Ukucabanga lapho isifiso sokuphasa isitifiketi sivela khona I-AWS Solutions Architect Associate.
Isisusa sokuqala: “Izimbazo”
Enye yezimiso eziwusizo kakhulu kunoma yimuphi uchwepheshe ithi “Yazi amathuluzi akho” (noma okunye okuhlukile kwayo “").
Sesihlale emafini isikhathi eside, kodwa okwamanje bekuyizinhlelo zokusebenza ze-monolithic ezinemininingwane esetshenziswa ezimweni ze-EC2 - ezishibhile futhi zijabule.
Kodwa kancane kancane sacinana ku-monolith. Setha inkambo yokusika ngendlela enhle - ye-modularization, bese kuba ngama-microservices asemfashini manje. Futhi ngokushesha okukhulu “izimbali eziyikhulu ziyaqhakaza” kulo mhlabathi.
Kungani uye kude - iphrojekthi yokugawulwa kwemithi engiyenzayo njengamanje ihlanganisa:
- Amaklayenti ngendlela yezinhlelo zokusebenza ezihlukahlukene zomkhiqizo wethu - kusukela emakhoneni akude wefa eliminyene kuya kumasevisi amancane athandwayo ku-.Net Core.
- Imigqa ye-Amazon SQS, equkethe izingodo mayelana nokuthi kwenzekani ngamaklayenti.
- Isevisi encane ye-.Net Core ebuyisa imilayezo esuka kulayini futhi iyithumele ku-Amazon Kinesis Data Streams (KDS). Futhi ine-Web API interface kanye ne-swagger UI njengesiteshi esiyisipele sokuhlola mathupha. Isongwe ngesitsha se-Docker Linux futhi isingathwe ngaphansi kwe-Amazon ECS. I-Autoscaling inikezwa uma kwenzeka ukugeleza okukhulu kwamalogi.
- Kusuka ku-KDS, idatha ithunyelwa ngamapayipi omlilo ku-Amazon Redshift enezindawo zokugcina izimpahla ezimaphakathi e-Amazon S3.
- Amalogi okusebenza onjiniyela (ulwazi lokususa iphutha, imilayezo yamaphutha, njll.) afomethwe nge-JSON ebukekayo futhi athunyelwa ku-Amazon CloudWatch Logs.
Ukusebenzisana ne-zoo enjalo yezinsizakalo ze-AWS, ufuna ukwazi ukuthi yini eku-arsenal nokuthi ungayisebenzisa kanjani kangcono.
Cabanga nje - unembazo endala, eqinisekisiwe egawula kahle izihlahla futhi ishaye kahle izipikili. Phakathi neminyaka yokusebenza, ufunde ukuyiphatha kahle, ukuhlanganisa i-doghouse, amashede ambalwa futhi mhlawumbe ngisho neqhugwane. Kwesinye isikhathi kuvela ubunzima; ngokwesibonelo, ukuqinisa isikulufu ngembazo akusebenzi ngokushesha ngaso sonke isikhathi, kepha imvamisa kungaxazululwa ngosizo lokubekezela nomama onjalo.
Bese kuvela umakhelwane ocebile eduze, onefu elikhulu lamathuluzi ahlukahlukene: amasaha kagesi, izibhamu zezinzipho, ama-screwdriver futhi uNkulunkulu uyazi ukuthi yini enye. Ukulungele ukuqasha yonke le ngcebo ubusuku nemini. Okufanele ngikwenze? Siyayichitha inketho yokuthatha imbazo siyiphuce njengabantu abangafundile ngepolitiki. Into ehlakaniphe kakhulu ongayenza kungaba ukufunda ukuthi hlobo luni lwamathuluzi akhona, ukuthi bangaphelelisana kanjani emisebenzini eyahlukene, nokuthi banikezwa ngaphansi kwaziphi izimo.
Njengoba lokhu kwakuyisizathu esiyinhloko kimi, ukulungiswa kwahlelwa ngokufanele - ukuthola umhlahlandlela oyisisekelo futhi ngiwufundisise ngokucophelela. Futhi umhlahlandlela onjalo . Le ncwadi ibhalwe kancane yomile, kodwa lokhu akunakwenzeka ukwethusa abantu abafunde i-matan ngokusho kukaFichtenholtz.
Ngiyifunde kusukela ekuqaleni kuye ekupheleni futhi ngicabanga ukuthi ihlangabezana ngokugcwele nenhloso yayo - inikeza umbono omuhle wawo womabili amasevisi ngokwawo kanye nemiqondo ejwayelekile kakhulu okungenzeka kuhlangatshezwane nayo esivivinyweni. Ngaphezu kwalokho, ibhonasi enhle yithuba lokudlula inqubo yokubhalisa eyinqaba ngandlela thize ku-Sybex futhi uphendule yonke imibuzo yokuhlolwa kanye nezivivinyo zokuphrakthiza ezivela encwadini eku-inthanethi.
