Virtualization Server: Tanthauzo

Kodi Chimodzimodzinso ndi Seva Chothandizira, ndi Chifukwa Chiyani Muyenera Kuigwiritsa Ntchito?

Ngati ndinu woyang'anira dongosolo limene ogwiritsa ntchito akuyenera kukhala osiyana ndi wina ndi mzake, njira yotsika mtengo komanso yowonjezera yochitira izi ndikupanga ma seva apadera kupyolera mu ndondomeko yotchedwa "seva virtualization."

Pulogalamu yamtumiki ndilo lingaliro la kutenga seva ya thupi ndipo, mothandizidwa ndi mapulogalamu apamwamba, kulekanitsa seva, kapena kugawaniza, kuti iwoneke ngati "maseva ambiri," iliyonse yomwe ingayendetse ntchito yawo yowonetsera .

Mwanjira iyi, m'malo mwa seva yonse yopatulidwa ku chinthu chimodzi, ikhoza kugwiritsidwa ntchito m'njira zosiyanasiyana.

Ubwino wa Server Virtualization

1. Sungitsa ndalama pa ndalama za IT. Pamene mutagawira seva imodzi mu makina angapo, mukhoza kugwiritsa ntchito, kuyendetsa ndi kuyendetsa maulendo angapo ogwiritsira ntchito nthawi yomweyo pa seva imodzi yokha. Seva zochepa zochepa zimagwiritsa ntchito ndalama zochepa pa maseva awo.

2. Amachepetsa chiwerengero cha maselo enieni omwe kampani iyenera kukhala nayo pamalo ake. Mosasamala kukula kwa kampani, ndibwino nthawi zonse kusunga malo.

3. Amachepetsa kugwiritsira ntchito mphamvu zamagetsi chifukwa pali ma servers ochepa omwe amadya mphamvu. Izi ndizofunikira kwambiri, chifukwa cha zovuta zowonongeka za IT kupanga ndi kukhazikitsa.

4. Amapanga malo osungira okhaokha. Kusunga chilichonse chosiyana ndizothandiza makamaka monga kuyesa mapulogalamu (kotero olemba akhoza kuyendetsa ntchito mu seva imodzi yokha popanda kukhudza ena).

1. Perekani makasitomala ogwiritsira ntchito okwera mtengo. Pamene ma seva ambiri angagwirizane ndi makompyuta omwewo, kupezeka kwa maseva kumawonjezeka chifukwa palibe ndalama zina zowonjezera.

Mitundu ya Virtualization Server

Pali mitundu itatu yosiyana ya seva yabwino:

1. Mtengo wa makina abwino (kapena "mphamvu yokwanira"): Mogwirizana ndi wolandiridwa / guest guest paradigm, gwiritsani ntchito mapulogalamu apadera otchedwa hypervisor. Olamulira angapange alendo ndi machitidwe osiyana.

1. Makina a Paravirtual (PVM): ofanana ndi chikhalidwe chokwanira, komanso chokhazikitsidwa ndi gulu la alendo / alendo. Mungathenso kuyendetsa ma OSes ambiri.

2. OS-level: osachokera kwa alendo / alendo paradigm. Otsatira ayenera kugwiritsa ntchito OS omweyo monga woyang'anira / wothandizira, ndipo magawo amasiyana kwambiri ndi wina ndi mzake (kotero mavuto m'modzi sangathe kukhudza ena).

Ntchito mu Virtualization

Zina mwa maudindo omwe ali nawo pakompyuta omwe mungawapeze pa webusaiti ya ntchito angaphatikizepo:

• katswiri wodziwa bwino ntchito

• wokonza zomangamanga

• seva virtualization mawonekedwe woyang'anira

• mtambo wa virtualization engineer

Omasewera Wamkulu mu Server Virtualization Arena:

• VMWare

• Microsoft

• Citrix;

• Red Hat.

Tsogolo la Sutumiki Yowonjezera

Kumvetsetsa kuti virtualization yokha si mfundo yatsopano. (Asayansi a sayansi akhala akupanga "opambana" kwa zaka makumi ambiri.) Komabe, mphamvu ya maseva idapangidwira kumapeto kwa zaka za m'ma 90.

Zinatenga kanthawi kuti tigwire, koma zaka zapitazi, kukula kwa seva virtualization yakhala ikuphulika. Makampani anazindikira kuti akuwononga chuma, ndipo zipangizo zamakono zamagetsi zinasankhidwa ndi ambiri monga njira yogwirizira bizinesi yawo. Masiku ano, kupatsa ma seva ndizofunikira kwambiri kuposa chikhalidwe chapamwamba.

Poganizira zimenezi, kugwiritsidwa ntchito pa seva yokhazikika monga ntchito yosuntha sikungakulepheretseni nokha (ngakhale kuti mukupitiriza kusintha). Komabe, kukhala wodziwa bwino kugwiritsa ntchito mphamvu zomangamanga kungakupangitseni zonse zomwe zikubwera kutsatira. Malingana ndi DataCenterKnowledge, izo zikhoza kuwoneka ngati ntchito ndi kubweretsa mapulogalamu, makina ogwirira ntchito, makina othandizira, ndi zina.
