VMware is a company that produces virtualization software to allow multiple virtual machines to run on a single physical machine. It was founded in 1998 and launched its first product, VMware Workstation, in 1999. Since then, it has grown significantly through acquisitions and partnerships. VMware software allows each virtual machine to run its own operating system simultaneously, enabling users to test multiple environments without risk to the main computer.

2. What is VM ware?
• VMware Workstation is a hypervisor that runs
on x64 computers; it enables users to set up
multiple virtual machines (VMs) and use them
simultaneously along with the actual machine.
Each virtual machine can execute its own
operating system, such as Microsoft
Windows, Linux or BSD variants. As
such, VMware Workstation allows one physical
machine to run multiple operating systems
simultaneously

3. HISTORY
• In 1998 VMware was barely having 20 employees
and operating in stealth mode, In February 1999, at
the DEMO Conference the company was launched
officially by Chris Shipley, Within couple of months
passing in May 1998, VMware launched its first
product VMware Workstation, and in 2001 they
entered into server market with VMware GSX Server
(hosted) and VMware ESX Server (hostless), Later
company gained good economy and in 2003 they
launched VMware Virtual Center, Virtual SMP
technology and VMotion.

4. HISTORY
• In 2004 VMware was acquired by EMC
Corporation for $625 million, In 2005, they
established two R&D Center one in
Cambridge, Massachusetts and other in Time
Warner Center in New York City.

5. HISTORY
• In an initial public offering EMC Corporation
released 10% of the company’s shares in
VMware on the New York Stock Exchange in
August 2007.

6. HISTORY
• On July 8, 2008, Co-founder, president and CEO
Diane Greene was fired by the Board of directors
from VMware, and elected Paul Maritiz, He had
retired from Microsoft who was heading EMC’s
Cloud computing business unit.
• Later On September 16, 2008, VMware announced
that they are collaborating with Cisco to provide
data center solutions. Couple of months later on
November 26, 2008 VMware acquired Tungsten
Graphics, which was core expertise in 3D Graphics
driver development.

7. HISTORY
• Around 2 years VMware started to collaborate
and it acquired couple of companies, On January
12, 2010, it acquired Zimbra, it’s an open-source
collaboration tool from Yahoo. On May
6, 2010, it acquired GemStone, to be operated
under Spring Source VMware division.

8. HISTORY
• On August 31st, 2010, VMware announced its intention
to acquire TriCipher and Integrien.
• On 26 April 2011, VMware acquired SlideRocket a
startup which developed a SaaS application for building
business presentations that are stored online. Through a
Web-based interface, users can handle all parts of the
process, from designing slides and compiling content, to
reviewing documents and publishing and delivering
them
• On May 16, 2011 VMware announced its intent to
acquire Shavlik Technologies. VMware already used
Shavlik technology in its vCenter Update Manager
product, and co-developed the VMware Go offering.

9. • On 31 May 2011, VMware acquired Socialcast, a
group workstream service.
• On 13 June 2011, VMware acquired Digital Fuel,
IT Financial and Business Management SaaS
Company.
• On 24 April 2012, VMware acquired Cetas
Software.
• On 22 May 2012, VMware acquired Wanova.
• On 2 July 2012, VMware acquired DynamicOps.
• On 23rd July 2012, VMware acquired Nicira Inc.

10. What is a Virtual Machine?
• A virtual machine (VM) is a simulation of a
machine (abstract or real) that is usually
different from the target machine (where it is
being simulated on). Virtual machines may be
based on specifications of a hypothetical
computer or emulate the computer
architecture and functions of a real world
computer.

11. • In short, it lets you use an OS within your OS.
• It splits the physical resources of your computer
and divides them, whether equal or not, between
this two OS which you can run at the same time
which is usually impossible.

12. Virtual machine advantages:
• multiple OS environments can co-exist on the
same computer, in strong isolation from each
other
• the virtual machine can provide an instruction
set architecture (ISA) that is somewhat different
from that of the real machine
• application provisioning, maintenance, high
availability and disaster recovery.

13. Disadvantages of VMs are:
• a virtual machine is less efficient than a real
machine when it accesses the hardware indirectly
• when multiple VMs are concurrently running on the
same physical host, each VM may exhibit a varying
and unstable performance (Speed of Execution, and
not results), which highly depends on the workload
imposed on the system by other VMs, unless proper
techniques are used for temporal isolation among
virtual machines.

14. Why use a Virtual Machine?
• You’re already running a computer with an OS,
so why do you need to use a virtual machine to
run another computer INSIDE of your
computer?

15. No OS is perfect nor the same.
• Linux and Windows are major examples of
different OS which works in entirely different
ways.
• As programmers, being able to test a software on
different environments are crucial, not to
mention that running applications which can
usually cause harm to the main computer may
be done in the confines of a virtual machine
without the risk of losing important files.
