- Ukwakhiwa kwezinsizakalo ezincane kuhlukanisa uhlelo lokusebenza lube yizinsizakalo ezincane, ezizimele ezihambisana nezizinda zebhizinisi.
- Amaphethini afana ne-Database per Microservice, i-Saga, i-API Gateway, i-CQRS, kanye ne-Clean Architecture avumela ukuphathwa kwedatha, ukuthengiselana, kanye nokuxhumana.
- Ama-container, ama-Kubernetes, i-CI/CD, ukubonwa okuthuthukisiwe, kanye nokuphepha kwe-Zero Trust kuyizinto ezibalulekile zobuchwepheshe zokusebenzisa izinsizakalo ezincane ekukhiqizeni.
- Le ndlela inikeza ukuguquguquka nokukhula, kodwa iletha ubunzima futhi idinga ubuchwepheshe ezinhlelweni ezisatshalalisiwe kanye nesiko eliqinile le-DevOps.
Ukwakhiwa kwe-Microservices sekuyindlela ejwayelekile yokwakha izinhlelo zokusebenza zamafu zesimanje: ezikwazi ukukhuliswa, eziqinile, futhi ezilula ukuzishintsha. Kunokuba nje kube "icebo" lokuphula i-monolith, kusho izinguquko ezinkulu endleleni esiklama, esithuthukisa, esisebenzisa, futhi esisebenzisa ngayo isofthiwe.
Kulesi sihloko, sizobheka ngokujulile nangokusebenziseka kakhulu ukuthi ukwakheka kwe-microservices kanye nokwakhiwa kwe-decentralized kuyini , ukuthi izinzuzo kanye nokungalungi kwazo kwangempela kuyini, yiziphi izingxenye ezenza kube nokwenzeka, ukuthi zihlobana kanjani namaphethini afana ne-MVC noma i-Clean Architecture, iyiphi indima edlalwa yi-database kanye neziqukathi, nokuthi yimaphi amaphethini okuklama kanye nokusabalalisa ayisihluthulelo sokuvimbela ukusungulwa ukuthi kube yisiphithiphithi esingenakulungiseka.
Kuyini ngempela ukwakheka kwezinsizakalo ezincane?
Uma sikhuluma ngama-microservices, sibhekisela endleleni yokuthuthukisa lapho uhlelo lokusebenza luhlukaniswe khona lube yizinsizakalo ezincane, ezizimele, nezikhethekile , ngayinye inomthwalo wemfanelo webhizinisi ochazwe ngokucacile. Lezi zinsizakalo zivame ukuxhumana ngama-API alula (i-REST, i-gRPC, imiyalezo, imicimbi), zisetshenziswa ngokuzimela, futhi zivame ukuphatha isitoreji sazo sedatha.
I-microservice empeleni iyisici sesofthiwe esizisebenzelayo, esilawulwa yithimba elincane elinomthwalo wemfanelo womjikelezo wayo wokuphila: ukuklama, ukuthuthukisa, ukuhlola, ukusabalalisa, ukubonwa, kanye nokugcinwa. Lo mqondo "womkhiqizo, hhayi iphrojekthi" uyisisekelo semodeli: isevisi ayilethwa futhi ayikhohliwe; iyakhuliswa futhi ithuthukiswa njalo.
Ngokungafani nokwakhiwa kwe-monolithic yakudala, lapho zonke izici zisebenza ndawonye enqubweni eyodwa kanye nesizindalwazi esisodwa , ama-microservices akhetha ukuhlukanisa: isevisi ngayinye ingabhalwa ngolimi oluhlukile, isebenzise ubuchwepheshe bayo besizindalwazi futhi ihunyushwe ngesivinini sayo, ngaphandle kokudonsa lonke uhlelo kanye noshintsho ngalunye.
Le modeli ifanelana kahle nemikhuba ye-DevOps , ukuhlanganiswa okuqhubekayo, kanye nokulethwa okuqhubekayo , njengoba ivumela imijikelezo yokuthunyelwa okusheshayo, okuvamile, kanye nengozi ephansi. Kodwa-ke, yethula izinga elisha lobunzima ekuxhumaneni, idatha, ukubonwa, kanye nokuphatha okumele kuphathwe ngempumelelo.
