Virtualization Definition:

Virtualization Definition In computing, is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system, a storage device or network resources.

Applications of Virtualization:

Applications of Virtualization Hardware Software Memory Storage Data Network Desktop Mobile Server Cloud

Virtualization Origination:

Virtualization Origination IBM was at the forefront of virtualization in the late 1960s the IBM Cambridge Scientific Center developed the CP-40.

Visualization Heritage:

Visualization Heritage 1960s: IBM introduces virtualization as a way for mainframes to share expensive memory and split mainframes into multiple virtual machines. 1971: IBM begins commercial production of its S/370 systems and adds virtual memory as a standard feature the following year. 1980s to 1990s: Virtualization loses steam as the client-server computing model takes hold and hardware prices plummet even as capabilities increase. 1990s: Virtualization breaks out of the mainframe as vendors such as IBM, Sun, HP, and SGI incorporate the technology into their Unix system. 1999: VMware launches its Virtual Platform product.

Visualization Heritage:

Visualization Heritage 2003: EMC acquires VMware. 2005: VMware releases VMware Player, a free player for virtual machines. Sun’s Solaris 10 is released, including Solaris Zones, a virtualization product that works on x86, x64, and SPARC machines. 2006: VMware releases VMware Server as a free product for the server market. Microsoft releases Virtual PC 2006, a free product. 2007: VirtualBox Open Source Edition, an open-source virtualization offering under the GNU General Public License, is released by innoTek. 2008: Sun Microsystems announces agreement to acquire innoTek. VMware announces agreement to acquire Thinstall. 2009: EMC, Cisco, and VMware announce the Virtual Computing Environment coalition, an initiative designed to promote data center virtualization and a transition to private cloud computing structures.

Advantages of Virtualization:

Advantages of Virtualization can be used to consolidate the workloads of several under-utilized servers to fewer machines provides secure, isolated sandboxes for running untrusted applications can create operating systems, or execution environments with resource limits, and given the right schedulers, resource guarantees provides the illusion of hardware, or hardware configuration that you do not have can run multiple operating systems simultaneously allows for powerful debugging and performance monitoring

Disadvantages of Virtualization:

Disadvantages of Virtualization Single point of failure Need for powerful machines May lead to lower performance Not always feasible

Summary:

Summary “ Computers were originally just supposed to be number-crunchers, but now their number-crunching has been harnessed in a thousand imaginative ways to create new virtual machines, such as video games and word processors, in which the underlying number-crunching is almost invisible, and in which new powers seem quite magical …” Daniel Clement Dennett
