Server Virtualization: A Definition

Chii Chaicho Chaizvo Chevhavha Inoshandiswa, uye Nei Unofanira Kuishandisa?

Kana iwe uri mutungamiri wehurongwa umo vashandisi vanoda kuve vakasiyana kubva kune mumwe uye kubva kune yepakutanga sevha, nzira yakaderera uye inobudirira yekuita izvi ndeyokugadzira sevhisi yega yega kuburikidza nekugadzirisa kunonzi "server virtualization."

Shandisi yekushandiswa kwemashoko ndiyo pfungwa yekutora sepaini yepanyama uye, nekubatsira kwekugadzira purogiramu software, kuparadzanisa sevha, kana kuigadzirisa, kuitira kuti inoratidze se "sevhisi sevhariji" dzakawanda, rimwe nerimwe rayo rinogona kutora kopi yavo yebasa rekushandisa .

Nenzira iyi, panzvimbo peyo yese sevha yakatsaurirwa kune chimwe chinhu, inogona kushandiswa nenzira dzakasiyana siyana.

Makomborero eSeva Virtualization

1. Inoponesa mari paIt cost. Paunoparadzanisa sevha imwe yemutauro mumichina yakasiyana-siyana, iwe unogona kushandisa, kushanda nekugadzirisa maitiro akawanda ekushandura maitiro panguva imwechete pane iyo imwe chete yemuviri webasa. Vashoma masipirini epanyama anoreva mari shoma inoshandiswa pane mavhareji iwayo.

2. Inoderedza nhamba yemasevhisi chaiwo kambani inofanira kunge ine nzvimbo yayo. Pasinei noukuru hwekambani, nguva dzose iri pfungwa yakanaka kuchengetedza nzvimbo.

3. Inoderedza pasi kushandiswa kwesimba sezvo pane vashoma masipirini epanyama anodya simba. Izvozvo zvinonyanya kukosha, zvichipiwa kuenderera kune hutachiona hweU IT nekugadzirisa.

4. Inoita nzvimbo dzakasununguka dzemushandisi. Kuchengeta zvinhu zvose zvakakosha kunonyanya kukosha kune zvinangwa zvakadai sekuongorora software (saka mapurogiramu anogona kukwanisa kushandiswa mune imwe seva ye virusi pasina kuchinja vamwe).

1. Zvigadziriswe zvekutengesa webhupu. Apo mapeji akawanda evanhu anogona kukwanisa pamakombiyuta mamwechete, kupiwa kwemaseva kunowedzerwa zvisingabhadhari mari yakawedzerwa.

Aina dze Server Virtualization

Iko kune marudzi matatu akasiyana e-server virtualization:

1. Virtual machine model (kana kuti "kugadzirisa zvakakwana"): Kubva pane muenzi / muparidzi paradigm, shandisa rudzi runokosha rwemapurisa anonzi hypervisor. Vatungamiri vanogona kugadzira vaenzi nehutano hwakasiyana-siyana.

1. Paravirtual machine (PVM): yakafanana nehuwandu hwemagetsi, zvakare hunobva kune mukuru / muenzi paradigm. Inogonawo kuendesa maSeses akawanda.

2. OS-level: kwete kubva paanopinda / muparadhiso. Vashanyi vanofanira kushandisa imwecheteyo seyo mutungamiri / mutariri, uye zvikamu zvakaparadzana zvachose kubva kune mumwe (naizvozvo zvinetso mune imwe hazvigone kuchinja chero vamwe).

Mabasa mu Virtualization

Zvimwe zvevhesi-nzvimbo dzakabatana-zvingaita iwe unogona kuwana pawebsite dzebasa zvinogona kusanganisira:

• virtualization engineer

• virtual architect

• server virtualization systems administrator

• cloud virtualization engineer

Major Players mu Server Virtualization Arena:

• VMWare

• Microsoft

• Citrix;

• Red Hat.

Remangwana reSeva Virtualization

Inzwisise kuti maitiro chaiyo haasi pfungwa yeruzivo. (Makombiyuta masayendisiti ave achigadzira "vakukuru" kwemakumi emakore.) Zvisinei, kushandiswa kwemaseva kwaive kwakagadzirwa mumakore ekupedzisira makumi mapfumbamwe.

Zvakatora nguva kuti zvigadzire, asi mumakore akapfuura, kunyanya kwekushanda kwebasa kwakashandurwa. Makambani akaziva kuti akanga ari kuparadza zvigadzirwa, uye teknolojia yepamusoro yakagamuchirwa nevakawanda senzira yekubatanidza mabhizinesi avo 'zvekushanda kwekambani. Mazuva ano, shanduro yekuita sevhisi yakawanda yezvinodiwa zvinokosha kudarika pfungwa yakakosha.

Nokudaro mupfungwa, kunyanya kushandiswa kwevhavha sekushambadzira sekushambadzira basa hakugone kukuisa mukutarisira kwakanyanya pazviri (kunyange zvichiri kuenderera mberi). Zvisinei, kuzivikanwa nekushanda kwekugadzirisa zvinhu kunokwanisa kukuisa iwe kune zvese zviri kuuya mberi. Maererano neDataCenterKnowledge, iyo inogona kutaridzika sebasa nekuiswa kwekushanda, kushandiswa kwemagetsi, kushandiswa kwemashandisi, nezvimwewo.