Izici ezibalulekile zezinsizakalo ezincane
Uhlelo olusekelwe kuma-microservices luvame ukuba nezici eziningi ezifanayo, yize inhlangano ngayinye izisebenzisa ngendlela yayo :
Okokuqala, izingxenye zohlelo lokusebenza zisetshenziswa njengezinsizakalo ezizimele ezisebenza njengamayunithi okufakwa kanye nokufakwa esikhundleni okuhlukanisiwe . Esikhundleni sama-library angaphakathi kwememori, izinsizakalo zixhumana kusetshenziswa izingcingo ze-HTTP/REST, i-gRPC, noma imiyalezo, okwethula ukubambezeleka kodwa kunciphisa ukuhlanganiswa.
Ukuhlukaniswa kusekelwe emakhonweni ebhizinisi , hhayi ezingqimbeni zobuchwepheshe. Isevisi ngayinye ihambisana nesizinda noma umongo ochaziwe (isb., abasebenzisi, ikhathalogi, ama-oda, izinkokhelo) futhi ihlanganisa yonke i-logic edingekayo: i-API, i-logic yesizinda, ukufinyelela kwedatha, kanye nokuhlanganiswa komuntu wesithathu.
Kuthathwa umqondo wokuthi "imikhiqizo, hhayi amaphrojekthi" : iqembu elilodwa elihlanganisa imikhakha eminingi (i-backend, i-frontend, i-QA, i-DevOps) linesibopho se-microservice kuyo yonke impilo yalo. Lokhu kukhuthaza ubunikazi kusukela ekuqaleni kuya ekugcineni, kusheshise ukulethwa, futhi kugweme ukudluliswa okungapheli phakathi kweminyango.
Ngokuphathelene nesitayela sokuhlanganiswa, isimiso esithi "ama-endpoints ahlakaniphile kanye namapayipi alula" sivame ukuthandwa . I-logic yebhizinisi ihlala ezinsizeni, kuyilapho ingqalasizinda yokuxhumana (i-HTTP, imigqa, abadayisi bemicimbi) igcinwa ilula ngangokunokwenzeka, igwema ukuhlelwa okuyinkimbinkimbi kakhulu okuhambisana nezinqubo ezisindayo futhi ithanda izinhlelo eziqhutshwa yimicimbi.
Esinye isici esibalulekile ukuphathwa kobuchwepheshe ngendlela ehlukaniswe ngokwezigaba : ithimba ngalinye lingakhetha ulimi, uhlaka, kanye nohlobo lwedathabheyisi olufanelana kahle nezidingo zalo, inqobo nje uma linamathela ezindinganisweni ezincane zokusika (ukuphepha, ukuloba, ukubonwa, izinkontileka ze-API). Le nkululeko ivumela ukwenziwa ngcono kokusebenza, izindleko, kanye nokukhiqiza ngokwesisekelo secala ngalinye.
Ukuphathwa kwedatha okuhlukaniswe kanye nephethini yedathabheyisi ngayinye ye-Microservice
Esinye sezinqumo ezibucayi kakhulu lapho uthuthela kule ndlela ukuthi ungaphatha kanjani idatha. Iphethini evame kakhulu yi- Database per Microservice : isevisi ngayinye inesizindalwazi sayo futhi iphatha, okungaba isibonelo sobuchwepheshe obufanayo nobabanye noma into ehluke ngokuphelele.
Le ndlela ithuthukisa ukuzimela ngoba ushintsho ngalunye lweskimu luthinta kuphela isevisi enaleyo datha , lunciphisa izithiyo kuseva eyodwa yedatha, futhi lukhuthaza ukuqhubeka kwe-polyglot: isevisi eyodwa ingasebenzisa i-PostgreSQL, enye i-MongoDB, enye i-cache ku- Redis , kanti enye injini yokusesha efana ne-Elasticsearch yemibuzo eyinkimbinkimbi kanye nokuhlaziywa kombhalo.
