Yuav ua li cas ua phooj ywg ntawm cov pab pawg sib txawv hauv 6 lub lis piam, Dmitry Popov, Digital Vision Labs
Qee lub sij hawm, pab pawg Digital Vision Labs ntsib teeb meem kev loj hlob: kev lag luam tau npaj los koom nrog cov haujlwm tshiab, tab sis IT infrastructure tsis tuaj yeem ua raws li nws. Lub chaw saib xyuas kev tswj hwm tau tas li nyob rau hauv hom xwm txheej ceev, cov haujlwm tau sau tseg uas tsis muaj sijhawm los daws. Kev ua tau zoo tau poob.

Nov yog 3 lub laj thawj vim li cas lub rooj sab laj yuav txaus siab rau koj:
- cov neeg hais lus yuav tham txog kev ntsuas kom ruaj ntseg ntawm lub tuam txhab kev tsim kho vaj tse, sib tham txog cov teeb meem ntawm kev siv thev naus laus zis;
- koj yuav qhia koj cov kev paub dhau los nrog cov npoj yaig, kawm thawj zaug txog cov ncauj lus hauv kev txhim kho network thev naus laus zis;
- nug cov kws tshaj lij txhua yam koj xav tau txog network architecture.
Ntawm lub rooj sab laj koj tseem tuaj yeem tham nrog Kirill Malevanov, peb tus thawj coj ua haujlwm. Kirill sau cov lus hais txog network technologies, mus koom lub rooj sib tham thoob ntiaj teb thiab muaj kev paub dhau los hauv thaj chaw.
