga izakhiwo ezikhethekile, izingxenyekazi zekhompuyutha eziqinisekisiwe, noma osayizi abakhulu ngokungavamile. Yize lobo buchwepheshe bunokuvikelwa kwedatha okuyinkimbinkimbi kakhulu nezici zokuqhubeka kwebhizinisi, lezo zici azakhelwe amafu abonakalayo. Zizwela kakhulu ukubambezeleka nomakhelwane abanomsindo futhi zidinga ukulawula okwengeziwe kokuphathwa koshintsho nomsebenzi wokulungisa
I-BareMetal Infrastructure yakhiwe, yaqinisekiswa, futhi ihlolelwa isethi ekhethiwe yezinhlelo ezinjalo. I-Azure yaba ngeyokuqala ukunikeza izixazululo ezinjalo, futhi selokhu yahola ngephothifoliyo enkulu kunazo zonke nezinhlelo eziyinkimbinkimbi kakhulu.
Izinzuzo ze-BareMetal
I-BareMetal Infrastructure ihloselwe imithwalo yemisebenzi ebalulekile edinga isitifiketi ukuze iqalise izinhlelo zokusebenza zebhizinisi lakho. Izimo ze-BareMetal zinikezelwe kuwe kuphela, futhi uzoba nokufinyelela okugcwele (ukufinyelela kwezimpande) ohlelweni lokusebenza (OS). Uphatha i-OS nokufakwa kohlelo lokusebenza ngokwezidingo zakho. Ukuze uvikeleke, izimo zihlinzekwa ngaphakathi kwe-Azure Virtual Network (VNet) ngaphandle kokuxhumeka kwe-inthanethi. Izinsizakalo ezisebenza emishinini yakho ebonakalayo (i-VMs), nezinye izinsiza ze-Azure kunethiwekhi efanayo ye-Tier 2, ezingaxhumana nezimo zakho ze-BareMetal.

**Ukwesekwa kwezindawo** kubhekisela ezindaweni ezitholakalayo ngaphakathi kwesifunda lapho izimo ze-BareMetal zingasatshalaliswa kuzo zonke izindawo ukuze kube nokuqina okuphezulu nokutholakala. Leli khono linika amandla usekelo lokukalwa okusebenzayo kwezindawo eziningi
== Ukuphatha izimo ze-BareMetal e-Azure ==
Ngokuya ngezidingo zakho, i-topology yesicelo se-BareMetal Infrastructure ingaba yinkimbinkimbi. Ungase usebenzise izimo eziningi endaweni eyodwa noma ngaphezulu. Izimo zingaba nesitoreji esabiwe noma esinikelwe, kanye nokuxhumeka okukhethekile kwe-LAN ne-WAN. Ngakho-ke nge-BareMetal Infrastructure, i-Azure inikeza ukubonisana ne-CSA/GBB emkhakheni ukuze isebenze nawe
Ngesikhathi i-BareMetal Infrastructure yakho ihlinzekwa, i-OS, amanethiwekhi, umthamo wesitoreji, ukubekwa ezindaweni nezifunda, kanye nokuxhumana kwe-WAN phakathi kwezindawo kakade sekulungisiwe. Usulungele ukubhalisa amalayisensi akho e-OS (BYOL), lungiselela i-OS, futhi ufake isendlalelo sohlelo lokusebenza
Uzobona zonke izinsiza ze-BareMetal, nesimo sazo kanye nezimfanelo, ku-portal ye-Azure. Ungakwazi futhi ukusebenzisa izimo futhi uvule izicelo zesevisi namathikithi okusekela asuka lapho
== Imodeli yokusebenza ==
I-BareMetal Infrastructure ihambisana ne-ISO 27001, ISO 27017, SOC 1, kanye ne-SOC 2. Iphinde isebenzisa imodeli yelayisensi yokuletha-yakho (BYOL): I-OS, umthwalo okhethekile womsebenzi, nezinhlelo zokusebenza zezinkampani zangaphandle.