Isibonelo, kusayithi le-e-commerce singaba nesevisi yomsebenzisi egcina idatha yayo yobudlelwano ku-PostgreSQL , isevisi yekhathalogi esebenzisa isizindalwazi se-NoSQL ukwenza imodeli yemikhiqizo eguquguqukayo kakhulu, isevisi ye-oda enesinye isizindalwazi sobudlelwano esilungiselelwe ukuthengiselana, isevisi yenqola yokuthenga esekelwa yi-Redis yedatha yesikhashana, kanye nesevisi yokusesha nge-Elasticsearch yemibuzo eyinkimbinkimbi kanye nokuhlaziywa kombhalo.
Okubi ukuthi ukuthengiselana kwe-ACID okusatshalalisiwe kuba yinto engasebenzi . Esikhundleni sokuthengiselana okukodwa okukhulu okuthinta amathebula amaningi, ukuvumelana ekugcineni, imicimbi yesizinda, kanye namaphethini afana ne-Saga kuvame ukusetshenziselwa ukuhlanganisa izinguquko phakathi kwezinsizakalo, ukwamukela ukuthi izinsizakalo ezahlukene zingaba nezimo ezahlukene isikhathi esifushane.
Ukuze ufinyelele idatha yesevisi ethile, esikhundleni sokuya "ngemuva" kwedatha yayo, kunconywa ukusebenzisa amaphethini afana ne-API Composition (isevisi ihlanganisa idatha ngokubiza izinsizakalo eziningana ezizimele) noma i-CQRS (ehlukanisa ukufunda nokubhala nokugcina ukubikezela kokufunda kuphela kubuyekezwa yimicimbi).
Ukuhlelwa kwe-Orchestra vs. Choreography kanye ne-Saga Pattern
Uma inqubo yebhizinisi ihlanganisa izinsizakalo eziningana (isib. ukubhaliswa kwamakhasimende, ukudalwa kwe-akhawunti yokwethembeka, ukulethwa kwezinsiza zokwamukela, kanye ne-imeyili ), kunezindlela ezimbili ezinkulu zokuxhumanisa: ukuhlelwa kwemisebenzi kanye nokuhlelwa kwemisebenzi.
Ngendlela yokuqondisa , kukhona ingxenye ephakathi (insizakalo yokuqondisa noma "yomxhumanisi") eyazi konke ukugeleza: ibiza insizakalo yamaphuzu, bese kuba insizakalo yeposi, bese kuba insizakalo ye-imeyili, ilawula izimo eziphakathi, futhi iphathe amaphutha. Kulula ukuyilandela, kodwa ivame ukugxila kakhulu ekucabangeni bese iba "isilo esiphakathi."
Ngokuphambene nalokho, ngendlela ehlelwe ngendlela yokudweba , inqubo isekelwe ezenzakalweni ezishicilelwa futhi zisetshenziswe yizinsizakalo . Insizakalo yamakhasimende ikhipha umcimbi "odalwe ngamakhasimende"; insizakalo yokwethembeka iyawulalela futhi inikeze amaphuzu; insizakalo yeposi iyalalela futhi ikhiqize iposi; insizakalo ye-imeyili ithumela umlayezo wokwamukela. Insizakalo ngayinye iyazi ukuthi yenzeni uma ibuka imicimbi ethile, ngaphandle kwesici esiyinhloko esilawula umdanso.
Iphethini ye -Saga isebenzisa le mibono ukuphatha ukuthengiselana okusatshalalisiwe. I-Saga iqukethe uchungechunge lwemisebenzi yasendaweni kuzo zonke izinsizakalo ezahlukene, futhi uma kwenzeka iphutha, uchungechunge lwezenzo zokunxephezela ezihlehlisa (noma ezinciphisa) izinguquko zangaphambilini. Ama-Saga angasetshenziswa ngendlela ehlelekile (ingxenye eyodwa iqondisa ukugeleza konke) noma ngendlela ehleliwe (insizakalo ngayinye isabela ezenzakalweni futhi ishicilele ezintsha).
