Victor Kondoba ΠΈ Svetlana Zavyalova vachagovera ruzivo rwavo rwekushandisa magadzirirwo ekuzivikanwa kwekutaura kwemunharaunda paunenge uchigadzira tsigiro, ratidza zvaunofanira kutarisa pazviri uye zvaunogona kupa kuti uwedzere kushanda zvakanaka.
Ndezvipi zvimwe zvichange zvichitaurwa nezvazvo?
Munguva pfupi yapfuura, rudzi rutsva rwe data rwakaonekwa muRedis 5 - nzizi, uku ndiko kuita kwemazano kubva kune yakakurumbira meseji broker Kafka. Denis Kataev (Tinkoff.ru) ichatsanangura kuti nei hova dzichidikanwa, kuti dzinosiyana sei nemitsara yenguva dzose, ndeupi mutsauko pakati peKafka neRedis hova, uye zvakare ichakuudza nezve misungo yakakumirira iwe.

Mushure mehurukuro, iwe uchave nekunzwisisa zviri nani kuti .NET Core inoshanda sei pasi pehodhi.
Uye musoro wakavhoterwa zvakanyanya pane saiti.
Chimurenga chakanyarara chakaitika muna 2014, uye maungira ayo ari kutibata. Kubva panguva ino zvichienda mberi, zvivakwa zvinova zvisingaonekwe zvachose uye zvinorega kuita basa. Izvi hazvisi zvemashini chaiwo kana midziyo - yatove chinhu chekare, asi nezve imwe budiriro yemazano emafu masevhisi - AWS Lambda (isu tinobhadhara chete processor nguva). Achishandisa muenzaniso weake backend purojekiti, mugadziri mu Vakaipa Martians Nikolay Sverchkov ichakuudza zvese nezve chikamu chinoshanda chekushanda ne serverless: zvakaoma sei kutanga, ingani zvinyorwa uye zvidzidzo zviripo, pane tsigiro yezviyero zvinogamuchirwa, maitiro ekuyedza munharaunda, zvinodhura zvakadii, mutauro upi. zviri nani kushandisa, ndeipi basa stack inonyanya kukosha.
Master class
CTO mune Mastery.pro Andrey Fefelov achaitisa master class umo iye nevatori vechikamu vachavaka nyore kukanganisa-kushivirira cluster ye 3 nodes pa postgres, patroni, consul, s3, walg, ansible.
Mushure mekirasi yatenzi, iwe unozokwanisa kuvhura sumbu rakadaro kubva kutanga uchishandisa akapihwa Ansible playbooks.
Mishumo yese kubva kumusangano wegore rapfuura inogona kutariswa pa
Zvinyorwa zvemishumo yese uye kunyoresa - pa .
