Server-yada cloud-ka ee is-ballaariya (Auto scaling): VM-kaaga oo toos u weynaada adigoo aan damin
Server-kaaga cloud-ka ah wuxuu ku darayaa vCPU iyo RAM muddo 2–4 ilbiriqsi ah marka uu ciriirigu bato. Uma baahna dib-u-bilaabid (restart), xiriirka ma go'o, mana dhaafo xadka aad u goysay.
- Adiga ayaa horay u dejinaya xadka ugu sarreeya, tusaale ahaan ilaa 4 vCPU iyo 8 GB RAM. Marna ma dhaafeyno xadkaas.
- Miyuu CPU-gu sarreeyaa dhowr daqiiqo oo xiriir ah? VM-ku wuxuu isu beddelayaa cabbirkaas isagoo shaqeynaya, 2–4 ilbiriqsi gudahood.
- Kusoo celi cabbirkii hore markaad doonto: hal gujis oo batoonka "Dib u bilow si aad ugu celiso cabbirkii hore" ah, qiyaastii 1–2 daqiiqo.
Auto scaling xilliga ciriiriga taraafikada: hal galab
Hal fiid oo baahin toos ah (livestream) oo uu galay macmiil Cloudj:
Culays caadi ah
Cabbirka asalka ah, qiimaha asalka ah
Culays badan dhowr daqiiqo
Wuxuu toos ugu weynaadaa xadkaagii, qiimo sare
Ciriiriga ka dib
Qiimo sare ilaa aad ka riixdo ku celi cabbirkii hore
Khadka dhibcaha leh waa xadka culeyska server-ka aad dejisay. Qaybta hadhka leh waa qiimaha sarreeya — iskii uma dhammaado, wuxuu soconayaa ilaa aad ka riixdo batoonka si uu ugu noqdo cabbirkii hore.
Auto scaling iyo cabbir-beddelka gacanta: maxay ku kala duwan yihiin
| Beddel cabbirka (adigaa riixaya) | Auto Scaling (annagaa kuu riixeyna) | |
|---|---|---|
| Yaa go'aaminaya | Adiga | Annaga, annagoo adeegsaneyna xadadka aad dejisay |
| Goorta ay dhacayso | Isla marka aad riixdo Codso (Apply) | Kaliya marka uu server-ka VM culays xad-dhaaf ah galo |
| Waxaad bixinayso | Hadda ayaa lagaa jarayaa, cabbirka cusubna waa mid rasmi ah | Kaliya saacadaha uu VM-ku sida dhabta ah ugu shaqeeyay cabbirka weyn |
| Ma beddeli karaa disk-ga | Haa | May — disk-gu iskii weligii uma kordho |
| Hoos u dhigista cabbirka | Haa, waxay qaadaneysaa dib-u-kicin ~70 ilbiriqsi ah | Marnaba iskayno uma yarayno — wuxuu ku negaanayaa cabbirka weyn iyo qiimihiisa ilaa aad ka riixdo batoonka dib-u-celinta (~1–2 daqiiqo) |
Labaduba waxay ku yaallaan hal daaqad: geli cabbirka aad rabto, ka dib dooro inuu hadda dhaqangalo ama kaliya marka uu VM-ku culays galo.
Qiimaha Auto scaling: bixi kaliya saacadaha uu ku shaqeeyo cabbirka weyn
Qiimuhu wuxuu si toos ah ula socdaa cabbirka saxda ah ee aad dooratay. Marnaba waxba kama xisaabinno gudaha VM-kaaga. Lacagta saxda ah waxay ka muuqanaysaa shaashadda ka hor inta aadan riixin batoonka — ma jiraan qaansheegyo lama-filaan ah.
Marka uu server-ka VM koro, qiimaha cusub ee saacaddii wuxuu bilaabmayaa isla daqiiqaddaas, wuxuuna soconayaa ilaa aad ka riixdo batoonka si uu ugu noqdo cabbirkii hore — qiimuhu iskii hoos uguma soo dhaco marka culeysku yaraado.
Tusaale: waxaad xadka sare ka dhigtay labanlaabka cabbirkaaga hadda. Fiid 4 saacadood ah oo culays badani jiro waxay kugu kacaysaa kaliya farqiga 4-taas saacadood — ee maaha bisha oo dhan.
Xadka ugu sarreeya adigaa had iyo jeer gacanta ku haya: cabbirka aad dejiso waa kan ugu dambeeya. Marnaba kama talaabsanno.
Dib ugu soo celinta cabbirkii hore marka ciriirigu dhammaado
Server-ka farsamada gacanta (virtual machine) dib uma soo celin karo CPU iyo RAM inta uu shaqeynayo — taasi waa xaddidaad dabiici ah oo virtualization-ka laftiisa leeyahay, shirkad kasta oo weyn oo adeeg bixiyana way leedahay. Sidaas darteed, VM-ku ISKII ISUMA yareeyo marka uu bannaan yahay: wuxuu ku negaanayaa cabbirka uu gaaray iyo qiimihiisa u dhigma.
Adigaa go'aaminaya goorta aad hoos u dhigayso, adigoo hal batoon riixaya: "Dib u kici si aad ugu noqoto cabbirkii hore". VM-ku wuu istaagayaa ka dibna dib u bilaabmayaa, qiyaastii 1–2 daqiiqo, ka dibna wuxuu ku shaqeynayaa cabbirkii hore iyo qiimihii hore. Xogtaada, disk-gaaga iyo ciwaanka IP-gaaguba siday ahaayeen ayay ahaanayaan.
Haddii aadan waligaa riixin, VM-ku wuxuu si toos ah ugu negaanayaa cabbirka weyn — ma jiro waqti xaddidan mana jiro wax si toos ah u dhacaya. Dib-u-kicin caadi ah, furaha sirta oo la beddelo, ama dib-u-rakibidda nidaamka OS ma beddelaan qaabeynta; kaliya batoonkan ayaa beddeli kara.
Shuruudaha Auto scaling: VM-kaagu ma isticmaali karaa?
- Wuxuu ku shaqeeyaa Linux. Windows weli lama taageero, sababtoo ah ruqsadda Windows Server waxay aqbashaa kaliya 2 CPU sockets.
- Waa in dib loo kiciyay ugu yaraan hal mar tan iyo cusbooneysiintii ugu dambeysay ee nidaamkayaga. Haddii kale, fariinta shaashadda ayaa kuu sheegi doonta waxayna kuu oggolaan doontaa inaad jadwaleyso.
- Wuu shaqeynayaa, mana jirto howlo socda xilligan.
- Ma laha wax snapshots ah — snapshot wuxuu xiraa cabbirka VM-ka. Tirtir iyaga, wax walbana diyaar ayay kuu noqonayaan.