Iphuzu elibalulekile: Ngifunde ngisebenzisa incwadi evela kuhlelo lwango-2016, kodwa ku-AWS yonke into ishintsha kakhulu, ngakho-ke bheka uhlelo lwakamuva oluzotholakala ngesikhathi sokulungiselela. Isibonelo, imibuzo emayelana nokutholakala nokuqina kwamakilasi ahlukahlukene e-S3 ne-Glacier ivame ukuvela ezivivinyweni zokuhlola, kodwa ezinye izinombolo zishintshile uma kuqhathaniswa no-2016. Ngaphezu kwalokho, ezintsha zengeziwe (isibonelo, INTELLIGENT_TIERING noma ONEZONE_IA).
I-Motif yesibili: "65 shades of orange"
Ukucabanga okushubile kudinga umzamo othile. Kodwa akuyona imfihlo ukuthi abahleli abaningi bathola injabulo ye-masochistic ezinkingeni ezididayo, imibuzo futhi ngezinye izikhathi ngisho nezivivinyo.
Ngicabanga ukuthi lobu bumnandi bufana nokudlala ini? Kuphi? Nini?" noma, ake sithi, umdlalo omuhle we-chess.
Ngalo mqondo, ukuhlolwa kwamanje kwe-AWS Solutions Architect Associate kuhle kakhulu. Nakuba ngesikhathi sokulungiselela, phakathi kwemibuzo yokuhlolwa, ngezikhathi ezithile kwakuba khona “eminyene,” njengokuthi “Mangaki amakheli e-IP anwebekayo ongaba nawo ku-VPC?"Noma"Yini ukutholakala kwe-S3 IA?“, ngesikhathi sokuhlolwa babengekho abantu abanjalo. Eqinisweni, cishe yonke imibuzo engama-65 yayiyinkinga yokuklama okuncane. Nasi isibonelo esivamile esivela emibhalweni esemthethweni:
Uhlelo lokusebenza lwewebhu luvumela amakhasimende ukuthi alayishe ama-oda ebhakedeni le-S3. Imicimbi ye-Amazon S3 ewumphumela ivula umsebenzi we-Lambda ofaka umlayezo kulayini we-SQS. Isenzakalo esisodwa se-EC2 sifunda imilayezo evela kulayini, siyicubungule, futhi siyigcine kuthebula le-DynamoDB elihlukaniswe nge-ID ye-oda ehlukile. Ngenyanga ezayo ithrafikhi kulindeleke ukuthi inyuke ngenani elingu-10 kanti iSolutions Architect ibuyekeza ukwakheka kwezinkinga ezingaba khona zokukala. Iyiphi ingxenye KAKHULU okungenzeka idinge ukwakhiwa kabusha ukuze ikwazi ukukala ukuze ihambisane nethrafikhi entsha?
A. Umsebenzi we-Lambda B. SQS ulayini C. EC2 isibonelo D. DynamoDB ithebula
Ngokwazi kwami, inguqulo yangaphambilini yokuhlolwa iqukethe imibuzo engama-55 futhi yabelwa imizuzu engama-80. Ngokusobala, benze umsebenzi omuhle kuwo: manje sekunemibuzo engama-65 nemizuzu eyi-130 kubo. Isikhathi sombuzo ngamunye sinyukile, kodwa cishe ayikho imibuzo edlulayo. Kwakudingeka ngicabange ngakunye, ngezinye izikhathi isikhathi esingaphezu kwemizuzu emibili.
Ngendlela, kunesiphetho esisebenzayo kulokhu. Ngokujwayelekile iqhinga lokuwina wukudlula yonke imibuzo ngokushesha bese uphendula okuphendulwayo ngokushesha. Endabeni ye-SAA-C01, lokhu ngokuvamile akusebenzi, kuzodingeka ukuthi umaka cishe yonke imibuzo ngamabhokisi okuhlola, ngaphandle kwalokho kunengozi yokunganaki imininingwane ethile bese uphendula ngokungalungile. Ngigcine ngokuphendula, ngichitha umzuzu noma amabili embuzweni ngamunye, bese ngibuyela kuleyo ebihlatshwe umkhosi futhi ngachitha imizuzu engama-20 esele kuyo.
Isisusa sesithathu: “Ukube intsha ibiyazi, ukube ukuguga bekungakwazi”
Njengoba nazi, esinye sezizathu ezivame kakhulu zokwenqaba okutholwe abahleli bezinhlelo abangaphezu kweminyaka engama-40 amandla abo okufunda ancishisiwe uma kuqhathaniswa nentsha.
