Chiitiko chekugadzirisa sevhisi
Ngatimbofungidzirai kuti isu tinofanirwa kugadzira chaiyo-nguva chiitiko kugadzirisa - sisitimu inoongorora zviito zvemutengi munguva chaiyo uye inogona kumuita iye chipo chakakodzera. Kuti uite basa rakafanana, shandisa architectural pattern inonzi chiitiko-driven architecture (EDA). Hapana yezvino Service Meshes natively inotsigira maitiro akadaro, asi izvi zvakakosha, kunyanya kubhangi!
Zvinoshamisa kuti Remote Procedure Call (RPC) inotsigirwa neshanduro dzese dzeService Mesh, asi hadzina hushamwari neEDA. Nekuti Sevhisi Mesh imhando yemazuva ano yakagovaniswa yekubatanidza, uye EDA yakanyatso dhizaini yekuvaka pateni iyo inokutendera iwe kuti uite zvinhu zvakasarudzika maererano neruzivo rwevatengi.
Yedu Enterprise Service Mesh inofanirwa kugadzirisa dambudziko iri. Pamusoro pezvo, isu tinoda kuona mairi kushandiswa kwekuvimbiswa kuburitswa, kutenderera uye kwakaoma chiitiko kugadzirisa uchishandisa akasiyana mafirita uye matemplate.
Faira yekufambisa sevhisi
Pamusoro peEDA, zvingave zvakanaka kukwanisa kuendesa mafaera: pachiyero cheBusiness, kazhinji chete faira rekubatanidza rinogoneka. Kunyanya, iyo ETL (Extract, Transform, Load) yekuvaka pateni inoshandiswa. Mariri, sekutonga, munhu wese anotsinhanisa mafaera chete: data hombe rinoshandiswa, izvo zvisingakwanisi kusundira mune zvakasiyana zvikumbiro. Iko kugona kwekuzvarwa kutsigira mafaera mu Enterprise Service Mesh inokupa iwe kuchinjika bhizinesi rako raunoda.
Sevhisi yekuimba

Iyi data inogona kuongororwa uchishandisa AI, kudzidza kwemuchina, nezvimwe, uyezve zvimwe zvinhu zvinobatsira zvinogona kuitwa zvichibva pamhedzisiro yekuongorora. Zvingave zvakakodzera kuti upe hutongi hwese iyi network traffic uye mafoni ekushandisa akabatanidzwa muService Mesh kune hungwaru hwekugadzira.
API Gateway Service
Kazhinji, Sevhisi Mesh ine proxies uye masevhisi anotaura kune mumwe nemumwe mukati meiyo yakavimbika perimeter. Asi kunewo kunze counterparties. Zvinodiwa zvemaAPI zvakafumurwa kuboka iri revatengi zvakanyanya kuomarara. Isu tinoparadzanisa basa iri muzvikamu zviviri zvikuru.
- Chengetedzo. Nyaya dzine chekuita neddos, kusagadzikana kweprotocol, maapplication, masisitimu anoshanda, zvichingodaro.
- Scale. Kana huwandu hwemaAPIs anoda kupihwa kune vatengi huchipinda muzviuru kana kunyange mazana ezviuru, panodiwa imwe mhando yechishandiso chekutonga cheseti yeAPI. Iwe unofanirwa kugara uchitarisa iyo API: vangave vari kushanda kana kwete, chimiro chavo, chii chiri kuyerera traffic, ndeapi manhamba, nezvimwe. Iyo API gedhi inofanirwa kubata basa iri ichiita kuti maitiro ese agoneke uye akachengeteka. Nekuda kwechikamu ichi, Enterprise Service Mesh inodzidza kuburitsa zviri nyore mukati nekunze APIs.
Sevhisi yekutsigira kune yakatarwa maprotocol uye data mafomati (AS gedhi)
Parizvino, akawanda Service Mesh mhinduro dzinogona kushanda zvekuzvarwa chete neHTTP uye HTTP2 traffic kana mune yakaderedzwa modhi padanho reTCP/IP. Iyo Enterprise Service Mesh iri kubuda nemamwe akawanda chaiwo ekufambisa data protocol. Mamwe masisitimu anogona kushandisa meseji broker, mamwe akabatanidzwa padanho redatabase. Kana iyo kambani ine SAP, saka inogonawo kushandisa yayo yekubatanidza system. Uyezve, izvi zvese zvinoshanda uye chikamu chakakosha chebhizinesi.
Iwe haugone kungoti: "Ngatisiyei nhaka uye tigadzire masisitimu matsva anogona kushandisa Service Mesh." Kuti ubatanidze masisitimu ese ekare neayo matsva (pane microservice architecture), masisitimu anogona kushandisa Service Mesh achada imwe mhando yeadapter, murevereri, gedhi. Bvumiranai, zvingava zvakanaka kana yakauya mubhokisi pamwe chete nebasa. Iyo AC gedhi inogona kutsigira chero sarudzo yekubatanidza. Chimbofungidzira, iwe unongoisa Enterprise Service Mesh uye yakagadzirira kupindirana nemaprotocol ese aunoda. Iyi nzira yakakosha zvikuru kwatiri.
Aya ndiwo maitiro atinofungidzira vhezheni yekambani yeSevhisi Mesh (Enterprise Service Mesh). Iyo yakatsanangurwa inogadzirisa inogadzirisa akawanda ematambudziko anomuka kana uchiedza kushandisa yakagadzirira-yakagadzirwa-yakavhurika sosi shanduro dzekubatanidza chikuva.
