Kuchokera pazomwe tafotokozazi, zitha kuwoneka kuti kugwidwa kwa magalimoto mumtambo kuyenera kuyang'ana kwambiri pakugwira magalimoto akum'mawa ndi kumadzulo pakati pa makina enieni ndi zovuta zogwirira ntchito. Nthawi yomweyo, potengera mawonekedwe amtambo wamtambo, kusonkhanitsa magalimoto mumtambo kumayenera kudutsa njira yomwe ilipo yagalasi yosinthira yachikhalidwe, ndikuzindikira kusonkhanitsa kosinthika komanso kodziwikiratu ndikuwunikira kutumizidwa, kuti zigwirizane ndi ntchito zodziwikiratu ndikukonza cholinga cha netiweki yamtambo. Kusonkhanitsa magalimoto mumtambo kuyenera kukwaniritsa zolinga izi:
1) Zindikirani ntchito yojambulira magalimoto akum'mawa ndi kumadzulo pakati pa makina enieni
2) Kujambula kumatumizidwa kumalo ogwiritsira ntchito makompyuta, ndipo zomangamanga zomwe zimagawidwa zimagwiritsidwa ntchito pofuna kupewa zovuta ndi zovuta zomwe zimachitika chifukwa cha kusintha kwa galasi.
3) Imatha kuzindikira kusintha kwazinthu zamakina mumtambo, ndipo njira yosonkhanitsira imatha kusinthidwa zokha ndikusintha kwazinthu zamakina.
4) Chida chojambulira chiyenera kukhala ndi njira yotetezera mochulukira kuti muchepetse kukhudzidwa kwa seva
5) Chida chojambula chokha chimakhala ndi ntchito yokonza magalimoto
6) Pulatifomu yojambula imatha kuyang'anira kuchuluka kwa magalimoto omwe asonkhanitsidwa pamakina
Kusankhidwa kwa Virtual Machine Traffic Capturing Mode mu Cloud Environment
Kujambula kwa magalimoto pamakina mumtambo kumayenera kutumiza kafukufukuyu ku node yamakompyuta. Malinga ndi malo osonkhanitsira omwe atha kuyikidwa pa node yamakompyuta, makina ojambulira magalimoto mumtambo amatha kugawidwa m'njira zitatu:Agent Mode, Virtual Machine ModendiHost Mode.
Virtual Machine Mode: makina ojambulira ogwirizana amayikidwa pamtundu uliwonse wamtundu wamtambo, ndipo kujambula kofewa kumayikidwa pamakina ojambulira. Magalimoto a wolandirayo amawonetsedwa pamakina ojambulira poyang'ana kuchuluka kwa maukonde pamakina osinthira, ndiyeno makina ojambulira amaperekedwa ku nsanja yojambulira magalimoto odzipatulira kudzera pamakhadi odzipereka. Kenako imagawidwa ku nsanja iliyonse yowunikira ndi kusanthula. Ubwino wake ndikuti softswitch bypass mirroring, yomwe ilibe kulowerera pamakhadi apaintaneti omwe alipo komanso makina pafupifupi, amathanso kuzindikira malingaliro akusintha kwa makina ndi kusamuka kwazinthu zodziwikiratu pogwiritsa ntchito njira zina. Zoyipa zake ndikuti ndizosatheka kukwaniritsa chitetezo chochulukirachulukira pogwira makina ongolandira mosadukiza, ndipo kukula kwa magalimoto omwe atha kuwonetsedwa kumatsimikiziridwa ndi magwiridwe antchito a switch, omwe amakhudza kukhazikika kwa switch. M'malo a KVM, nsanja yamtambo imayenera kutulutsa mofananamo tebulo lakuyenda kwazithunzi, zomwe zimakhala zovuta kuyang'anira ndikusamalira. Makamaka pamene makina ogwiritsira ntchito akulephera, makina ogwiritsira ntchito amafanana ndi makina a bizinesi ndipo adzasamukira ku makamu osiyanasiyana ndi makina ena enieni.
Agent Mode: Ikani chojambula chofewa chojambula (Agent Agent) pamakina aliwonse omwe amafunikira kujambula kuchuluka kwa anthu mumtambo, ndikuchotsa kum'mawa ndi kumadzulo kwa chilengedwe chamtambo kudzera pa pulogalamu ya Agent, ndikugawa ku nsanja iliyonse yowunikira. Ubwino wake ndikuti ndizodziyimira pawokha papulatifomu, sizimakhudza magwiridwe antchito akusinthana, zimatha kusamuka ndi makina owonera, ndipo zimatha kusefa magalimoto. Zoyipa zake ndikuti othandizira ambiri amafunikira kuyang'aniridwa, ndipo chikoka cha Wothandizirayo sichingayikidwe pamene cholakwika chichitika. Khadi la netiweki lomwe lilipo liyenera kugawidwa kuti liwononge magalimoto, zomwe zingakhudze kuyanjana kwa bizinesi.
Host Mode: potumiza kafukufuku wodziyimira pawokha pagulu lililonse la anthu omwe ali mumtambo, imagwira ntchito motsata wolandirayo, ndikutumiza kuchuluka kwa anthu omwe agwidwa ku nsanja yojambulira anthu. Ubwino ndi wathunthu kulambalala limagwirira, palibe kulowerera kwa makina pafupifupi, khadi malonda maukonde ndi pafupifupi makina lophimba, yosavuta wolanda njira, kasamalidwe yabwino, palibe chifukwa kukhala paokha makina pafupifupi, opepuka ndi zofewa kafukufuku kupeza akhoza kukwaniritsa chitetezo mochulukira. Monga njira yochitira alendo, imatha kuyang'anira makina omwe ali ndi makinawo komanso momwe makinawo amagwirira ntchito kuti atsogolere kutumizidwa kwa njira yagalasi. Zoyipa zake ndizakuti zimafunika kugwiritsa ntchito kuchuluka kwa zinthu zomwe zimagwira ntchito, ndipo zotsatira zake ziyenera kutsatiridwa. Kuphatikiza apo, nsanja zina zowoneka bwino sizingagwirizane ndi kutumizidwa kwa ma probes apulogalamu pa wolandila.
Kuchokera pazomwe zikuchitika pamsika, makina owoneka bwino ali ndi ntchito mumtambo wapagulu, ndipo Njira ya Agent ndi Host Mode ili ndi ogwiritsa ntchito mumtambo wachinsinsi.