I-choreography ivame ukufaneleka kangcono kwezakhiwo zezinsizakalo ezincane ezisatshalaliswe kakhulu, eziqhutshwa yimicimbi, kodwa idinga ukubonwa okuhle kakhulu nokuqapha ukuhamba kwebhizinisi ukuze kwaziwe ukuthi kwenzekeni esinyathelweni ngasinye futhi kutholakale ukungahambisani noma ukwehluleka okuyingxenye.
Amaphethini okubekezelela amaphutha kanye nokuqina
Kuhlelo olusatshalaliswe, kubalulekile ukwamukela ukuthi noma yiluphi ucingo lwesevisi lungahluleka, luthathe isikhathi eside kakhulu, noma lubuyise amaphutha ngezikhathi ezithile . Ukungazinaki lokhu kuyindlela yokwehluleka okukhulu kanye nokuphazamiseka komhlaba wonke.
Ukuze kuncishiswe lezi zingozi, kusetshenziswa amaphethini amaningana okuqina, aqala ngokuphelelwa yisikhathi okuphezulu kuzo zonke izingcingo ezikude. Akekho ofuna izintambo zivinjwe unomphela zilinde ukuvalwa kwesevisi; lapho ukuphela kwesikhathi kuphelelwa yisikhathi, iklayenti lingakhetha ukuzama futhi, limise umsebenzi ngokulandelana kwesikhathi, noma lehlise ukusebenza.
Iphethini ye -circuit breaker yengeza ungqimba olwengeziwe lokuvikela: uma iklayenti libona ukuthi iphesenti elikhulu lezingcingo eziya kusevisi liyahluleka, "livula isekethe" bese liyeka ukuzama ukubiza leyo sevisi isikhashana, libuyisele ukwehluleka okusheshayo noma izimpendulo eziwohlokile. Ngemva kwesikhathi esithile, livumela izingcingo ezimbalwa zokuhlola (isimo esivulekile kancane) futhi, uma lezi ziphumelela futhi, livala isekethe futhi.
Kuvamile futhi ukuklama izindawo ezingangeni manzi , kokubili ezinengqondo nezingokwenyama, ukuze zivimbele umonakalo: ama-pod amaningi ngesevisi ngayinye, imishini eminingi, noma ngisho nezifunda eziningi, ukuze ukwehluleka kwendawo kungawi phansi lonke uhlelo. Ukusetshenziswa kwamasu anjengokunciphisa izinga noma imigqa yokulinganisa umthwalo kusiza ukuvimbela ukunyuka okungazelelwe ekukhubazeni izinsizakalo ezibalulekile.
Konke lokhu kusekelwa amamojula okuqina angasetshenziswa kabusha (isibonelo, imitapo yolwazi efana ne-Resilience4j ehlanganiswe nezinhlaka ezifana ne-Spring Cloud) ezikuvumela ukuthi ulungiselele izinqubomgomo zokuzama kabusha, imikhawulo yesicelo, ama-circuit breakers kanye nokuphathwa kwamaphutha ngendlela ephakathi nendawo nengaguquguquki kuzo zonke izinsizakalo.
Izingxenye ezijwayelekile zokwakheka kwezinsizakalo ezincane
Ngaphezu kwezinsizakalo zebhizinisi ngokwazo, ukwakheka kwezinsizakalo ezincane ezivuthiwe kufaka uchungechunge lwezingxenye eziyisisekelo zepulatifomu ukuqinisekisa ukuthi konke kusebenza ngokuthembeka :
Ngakolunye uhlangothi kukhona i- orchestrator noma ipulatifomu yeziqukathi (ngokuvamile i-Kubernetes), enesibopho sokuhlela nokusebenzisa iziqukathi, ukukala amakhophi, ukuqala kabusha izinsizakalo ezihlulekile kanye nokuhlinzeka ngokutholwa kwensizakalo kanye nezindlela zokulinganisa umthwalo wangaphakathi; kuyalulekwa ukusebenzisa izinyathelo zokuphepha kweziqukathi kule ngqalasizinda.
