Kusankha Njira Yojambulira Magalimoto Pakompyuta Pakompyuta mu Malo Amtambo
Kujambula magalimoto a makina enieni mumlengalenga wamtambo kuyenera kuyika chofufuzira chosonkhanitsa ku node ya kompyuta. Malinga ndi malo omwe malo osonkhanitsira omwe angagwiritsidwe ntchito pa node ya kompyuta, mawonekedwe ojambulira magalimoto a makina enieni mumlengalenga wamtambo akhoza kugawidwa m'njira zitatu:Njira Yothandizira, Makina Ogwiritsira Ntchito PakompyutandiNjira Yolandirira.
Makina Ogwiritsira Ntchito Pakompyuta: makina ojambulira ogwirizana amayikidwa pa chipangizo chilichonse chamagetsi, ndipo chojambulira chofewa chimayikidwa pa chipangizo chojambulira. Magalimoto a chipangizocho amawonetsedwa ku chipangizo chojambulira powonetsa kuchuluka kwa magalimoto a khadi la intaneti pa chosinthira chamagetsi, kenako makina ojambulira amatumizidwa ku chipangizo chachikhalidwe chojambulira magalimoto kudzera pa khadi la intaneti lodzipereka. Kenako amagawidwa ku chipangizo chilichonse chowunikira ndi kusanthula. Ubwino wake ndi wakuti softswitch bypass mirroring, yomwe ilibe kulowerera pa khadi la bizinesi lomwe lilipo komanso makina amagetsi, imatha kuzindikiranso kusintha kwa makina amagetsi ndi kusamuka kwa mfundo kudzera m'njira zina. Choyipa chake ndichakuti sizingatheke kupeza njira yotetezera overload pojambula makina amagetsi omwe amalandira magalimoto mosasamala, ndipo kukula kwa magalimoto omwe angawonetsedwe kumatsimikiziridwa ndi momwe switch yeniyeni imagwirira ntchito, yomwe imakhudza kukhazikika kwa switch yeniyeni. Mu KVM, nsanja yamtambo iyenera kutulutsa tebulo loyendera zithunzi mofanana, lomwe ndi lovuta kulisamalira ndikusamalira. Makamaka makina ojambulira akalephera, makina ojambulira amakhala ofanana ndi makina amagetsi amalonda ndipo amasamutsiranso ku ma host osiyanasiyana ndi makina ena amagetsi.
Njira Yothandizira: Ikani chida chojambulira chofewa (Agent Agent) pa makina aliwonse ofunikira kujambula kuchuluka kwa magalimoto mumtambo, ndikutulutsa kuchuluka kwa magalimoto kum'mawa ndi kumadzulo kwa mtambo kudzera mu pulogalamu ya Agent agent, ndikugawa ku nsanja iliyonse yowunikira. Ubwino wake ndi wakuti sichidalira nsanja yowunikira, sichikhudza magwiridwe antchito a switch yeniyeni, chimatha kusuntha ndi makina owonera, ndipo chimatha kusefa kuchuluka kwa magalimoto. Zoyipa zake ndichakuti othandizira ambiri amafunika kuyang'aniridwa, ndipo mphamvu ya Agent yokha singachotsedwe pamene cholakwika chikuchitika. Khadi la netiweki yopangira yomwe ilipo iyenera kugawidwa kuti iwonetse kuchuluka kwa magalimoto, zomwe zingakhudze kuyanjana kwa bizinesi.
Njira Yolandirira: poika pulogalamu yodziyimira payokha yosonkhanitsira deta pa chipangizo chilichonse chamagetsi chomwe chili mumtambo, imagwira ntchito munjira yogwirira ntchito pa chipangizocho, ndipo imatumiza anthu omwe agwidwa kupita ku nsanja yodziwika bwino yojambulira deta. Ubwino wake ndi njira yodutsa, palibe kulowerera kwa makina enieni, khadi la netiweki ya bizinesi ndi switch ya makina enieni, njira yosavuta yojambulira deta, kasamalidwe kosavuta, palibe chifukwa chosungira makina enieni odziyimira payokha, kupeza ma probe opepuka komanso ofewa kumatha kuteteza kwambiri. Monga njira yojambulira deta, imatha kuyang'anira zinthu za makina enieni ndi magwiridwe antchito kuti itsogolere kuyika kwa njira yowonera. Zoyipa zake ndi zakuti imafunika kugwiritsa ntchito zinthu zina za chipangizocho, ndipo zotsatira zake ziyenera kuganiziridwa. Kuphatikiza apo, nsanja zina za pa intaneti sizingathandize kuyika ma probe a mapulogalamu pa chipangizocho.
Kuchokera momwe zinthu zilili panopa mumakampani, mawonekedwe a makina ogwiritsira ntchito pa intaneti ali ndi mapulogalamu mu cloud ya anthu onse, ndipo mawonekedwe a Agent ndi Host Mode ali ndi ogwiritsa ntchito ena mu cloud yachinsinsi.
