Isticmaale ahaan, qaarkiin ayaa laga yaabaa in ay ku qanci waayaan labada eray ee hadda ka muuqda ku dhawaad ​​goob kasta oo farsamo:  Cloud Computing iyo Virtualization . Waxaan ku daboolnay maqaallo horudhac ah oo ku saabsan Cloud Computing laakiin Virtualization halkan laguma daboolin. Haddaba aan isku dayno inaan fahanno waxa ay tahay Virtualization iyo waxa ay bixiso taas oo ay ugu wacan tahay in ay noqotay kelmad guux ah.

Waa maxay Virtualization ee kombiyuutarada

Marka hore^(First) , faham in Virtualization - ku aanu ahayn wax cusub - had iyo jeer way jirtay, waxay lahayd muhiimad weyn inta lagu jiro wakhtiga Kombuyuutarka Mainframe^{(Mainframe Computer)} halkaas oo looga baahnaa in loo wadaago agabka si wax ku ool ah, maadaama ay qaali ahaayeen wakhtigaas.

Markii uu yimid wakhtiga Virtualization -ka ayaa lumiyay muhiimaddii ay lahayd laba sababood oo waaweyn dartood:

1. Kharashaadka agabka^(Hardware) ayaa si aad ah hoos ugu dhacay LSI iyo VLSI .
2. Nashqada x86 ayaa noqotay mid caan ah.

Marka la soo koobo:

Virtualization waa qaab kasta ama hab kasta ama lakab kaas oo u qaybiya agabka sida server-yada, xog-ururinta, shabakadaha, nidaamka hawlgalka mid ama in ka badan oo deegaan fulineed oo kala duwan.

Waxay u ogolaataa isticmaalayaasha inay ku socodsiiyaan hal agab jireed sida serverkaaga ama aaladda kaydinta si ay ugu muuqato inay u socoto ilo badan oo macquul ah. Waxa dhabta ah ee ay dhab ahaantii qabato waa in ay soo saarto sifooyinka ilaha xisaabinta si hababka kale, codsiyada, ama nidaamyada ay ula falgalaan agabyadaas qaab aan is khilaafayn.

Tusaalooyinka waxa ay noqon karaan qaybinta wadista, iyada oo la isticmaalayo emulator-ka mobaylka, ama isticmaalka alaabada sida Virtual PC ama VMware alaabta miistarka.

Virtualization sida Cloud Computing ma laha qeexitaan heer warshadeed oo mid kasta iyo qeexitaan kasta ayaa sax noqon kara. Sidoo kale ma laha noocyada caadiga ah si aan u kala saarno saddex qaybood oo waaweyn:

1. Hab-shaqeedka Virtualization
2. Farsamaynta Aaladda Kaydinta
3. Farsamaynta Codsiga

Waxaa jira qaar ka mid ah noocyada kale ee farsamada casriga ah oo soo baxay sanadihii la soo dhaafay oo hadda ku yeelanaya muhiimada meelaha soo ifbaxaya sida xisaabinta daruuraha iyo xisaabinta xadhkaha. Kuwaani waa kaydinta macmalka ah, ikhtiraacida adeega, farsamaynta hardware-ka, kasbashada shabakada, maaraynta maaraynta, iyo kasbashada adeegaha codsiga.^{(These are storage virtualization, service virtualization, hardware virtualization, network virtualization, management virtualization, and application server virtualization.)}

Baaxadda wax-ku-oolnimada ayaa kor u kacaysa oo iyadoo leh hal-dhisme-chip ah oo la soo saari doono dhawaan, waxaan filayaa maalgashi badan oo goobtan ah.

Qormooyinkayga mustaqbalka waxa aan ku iftiimin doonaa noocyada kor lagu sheegay.

What is Virtualization technology?

As a usеr, some of you may be nonplussed by the two terminologіеs which appear now almost at every technical site:  Cloud Computing and Virtualizatiоn. We had covered introductory articleѕ on Cloud Computing but Virtualization has not been covered here. So let’s try and understand what is Virtualization and whаt it offers becauѕe of which it has become a buzz word.

What is Virtualization in computers

First of all, understand that Virtualization is nothing new – it was always there, it had great importance during Mainframe Computer time where it was required to share the resources in an efficient manner, as they were quite costly at that time.

With the advent of time Virtualization lost its importance due to two major reasons:

1. Hardware costs dropped down drastically with LSI and VLSI.
2. x86 architecture became very popular.

In short:

Virtualization is any framework or process or layer which divides the resources like servers, databases, networks, operating system into one or more different execution environments.

It allows users to run single physical resources like your server or storage device to appear that it is running as multiple logical resources. What virtualization actually does is that it abstracts the characteristics of the computing resources so that other processes, applications, or systems can interact with those sets of resources in a non-conflicting fashion.

Examples can be partitioning the drive, using the mobile emulator, or using products like Virtual PC or VMware desktop virtualization products.

Virtualization like Cloud Computing has no standard industry definition and each and every definition can be correct. It also doesn’t have standard types so we can classify it under three broad categories :

1. Operating System Virtualization
2. Storage Device Virtualization
3. Application Virtualization

There are some other types of virtualization that have evolved over the years and are now gaining importance in emerging fields like cloud computing and grid computing. These are storage virtualization, service virtualization, hardware virtualization, network virtualization, management virtualization, and application server virtualization.

The scope of virtualization is rising and with single on-chip architecture to be rolled out soon, I expect a lot of investments in this field.

I will be throwing light on the above-said types in my future posts.