Emaphethelweni okwakhiwa kwezakhiwo kuvela i -API Gateway , esebenza njengendawo eyodwa yokungena yamakhasimende angaphandle: ihambisa izicelo ziye kusevisi encane efanele, iphoqelele ukuqinisekiswa nokugunyazwa, ingeza noma iqinisekise izihloko zokuphepha, ilawula ama-quota, isebenza njengommeleli we-TLS, futhi ezimweni eziningi, ihlanganisa izimpendulo.
Ngokuxhumana okungenazo zonke izindlela , kusetshenziswa amapulatifomu okuthumela imiyalezo nokusakaza njenge-Apache Kafka noma i-Azure Service Bus, asekela amaphethini okushicilela nokubhalisa, imigqa yemisebenzi, imicimbi yesizinda, kanye nezakhiwo eziqhutshwa yimicimbi ezikhula ngokushesha.
Ukuqaphela kungenye into ebalulekile: amalogi ahlanganisiwe, amamethrikhi ohlelo lokusebenza, ukulandelwa okusatshalaliswa, kanye nokuqapha kwesikhathi sangempela kusenza siqonde ukuthi kwenzekani ohlelweni olunezinsizakalo eziningi noma ezingamakhulu. Izinhlaka ezifana ne-OpenTelemetry kanye nemibhobho yokuqoqwa nokuhlaziywa (enabaqoqi abazinikele) manje sezibalulekile.
Okokugcina, ukuphathwa kokucushwa okuhlanganisiwe kanye nemojuli yokuphepha (amathokheni okufinyelela, i-mTLS phakathi kwezinsizakalo, ukulawula ukufinyelela okusekelwe ezindimeni, ukuphathwa okuyimfihlo) kuqedela isithombe. Ukucushwa kukhishwe ngaphandle kwekhodi ukuze izinto ezifanayo zisetshenziswe ezindaweni eziningi ngokushintsha amapharamitha angaphandle kuphela.
Amaphethini okwakha nokuklama kuma-microservices
Ukuze ugweme ukusungula kabusha isondo (nokuwela emaphethini aphikisanayo), kubalulekile ukuthembela kumaphethini okwakha nokuklama abonakalise ukuthi asebenza kahle ezindaweni ezisatshalalisiwe :
Esigabeni sokumodela, iphethini ye -Decompose by Subdomain iyagqama , ihlobene kakhulu nomklamo oqhutshwa yisizinda (i-DDD). Umqondo uwukuhlonza ama-subdomain achazwe ngokucacile kanye nezimo (abasebenzisi, ama-oda, ukukhokhisa, izinto zokuhamba, njll.) bese uwabela ama-microservices ahambisana naleyo mingcele, ugweme izinsizakalo ezinkulu kakhulu noma ezincane ngendlela exakile.
Ngokuxhumana okuhambisanayo, kusetshenziswa iphethini yokucela inqubo ekude , esetshenziswa nge-REST, gRPC, GraphQL, noma i-WebSockets. Kunconywa ukusebenzisa indlela ye-API-First, kusetshenziswa izinkontileka ezisemthethweni (i-OpenAPI ye-REST, i-gRPC IDL, noma ama-GraphQL schemas) ukuklama isikhombimsebenzisi kuqala bese kukhiqiza noma kulungisa ikhodi.
Uma kudingeka ukuxhumana okungenazo izinsiza, kusetshenziswa iphethini ye-Messaging , ngokusekelwe ezenzakalweni umkhiqizi azithumela kumthengisi futhi abathengi abaningi abangazicubungula ngejubane labo. Ukuchaza izinkontileka zemicimbi nge-AsyncAPI kuhambisana kahle lapha, ngendlela i-OpenAPI esetshenziswa ngayo emhlabeni we-REST.
Emkhakheni wokufinyelela idatha, ngaphezu kwe-Database per Microservice, i-CQRS (Command Query Responsibility Segregation) iba yinto ebalulekile : ukuhlukanisa imodeli yokubhala (imiyalo) kumodeli yokufunda (imibuzo), kusetshenziswa amaphrojektha kanye nemicimbi ukugcina ukubukwa kokufunda kuphela okulungiselelwe ukusesha kuvumelaniswa.
