Mayelana ne-noVNC consoles evikelekile, i-autoscaling e-Kubernetes, i-Haproxy e-Ostrovka kanye nomsebenzi wabaphathi nabahleli bohlelo

Sithumela amavidiyo aqoshiwe emibiko evela ku-Selectel MeetUp: ukuphathwa kwesistimu.

Ingemuva elincane

I-Selectel MeetUp ingumhlangano onezethulo ezimfushane nokuxhumana okubukhoma. Umqondo womcimbi ulula: lalela izikhulumi ezinhle, xhumana nozakwenu, shintshanisa ngolwazi, khuluma ngezinkinga zakho futhi uzwe ukuthi abanye bazixazulule kanjani. Ngokuvamile, yonke into ebizwa ngokuthi inethiwekhi emphakathini we-IT.

Sajabulela ukuhlangana okuncane mayelana ne-DevOps kanye nokutholakala okuphezulu kumasistimu wolwazi. Okokugcina, izikhulumi beziphuma ku-Selectel kuphela, kodwa ngokuhlangenwe nakho kwe-DevOps sabona ukuthi sidinga ukumema abafana abathakazelisayo abavela kwezinye izinkampani. Futhi wenze amagama acace kangcono kunenombolo ye-serial ye-meeting. Ngakho, kulo nyaka siwuqale kabusha umcimbi.

Ngo-September 12, kwaba nomhlangano wokuqala ngendlela entsha. Ndawonye nezikhulumi ezivela ku-VKontakte, UseDesk, Studyworld, sixoxe ngesimo namathemba okusebenza kwamakhasimende nge-IT yesiRashiya. Sanquma ukuthi singagcini lapho.

Ngomhla zi-3 ku-Okthoba, i-Selectel isingathe umhlangano wabalawuli besistimu. Kulokhu simeme izikhulumi ezivela ezinkampanini i-Cogia.de, i-Ostrovok ne-Digital Vision Labs. Sikhulume nge-Kubernetes, ikhodi yefa ezinhlelweni zesimanje kanye nomsebenzi wabaphathi neminye iminyango. Imagine - St. Petersburg, kusihlwa, lina, futhi sinegumbi lenkomfa eligcwele abaphathi besistimu. Awu, awukwazi kanjani ukukhuthazwa lapha? Vadim Isakanov wafika ukusebenza kwakhe kusukela Chelyabinsk.

Ngenkathi sisacabanga ngesihloko somhlangano olandelayo, sishicilela okurekhodiwe kwemibiko ngaphansi kokusikwa.

Isipiliyoni kuzixazululo zengqalasizinda emibikweni emi-4

i-noVNC iduduza amaseva azinikezele, u-Alexander Nikiforov, u-Selectel

Besibhekene nomsebenzi: ukunikeza amakhasimende ukufinyelela kude ekuphathweni kweseva. Lokhu kufinyelela kusekelwe kumojuli ye-BMC efakwe ebhodini lomama. Kodwa ukuyifinyelela ngokuqondile ngekheli le-IP lomphakathi kubeka engcupheni enkulu yezokuphepha, futhi ukuzama ukuyihlukanisa kwenza kube nzima ukwazi ngasohlangothini lweklayenti. U-Alexander Nikiforov ukhulume ngendlela yokuxazulula le nkinga e-Selectel, lapho saqala khona eminyakeni embalwa edlule nokuthi kwenzekani ngaphansi kwe-hood lapho sethula ikhonsoli ye-KVM kuphaneli yethu yokulawula.

I-Autoscaling in Kubernetes, Vadim Isakanov, Cogia.de

Elinye lamakhono abalulekile e-Kubernetes ukusetshenziswa kwezinsiza ezidingekayo kuphela, lapho amaqoqo nezinhlelo zokusebenza zizikala. Amathuluzi okulinganisa okuzenzakalelayo ku-Kubernetes anikezwa mahhala ngaphandle kwebhokisi. U-Vadim Isakanov wase-Cogia.de ukhulume ngezikhali zala mathuluzi nendlela yakhe yokusebenza no-Kubernetes.

“Phakamisa isandla sakho, osebenza noKubernetes. Manje phakamisa isandla sakho uma umazi kahle uKubernetes.”

Ngokwesibonelo, Vadim wabhala ngomhlangano ekhasini lakho le-Facebook. Kunombiko, amaslayidi avela embikweni wakhe kanye nemibono ehlukahlukene. Vadim, ngiyabonga!

