Cov hnub so ntev ua ntej, uas txhais tau hais tias yuav muaj sijhawm rov qab los rau koj cov ntawv nyeem tom qab lossis rov nyeem cov ntawv tseem ceeb ntawm lub xyoo dhau mus. Hauv cov ntawv tshaj tawm no, peb tau sau thiab npaj rau koj cov npe ntawm cov ntaub ntawv nthuav dav tshaj plaws los ntawm peb cov blog hauv 2019 thiab peb vam tias lawv yuav muaj txiaj ntsig rau koj.
Lub xyoo dhau los tau nthuav dav thiab muaj txiaj ntsig zoo: cov thev naus laus zis tshiab, kev nrawm tshiab thiab cov kev sib tw tshiab. Txhawm rau pab peb cov neeg nyeem kom muaj kev vam meej, peb tau sim tshaj tawm txog txhua yam kev lag luam tseem ceeb ntawm peb cov blog kom sai li sai tau. Peb cov engineers thiab testers nquag pab peb hauv qhov no, sim tawm cov khoom kho vajtse thiab software tshiab los ntawm lawv cov kev paub dhau los. Tag nrho cov ntaub ntawv khaws tseg thaum kawg tau muab tso ua ke thiab dhau los ua cov khoom rau cov neeg tsim khoom, engineers, cov thawj tswj hwm thiab lwm cov kws tshaj lij. Peb zoo siab los qhia peb cov kev paub dhau los rau koj, thiab peb cia siab tias tsawg kawg qee zaum peb tuaj yeem pab koj xaiv qhov zoo thiab txuag koj lub sijhawm. Ua tsaug rau koj nrog peb!

Serverless ntawm racks
Serverless tsis yog hais txog lub cev tsis muaj servers. Qhov no tsis yog lub thawv killer lossis ib qho kev dhau mus. Qhov no yog ib txoj hauv kev tshiab rau kev tsim cov tshuab hauv huab. Nyob rau hauv tsab xov xwm niaj hnub no peb yuav kov cov architecture ntawm Serverless daim ntaub ntawv, cia saib seb lub luag haujlwm ntawm Serverless muab kev pabcuam thiab cov haujlwm qhib qhov twg ua si. Thaum kawg, cia peb tham txog cov teeb meem ntawm kev siv Serverless.
Ua raws li OpenStack LBaaS tus neeg siv interface
Los ntawm tus sau: "Kuv tau ntsib cov teeb meem tseem ceeb thaum siv cov khoom siv sib npaug ntawm cov neeg siv khoom siv rau huab huab virtual. Qhov no ua rau kuv xav txog lub luag haujlwm ntawm lub frontend, uas kuv xav qhia ua ntej. "
Rau cov neeg tswj hwm qhov system
Los ntawm High Ceph Latency mus rau Kernel Patch siv eBPF / BCC
Linux muaj ntau cov cuab yeej rau kev debugging lub ntsiav thiab cov ntawv thov. Feem ntau ntawm lawv muaj kev cuam tshuam tsis zoo rau daim ntawv thov kev ua haujlwm thiab tsis tuaj yeem siv hauv kev tsim khoom.
Ob peb xyoos dhau los, lwm lub cuab yeej tau tsim - eBPF. Nws ua rau nws muaj peev xwm taug qab cov ntsiav thiab cov neeg siv cov ntawv thov nrog cov nyiaj siv ua haujlwm qis thiab tsis tas yuav tsim kho cov kev pab cuam thiab thauj cov khoom thib peb rau hauv cov ntsiav.
IP-KVM via QEMU
Kev daws teeb meem kev khiav hauj lwm qhov teeb meem khau raj ntawm servers yam tsis muaj KVM tsis yog ib txoj haujlwm yooj yim. Peb tsim KVM-dhau-IP rau peb tus kheej ntawm cov duab rov qab thiab lub tshuab virtual.
Yog tias muaj teeb meem tshwm sim nrog lub operating system ntawm cov chaw taws teeb server, tus thawj coj rub tawm cov duab rov qab thiab ua haujlwm tsim nyog. Txoj kev no ua haujlwm zoo heev thaum paub txog qhov ua rau tsis ua haujlwm, thiab cov duab rov qab thiab kev ua haujlwm tau nruab rau ntawm lub server yog los ntawm tib tsev neeg. Yog tias qhov ua rau tsis ua haujlwm tseem tsis tau paub, koj yuav tsum tau saib xyuas kev nce qib ntawm kev thauj khoom ntawm lub operating system.

Ntsib cov Intel processors tshiab
02.04.2019/2017/14, Intel Corporation tshaj tawm qhov hloov tshiab tos ntev rau Intel® Xeon® Scalable Processors tsev neeg ntawm cov txheej txheem, tau qhia nyob rau nruab nrab xyoo XNUMX. Cov txheej txheem tshiab yog ua raws li microarchitecture codenamed Cascade Lake thiab tau tsim los ntawm kev txhim kho XNUMX-nm txheej txheem thev naus laus zis.
Los ntawm Naples mus rau Rome: tshiab AMD EPYC CPUs
Thaum Lub Yim Hli XNUMX, lub ntiaj teb pib ntawm kev muag khoom ntawm tiam thib ob ntawm AMD EPYC ™ kab tau tshaj tawm. Cov txheej txheem tshiab yog ua raws li microarchitecture Zen 2 thiab tau tsim los ntawm 7nm txheej txheem thev naus laus zis.
Es tsis txhob ib tug xaus
Peb cia siab tias koj nyiam peb cov ntawv, thiab xyoo tom ntej peb yuav sim los npog cov ncauj lus nthuav dav ntxiv thiab tham txog cov khoom tshiab tshaj plaws.
Peb ua kev zoo siab rau tag nrho peb cov neeg nyeem nyob rau lub Xyoo Tshiab yuav los tom ntej thiab thov kom lawv ua tiav lawv cov hom phiaj thiab kev loj hlob tsis tu ncua!
Hauv cov lus koj tuaj yeem ua kev zoo siab rau ib leeg, peb, thiab, tau kawg, sau yam koj xav nyeem txog xyoo tom ntej ntawm peb qhov blog :)
