I-HAProxy 2.0 ifikile, iseva yommeleli ekwalinganisa umthwalo wewebhu

I-HAProxy isimahla kwaye isoftware evulekileyo ebonelela nge-balancer yomthwalo kunye neseva yommeleli yezicelo ze-TCP kunye ne-HTTP ezisasaza izicelo kwiiseva ezininzi.

Kubhaliwe kwi-C kwaye kudume ngokukhawuleza nangokufanelekileyo. Yaqala ukukhutshwa ngoDisemba ka-2001 phantsi kwelayisensi yeGNU / GPL v2. IHAProxy isetyenziswa ziiwebhusayithi ezininzi eziphambili, ezinje ngeGoDaddy, GitHub, iBitbucket, ukugcwala okugcweleyo, iReddit, iSpeedtest.net, iTumblr, iTwitter, kunye neTuenti. Isetyenziswa kwimveliso ye-OpsWorks evela kwiiNkonzo zeWebhu zeAmazon.

I-HAProxy Technologies ibhengeze ukuphela kweveki ephelileyo ukubakho kwenguqulo 2.0 ye-HAProxy. Inkampani ibhengeze ukuba le nguqulo ye-HAProxy izisa uninzi lwezinto ezintsha eziyimfuneko kwimeko yeekhonteyina kunye nelifu, ngelixa ligcina ukusebenza kunye nokuthembeka.

Olu khululo luphucula amanqaku ahlangabezana neemfuno ezizodwa zesikhongozeli kunye neendawo zefu zeHAProxy 2.0 kukukhutshwa kweLTS

Yintoni entsha kwi-HAProxy 2.0?

Kuhlaziyo olutsha, I-HAProxy 2.0 yongeza iseti yamandla eempawu ezintsha ngokupheleleyo eyandisa ngakumbi ukuhambelana kwayo okungenamthungo ngokudityaniswa kuyilo lwala maxesha.

Oku ibandakanya uLuhlu lwe-7 retry, i-Prometheus metrics, ukubeka esweni ukugcwala kweelwimi, kunye ne-gRPC.

Ukongeza kule nguqulo, ikwabonelela nge-HAProxy Kubernetes Ingress isilawuli kunye neHAProxy Data Plane API, ebonelela nge-REST API yanamhlanje yokumisela nokulawula i-HAProxy.

Ukongeza kuloo nto, inkampani ikwabhengeze ukuba ngaphandle kweempawu ezintsha ezibandakanyiweyo kule nguqulo, i-HAProxy 2.0 ivula indlela yohlaziyo olunomdla oluthi, ngenqanaba lokukhululwa elitsha,

Ukucoca kunye nokungena kwilifu

Kule nto intsha, iHAProxy Technologies yazisa ukuba ukumisela i-HAProxy yokusebenza ngokukuko ngoku kulula.

Ukusukela kwinguqulelo 1.8, ukwazile ukuseta "nbthread" ukuyalela ukuvumela i-HAProxy ukuba isebenze kwimisonto emininzi, Ukuvumela ukuba ubusebenzise ngcono oomatshini abaneeprosesa ze-multicore.

Ukuqala ngohlobo lwe-2.0, i-HAProxy ngoku iyayilungisa ngokuzenzekelayo. Iya kuthi kwangoko isete inani lemisonto yomsebenzi ehambelana nenani leekhompyuter zeprosesa ezikhoyo kumatshini.

I-MASQ

I-HAProxy 2.0 ibonelela ngenkxaso epheleleyo kwisakhelo se-RPC umthombo ovulekileyo, gRPC. Inika amandla ukuhanjiswa kwedatha ye-bi-directional, ukufunyanwa komyalezo we-gRPC, kunye nokungena kwe-gRPC.

Umgaqo-nkqubo we-gRPC sisiseko seRPC sanamhlanje, esisebenza ngokusebenzayo esinokusebenza nakweyiphi na imeko.

Usebenzisa i-protocol ye-buffers, unokwenza imiyalezo ngokulandelelana kunye nefomathi esebenzayo ngakumbi kune-JSON.

Ukuqala ukusebenzisa i-gRPC kwi-HAProxy, kufuneka wenze ubumbeko oluqhelekileyo lwe-HTTP / 2 ukusuka ekuqaleni ukuya ekugqibeleni. Ii-ACL ezisemgangathweni ziyanyanzeliswa kwaye zivumela ukuhambelana okusekwe kwindlela. Ngapha koko, kuguqulwe ezimbini ezintsha «protobuf kunye» ungrpc «ziye zaziswa ukuze zikwenze.

Uluhlu 7

Ukunciphisa ixesha lokuphumla kuhlala kubandakanya ukuseta iindlela zokubikezela. Ukusukela ekusekweni kwayo, i-HAProxy ixhase ukuzama ukuphinda unxibelelwano lwe-TCP olungaphumeleliyo ngokubandakanya "ukuphinda ukhethe ukhetho" umyalelo.

Nge-HAProxy 2.0, unokuphinda uzame kwenye iserver 7 yiseva yezicelo ezingaphumelelanga ze-HTTP.

Umyalelo omtsha wokumisela, "zama kwakhona" unokusetyenziswa kwicandelo "lokungagqibeki", "mamela" okanye "umva". Inani lokuphinda uzame lingakhankanywa kusetyenziswa umyalelo "wokuzama kwakhona".

Kubalulekile ukuba uyazi ukuba isicelo sakho siziphatha njani ngovavanyo lwe-7.

Umlawuli wokungena kwi-Kubernetes

Umqhubi wobunjineli omtsha weHAProxy Kubernetes ibonelela ngokuqonda kokusebenza okuphezulu kwizicelo zakho ezibanjelwe eKubernetes.

Ixhasa ukothula umthwalo we-TLS, ukuhambisa umzila we-7, ukunciphisa umda, ukwenza iphepha elimhlophe kunye nokusebenza ngokugqwesileyo eyaziwa ngokuba yi-HAProxy.

Amangenelo anokuqwalaselwa ngezichazi okanye izixhobo zeConfigMap. Kuyenzeka ukuba uchaze iimfihlo zokugcina izatifikethi ze-TLS.

I-HAProxy 2.0 ibonelela ngenkxaso ye-LTS kule misebenzi ingentla, kunye nemisebenzi eyazisiweyo okanye eyandisiweyo ngexesha lenguqulelo 1.9.

Ikwazisa abaguquleli abatsha ekuvumela ukuba uguqule idatha ibe yi-HAProxy kwaye ilandelwe ngokubanzi emva kokukhutshwa. Olu luphononongo nje lwezinto ezininzi eziziswe kwi-HAProxy 2.0.