Ukuze kuvezwe ama-microservices kumakhasimende angaphandle, iphethini ye -API Gateway ihlanganisa ukufinyelela, kuyilapho uhlobo olufana ne -Backend for Frontends (BFF) ludala ama-API athile ohlobo ngalunye lweklayenti (iwebhu, iselula, izinhlelo zokusebenza zangaphakathi) ezihlanganisa futhi zivumelanise idatha ngokwezidingo zesixhumi esibonakalayo ngasinye.
Ubudlelwano ne-MVC, ukwakheka okuhlanzekile kanye namaphethini akudala
Kumaphrojekthi amaningi, indaba iqala ngohlelo lokusebenza olulodwa olusekelwe ku-MVC (Model-View-Controller): abalawuli bewebhu abaphatha izicelo, amamodeli esizinda ahlanganiswe ngokuqinile kusizindalwazi esisodwa, kanye nemibono evezwe kuseva.
Iphethini ye-MVC ihlala iwusizo ngaphakathi kwe-microservice ngayinye eveza i-API noma isikhombimsebenzisi sewebhu (isibonelo, ngezinhlaka ezifana ne-Flask ku-Python ), kodwa akuseyona isakhiwo somhlaba wonke sohlelo lokusebenza lonke . Umkhuba wamanje uwukuhlukanisa i-frontend (ama-SPA, izinhlelo zokusebenza zeselula) bese usebenzisa izinhlaka zesimanje ezisebenzisa ama-microservice API, okushiya iphethini ye-MVC yakudala njengemininingwane yangaphakathi uma isasetshenziswa.
I-Clean Architecture ilungele kakhulu ama-microservices ngoba ikhuthaza izendlalelo ezichazwe kahle kanye nokuxhomekeka okuqondiswe kusizinda: izinhlangano kanye nezimo zokusetshenziswa ku-core, ama-adapter esibonakalayo (abalawuli, abethuli, amasango okuphikelela) ngaphandle, kanye nezinhlaka (izizindalwazi, i-HTTP, imiyalezo) emaphethelweni.
Ukusebenzisa lezi zimiso ngaphakathi kwe-microservice kusenza sikwazi ukuvikela i-logic yebhizinisi emininingwaneni yobuchwepheshe : singashintsha i-database, uhlaka lwewebhu, noma umhlinzeki wemiyalezo ngaphandle kokubhala kabusha umongo wesevisi. Ngaphezu kwalokho, kwenza kube lula kakhulu ukuhlolwa kweyunithi nokuhlanganiswa.
Amaphethini okuklama afana ne-SOLID, ukuhlukaniswa kwemithwalo yemfanelo, ukufakwa kokuxhomekeka, kanye nezimiso zekhodi ezilula zisasebenza ngendlela efanayo; manje zisetshenziswa kuphela ngaphakathi komongo omncane wensizakalo ngayinye encane, okwenza kube lula ukugcina ikhodi ihlanzekile esikhathini eside.
Ukuzenzakalela, i-CI/CD, kanye nokufakwa ezitsheni kanye ne-serverless
Ukwakhiwa kwe-Microservices akunangqondo ngaphandle kokuzenzakalela okunamandla komjikelezo wokuphila wonke ezindaweni ezihlala efwini . Ngezinsizakalo eziningi, ukuthunyelwa ngesandla kuyindlela yokudala inhlekelele.
Amaqembu ngokuvamile asungula amapayipi okuhlanganiswa okuqhubekayo kanye nokulethwa okuqhubekayo (CI/CD) , avame ukusekelwa yi -GitOps , ahlanganisa ikhodi, aqhuba izivivinyo, akhiqize izithombe zesitsha, asebenzise ukufuduka kwedatha (uma kufaneleka), futhi asebenzise izinsizakalo ngendlela ephindaphindwayo, elawulwayo, nelandelekayo.