Khonamanjalo, kunomuzwa wokuthi kwezinye izindawo ikhono lami lokufunda liye lenyuka ngisho uma kuqhathaniswa neminyaka yami yokufunda - ngenxa yokuphikelela okukhulu nolwazi, okungivumela ukuthi ngisebenzise izifaniso ezijwayelekile ezindabeni engingazazi.
Kodwa ukuzwa kungase kukhohlise; umbandela obalulekile uyadingeka. Ingabe akuyona inketho yokulungiselela ukuhlolwa futhi uphumelele?
Ngicabanga ukuthi ukuhlolwa kube yimpumelelo. Ngazilungiselela ngedwa futhi amalungiselelo ahamba kahle impela. Yebo, yebo, izikhathi ezimbalwa ngalala ku-hammock ngenkathi ngifunda incwadi, kodwa lokhu kungenzeka kunoma ubani.
Manje kunesitifiketi namaphuzu ahloniphekile okuhlolwa njengophawu lwesibhamu emaflaskini.
Hhayi-ke, okuncane mayelana nokuthi kungaba yini ugqozi, kodwa bekungenakwenzeka ukuthi kube sesimweni sami.
Akusona isisusa sokuqala: “Iklabishi”
Kukhona abafuna ukwazi mayelana nokuthi yiziphi izitifiketi ezikhokhelwa kakhulu emhlabeni, futhi i-AWS SAA isendaweni yesine ehloniphekile
Kodwa, okokuqala, iyini imbangela futhi uyini umphumela? Ngisola ukuthi abafana benza imali enhle
ngenxa yamakhono athile, futhi lawa makhono afanayo asiza ukuphasa isitifiketi. Okwesibili, ngihlushwa ukungabaza okungacacile kokuthi umuntu uzokhokhelwa u-$130 K ngonyaka ngaphandle kwase-USA, ngisho noma eqinisekisiwe kusukela ekhanda kuye ozwaneni.
Futhi ngokuvamile, njengoba wazi, ngemva kokwanelisa amazinga aphansi ephiramidi, iholo liyayeka ukuba yisici esiyinhloko.
Akusona isisusa sesibili: “Izidingo zenkampani”
Izinkampani zingase zikhuthaze noma zidinge ngisho nezitifiketi (ikakhulukazi uma zidingeka kubambiswano, njengobulungu be-AWS APN esimweni se-Amazon).
Kodwa kithi, kukhiqizwa umkhiqizo ozimele, futhi sizama nokugwema ukukhiya umthengisi. Ngakho akekho odinga izitifiketi. Bazokuncoma futhi bakhokhele ukuhlolwa ngokuqaphela imizamo ethile - konke lokho okusemthethweni.
Akusona isisusa sesithathu: “Ukuqashwa”
Mhlawumbe ukuba nezitifiketi kuzoba usizo oluqondile lokuthola umsebenzi, zonke ezinye izinto ziyalingana. Kodwa anginazo izinhlelo zokushintsha umsebenzi. Kuyathakazelisa ukusebenza emkhiqizweni oyinkimbinkimbi osebenzisa izindlela eziningi ezintsha nezinsiza ze-AWS. Konke lokhu kwanele endaweni yamanje.
Cha, kunjalo, kunamacala ahlukene: eminyakeni engu-23 ngise-IT ngashintsha umsebenzi izikhathi ezingu-5. Akulona iqiniso ukuthi ngeke ngiphinde ngishintshe uma ngihlala eminye iminyaka engu-20. Kodwa uma bengihlula, sizobe khala.
Iwusizo
Sengiphetha, ngizosho ezinye izinto ezimbalwa engizisebenzise ngilungiselela ukuhlolwa futhi “njengesilola isaha”:
- Izifundo zevidiyo и . Okwakamuva, bathi, kuhle kakhulu uma uthenga ukubhalisa nokufinyelela kuzo zonke izivivinyo zokuzilolonga. Kodwa omunye wemibandela yegeyimu yami bekuwukungasebenzisi nesenti elilodwa ekulungiseleleni; ukuthenga okubhaliselwe akuzange kuhambe kahle nalokhu. Ukwengeza, ngokuvamile ngithola ifomethi yevidiyo ingaminyene kakhulu ngokwenani lolwazi ngeyunithi ngayinye yesikhathi. Kodwa-ke, lapho belungiselela i-SA Professional, cishe ngizobhalisela ukubhalisa.
- Amathani wemibhalo esemthethweni ye-Amazon, kufaka phakathi ama-FAQ namaPhepha amhlophe.
- Yebo, into yokugcina, kodwa ebalulekile - . Ngibathole ezinsukwini ezimbalwa ngaphambi kokuhlolwa futhi ngizilolonge kahle. Akukho ongakufunda lapho, kodwa ukuxhumana okuku-inthanethi namazwana ezimpendulo kuhle.