Indaba yokuzulazula kumadokhumenti e-Haproxy, u-Denis Bozhok, "Islet"

Ithimba le-Ostrovok.ru lihlinzeka ngamasevisi amancane angu-130. Uma othile esesha ihhotela e-St. Petersburg, isicelo siya enkonzweni yokuhlanganiswa kwemiphumela, bese kuba yi-microservice yakwa-Suppliard, esabalalisa izicelo kubahlinzeki bamahhotela bangaphandle. Lokhu kumayelana nokuxhumana okungu-450 XNUMX ngesikhathi esisodwa. Ukuze usebenze nabahlinzeki bangaphandle, inkampani yaqala ukusebenzisa i-Nginx, futhi manje isebenzisa i-Haproxy. UDenis Bozhok ukhulume ngama-nuances avela phakathi nomsebenzi onjalo.

"Ngemva kwesikole, ngafunda ukupheka, ngabe sengithatha izindlela zokupheka ezingalungile, ngamafuphi, konke kufiphele, futhi manje ngibhekene nengqalasizinda yenkampani yase-Ostrovok."

Indlela yokwenza ubungane phakathi kwamaqembu ahlukene emavikini angu-6, uDmitry Popov, Digital Vision Labs

Ngesinye isikhathi, ithimba le-Digital Vision Labs labhekana nenkinga yokukhula: ibhizinisi lase lilungele ukubamba iqhaza kumaphrojekthi amasha, kodwa ingqalasizinda ye-IT ayikwazanga ukuhambisana nayo. Umnyango wokuphatha uhlelo wawuhlale usesimweni esiphuthumayo, imisebenzi eqoqiwe eyayingenaso isikhathi sokuxazululwa. Ukusebenza kahle kwakwehla. UDmitry Popov ukhulume ngezizathu ezingabonakali zesimo samanje nokuthi bakwazi kanjani ukusungula ukuphathwa kwephrojekthi.

“Okwamanje lapho sibona ukuthi kukhona okumele kushintshwe, cishe u-70% wezicelo zabaphathi bohlelo aziqedwanga ngesikhathi. Amanye ama-25% ezicelo alahlekile ohlelweni. Futhi u-100% wezicelo weza ngaphandle kokucaciswa. Kuze kube manje, u-27% wezicelo awukaqedwa ngesikhathi (sisenendawo yokukhula), u-0% wezicelo ulahlekile ohlelweni futhi u-9% wezicelo ufika ngaphandle kwemininingwane yobuchwepheshe.”

Ukukhethwa kwesihloko esilandelayo kungokwakho

Njengoba besho, uma uqala ukwakha umphakathi we-IT, akunakwenzeka ukuyeka. Isizini yethu yokuqala yemihlangano iyisivivinyo, sizobe senza izihloko nezindlela ezahlukene. Yize isihloko somhlangano olandelayo singakanqunywa, kungaba kuhle uma uphakamisa izihloko zemihlangano emazwaneni bese ubhala ukuthi ubani ofuna ukumbona njengesikhulumi. Futhi sizohlela umhlangano olandelayo, sicabangela impendulo.

Phakathi kwemicimbi ezayo, ngo-Okthoba 24 sizophatha ingqungquthela yaminyaka yonke ye-Selectel Networking Academy. Abamele Amanethiwekhi Ama-Extreme, iJuniper, iHuawei, i-Arista Networks kanye ne-Selectel bazonikeza izethulo ngemikhiqizo yenethiwekhi kanye namacala ohlelo lwabo lokusebenza.

Nazi izizathu ezi-3 zokuthi kungani inkomfa ingase ibe nentshisekelo kuwe:

• izikhulumi zizokhuluma ngezinyathelo zokuqinisekisa ukusebenza okuzinzile kwengqalasizinda yenkampani, zixoxe ngamacala okusetshenziswa kobuchwepheshe;
• uzokwabelana ngolwazi lwakho nozakwenu, ufunde mathupha mayelana nezitayela ekuthuthukisweni kobuchwepheshe benethiwekhi;
• buza ochwepheshe noma yini oyifunayo mayelana nesakhiwo senethiwekhi.

Engqungqutheleni uzokwazi futhi ukuxoxa noKirill Malevanov, umqondisi wethu wezobuchwepheshe. U-Kirill ubhala izindatshana mayelana nobuchwepheshe benethiwekhi, uya ezingqungqutheleni zamazwe ngamazwe futhi unolwazi oluningi kulo mkhakha. Uma ungakayifundi, nasi esinye sezindatshana zakhe zakamuva ezimayelana noHabré mayelana nokuhlanganisa amaphrojekthi ezikhungweni zedatha ezahlukene.

Njengenjwayelo, uhlelo lokubhalisa kanye nomcimbi lungatholakala kusixhumanisi - slc.tl/TaxIp