Iphethini yokusabalalisa ebanzi kakhulu "ukufaka isevisi njengesitsha ," ukupakisha isevisi encane ngayinye esithombeni (isibonelo, i-Docker) bese uvumela i-Kubernetes noma omunye umhleli wezinhlelo ukuthi aphathe ukukopisha, ukukala, kanye nezibuyekezo. Lokhu kuvumela ukusetshenziswa kwezinsiza kusebenza kahle kanye nokufakwa okusheshayo nokungaguquguquki.
Ngaphezu kwalokhu, amaphethini epulatifomu afana ne -service mesh (Istio, Linkerd, njll.) angasetshenziswa, okwengeza amakhono okuhambisa athuthukisiwe, izinqubomgomo zokuphepha ze-mTLS, ukubonwa okuningiliziwe, kanye nokusatshalaliswa kwethrafikhi phakathi kwezinguqulo (ukukhishwa kwe-canary, okuluhlaza okwesibhakabhaka) ngaphandle kokuthinta ikhodi yesevisi.
Ezimweni ezithile, ikakhulukazi emisebenzini ethile noma eqhutshwa yimicimbi, ukuthunyelwa kwe-serverless kuyasetshenziswa : imisebenzi esebenza ngokufunwa (isibonelo, i-AWS Lambda) ehlelwe yizinsizakalo ezifana ne-API Gateway, imigqa, imifudlana, noma abahleli. Nakuba kungezona zonke izinto ezidinga ukungabi ne-server, ngokuvamile kufaneleka kahle kuma-microservices amancane kakhulu futhi anwebeka kakhulu.
Ukuphepha, ukubonwa, kanye nokuhlolwa ezinhlelweni ezisatshalalisiwe
Ukuphepha kuma-microservices kuncike kusimiso se-Zero Trust: akekho othemba noma ubani ngokuzenzakalelayo . Lokhu kuhilela ukuqinisekiswa okuqinile nge-API Gateway (OAuth2, OIDC), ukukhishwa kwamathokheni (isb., i-JWT) ahamba nesicelo ngasinye, ukugunyazwa kwendawo kusevisi ngayinye, kanye nokubethela ithrafikhi yesevisi kuya kusevisi kusetshenziswa i-mTLS.
Iphethini ye -Access Token iyifingqa kahle le ndlela: isango liqinisekisa iziqinisekiso zeklayenti, likhiqize ithokheni enomongo wokuphepha (ubuwena, izindima, izikophu) bese liyithumela kuma-microservices, ayisebenzisela ukwenza izinqumo zokugunyazwa ngaphandle kokugcina amaphasiwedi noma i-logic yokuqinisekisa yangaphakathi.
Ngokuphathelene nokubonakala, amaphethini amaningana ahlanganisiwe: Ama-Application Metrics (ama-metrics obuchwepheshe kanye nebhizinisi ngesevisi ngayinye), i-Audit Logging (ama-log okuhlola ezenzo zomsebenzisi), i-Distributed Tracing (kulandela isicelo ngezinsizakalo eziningi), i-Exception Tracking (izinhlelo zokuphatha amaphutha ezihlanganisiwe), i-Health Check API (i-endpoints state) kanye ne -Log Aggregation (ukuhlanganiswa kwama-log epulatifomu evamile).
Konke lokhu kuvumela ukutholakala kwezimo ezingavamile, kunciphisa izikhathi zokuxilonga , futhi kunikeze ukuqonda ukuthi uhlelo luziphatha kanjani ngaphansi kwemithwalo yangempela. Ngaphandle kokubonwa okuhle, uhlelo lwe-microservices luba ibhokisi elimnyama cishe okungenakwenzeka ukusebenza.
Emkhakheni wokuhlola, ngaphezu kokuhlolwa kweyunithi yakudala, amaphethini afana ne -Service Integration Contract Test (okuqinisekisa ukuthi umhlinzeki nomthengi bayayihlonipha inkontileka efanayo ye-API) kanye ne -Service Component Test (ukusebenzisa isevisi ngokuhlukana kusetshenziswa izingcezu zokuxhomekeka kwangaphandle) ayafaneleka, okunciphisa ukuncika ekuhlolweni okubuthakathaka nokuhamba kancane kokuphela.