Ngokushesha nje lapho uthola ukufinyelela kwezimpande nokulawula okugcwele, uthatha isibopho salokhu:
- Ukuklama nokusebenzisa izixazululo zokusekela nokubuyisela, ukutholakala okuphezulu, nokubuyisela esimweni sezinhlekelele
- Ukunikeza ilayisense, ukuphepha, nokusekelwa kwe-OS nesofthiwe yomuntu wesithathu
I-Microsoft inesibopho salokhu:
- Ukuhlinzeka nge-hardware yemithwalo yemisebenzi ekhethekile
- Ukunikeza i-OS
== Isitembu sesibonelo se-BareMetal ==
Isitembu sesibonelo se-BareMetal sihlanganisa lezi zingxenye ezilandelayo:
I-Computing:Amaseva asekelwe ekukhiqizeni ama-Intel Xeon processors anikeza amandla adingekayo okwenza ikhompuyutha futhi agunyazwe umsebenzi okhethekile. Inethiwekhi:Indwangu yenethiwekhi enesivinini esiphezulu ehlangene ixhuma ikhompyutha, isitoreji, nezingxenye ze-LAN. Isitoreji:Ingqalasizinda efinyelelwa ngendwangu yenethiwekhi ehlanganisiwe
Ngaphakathi kwengqalasizinda eqasha abantu abaningi yesitembu se-BareMetal, amakhasimende atshalwa kubaqashi abangabodwa. Lapho uthumela umqashi, uqamba okubhaliselwe kwe-Azure phakathi kokubhaliswa kwakho kwe-Azure. Lokhu okubhaliselwe kwe-Azure yikhona okukhokhiswayo ezimweni zakho ze-BareMetal
Qaphela
Ikhasimende elithumela isenzakalo se-BareMetal lihlukaniswa libe isiqashi. Isiqashi sihlukaniswa kunethiwekhi, isitoreji, kanye nesendlalelo sokubala kwabanye abaqashi. Isitoreji kanye namayunithi wokubala anikezwe abaqashi abahlukene abakwazi ukubonana noma ukuxhumana ngesikhathi sabo se-BareMetal
== Uhlelo lokusebenza ==
Ngesikhathi sokunikezwa kwesibonelo se-BareMetal, ungakhetha i-OS ofuna ukuyifaka emishinini
Qaphela
Khumbula, i-BareMetal Infrastructure iyimodeli ye-BYOL

== Inethiwekhi ==
Ukwakhiwa kwezinsizakalo zenethiwekhi ye-Azure kuyingxenye ebalulekile yokuthunyelwa ngempumelelo kwemithwalo yemisebenzi ekhethekile ezimweni ze-BareMetal. Kungenzeka ukuthi akuzona zonke izinhlelo ze-IT ezitholakala e-Azure kakade. I-Azure ikunikeza ubuchwepheshe benethiwekhi ukwenza i-Azure ibukeke njengesikhungo sedatha esibonakalayo ekusetshenzisweni kwakho kwesoftware esemagcekeni. Ukusebenza kwenethiwekhi ye-Azure edingekayo ezimweni ze-BareMetal kufaka:
- Amanethiwekhi we-Azure axhunywe kusekethe ye-Azure ExpressRoute exhuma kumafa akho enethiwekhi asendaweni
- Isekethe ye-ExpressRoute exhuma ezakhiweni ne-Azure kufanele ibe nomkhawulokudonsa omncane ongu-1 Gbps noma ngaphezulu
- Uhlu Olusebenzayo Olunwetshiwe kanye ne-DNS e-Azure, noma isebenza ngokuphelele e-Azure
I-ExpressRoute ikuvumela ukuthi unwebe inethiwekhi yakho yasendaweni ibe yifu le-Microsoft ngoxhumano oluyimfihlo ngosizo lomhlinzeki wokuxhumana. Ungasebenzisa
**I-ExpressRoute Local** yokudlulisa idatha okungabizi kakhulu phakathi kwendawo okuyo nesifunda sase-Azure oyifunayo. Ukuze unwebe ukuxhumeka kuyo yonke imingcele yezwe, unganika amandla i-**ExpressRoute Premium**
Izimo ze-BareMetal zihlinzekwa ngaphakathi kwebanga lekheli le-IP leseva yakho ye-Azure VNet
I-architecture ebonisiwe ihlukaniswe izigaba ezintathu:
Kwesokunxele:Ibonisa ikhasimende ingqalasizinda esemagcekeni esebenzisa izinhlelo zokusebenza ezihlukene, exhuma ngozakwethu noma irutha yomphetho wasendaweni njenge-Equinix. Ukuze uthole ulwazi olwengeziwe, bheka Abahlinzeki bokuxhumana nezindawo: I-Azure ExpressRoute. Isikhungo:Sibonisa i-ExpressRoute elungiselelwe kusetshenziswa ukubhalisa kwakho kwe-Azure okunikeza uxhumano kunethiwekhi ye-Azure edge. Kwesokudla:Ibonisa i-Azure IaaS, futhi kulokhu, ukusetshenziswa kwama-VM ukusingatha izinhlelo zakho zokusebenza, ezihlinzekwa ngaphakathi kwenethiwekhi yakho ebonakalayo ye-Azure. Ngezansi:Ibonisa usebenzisa i-ExpressRoute Gateway yakho enikwe amandla nge-ExpressRoute FastPath yokuxhumana kwe-BareMetal enikeza ukubambezeleka okuphansi
Ithiphu
Ukuze usekele lokhu, i-ExpressRoute Gateway yakho kufanele ibe yi-UltraPerformance. Ukuze uthole ulwazi olwengeziwe, bheka amasango enethiwekhi ebonakalayo ye-ExpressRoute
