Amaholide amade aseduze, okusho ukuthi kuzoba nesikhathi sokubuyela kumabhukhimakhi akho okuthi Funda kamuva noma ufunde kabusha izindatshana ezibalulekile zonyaka ophumayo. Kulokhu okuthunyelwe, sikuqoqele futhi sikulungiselele uhlu lwezinto ezithakazelisa kakhulu ezivela kubhulogi yethu ngo-2019 futhi sithemba ukuthi zizoba usizo kuwe.
Unyaka odlule ubuthakazelisa futhi unemicimbi eminingi: ubuchwepheshe obusha, isivinini esisha nezinselele ezintsha zobungcweti. Ukusiza abafundi bethu ukuthi bahambisane nenqubekelaphambili, sizamile ukubika ngayo yonke imicimbi ebalulekile yemboni kubhulogi yethu ngokushesha okukhulu. Onjiniyela bethu nabahloli basisize kakhulu kulokhu, bezama ihadiwe emisha nemikhiqizo yesofthiwe kokuhlangenwe nakho kwabo siqu. Lonke ulwazi oluqoqiwe lwagcina luhlelekile futhi lwaba izindatshana zonjiniyela, onjiniyela, abaphathi bezinhlelo kanye nabanye ochwepheshe bezobuchwepheshe. Siyajabula ukwabelana nawe ngolwazi lwethu, futhi sithemba ukuthi okungenani ngezinye izikhathi sikwazile ukukusiza wenze ukukhetha okufanele futhi wonge isikhathi sakho. Siyabonga ngokuba nathi!
Okonjiniyela
Ayinaseva kuma-racks
I-Serverless ayiphathelene nokungabi khona ngokomzimba kwamaseva. Lokhu akuwona umbulali wezitsha noma umkhuba odlulayo. Lena indlela entsha yokwakha amasistimu emafini. Esihlokweni sanamuhla sizothinta ukwakhiwa kwezinhlelo zokusebenza ezingenayo i-Serverless, ake sibone ukuthi umhlinzeki wesevisi ye-Serverless kanye namaphrojekthi womthombo ovulekile adlala yiphi indima. Ekugcineni, ake sikhulume ngezinkinga zokusebenzisa i-Serverless.
Ukusebenzisa isixhumi esibonakalayo somsebenzisi se-OpenStack LBaaS
Kusuka kumbhali: “Ngihlangabezane nezinselelo ezibalulekile lapho ngisebenzisa isixhumi esibonakalayo somsebenzisi esilinganisa umthwalo kumafu ayimfihlo abonakalayo. Lokhu kungenze ngacabanga ngendima ye-frontend, engifuna ukwabelana ngayo kuqala. "
Okwabaphathi besistimu
Kusukela ku-High Ceph Latency kuya ku-Kernel Patch usebenzisa i-eBPF/BCC
I-Linux inenani elikhulu lamathuluzi okulungisa iphutha le-kernel nezinhlelo zokusebenza. Iningi lazo linomthelela omubi ekusebenzeni kohlelo lokusebenza futhi azikwazi ukusetshenziswa ekukhiqizeni.
Eminyakeni embalwa edlule, elinye ithuluzi lasungulwa - i-eBPF. Kwenza kube nokwenzeka ukulandelela i-kernel nezinhlelo zokusebenza zomsebenzisi nge-overhead ephansi futhi ngaphandle kwesidingo sokwakha kabusha izinhlelo nokulayisha amamojula ezinkampani zangaphandle ku-kernel.
IP-KVM nge-QEMU
Ukuxazulula izinkinga zokuqalisa uhlelo lokusebenza kumaseva ngaphandle kwe-KVM akuwona umsebenzi olula. Sizidalela i-KVM-over-IP ngesithombe sokubuyisela kanye nomshini obonakalayo.
Uma kuphakama izinkinga ngohlelo lokusebenza kuseva ekude, umlawuli ulanda isithombe sokutakula futhi enze umsebenzi odingekayo. Le ndlela isebenza kahle uma imbangela yokwehluleka yaziwa, futhi isithombe sokubuyisela kanye nesistimu yokusebenza efakwe kuseva ivela emndenini ofanayo. Uma imbangela yokwehluleka ingakaziwa, udinga ukuqapha inqubekelaphambili yokulayisha uhlelo lokusebenza.

Hlangana namaphrosesa amasha e-Intel
02.04.2019/2017/14, i-Intel Corporation yamemezela isibuyekezo osekunesikhathi silindelwe emndenini wamaphrosesa we-Intel® Xeon® Scalable processors, owethulwe maphakathi no-XNUMX. Amaphrosesa amasha asekelwe esakhiweni esincane esinekhodi yeCascade Lake futhi akhelwe phezu kobuchwepheshe benqubo ye-XNUMX-nm obuthuthukisiwe.
Ukusuka eNaples kuya eRoma: ama-CPU amasha e-AMD EPYC
Ngo-Agasti XNUMX, ukuqaliswa kokuthengiswa komhlaba wonke kwesizukulwane sesibili somugqa we-AMD EPYC™ kwamenyezelwa. Amaphrosesa amasha asekelwe ku-microarchitecture I-Zen 2 futhi zakhelwe phezu kobuchwepheshe benqubo ye-7nm.
Esikhundleni isiphetho
Sithemba ukuthi uzithandile izihloko zethu, futhi ngonyaka ozayo sizozama ukumboza izihloko ezithakazelisayo nakakhulu futhi sikhulume ngemikhiqizo emisha ebanda kunazo zonke.
Sihalalisela bonke abafundi bethu ngoNyaka Omusha ozayo futhi sibafisela impumelelo yezinhloso zabo nokukhula okuqhubekayo kochwepheshe!
Kumazwana ungahalalisela omunye nomunye, thina, futhi, yiqiniso, bhala lokho ongathanda ukufunda ngakho ngonyaka ozayo kubhulogi yethu :)
