I-VPN ye-EC2 Burstable: amakhredithi e-CPU e-Standard noma e-Unlimited?

Imodi eyodwa inciphisa emgqeni wesisekelo, enye iqhubeka futhi ingase ikukhokhise. Bala izibalo zamakhredithi ngaphambi kokuba i-instance encane ibe igateway yakho.

Igateway ye-VPN encane iphumelela ukuhlolwa kwesivinini, izwakala kahle, bese yehla ngemva kwesidlo sasemini. I-instance yayingaqambi ngamanga ngesikhathi sokuhlolwa; yayisebenzisa amakhredithi eyayiwatholile ngesikhathi ingenzi lutho. Ama-instance e-Burstable enzelwe lokho kanye, okwenza i-benchmark emfushane ibe isibikezeli esibi sendlu yonke yokudluliswa. Zombili izindlela zamakhredithi zehluleka ngezindlela ezihlukene, futhi ukukhetha phakathi kwazo yisinqumo sangempela.

Ukuhlolwa kwesivinini kuboleke kuphi

Ikhredithi eyodwa ye-CPU iyi-vCPU eyodwa esebenza ngokusetshenziswa okugcwele umzuzu owodwa. I-instance ye-Burstable ithola amakhredithi ngezinga lomgqa wesisekelo wayo futhi iwasebenzise lapho idlula lowo mgqa. Ubusuku obungenzi lutho bakha ibhalansi; ikusasa elimatasa liyayidonsa.

Yingakho ukuhlolwa kokuqala kubonakala kukuhle. I-instance yayinesabelomali esigciniwe, yasisebenzisa emsebenzini wokubethela, futhi yabika izinga elinempilo. Akukho lutho kumphumela olutshela ukuthi kwenzekani lapho ibhalansi ifinyelela ku-zero. I-benchmark yalinganisa ukuqhuma, futhi ukuqhuma yikho i-instance eyenzelwe ukukunikeza. Ayizange ilinganise isimo esizinzile ozothembela kuso.

Izibalo okufanele uzenze

Okokufaka iyiphesenti lomgqa wesisekelo nge-vCPU ngayinye, inani lama-vCPU, ibhalansi eqoqiwe, kanye nomthwalo oyilindele. Njengesibonelo kuphela, thatha i-instance yokucabanga enama-vCPU amabili, umgqa wesisekelo wamaphesenti ayishumi nge-vCPU ngayinye, amakhredithi angu-24 aqoqiwe, kanye ne-vCPU eyodwa ematasa ngokugcwele kanti enye ayisebenzi. Lezi zinombolo zingokokufaka okumenyezelwe, hhayi ukucaciswa kosayizi othile we-instance.

Earn rate:       2 x 10% x 60 = 12 credits/hour
Workload usage:  1 x 100% x 60 = 60 credits/hour
Net draw:        60 - 12 = 48 credits/hour
Accrued budget:  24 / 48 = 0.5 hours

Ngaphansi kwalezo zicabango isabelomali siphela cishe ngengxenye yehora. Umsebenzi wangemuva, umthwalo oshintshayo kanye nokubalwa kwe-instance uqobo kuhambisa umphumela, futhi akukho kulokhu okubikezela i-throughput ye-VPN. Okukubikezelayo ukuthi umkhawulo oqhubekayo uzoqala nini ukusebenza.

Qaphela futhi ukufunda kwesibili: kulesi sibonelo i-vCPU eyodwa ematasa ingxenye ecishe ibe yingxenye yonke yomthamo we-CPU. Iphesenti elilinganiselayo lilonke lingafihla umongo ogcwele, ngakho bheka ukuziphatha ngomongo ngamunye eceleni kwezinombolo zamakhredithi.

I-Standard ne-Unlimited: u-zero ofanayo, incazelo ehlukile

Kumodi ye-Standard, ibhalansi ephelile icindezela i-CPU eqhubekayo ibheke emgqeni wesisekelo. I-instance iyaqhubeka nokusebenza, nje kancane, futhi umkhawulo uyabikezelwa. Kumodi ye-Unlimited i-instance ingaqhubeka nokudonsa amakhredithi asele ngemva kokuba ibhalansi ifinyelele ku-zero, futhi ukusetshenziswa okuqhubekayo ngaphezu komgqa wesisekelo kungaveza izindleko ngaphansi kwemithetho yokubalwa yesevisi.

Ngakho i-CPUCreditBalance engu-zero isho ukucindezelwa kumodi eyodwa nokukhokhiswa okungenzeka kwelinye. Yikho konke ukuqhathanisa, futhi yingakho ukufunda imethrikhi ngaphandle kokufunda imodi kudukisa.

Okusele nakho akusona isikweletu esilula ngekhredithi ngayinye. Ukusebenza kwakamuva ngaphansi komgqa wesisekelo kungakhokha ukusetshenziswa okusele, futhi kusebenza eminye imibandela yezindleko. Hlola imodi elungiselelwe kanye nemithetho yamanje yesevisi esikhundleni sokuthembela esimweni sezinga lamahhala esivela kubhulogi endala.

Okufanele ukubheke ngesikhathi somsebenzi wangempela

Rekhoda i-CPUCreditUsage ne-CPUCreditBalance eceleni kwesikhathi nenginga yokudluliswa. Ku-Unlimited, engeza i-CPUSurplusCreditBalance ne-CPUSurplusCreditsCharged. Umhlahlandlela we-AWS wokuqapha amakhredithi e-CPU uchaza ukuthi yikuphi okubikwayo ngayinye nokuthi kangaki.

Hlola futhi ngokuhlanganyela okumelele nangesikhathi esanele ukubona ukuthambekela, futhi rekhoda ibhalansi yokuqala. Ikusasa elingenzi lutho nentambama ematasa akusona isivivinyo esifanayo, ngisho nemiyalo efanayo.

Imikhawulo engeyona i-CPU

Umthamo womnotho wenethiwekhi unomgqa wawo wesisekelo nokuziphatha kwawo kokuqhuma, futhi imikhawulo yezinga lamaphakethe noma yokuxhumeka ingabopha ngaphambi kwe-CPU. Imemori ibalulekile lapho ukusetshenziswa kwe-VPN kugcina isimo sokuxhumeka ngakunye, futhi i-instance encane ingayiphela kude ngaphambi kokuphela kwamakhredithi.

Ngakho ibhalansi yamakhredithi enempilo ifakazela into eyodwa: isabelomali se-CPU akusona isithiyo samanje. Ayisho lutho ngomzila wenethiwekhi, futhi ayisho lutho ngokwenzekayo lapho ukuhlanganyela kuphindwe kabili. Qapha izilinganiso zenethiwekhi efasiteleni elifanayo nezilinganiso zamakhredithi, ukuze ukwehla kwe-throughput kube nesizathu esingaba khona esikhundleni sethiyori.

Ukukhetha umgqa wesisekelo ngamabomu

Sebenzisa umthwalo oqhubekayo olinganisiwe ukukhetha umgqa wesisekelo, noma wamukele ukuqhuma ngokucacile futhi uhlele isabelomali sakho. Zombili izimpendulo ziyavikeleka uma zibhaliwe; akukho nokukodwa okuvikelekayo uma kususelwa kumthombo wevidiyo ophumelelayo womunye umuntu.

Uma i-gateway ithwele umthwalo, thinta imodi yamakhredithi njengengxenye yohlelo lwamandla hhayi njengokuzenzakalela ongakaze ukwivule. Imodi oyikhethayo yiyo iphutha ongalibikezela.
