Which two business and technical challenges does implementing virtualization within a data center help businesses to overcome? (Choose two.)
- server hardware needs
- physical footprint
- power and air conditioning
- operating system license requirements
- virus and spyware attacks
Traditionally, one server was built within one machine with one operating system. This server required power, a cool environment, and a method of backup. Virtualized servers require more robust hardware than a standard machine because a computer or server that is in a virtual machine commonly shares hardware with one or more servers and operating systems. By placing multiple servers within the same physical case, space is saved. Virtualized systems still need the proper licenses for operating systems or applications or both and still need the proper security applications and settings applied.