Okokugcina, isiko elivuthiwe le-DevOps kanye nomkhuba wobunjiniyela be-chaos (ukufaka ukwehluleka okulawulwayo ukuqinisekisa ukuqina kwesakhiwo) kusiza ukuqinisekisa ukuthi uhlelo luziphatha kahle lapho izinto zihamba kabi, okuyinto eyenzeka njalo ekukhiqizeni ngokushesha noma kamuva.
Izinzuzo, ukungalungi, kanye nezindlela zokwamukelwa
Izinzuzo eziyinhloko zezinsizakalo ezincane zigxile ekuqineni nasekukhuleni: amaqembu amancane nazimele, ukuthunyelwa njalo ngaphandle kokumisa uhlelo lokusebenza lonke, ukukalwa okuzimele kwendawo ngayinye yokusebenza, inkululeko yezobuchwepheshe ngensizakalo ngayinye, kanye nokuqina okukhulu ngenxa yokuhlukaniswa kwamaphutha.
Ziphinde zikhuthaze ukusetshenziswa kabusha kwemisebenzi ehlanganiswe kahle (insizakalo yokukhokha, yokuqinisekisa noma yesaziso ingasebenza njengesisekelo esijwayelekile sezixazululo eziningi), inciphise izindleko zezinguquko zasendaweni, futhi ivumele ukuvumelanisa okungcono kwenhlangano (amaqembu) nemodeli yebhizinisi (izizinda nemikhiqizo).
Ngakolunye uhlangothi, ama-microservices aletha ubunzima obungasho lutho : amaphuzu amaningi okwehluleka, ukubambezeleka kwenethiwekhi okwengeziwe, ubunzima obukhulu ekugcineni ukuhambisana kwedatha, izinqubo zokuthunyelwa kanye nokuhlola eziyinkimbinkimbi kakhulu, kanye nesidingo esikhulu kakhulu sokubonakala, ukuzenzekela, kanye namathuluzi okuphatha.
Ngaphezu kwalokho, zidinga amaphrofayili obuchwepheshe anolwazi ezinhlelweni ezisatshalalisiwe , ama-container, ama-Kubernetes, ukuphepha, amaphethini okuhlanganisa, ukuphathwa kwe-API kanye nokwakhiwa kwesizinda, into engatholakali njalo kuwo wonke amaqembu noma izinkampani.
Ngakho-ke, ukwakheka kwezinsizakalo ezincane kunengqondo ikakhulukazi ezinhlanganweni ezine-codebase enkulu, amaqembu amaningi, izinga eliphezulu lokushintsha kokusebenza, kanye nezidingo ezinamandla zokukhula , njengezinkundla ezinkulu zedijithali, i-SaaS eyinkimbinkimbi, noma izinhlelo ezinezithameli ezinkulu. Kuzinhlelo zokusebenza ezincane noma neqembu elincane, i-monolith enhle ye-modular ivame ukuba lula, ishibhile, futhi yanele.
Ukwakhiwa kwe-microservices kumelela intuthuko ebalulekile ekuthuthukisweni kwe-monolithic yendabuko, kodwa uma kuklanywe kahle futhi kulawulwa kahle, kuba ithuluzi elinamandla lokukhulisa izinhlangano, amaqembu, kanye nezinhlelo. Ukusebenzisa amaphethini afana ne-Database per Microservice, Saga, API Gateway, CQRS, Clean Architecture, ukuthunyelwa kwe-container, kanye namapulatifomu aqinile okubuka, kungenzeka ukwakha izixazululo ezihlanganisa ushintsho olusheshayo, ukuqina kokwehluleka, inkululeko yezobuchwepheshe, kanye nokuhambisana okuhle kakhulu nebhizinisi , uma nje izindleko ezengeziwe zobunzima zamukelwa futhi kwenziwa utshalomali ezenzakalelayo, isiko, kanye nemikhuba emihle kakhulu.
