Umqondisi wokuphathwa komkhiqizo we IGoogle imemezele ukufika kweVM E2, umndeni omkhulu wemishini ebonakalayo lokho kwethulwa kusimo se-beta se-Google Compute Engine. I-E2 wumndeni oguquguqukayo wemishini ebonakalayo enamakhono "okuphathwa kwezinsizakusebenza" aletha ukusebenza okuthembekile ngokulungiswa okuguqukayo nezindleko eziphelele kakhulu zobunikazi (i-TCO) yayo yonke eminye imishini ebonakalayo kuGoogle Cloud.
Lo mndeni omusha wemishini ebonakalayo ejwayelekile ujwayelekile ifanele izinhlobo ezahlukahlukene zomthwalo womsebenzi. AbakwaGoogle bathi ngaphandle kwemithwalo yemisebenzi ebiza kakhulu, kufanele ikwazi ukuletha ukusebenza okufana nohlobo lomshini "N1" ngentengo ephansi. Ngokuya nge-Google, lo mndeni wemishini ebonakalayo wenziwa ukuphatha kahle izinsizakalo zayo ezizwela ukubambezeleka futhi eziqondiswe kubasebenzisi.
UJune Yang uthe kubhulogi yakhe:
“Imishini ebonakalayo ye-E2 ilungele imisebenzi eminingi ehlukahlukene, kufaka phakathi amaseva wewebhu, izinhlelo zokusebenza ezibucayi zemishini, imininingwane emincane, nentuthuko nezindawo eziphakathi nendawo. Uma unemithwalo yemisebenzi esebenza kahle ku-N1, kepha ingadingi izimo ezinkulu, ama-GPU endawo, noma ama-SSD, cabanga ukuwahambisa ku-E2. Ubuye wengeza wathi "kubo bonke ngaphandle kwemithwalo yemisebenzi ebiza kakhulu, silindele ukuthi i-E2 ithumele ukusebenza okufanayo kuN1, ngemali ephansi kakhulu."
U-Yang uphinde abike lokho imisebenzi yokuphatha imithombo enamandla iqinisekisa Kunikezwa imishini ebonakalayo ye-E2 ukusebenza okuqhathaniswa nomndeni wakwa-N1 wakwaGoogle, kepha kuqhathaniswa nokulondolozwa okumaphakathi kwamaphesenti angama-31 kuzindleko eziphelele zobunikazi.
Imishini ebonakalayo ebonakalayo nayo iyashintsha kakhulu, ngoba ube nezilungiselelo eziyi-15 ezichazwe ngaphambilini. Lezi zilungiselelo ziyahamba kusuka kuma-vCPU ayi-2 kuphela no-2GB wememori, kufika kuma-CPU ayi-16 no-128GB wememori.
Ngakho-ke, imishini ebonakalayo ithola ukusebenza okuhlala isikhathi eside ngentengo ephansi njalo. Imishini ebonakalayo ye-E2 ingaphatha umthwalo ophakeme we-CPU ngaphandle kwentengo eyinkimbinkimbi, ngokungafani nezinketho ezifanayo ezivela kwabanye abathengisi emakethe, ngokusho kweGoogle.
Imishini ebonakalayo ye-E2 bazosabalalisa kuphela izinsizakusebenza ezidingwa ngumsebenzisi noma ngokwazi ukusebenzisa izinhlobo zemishini yangokwezifiso. Izinhlobo zemishini yangokwezifiso zilungile ngezimo lapho ukulayishwa komsebenzi okudinga amandla wokucubungula amaningi noma imemori ethe xaxa, kepha kungadingi zonke izibuyekezo ezinikezwe ileveli elandelayo yomshini.
Ngamanye amagama, ama-vCPUs zenziwa njengemicu ehlelelwe ukusebenza ngokufunwa njenganoma yimuphi omunye umucu ku-Host: lapho i-vCPU inemithwalo yemisebenzi, inikezwa i-CPU ebonakalayo etholakalayo ukuze iqhutshwe kuze 'ikhululwe ngemuva kokuqedwa komsebenzi.
Ngokufanayo, amamephu we-RAM abonakalayo kumakhasi wokubamba ngokomzimba ngamatafula ekhasi agcwaliswa lapho ikhasi lezivakashi ngokomzimba litholakala okokuqala. Le mephu ihlala ilungisiwe kuze kubonakale umshini obonakalayo ukuthi ikhasi lezivakashi ngokomzimba alisadingeki.
Lapho nje imishini ebonakalayo ibekwe kumsingathi, ukusebenza kwayo kubhekwa ngokuqhubekayo, ngakho-ke uma isidingo semishini ebonakalayo sanda, ukufuduka okubukhoma kungasetshenziswa ukudlulisa umthwalo we-E2 komunye umbuthano esikhungweni sedatha.
Umthwalo womsebenzi uvame ukushintsha ngaphandle kwesikhathi sokulinda, ngenxa yendlela yokubikezela evela kuGoogle. Ngokuya nge-Google, ukufuduka bukhoma kwemishini ebonakalayo kuyingxenye efakazelwe yenjini yekhompyutha futhi ukusebenza kwayo kuqhubeke kuthuthuka ngokuhamba kwesikhathi.
Ukufeza izinhloso zokusebenza kwemishini ebonakalayo ye-E2, I-Google isungule isheduli ye-CPU yangokwezifiso ene-latency engcono nokuziphatha okungcono Uhlelo oluhlanganyelwe kunohlelo oluzenzakalelayo lwe-Linux.
Ishejuli entsha ikhiqiza izikhathi ezingaphansi kwesilinganiso semizuzu engama-microsecond yokuvuka nge-switch eshintshayo esheshayo, esiza ukugcina ukuphathwa kwezinsizakusebenza okunamandla kunganaki cishe noma yimuphi umsebenzi.
